How many times should you be able to hand crank a REW?
Mines out of my car with the turbos on and LIM on and I can hand crank it for three turns of the flywheel but then i cant go any more unless i go the other way. My NA engine lets me go as long as I want.

 

When mine was on the stand after the rebuild it would go as long as you like. Makes a nice swoosh too !!

 

yeah I just pulled mine appart last night but before that mine let me go forever. I was using a surynge to inject some oil to make sure nothing was causing to much friction but i think thats more me being paranoid then actually something needed

 

You've got something stuck in there. Take it apart and find out what it is or you'll end up scoring up the housing or damaging the rotor. Ask me how I know.
