- This video may help you see how the transmission belt is changed on a Cub Cadet LT1045 Riding Mower. The owner's manual says take it to the dealer for service. I refuse to do that.

Incredible design here, absolutely adore the simplicity to service a high wear item on their product. Outstanding
Wow I swear TH-cam is the best thing ever. No matter what random thing that I break someone has a video on how to fix it. Thanks for making this video. Wish me luck.
If your pulley comes off then you don’t have to unbolt the engine. Most pulleys get stuck though. Hope it works for you.
No need to loosen the motor. The drive pulley simply slides down for easy access. The rest was very helpful. Thanks for the video.
I’m trying to get the drive belt off my LT1045 , I found your video & this is exactly what I needed Thankyou for posting God Bless
We just changed ours. Had watched the video but had also printed out some directions from ehow. The only difference was instead of bending the tabs or loosening the engine, the printed directions said to pull down on the pull that is above the PTO. Came right off and made it a breeze. We also took off one of the rear wheels and that made it much easier to get to the rear and over the fan blades.
Thanks a million. Worked perfectly. Lot easier than trying to get the pulley off.
This video helped me a lot. I appreciate the simple and common sense approach to do this. It will save me a LOT of money doing it myself.
I'm glad the video helped you. I am still learning how to edit the videos better. I do try to get to the point with no fluff!
thanks for the video, it really helped. i have to pull a whole engine out of a cub cadet LT1042 and put it into another cub cadet LT1042. watching this video helped me understand how to drive belt goes on and works. thanks :)
Thanks for posting - a great help :) My lt1042's drive belt slipped off the front pulley after a tiny twig got wrapped around it. An 18V impact wrench and 16mm impact skt took the PTO bolt off easily and the pulley slid down the slotted shaft without having to lift the engine up. My machine's only got 20 hrs on it though! Thanks again didn't have to go near the dealership :)
I was using my LT1045 for what is likely the last project of the year before winter and the dang belt came off. It was all tore up so clearly it was just a matter of time. I will be ordering the belt now but unless I get some more good weather (Wisconsin), it will have to wait until next spring for the fix. I am soooo happy to find your video. I watched three others and yours looks by far the simplest and I really appreciate the "getting to the point" and lack of BS fluff on many of the others. Clean language is a big plus as well.
Hey. Thanks for the nice comments. I like to try to get to the point. I can’t stand long videos. I will be doing another video on replacing the deck bearings for $30. I noticed the left blade was leaving uncut grass. Found the blade not spinning freely so I bought all new bearings to do all three. Look for it soon.
Many thanks - I was doing some other repair work on my Father-in-laws lt1045, and noticed the belt was in need of replacement. I probably would not have tried removing the four engine bolts to get better access if I had not seen your video. That was much easier than using a gear puller to try and get the pulley off the crankshaft. Like another commenter, I was carefull in putting the bolts back in so not to cross thread them - by gently moving the engine with a screwdriver pried up against the side of the pulley to insure lined up perfectly straight. Once again... many thanks!!!
AB Kansas Glad the video helped you!
Thanks so much for making the video and sharing with us!!! Getting ready to tackle this on my 1550 and they are probably the same design. W
Very helpful video, about to do the belt swap on my LT1042.
Thank you!
Thanks for the video. I will change it myself now instead of taking it to get serviced.
Thanks for taking the time to make the video. I looked under there and saw the unfriendly, to the do-it-yourself guy design engineering, but your video pointed out the hurdles to expect. I also liked that you showed the replacement belt number. The only thing I would have added would have been the model year that you were working on as the parts dealers make a differentiation between pre and post 2008 parts. It may or may not effect this particular part and it's replacement. Thanks again for taking the time to post.
Wish I would have found this video 2 weeks ago,..I slap some vice-grips on those guards surrounding the pulley and bent them back,.put the belt on and just bent them back into position,..I never thought about moving the motor,.It worked but I will remove the engine bolts next time,..thanks for sharing !!
I have an LT1050 and plan to replace the drive belt ... thanks for the video you've been a big help
Glad it will help you!
Overall a very helpful and no bs DIY vid. Thanks!
A few of my takeaways from the R&R:
- Fully removing the PTO dual pulley assembly down and off the vertical crankshaft pulley is advisable for greasing the shaft during belt R&R. Do NOT forget the SPACER that slides on the shaft between the engine block and pulley assembly! It is oriented WIDE side UP [edit: MINE was flange up: other vid showed flange DOWN. Doubt orientation matters...]
