GR 2110 PTO not fully engaging

[captainslav]

Hi Fellas, first time posting, long time browser.

My problem is when I engage the PTO on my GR 2110 for my mower, the PTO turns and tries to get up to full speed, sometimes it does, other times it does not. If the PTO does not get fully up to speed the motor will bog down when cutting grass. When it does surge to full speed, then it will not bog down at all. I dont even know if i can post a link to you tube to illustrate the problem but here goes nothing https://www.youtube.com/watch?v=-wYCuXpTA1U

Is this a clutch pack problem? Thanks ahead of time for your help.

Sounds like a clutch pack problem. That or a linkage adjustment, but knowing what I know of that transmission (and it's history), I'd lean more toward a clutch pack issue....

Thanks for your response, i have fully adjusted the linkage..if i could adjust it more, i think it would help it to engage fully.

The problem also gets worse as the transmission heats up, it will surge to full speed much quicker when things are cold, but when the transmission gets warmed up, it wants to hang on to bogged down slower speed.

If i replace the clutch pack, is this a job that i can handle or is this a definite service by the pro type job? I have no experience with clutch work but consider myself fairly capable.

Thanks again

Would i have to remove the rear differential to replace the clutch assembly?? That may be over my head.

I "think" it can be done in the frame, however, I would suggest removal of the entire transmission and do it on the bench.

OK, so i just removed the whole PTO clutch and found some pretty good wear on the clutch plate as suspected.

But before i started i drained my transmission fluid via the drain plug then removed the suction line and removed the HST strainer body and shook it out and all this grey gasket material fell out and kept falling out till i had a pile like this:

Anyone know how to remove the strainer completely?
The bronze bushing seems to be pressed in, i cannot spin it or anything though?

Thanks for any insight you can share

The gray stuff is the gasket. It is called "liquid gasket", AKA Silicone. Kubota uses a lot of it in places rather than a traditional gasket. The transmission case is sealed with liquid gasket, and when assembled, some of it squeezes out and gets into the transmission. No big deal-that's what the screen and then the filter is for.

I had a chance to buy a really low hour GR2100 diesel last week, that needed transmission work. I could have bought it for $900. Had 134 hours on it. I probably could've flipped it and doubled my money. But I passed on it...I hate them. The only thing I like about 'em is the engine and they have great cut quality. And that's it.

Any way to remove the screen from the casing?

No real idea but you can look at the illustrated parts list at Kubota.com to see if they list it as a separate part. Which way does the fluid flow through? Back flush from other side (reverse flow) and that may get it to loosen up.

My PTO failed recently. I immediately ordered a service manual DVD online. It quotes specs for the clutch plates.
I pulled the PTO out of the transmission with only removing the mower and putting the u it up on jack stands.
The plates were worn out of the wear limits and would no longer engage.
The minimum spec for the clutch plate is .059 and the clutch disk is the same. Mine were at .054 to .056.

The Kubota place put in a clutch kit for about $600 plus labor. It is overpriced and has lots of things that did not need to be replaced. If I had to do it over again, I would order the clutch plates online for much less and I would do it myself. The only thing is it is a little tricky getting the clutch tangs lined up in the housing and you have to apply gasket compound very carefully around the plate, as there is not a gasket.

Thanks for the information, i too bought the clutch kit and the gasket compound and will be doing the install tomorrow.

The amount of work required for this job hasnt been too bad, im just worried that i will have to do it again in 100 hours.

I think the snowblower is really wreaking havoc on the PTO clutch...

Oh and BTW, i was able to remove the boss for the screen just by inserting a slightly smaller drill bit, putting it on an angle and pulling it out.

Ok, job is complete, PTO clutch has been replaced and functioning perfectly, good as new.

Now when it happens again, which im sure it will, i have a backup clutch (when i finish rebuilding the old one) and the knowledge to replace fairly quickly, without removing the entire rear end.

Thanks for your help all
