End Play Adjustment

I have a '37 JD A. I am going to adjust the end play on the flywheel. I see the manual says .005 to .010. I should adjust this how? With the belt pulley empty and someone pushing on it towards the crankcase, and then I push the flywheel in to spec above? Or should the clutch driver be installed with the crank bolt?

Any other good words?

Thanks,

Robert
 
It's done with the clutch and belt pulley fully assembled. With the clutch adjusted correctly, engage the clutch and block the belt pulley all the way to the left. Set up a dial indicator so it touches the inside of the flywheel. As you move the clutch lever back and forth without disengaging the clutch note the readings on the dial indicator. Move the flywheel in or out until you have between .005 to .010 end play. Tighten the flywheel nuts and check the dial indicator again to make sure nothing changed when you tightened the nuts.
 
Clutch pulley has nothing to do with setting the endplay. The measurement is the clearance between the thrust bearing portion of the main bearing (#13) and
the cam gear surface (part # 17 ). By adjusting the flywheel this will allow the crank to move in and out to give you this measurement. The flywheel pushes
against spacer (part #2) which pushes against main bearing housing (part 21). By pushing and pulling on the flywheel after snugging it up you can read what
the clearance is with a dial indicator.

Hmmm...Pete's method is just about exactly what my 60 series Service Manual (SM-2008) specifies as the proper adjustment procedure. Should be the same for an A. Or am I (and Pete) missing something?
 
Your not. I was clarifying how the end play is determined. Your procedure will work just fine but it is not necessary to have the clutch even on the crank to set
the end play if you follow what I was saying in my post nor do you have to go through the trouble of blocking the clutch toward the tractor. Just did a G this
afternoon my way having assembled the clutch afterwards and following the books way of doing it, I double checked the end play and it stayed the same.
 
MSD,

You said "Clutch pulley has nothing to do with setting the endplay".

You're wrong about that. Clutch has to be engaged and the clutch handle needs to be moved back and forth to move the crankshaft and determine the amount of existing end play.

If you doubt what I'm telling you go look in any 2cyl service manual.

The op asked how to set the end play, not where the clearance is that provides the end play.
 
Here is a quick shade tree way; Do the clutch lever rocking procedure. I'd there is a clunk the end play is too loose. Bump flywheel in till there is no more clunk when the clutch lever is rocked. Not recommended but I have done it this way to get it done quick.
 
I don't move the handle back and for but pull and push on the flywheel. The end play is set between the thrust bearing and the cam gear like I showed in the parts list. You don't need any clutch parts on the crank to set the end play because that is where it is determined from. Moving the clutch lever is just another way of doing the same thing as pushing and pulling on the flywheel. The advantage to doing it my way is if you have a dial indicator set on the flywheel you can read it as you move the flywheel, you don't have to be moving from side to side to get it done. Just because the service manual says to do it that way doesn't mean there aren't better, easier ways sometimes.
 
MSD,

Being tall I can stand on the left side while jogging the clutch lever and watching the dial indicator.
I agree with you that there are other ways to do a job besides what the service manual says.