- Be very deliberate when re-installing the PTO bolt; it can cross-thread (ask me how I know, grrr). Advise against using impact wrench to install anything into any engine block: pros use hand drives + torque wrench for good reasons during block installs.
- On a 1045, removing the underseat battery and its support bracket is essential. There's a circlip retaining the rubber fan above the trans which is FUN to remove: i used an awl to secure one of its tiny holes and then a slot screwdriver to pivot the circlip off (the awl prevents it from flying away). After circlip is removed the trans pulley easily slides upward for belt R&R.
Stupid and annoying design, imo.
I appreciate you and your video. It really helped me set my expectations and to schedule the time needed to make the belt service go smooth.
Thanks for the kind words. Glad it helped you.
LOL, i was worried i would need an impact. Welp, better go get the old neihbor guy of the couch to go find his, so i can borrow it! Thanks for the help
Well done video! No fluff and didn't waste time! Many cudos!!
+Edward J Fernandez Thanks for the kind words! Glad the video helped you.
Thank you for this. Just got a used (2005) LT-1045 and threw the drive belt and this vid made things fairly easy-peasy. Thankfully the PTO came off with no problem as that was the only part I was a bit worried about.Now if I can just figure out how to keep the idler pulley bracket bolt to stop loosening itself and throwing the deck belt...
I have another video showing how to fix the deck belt from flying off.
Great video! Thanks! Your method, is a whole lot easier, than trying to take the upper pulley off! Nice to know that there are 4 bolts to remove, to lift the engine up. I don't know why Cub Cadet, didn't just make bolt on belt guides, instead of frame mounted tabs? My belt, is original, and is cracked, seven ways to Sunday, with missing belt chunks! If I didn't tackle this, when I was ready to change my deck belt, yesterday, I can see myself, trying to push the beast across the lawn, after it snaps, and I am sure I wouldn't be in a good spot, as my luck works! Should be easy, since I packed in my frustration, at dinner time, last night! Thank you, so much!
Doug B I'm glad the video helped you. I try to make videos straight to the point.
Fix Them Things! One thing that didn't surprise me, is the one bolt, that is hidden, yuk! I have decided to undo the exhaust, at the engine, to help me swivel the engine, since it does restrict movement. I did loosen the hidden engine bolt somewhat. After lunch, I'll see how it goes. I've got a dose of Kano Kroil, penetrant on the exhaust bolts, in hopes that it does not give me problems. Fun times!
Thank you for the video! Know exactly what I have to do now.
Awesome video. Thanks very much!
thanks,. you made it look easy!
Thank you! Thought those tabs had me beat.
Excellent. Thank you.
My mower just lost its drive belt. About 10 years old. That must be the time they go. Not looking forward to this work. Thank you for the helpful video.
WOW my mower drive pulley comes off once the belt is off. I just did this yesterday on my LTX1050. After removing the deck I jacked up one side of the mower and secured it with tie down straps to the rafters of the garage. That worked great. I didn't have to hang the clutch by a spring. I disconnected the cable pig tail connector then remove the bolt and pulled the clutch off of the drive. With my mower I didn't have to bend the tabs that are around the drive pulley because the pulley slides right off once you loosen the belt.
Donald Joseph Wood I just did my friends belt the other day and his pulley wouldn’t come off so I did the same thing my video shows by unbolting engine. I hate when people bend the tabs. That’s just lazy. You are lucky the pulley came right off. I hope my video helped you. It’s pretty easy to change this belt.
I didn't have to loosen my engine bolts my pulley slid down the shaft nice and easy belt came with it maybe PB blast shaft and a couple taps
Thanks heaps! Legend
Thank you👍
Great video.
Trying to do mine now, but can't get the PTO bolt off to save my life. At first I thought it might be reverse threaded, but as you indicated in a comment below, it is not. The only impact I have access to is a Milwaukee 18v. Thought that would surely work, but I can't make it happen. Any suggestions? I really don't want to take it in for such a simple fix...
Thanks!
Good video of what I thought I had to do to lift the engine up.. But my PTO did not just fall off... I had to pry it off as the the top bearing was well seized to the shaft... is there a better way or special puller to pull the PTO off...
Glad the video helped! Not sure about the puller. After removing the bolt that holds the pto mine came right off. The pulley should stay on the motor.
Thanks for the video and PLAN B for if the front pulley won’t pull down. Im a newbie to doing my own repairs. What kind of grease did you use for steering ? Dielectric grease? Can you use anti seize grease on these pulleys?
