clutch grinding??

[Ginormous]

And the winner is... inertia brake adjustment! I adjusted the inertia brake last night just a little, and the grinding noise stopped. Tonight I adjusted the clutch so it had more play, and the grinding noise came back. *arg* Then I adjusted the inertia brake again (adjusting the clutch threw off the inertia brake adjustment) and the grinding went away again. :thumbsup:

Thanks everybody for your help! Especially Winston who guessed right on the inertia brake. It's time to celebrate. :drink:

My guess is the Inertia brake linkage must be lightly applying the brake and slowing the rear end gears,etc. to allow a smooth power shift. Huh!! sounds like One Fancy setup there. :thumbsup:

o.k. I'll bite, if my powershift sifts firm, can I adjust to soften the response ?

Glad it was simple fix I had figured as much! :thumbsup:

I use a different terminology is all but talking about the same thing. As it was explained to me by a Yanmar person there is a release valve associated with the inertia brake that dumps pressure to the clutch packs to help shifting also.

I cant prove it either way my manual is pretty vague on exactly what does what. But it does appear there are 2 ports in the clutch shaft next to the brake assy one is dark and one isn't which usually means fluid or not. fwtw

From what I have been told or have personal experience with-no adjustment. A firm shift is a normal thing on these a soft shift would probably mean trouble jmo.

GOOD question? I sure would like to see a parts Dia. and see how the Inertia barke setup works. May want to upgrade mine to a Power Shift. I just so happen to know were a parts tractor is close by. Hah!!! Steve.

CarDoc, Carey
I am with you..
Its my understanding that firm is good, just wondered what other minds were thinking.
I love the powershift, thought it would be real nice if a simple adjustment made it a smoother transition.........

I remember seeing on a thread here with some pics by a guy in Poland who tore apart his Yanmar transmission. You could search and find them. I believe it was last year some time.

Here is what I have on the inertia brake on 336 and probably 3110,3220,3810 and so on all similar is my guess including the 2210 G has. Its black and white or I could tell you exactly what they do the ports that is.

IMHO - These are similar to an automotive AT but lack the torque converter which cushions some of an AT's shifting shock.

The clutch packs inside the Powershift are similar to a multi-disc motorcycle clutch, where noticeable slip after a shift means excessive wear.
