1936 John deere Model B

[Frank Vantacich]

How does one adjust the crank shaft end play on an unstyled Model B serial 21774. Sliding the flywheel in and out has no effect, like on the newer serial numbered B's, reason being the flywheel is limited by the oil slinger which is fixed on the crank shaft. I currently have .050 and when I move the flywheel in and out it causes the hand clutch lever to bounce.

Thank you for your help

"the flywheel is limited by the oil slinger which is fixed on the crank shaft"

I don't recall the oil slinger being "fixed on the crank shaft". Is yours stuck in place?

Look in the archives. This topic has been covered numerous times with some good advice. Frank

Frank, I have looked in the archives but have only found posts regarding the styled B's but I will check again. I think Bob may have the answer though.

I will remove the slinger cover since that makes a whole lot of sense to be the root of the problem, the slinger is stuck on the crank shaft.

I just wanted to make sure that the end play was not adjusted from the belt pulley side.

Thank you for the help, I will repost with my findings.

You will need to block the clutch pulley to the left to set your end-play.

bob, you hit the nail on the head, the slinger is stuck. I will try to remove it in the morning as opposed to beating on it to move it in. I would think it should slide freely in and out so .005 can be achieved.

You are aware there's a cork or rubber seal ring inside it, right?

Yes I am and this is what is preventing the slinger from going in further on the crankshaft. There is a corresponding spline high spot on the cork gasket, the groves on the crankshaft only go so far, once they end this is where to slinger/cork gasket gets hung up. I am sure if I knocked it hard enough it would either compress or break off these high spots but I think I will file them off.

Thanks for the tip bob
