2 things that helped me, the bottle jacks only worked with the handle on the bottom, and a pick and hook set was necessary to get the seals out. Great video; I couldn't have done it without it.
My 3 ' long 3/4" drive breaker bar wouldn't begin to budge the 1 1/2" axle bolt. I don't have a high torque 1" drive air impact so I ended up using a torque multiplying heavy truck lug nut wrench which broke it loose easily. The chassis bolts on my 773 prevent the jacks from being positioned exactly 180 degrees across from each other against the hub flange. At first it wouldn't come loose after loading the bottle jacks and hitting the axle bolt with the sledge. The 2nd time I gave it a few whacks on the back side of the hub flange between the long gap in the jacks and it popped loose. I cleaned up the axle with some emery cloth. The other hub flange wouldn't come loose no matter how much force I put on the jacks or beat it with my sledge hammer. I finally put a large gear puller on it and torqued it as much as I could. Then I swung the sledge under the chassis below the engine and hit the back side of the hub flange with enough force to knock it loose.
Do you have to drain the oil first?
Thanks man!!
Same method for an old 732?
I have an S300 2003 yr. im being told I have to pull the axle to access the seal and bearings?
Bearings yes, seal no
Hi I have a 863 that has a axle seal leak as well. I have 3 bolts in my hub ,unlike yours that has 1 in the center. Is my axle similar? Was hoping I didnt have to open the chaincase to pull the axle. Any advice is greatly appreciated.
Yes it works the same way but don't hit bolts with hammer. Try to hit hub from side once the jacks are installed.
@@tetradgroup Thank you.
Your a bobcat goldmine
Do you by chance have a part number for this kit with speedy sleeve for a 2015 bobcat s550?
I've just managed to get all four hubs off and seals out thanks to your video. Off to bobcat tomorrow to get 3 seals and 1 seal kit as I will need a seal saver for one only. Thank you nice easy to understand vodeo.
Thank you for the video what's the torque on the bolt
Would the s650 be the same design
Does i=that work same way for a bobcat 743?
How does pressing back not damage the bearings ?
Perfect video on this seal replacement. Great explanation, and easy to understand!
I really enjoy your videos keep them coming I’ve learned a tremendous amount
That was in my opinion the only way to do that job, can I just say thank you for going to the effect making these videos as I’m sure you are helping people worldwide even down under mate
Sealant under the speedy sleeve. I've had more than one instance where the slightest gouge on a shaft caused a perpetual leak. Its hard to get a good look all the way around a shaft. I'll add sealant to the OD of the seal if I have ANY concerns. Lot's of guys operating like the bull in the china shop. Always a dinged up sealing surface somewhere.
Thanks good video will be doing one on my old 722 tomorrow
As far as changing the wheel seals, I yet have a problem. I have a bobcat 643 early serial number 5015-m-11727, and my seals are inside the chain casing. Looks as though the hydro drive needs removal to access. YIKES
Your videos are very good. I've learned quite a bit watching them. You explain things very well. Thank you.
I have an 843 front wheel leaking badly, my guess is a wheel seal/bearing any suggestions.
Axle seal for sure, raise machine and see if you have any in and out movement of the axle. If you have any play then it's time for bearings.
Does oil need to be drained to perform this repair. Thanks very helpful and informative video.
Great video. Will this method work on a 1977 M-371?
Just did new seals and 100% that the repair sleeve is on backwards and no seam made to break off the flange. flange is meant to go against bearing. I mean this way worked, but definitely not the way on the bobcat instructions with kit. Would be worried about metal edge break the flange off and catching the seal at some point.
Yes you are correct, this is not how the sleeve is supposed to work but its also not designed for this type of shaft. Everyone I have seen has the outer flange with a seem and I have broken the flange piece off to the inside several times trying it the other way. Keeping the flange to the outside ensures the sleeve can be installed all the way on to the shaft without breaking.
Thanks brother. Today we took a great support from your video. Thank you once again.. good luck..
Thanks for posting this...
Здравствуйте, подскажите пожалуйста размер сальников? Или их номер, спасибо заранее
Thanks man. Couldn't you have used a bigger hammer!
I am getting ready to replace wheel seals on my S160. Where did you get the wheel seal saver?
It's part of the Bobcat seal kit. shop.bobcat.com/axle-sleeve-repair-kit-6722907
It looks like you tried the cheap Chinese blue seal then you went and bought the OEM after it failed. The perfect situation for the saying "cheap is expensive".
I'm gonna split the difference and go with Timken or SKF instead of the Bobcat seals, I definitely would stay away from Chinese or off brand seals though.
Thank you sir
Very helpful video
how do you change the bearing
Thanks for the making video
thank u
i saved my money with your video
I see wear ring as in parts breakdown? Is that the speedy sleeve ? I have a rough surface where the seals roses as well so curious
Yes the wear ring would be the sleeve.
It's hard to tell, varies between machines, just not to tight however I run new tracks tighter than normal because they wear in quickly and will be perfect tension after a few hours of run time
Is the seal in your kit different from the seal that would normally be used?
In most cases yes you will have a different seal if using a speedi sleeve wear ring. Check parts for your serial number.
Thanks for video.
Good infomative video
Very nice good job dear sir
D
Great information.
Thank you, sir.
Where did you buy your kit ! Have 873 bobcat
I got mine thru the dealer, kit comes with sleeve and seal
Why couldn't u just put the seal in?
Usually you can just replace the seal but sometimes the axle shaft is scared and will quickly damage a new seal if not fixed correctly.
Just curious how well this repair has held up?
I've used this method for years and it holds up very well. Low oil or debris around axle hub like string and wire can damage the seal as well. The speedie sleeve can also be replaced easily.
Good video! I have a bobcat 753 with a leaky seal. Ill bet that speedi sleeve is the same size. What size is that and where did you get it? Thanks!
It's comes as a kit from Bobcat, I'll try to get the part number for you
@@tetradgroup No need, Ill call the dealer! Thank you!
@@tetradgroup I believe this is the # what they call an Axle Sleeve Repair Kit # 6722907. I am getting ready to do a 773G this week and was looking at part #'s for bearings, seals, races last night (in case I need them) and I saw the sleeve kit for $48.36 on the Bobcat site as of 2/12/22.
Nice educational video.
Do you have a video on bearing replacement?
Yes I do
th-cam.com/video/z0maGeji4YY/w-d-xo.html
@@tetradgroup thanks for the link to your video. My local Bobcat dealer quoted me 900 dollars per axle to replace the bearings and seals. 3600 dollars seemed a little steep. This would be a winter project so I wouldn't be rushed to get it done.
My axle is leaking and has about a little less than 1/4 inch play in and out, no play side to side. Do you think it will need bearings?
The axle will preload the bearings when torqued down and any play in and out would suggest bearings are worn and should be replaced.
Hello, Just out of curiosity, did you drain the oil first? or jut the angle did the trick?
I was jacked up enough so oil didn't drain out of the tube. It was actually low because of the leak. I added about a gallon of oil after seal was replaced.
Thank you so much for the info. I am wondering, because mine is on perfect level, so not sure- I wonder if it is getting refilled from the reservoir, which I have had to refilled a bit after I replaced the pintle arm seals, and the tilt cylinder seals.