Yes. You can use anti seize on the pulley shaft. I would just use regular grease on the steering. Same grease you use in the wheels.
The engine pully also slides off. you don't have to unbolt the engine (or bend the tabs as someone else said). they get rusted on, so spray it good with WD40, let it set awhile and it should slide off.
Easier way!!!!! Started removing the engine bolts and noticed nothing holding the pulley in place such as set screws. Grabbed it and it pulled right down on the shaft. Easy enough.Cub Cadet thought of that. Had the deck off so a good time to lube it and sharpen the blades.
My belt looks the same way. I just wanted to make sure i needed to remove the PTO...thanks. But you should have concentrated on how to install the new belt...taking off the old one required one snip.
Well I ordered a belt for my mower. Got a genuine cub cadet belt too. Hopefully I can figure out how to install it. The big question is will a impact screw gun be enough for the PTO bolt or do I need an air impact because I don't own one. Had to use a breaker bar and 6 foot pipe to get the blades off to change.
Not Bad Run 10yrs out belt..! Just replaced mine on 2006 LT1046 Cub Cadet 11yrs out of mine
So based on your belt numbers you pulley on the transmission is 4.11 diameter correct? In my opinion your method only way to do it. Thanks for the effort.
Thanks FTT ++ Bolt / Socket sizes would have been helpful, The PTO / Clutch bolt ?
5/8
I bought a Cub Cadet LT1045 back in 2008. After seeing this video and a few others, I wish I had never bought it. Having to unbolt the friggin' motor just to get a drive belt off? Seriously? I've already had to re-do the belt drive on the mower deck, had to fix the park brake because it was locked and wouldn't allow the mower to go forward or back, and now my drive belt needs to be replaced and I find out it's a big hassle too. I'd throw the thing away if it didn't have a Kohler engine. That part has never failed me. After 11 years of mowing, the motor is still strong and runs like new. But the rest of that pile of junk...
Some people are able to change it without lifting the engine as their pulley will fall off. Most people will have stuck pulleys like I did. My cub has been really good. Rolled it over twice down a hill and turned back on with no problems. Only problems I had is 2 drive belts and one deck belt but I maintain very well. 15 yrs old now.
I don't have impact tools, can the PTO be taken off with a big breaker bar?
Also, you made it look so easy...anything else non mower mechanics should know or pay particular attention to when replacing the belt?
It has been a while since I did this but you should be able to use a pipe wrench to hold the pulley while using the breaker bar. Just don't damage the pulley.
+Fix Them Things! thank you! And thanks for making these videos, very helpful.
Have the same tractor and when the engine is running I can hear a clunk clunk clunk sound from underneath that speeds up when I change throttle speed. Have a belt picked out just need to order it then hopefully I can get it on. Looks like you dropped the deck to do this. Wondering if it's necessary or can I just unhook the PTO belt. Just changed my blades a few weeks ago too and now this.
Removing the deck will make it way easier.
How do you get the PTO nut to not spin? Take apart the engine cover and jam the flywheel?
Richie Sun I used an impact. If your using a socket wrench you can try to hold the pulley or stick a rag between the belt and pulley.
Most of this is correct except for the part about taking the motor loose. The pulley will slide down the shaft enough to put the belt on.
John Day most people have stuck pulleys. You are one of the lucky ones.
@@fixthemthings I just tapped on it with a plastic head hammer and it fell off. I replaced mine and my uncle's and neighbors the same way. But your video was better than some of those who laid the mower on its side or straight up in the air or the one guy who said that taking the deck off wasn't necessary lol.
So i can only get access to 2 of the bolts holding the motor on . The rear two are under a bracket that hold the steering spindle. Any ideas?
I was just out cutting with mine.. and it STOPED in its tracks no forward or reverse. The gas pedal seems to press down to easily Engine sounds great turns on no prob blades engage no issue it just WONT MOVE.... could this be my issue?
Sounds like your belt did break or came off. If your belt is still on, then the hydrostatic transmission may have failed. Let's hope for a broken belt.
howto.removedeck on 50 inch 0 turn2005model
Not sure why those tabs are there, I am considering cutting them off instead of unbolting the motor
Leo Verran I wouldn’t cut them off. It’s only 4 bolts. Try to see if your pulley will come off first. Most wont budge but you might get lucky.
Hi, Is the pto bolt reverse thread? It looked like you had the impact in Forward. ?
