I have never become totally familiar with how to adjust for crank end play. I have had the flywheel and the clutch off on my A. I have put the clutch back on, but I know that I have to worry about end play having to do with where my flywheel goes back on. Is end play the amount that the crankshaft moves back and fourth in the case? Where do I measure from? Should I be able to grab the flywheel and move the whole assembly back and fourth about 1/16 to 1/8 of an inch? I&T manuals do not help...I want to get this running this week...thanks...AC

OK, I have that. Thank you all. I have the flywheel on where I can grab it and feel it move a very light dunk....dunk, but really can't see it move in and out. I did force the clutch side to the left so I could slide the flywheel on all the way. Now about this oil slinger...I gather that it is on the flywheel side. is it on the inside or the outside? The only thing I knew to line up was the button on the crankspline that went in to the flywheel. I know I have the flywheel lined up on the right spot. I just would like a little info on this oil slinger deal. Does it put oil in the left mains? Thanks...Andrew

The advise everyone has given you is right on the mark. One little trick I have used to help get the flywheel all the way on without a helper is to put a bottle jack between the right tire and the clutch end of the crankshaft. Be gentle and that will push the crank all the way to the left so you can slide the flywheel all the way on. Again be sure the drive lug is lined up with the notch in the oil slinger(be sure to center the L.H. main bearing cover on the slinger) and you're home free. Good luck,
Paul

AC, you're on the right track. The crankshaft end play is the amount the crankshaft can be moved latterly. The spec is .005"-.010". That is measured with the flywheel on & snug.
~If you have a dial indicator that would be measured from the crankcase to the flywheel or any part on the crankshaft [I usually measure from the crankcase to the rim of the flywheel]. It should be set at the tightest point in the flywheel rotation [if there is a tight spot].
~If you don't have a dial indicator you can set it to about as tight as you can & still feel a little lateral movement. ~When set correctly you will get a light thunk & not a heavier clunk when moving the flywheel in & out.
~To set the end play have someone hold something heavy against the crankshaft inside the pulley then drive the flywheel on about as tight as you can, then use a hammer & block of wood or piece of brass & give the center of the crankshaft [in the center of the flywheel] a little swat & see if the end play is about correct [repeat as needed].. Then tighten the flywheel & recheck....

Hey there AC, yes, after the clutch is on good and tight, then you place the flywheel back on basically about as far in toward the case as it will go, and the 0.005 to 0.010 end play spec (NOT 1/8 inch) is how tight the flywheel is up against where it fits against that D shaped seal/bearing cover. Dont forget its lil tip has to go in side the open notch in the oil slinger which is just inside that D shaped housing. When on right, if you grab a hold of the flywheel, you should just barely be able to detect a slight in/out free play/movement. Of course, BOTH the flywheel and clutch disk have to be installed back in time on the correct splines, or else you will get a big time vibration. Theres usualy v shaped marks and punch dots etc to get em on their right splines. We have 1 guy hold a sledge up against the clutch disk center bolt while a guy on the opposite side drives the flywheel in to her milk. If those 2 big flywheel bolts show any excess wear or thread stretching, I use new grade 8 bolts and nuts. Thats about the extent of my knowkedge on this subject, Im more experienced and traiend in electricity, so if Clooney or someone else tells you different than this, you might wanna take their advice.

Good Luck n God Bless the USA
