B6100 Clutch Replacement

[KubotainNH]

TexJer, sorry I didn't see your question earlier. I did not touch the bolts on the pressure plate itself. The adjustment on the outside doesn't take much to make a big difference. If I remember correctly, you want about an inch of pedal play where ever that ends up on the threaded rod. I think if you have it all the way out then you are pushing on the fingers without touching the pedal which would make for slippage. I would thread the adjuster in a ways and then slowly spin it out until you get the pedal play where it needs to be.

The loader actually made the job easier because of the added weight in front of the wheels and extra places to put a jack. Good luck.

I just replaced the throwout bearing in my B7100. I used the propeller shaft to realign the clutch at the suggestion of a Kubota mechanic, and it seemed to work good. The shaft should slide forward out of the spline connector at the rear where it goes into the transmission so that you can put it through the clutch and into the pilot bearing. I also found I needed to replace the pilot bearing, Kubota calls it a 'bearing, dry'. There is a seal next to the pilot bearing that should probably be replaced as well.

Same here when I changed the clutch on my b7100 gear, that shaft will come forward enough for you to use it to align the clutch pack. My pilot bearing didn't really look that bad but I had ordered all the parts before taking the tractor apart so I replaced it anyway.

I've got the pedal adjustment all the way out. I started taking her apart yesterday and hopefully will be able to split it this week. I work nights, 6 pm to 6 am so my "free time" during the week is limited. We've been getting a lot of much needed rain here the past couple of weeks so not having the tractor hasn't been that big of an issue.

Yea, we took the shaft out and used it to align the clutch and pressure plate. I'm going to get on a lathe tonight and make me one of those measuring tools to set the fingers with.

This is the part that's confusing me. You say all the way out but it needs to be in farther if the clutch is slipping, not out. Maybe I'm misunderstanding you. If you look at the attached picture, especially 10.3, the threaded rod with the "adjustment of play" arrow is the one that should have threads showing out the end toward the front of the tractor. This will move the bottom of the clutch lever toward the back of the tractor which is what you want.

Sorry for the confusion. I have NO clutch.......it won't disengage. I have to idle the engine down and "slip" it into low gear. It's like the throw out bearing isn't engaging the fingers on the pressure plate. I'm going to copy and print the picture you sent to use once I get this figured out.

THANKS!!

To answer Allenr,

The new B2630 and B3030 do not have a clutch or mechanical disconnect but just a drive plate. The only way to stop it is to center the hydro pedal.

Most other Kubota hydros use a dry clutch. In a panic stop or for ease of cold starting, it can be useful. It really is along for the ride most of the time.

The old IH hydros used a flex plate to drive the input shaft and the clutch pedal was referred to as a "foot n inch pedal - for inching. It controlled the opening of the relief valves and had no mechanical connection elsewhere.
