How To Adjust Clutch Fingers

[Rudi]

Guys:

Just did a search on the topic of adjusting the clutch for a post over on the ATIS forum. That reminded me of this particular forum and thought that this would be useful to post here.

Hope it helps

Here is the original post...


K, here is what we did.

First go to page 32 in the TC-37A Parts Catalog.

In the diagram you will see parts numbered 2, 3 and 4.

Part # 4 is the fingers or the Release Lever. Part #3 is the lock nut and Part #2 is the adjusting screw.

(Oh two people are best, that way you don't have to crawl out from under the tractor too often )

Rotate the engine over until you see the adjusting screw and nut and have access with a 1/2" wrench. Turn counter clockwise to loosen. Once the nut is loosend, turn with a standard bit in a ratchet 1/2 turn clockwise. Then retighten the lock nut.

Rotate the engine and repeat above until all three are done.

You should notice that the grinding is gone or there is substantial improvement. If it has not gone completely away, repeat with a 1/4 turn clockwise on the adjusting screw.

This is what we did. Now, depending on your problem you may have to turn the adjusting screw counterclockwise, but you will see that almost immediately.

Now, guys correct me if I am wrong, but, by using Jethro's exposed clutch assembly, we figured this out and we also checked the measurement. The stated figure used for adjusting the clutch appears to be pretty darn good, because when we adjusted Jethro's fingers and measured the distance from the face to the finger tip, it was exactly 1-1/8" before adjustment and 1-1/4" after adjustment. We used this on Ellie and it worked perfectly.

Your tranny should shift smoothly and quietly after this adjustment.

Wow The things you can learn just from reading posts on this forum. As in my case, I did not understand, nor could I visualize what all this meant until the last couple of days. Eventually though, the information I have absorbed did prove useful and I now rather rudimentarily understand the workings of the clutch.

Oh, if in doubt about the usefulness of information - see signature line

Thanks Rudi.

Rudi:

Request clarification. We have an exposed clutch assembly. Disk is installed and the pressure plate bolted to the flywheel.

Where exactly is the 1 1/4 inch height for the fingers measured from? Is height measured from the rear face of the clutch disc?

This is where you measure from.

I knew that there was a pictoral answer to the question Eugene posed and that same question has been asked dozens of times. I finally found the thread in which Dave had posted a pic of where to measure when adjusting the fingers, so I copied it and merged it to this thread so that folks would not have to go looking.

After reviewing the latest thread with the question on where to measure, BD posted a great pic that is pretty useful. So with both pics in this thread now, there should be no more questions. A picture is much better than a detail explanation, so thanks to both Dave and BD for the pics