The PTO bolt has standard threads. CCW to unscrew it.
+Fix Them Things! thanks. seemed to back out some but stopped. should have just taken it in as it's under warranty but didn't think it'd be so difficult to put a belt back on one pulley (piece of debris mist have dislodged it somehow)
Got it. Not enough air on the impact. Switched compressors. Thanks again. liked and subscribed!
Once you get the 4 bolts of the engine what tool do you use to move it shift it up? Do you just use a crow bar?
rfedeleon yes use crow bar or just lift it. It's not too heavy. Put a small piece of wood underneath motor to put the belt on then take the wood out. Hope this helps.
I have a 10 year old LT1045 and just replaced both my drive belts. The transmission drive belt is the hardest. However, I did not have to move the motor. The pulley just slides down on the shaft and you can slide the belt right on and push it back up. Perhaps the pulley in the video is seized on the shaft.
Christopher Franklin yes it was seized. Was less damaging for me to unscrew 4 bolts on the motor than to damage pulley.
I use a brass rod to bend the belt keepers out of way. much easier and faster for me
thanks,i did get an impact wrench.came right out. those belt guards i pounded open with a long screw driver, then closed them by pounding them back. what a pain in the butt CUB CADET!! im now trying to sell it or trade it in. CUB CADETS SUCK ROYAL!!!!!
+Kevin Aalberts ...... I agree Kevin...it's a piss poor design by Cub Cadet when the service manual tells you that you need special tools to replace a freakin' drive belt. I have a Craftsman also, and you don't need any special tools to replace it. Now I know why the guy sold me this tractor......everything you go to do is a pain in the ass.....Blade belt jumps off if you don't have the motor revved up.......I guess this is so it will stretch your belt so you have to buy another replacement.......Nothing about Cub Cadet that I like..........Will never buy another!
Agreed! Deadman Walkin! Ive had it in the shop many times.no one should be saying that about anything you buy! Next time there will be a John Dere doin the yard work at my place!!! They are also way over priced but....
I tend to agree on cub cadet sucking . I have a ltx1046 that only has like 120 hrs on it an the drive belt i just noticed today has chunks out of it . Im amazed at what a pain in the ass it is to go about replacing it . I havent done it yet . Just ordered the belt a lil while ago . Hope i can do it . Really dont wanna pay a shop cause there rates are unreal .
just drop the pulley down the shaft, put the belt on and push it back up. No need to bend and pound anything. Nothing like doing bubba repairs and the bad mouthing the manufacturers because you make it hard for yourself.
The pulley on the motor actually will slide down, you don't have to loosen the motor and lift it up.
Just did mine and use a pulley puller better then taking off the engine bolts
Used an Impact driver
exactly lasted 10 years also !
I have a cub cadet LT1045 tractor it won't go in reverse. It drives in forward good .What could it be?
+Tim Pazdziorko Sorry for the delay but I can't reply to comments through my phone for some reason I have to log on through my computer. As far as reverse, with out looking at my machine, I would think either the linkage from the pedal to the transmission is not adjusted correctly or the transmission is faulty. I'm sorry, I haven't had this issue yet.
I have replaced mine twice last summer ..the belts keep breaking...have an pointers on why this keeps happening??
Jeff Barnum I would say you probably have a bearing locked up or about to lock up maybe on the tensioner. Do you smell a burnt rubber smell? Maybe a damaged pulley?
Have checked the pulleys every time I've replaced the belt everything is free and not seized. I have never had issues like this!!!Been repairing lawnmowers,tractors, etc..for many years. My customer gets about 2hrs into a cut notices the smell and then drive belt is toast?...How are you routing the belt through..never really covered that part in your video..Do you have to remove the steering linkage to get the belt through?
How long did it take you to replace your drive belt?
I would say 30-40 minutes.
I have a 1042 cub cadet put a new drive belt on today and it not as fast as I have seen in video I did check 3 times to make sure the belt was the right size it should move faster anyone can help me ty great video!!!!!!!!!!!!
MegaFireman50 all I can think of is the tensioner is not tight enough and the belt may be slipping. Check the tensioner.
ok ty will do!!
I just bent the tabs away, slipped the belt in, and bent the tabs back
bY bending the the tabs did that prevent dropping the clutch?
