How much crank play too much

Recommended Posts

10HorseMan
I have a engine in my shop out of a A-C CA 125CID. The crankshaft moves forward when you mash the clutch, and back when you let the clutch go. Someone who has rebuilt the engine did not put the thrust bearings in it. My grandfather built this engine and it Knawed grooves up the sleeves and spun a bearing in #4. It had lots of power. And I want to build it to go in a B A-C All inquires are appreciated. :)

If you can see the crank move with you eyeball it's got too much play. Too many moveing parts inside for things to have much play before stuff starts comeing loose. Better get someone to fix the crank and use the thrust bearings thise time. Hope it's not too far gone.
