How do you adjust crankshaft endplay?
The one I have has about 3/8 in.

Thank you
KEV

Kev - After making your end play adjustment, it wouldn't be a bad idea to check the nuts after running for a short while. They often need to be retightened.

Kev, that 3/8" is way too much.. The spec is .005"-.010"..

To re-set the crankshaft end play start by loosening the flywheel pinch bolts [actually I usually completely remove them & so I can check for thread stretching [a very common problem if those bolts were EVER over tightened]� That flywheel on your tractor has migrated to give you 3/8� so check those bolts as they aren�t holding very good..

Then remove the clutch pulley cover & use a few blocks of wood & a small hydraulic jack [or use all wood blocks] between the R/H tire & crankshaft to force & hold the R/H center of the crankshaft [inside the pulley] ALL the way over to the left [flywheel side] of the tractor�

Then use a lead hammer or large hammer & block of hardwood to drive the flywheel all the way on the crankshaft tight..

Then remove the blocks of wood & jack [if used]..

Then use a small hammer or hammer & brass drift to lightly tap the center of the crankshaft back through the flywheel [SLIGHTLY] until you get about .005�-.010� of lateral end play when pushing & pulling on the flywheel.

If you have access to a dial indicator set that up between the flywheel rim & main case.. If you don�t have a dial indicator you can do it by feel.. .005�-.010� is just the SLIGHTEST lateral movement [almost none] with the flywheel making a very light thunking sound when pushing & pulling on the flywheel.. If you get a louder clunking sound it is too loose yet..

Any questions just post back..

Kev -
I use almost the same method that John T described, except I have a friend hold the flywheel, and use a block on the end on the crank nut on the pulley side. I then hit the block with a sledge tapping the crank into the flywheel. The block is at a bit of an angle due to the tire. (I have 36 inch tires.)

However this method did not work recently, due to replacing the cork seal in the oil slinger. (Mine was a 35 B...later ones are rubber.) The problem was the slinger was not seated far enough in, so I pulled the flywheel back off, and holding the crank shaft with a sledge on the nut, used a brass pin and tapped (rather soundly) the edge of the oil slinger to get it seated. Then the flywheel went all the way on.

I did not check the end play with feeler guages....it just felt right. You can see the pulley move laterally when engaging and disengaging the clutch when not running.

Kev, I adjust mine by loosening the flywheel bolts, then a guy over on the other pulley side holds a big sledge tight up against the big center bolt in the crank (drive disc) then I use an oak block and a hammer and take the flywheel in about as far as I can get it. The spec is around 0.010 to 0.015 and I take it to where you can feel practically no end play when you grab the flywheel, then tighten the flywheel bolts back down tight to torque, use her some and recheck the torque another time or two to be safe. If the threads are bad or stretched, use new flywheel bolts. If you have the flywheel off, dont forget about the flywheels lil inner tip going into the oil slingers open notch.

Thats how I adjust mine anyway, it will be interestign to hear other ways or opinions and see how they adjust theirs.

Good Luck n God Bless

John T
