Crank only turns halfway

Engine, exhaust & cooling mods or problems. If it has to do with cooling, anything within the crank case, or exhaust, it goes here.

Crank only turns halfway

Postby Davidportersr » Wed May 03, 2017 8:16 am

Hey guys,

I'm working on my friends 93 en500. His flywheel magnets broke apart and tore up the innards of the case.
So I installed a new flywheel/magneto with the sealed magnets, new starter clutch, new stator and new starter relay.
I checked the crank before installation and it turned freely. I get it all back together, change the oil, and go to start it and it turns for a split second and clicks. After trying awhile to make it crank, I took the cover back off and removed everything from the crank. Turn it by hand and it turns in both directions halfway or maybe 1/3 turn and stops in either direction. Woodruff key is fine, and everything looks ok. Anyone else had this problem or know what direction I should take?

Sounds like you have magnet chunks deeper in the engine that are preventing it from turning over.