I already had it off by then
Thanks for the video........I figured somebody would have one on TH-cam........this is a piss poor design by Cub Cadet......they just want you to take your mower to their dealer for some easy cash. Shouldn't need special tools (per the manual) to change a freakin' drive belt. I have a Craftsman's also and no special tools are needed to change any of the belts.
i turn the bolt on my PTO, LT1040. and the engine wants to turns over.bolt doesn't come out. it just turns with the engine. help!!!
You will need an impact wrench to get the bolt out. You could also try to lock the shaft with some pliers to keep it from spinning.
yup got it right out with an impack wrench. But i was askin for help um.....days ago!!! :(
+Kevin Aalberts Did you wire transfer funds to the poster of this video to pay him for his time for making this helpful video, and for a timely response to your question? If so, you have a legitimate gripe!
+zackgtrplr
I have been using TH-cam videos for years to help me with things and thought I would make some videos of fixing thinks to give back to the community. Thanks for saying what I wanted to say.
Most of you fail to say which side of the the steering rod the belt is fed???😶
no need to remove motor bolts bend the tabs around pulley much easier they are only there to keep belt in place when it gets crappy and loose like the one in this video
Did you ever think of actually doing this on an LTX1045, instead of one that you think is the same?
I just finished my LTX 1045 , Hardest part was getting bolt out of clutch. I used a impact wrench and it sill took quite a while. Once the bolt was out I wriggled the clutch pulled straight down and it came off easy. The belt pulley just came off no problem. Guess I was lucky. Was not stuck on. I was going to try a video but not good at that. Did not have to bend tabs, or remove engine bolts like others say. Good luck.
Also used a long handled screw driver to place in the slot on the fly wheel to hold it from turning while freeing the bolt , don't place in the plastic vanes.
They are junk. I bought one about 7 years ago and have had all kinds of trouble with it, a GT 1554. It's a lot easier to replace the belt if you can hoist the mower with a lift or turn it upside down. If you can loosen the crankshaft pulley you can get the belt on. Taryl Fixes All on youtube has the best videos on how to do this job.
This is an old post, but there is an update. At the 1:12 mark, you do not have to remove the engine mount bolts. That hidden pulley sits on that rod, just pull it down and it comes off. It sits in a key-hole lock, so just wiggle it, or bang it if it is stuck.
As well, don't bother fishing out the old belt, just cut it, and pull it out. Not only is it faster, but you can then measure it against your new belt to see if it is the right size, and get the correct one if it isn't.
As well, there is a ton of grease and crap under there. add at least 30-60mins for cleaning all the crap you could not see....and yes, you really should clean it out. Grease everything that should move freely. It will be another 5-10yrs before you get under there again, so do it right.
As well, now is a good time to put in some washers in both sides of the steering linkage, greased up, to clean up all "the slop". You'll love the new feel of the entire steering. its much better.
Lastly, FTT used a impact gun to remove the PTO pulley. If you don't have one, there are posts to stick stuff in the spark plug hole, thereby seizing the engine and then taking off the pulley. DO NOT DO THAT. Its never a good idea to put anything in the cylinder. I tried it, out of curiosity with string and it failed, so I tired CAT-5 wire. It got stuck in the cylinder and I felt like an idiot thinking I just added 10hrs to the job to remove the head. The MUCH BETTER way is to just wrap any strap (like a ratchet strap) around the flywheel for friction and then fold over the end about 4 times and jam in in the gap where the ignition unit it. Both are solid steel, so nothing will break. Now you can remove the PTO bolt easily. Simple reverse the strap when putting it back.
also if your real good you don't even have to remove the cutting deck
fit craftsman lawn tractor
.
My stupid fucking belt tensioner spring came off and I don't know where it hooks to the body
you do not have to do all that. you lower the mower deck, take off the old belt up from front pulleys, go in under the battery to take it off the back pulley. Not as hard as this video made it.
Phillip & Glenda Shemphillard you must have a different mower. My battery is up front and you can't get the belt off of the front pulley on mine unless you lift motor, bend tabs or remove the pulley. I thinking your mower is a different year or model.
Fix Them Things! yes your right. your video did help show certain things we were confused about after taking the old belt off. Thanks for sharing
Anybody who buys a "cub cadet" today, deserves every stinking rotten time consuming dollar dropping headache that comes along with it. Cub cadet is a piece of shit. It wears out fast no matter how well you treat or maintain it. Not to mention the tinshit that it's made of, and the Chinese parts that come along with it.
Did it ever occur to you to just drop the drive belt pulley and slide the belt around it then slide it back
Dont believe everything you see
😂😂😂😂😂
Yep. It was rusted to the shaft though.
