5 speed double clutch adjustment

First let me ask you pro's about this one thing. Why is there so much slop on the input shafts of these live PTO tranny's? Is that what makes some of them rattle? I am looking at two right now that have at least 1/8 inch in and out free play on both tranny and pto shaft. I have two that don't rattle and three that do, one of them profusely. Now to the clutch adjustment. Given the geometry of the throwout bearing yoke, it appears to me that the further forward the yoke moves that it loses travel as it is pressed toward the clutch. Would i be correct on that? Also pertaining to that movement, every double clutch I have seen has the screws threaded about halfway in. It seems to me if they were screwed further out that it would give more action with less pedal movement, although they might need locking nuts to make sure they don't come out of adjustment. Also on the locking nuts. Would there need to be an equal amount of nuts to keep it in balance? Any and all info appreciated. I was looking at the shafts down through the steering box hole and noticed how far away the finger screws were away from the throwout bearing before it ever contacted them. That's what got me started on this adjustment thing.

Transmission rattle at low idle is caused by end play of the cluster gear on it's shaft and, possibly, other gears internally.

This can only be properly corrected by complete transmission overhaul including thrust washers and, likely, bearings.

Increase the idle to 6/800 RPM and you most likely will no longer hear it.

The double clutch is adjusted in a jig out of the tractor. Do not mess with it!

I think that's what I'll do but what about the adjustment of the yoke travel changing pedal range?

I suspect the front retainer is worn you can put the washer in a press and bell it out some more... That's what I did...

Clutch pedal height is users chose release bearing to clutch fingers clearance is what you set... You need just enoufh clearance the release bearing dose not run all the time... I never set/check it at the clutch pedal itself I go to the through shaft pivot and check it there...

If you have a good clutch set up measure it out for later reference that's what I did... Bolt the clutch to the flywheel and go from there I made my own jig but probably forgot how to use it...

Can you just shim it up? Both of the ones I am looking at have about 1/16" in-out play.

Reverse idler gear will make them rattle too. Bushing worn in gear.

I would put that washer in a press and move on with life... I am sure I put it in a socket are a piece of pipe and fudged with it till I got a nice fit... That washer is harder than frothy ell best I remember no ware on the washer its debatable if a shim would live there...

I think it is pretty hard, I dont think it would last either. It might get too much thrust on it. I might try shaving that retainer also. It has a brand new gear and thrust washer on the reverse idler shaft Shawn.
