I have the same tractor and the same issue. I will try out your procedure. Even if it doesnt fix my issue, I thank you for showing me some more things about how this tractor operatores.
Thanks for leaving this video up, it really helps. I'm watching again after replacing clutch disc on my L3400dt with 1500 hrs, but after putting clutch petal back to specs like you did at about 22mm of free-play, my pto lever grinds, guess I need to adjust those same two stage screws.......
My clutch disc wasn't completely gone but was sticking in 1st gear, so when taken apart we noticed that one diaphragm spring pressure plate on main clutch disc was cracked. So I replaced both clutch disc, throw-out bearing and two new spring pressure plates, and before it's completely put back together I tried it back and forth in my shop, I noticed the clutch petal feels a bit different and it didn't stick in 1st gear, but pto lever grinds, probably work on it this weekend............
Yes, the pto lever grinding would indicate the need to set the pto clutch free travel, as described in the service manual.
I'm glad that this video was able to find someone in need. Thank you for watching.
@@THEdisgruntledmonk I just got done adjusting my two-stage clutch, I still dont get or understand a 7/6 counterclockwise turn on that bolt, seem so they could make better instructions that makes more sense....
I brought all 3 bolts up to contact of pressure plate, then I tried a 1/4 CC turn and it worked, then tried 3/4 CC turn and that worked, then tried 1 CC turn and I was back to pto grinding again. So I settled on 1/2 CC turn and called that ballpark. The pto lever goes in easy without grinding, and turns pto shaft when clutch petal is released a little and tractor dont start to move til petal is almost all way out.....
PS I had to make a temp plate that bolts on to that loader mount and pins into floor jack, I couldn't hold it steady by my self. Kubota didn't skimp on loader mounts on the L3400.....
Just a thought... if the bolts have 6 flats then for 6/7ths you could count the flats (7 times). Hope I don't have to take my loader off. Thanks for the video!
Thanks for the video. How many hours is a lot on your tractor? Which model number is your easy hitch. Curious which one is the best for this model. I have a 2015 L3400.
The hitch is a land pride qh10. The tractors got 3700 hours on it. Its not a ton but its a lot. Kubota stopped production of the L3400 in 2010, so what tractor do you really have?
Will this adjustment help if my tractor clutch isn’t engaging enough in higher gears ? my tractors doesn’t want to move In 3rd or 4th gear , and needs full throttle to move in 2nd gear . I got a l3901 manual 4wd
I'm sorry to say, I think your tractor's clutch might be fried. As a last ditch attempt you should look in your manual for the section that talks about clutch pedal adjustment, and give that a try. If the tractor's clutch pedal doesn't have any free travel, it can induce clutch slippage and permanent damage if not dealt with urgently.
Whenever I work on my Kubota, I enjoy doing things 4 times over.
Did you have to do anything else other than connect the pto shaft. I normally have to give my 3400 a pretty good quick pull to engage the pto otherwise it will make the grinding sound like yours did if I attempt to slow pull it. Im trying to see if I need to do this adjustment on mine. When my pto is engaged and I press my clutch pedal in and release it there is a very pronounced click sound when I release the pedal. Other than that everything functions as normal.
It sound as though you're tractor needs this adjustment. If your PTO lever grinds even when your pushing your two stage clutch pedal all the way down, you can follow my video as a guide.
If this doesn't answer your questions please write another comment.
Mine acts identically on my 88 L2550.
and mine in L3600.
Oops! I meant 7/6ths on my previous post
Yes I could have counted 7 flats, good idea.
I have another question. I just purchased my third L3400 and it has the same issue as yours after you showed the first adjustment. When you try to engage the PTO you can feel the gears still turning. What did you do different after your first adjustment to fix the problem? Did you have to tighten it further or did you adjust it in the wrong direction?
Yes, the adjustment set gap for the PTO Clutch needed to get closer. This one ended up at about a 1/4 turn out from bottomed out. If this doesn't answer your questions please write another comment.
What did you find to be the best way to BAR the engine over? So instead of a little over a full turn on the bolt (7/6) , you only needed to go 1/4 out? Another thing that is real common to go bad on these l3400 is the return hose just above where you were working. If you hydraulics start acting up ie your steering and bucket, your hose has a crack in it and needs replacing. @@THEdisgruntledmonk
@@jjgag601 in the video I didn't show it, but I took the panel covers off the engine and pulled gently on the fan to get the engine right where I needed it. Yep, only a 1/4 turn out on this tractor, bearing in mind 3700 hours. Hmm... yeah I watched a video that mentioned the suction side hose issue. If this doesn't answer your questions please write another comment.
my L3600 also had that problem because of the return hose
So why was the the PTO gears grinding after you adjusted clutch?
The reason is explained at 27:26 in the video. I acknowledge that part of the video is out of logical order. Meaning the video explains an answer to a question that hasn't yet been spawned in the video by the segment showing the grinding of gears.
None the Less I hope this video was educational for you, and if not maybe it was entertaining. Thank you for watching.
@@THEdisgruntledmonk Gotha, you must be good at Jeopardy. My duel clutch is working like it's suppose to, but but after 900 hr my 1st gear in low and high sticks in gear, I have to hold brake and jerk the clutch petal to get it neutral, such a pain. I now have 1400 hr so maybe next year I will change clutch..........
Make some guide bolts when you put it back is just smart and safer
Thank you for watching, I'm glad you enjoyed the video.
Thanks for the recommendation.
Thing I see is people riding the clutch pedal, resting foot on it will end the lining very quickly
