hi im a fresh member here. i just bought a 01 660. $400 with a REAL title.

crank snapped in half and split left hand or "middle" case. everything els looks good from outside. its only a small hairline crack.

but is it worth it to "flip" one of these? i have to do something with it. i REALLY dont think parting it out is an option, takes way to long dont suggest that.

reason i'm asking. full rebuild could cost up to 1grand. 1400. then selling it any less than 2500 would suck

has anyone flipped one. or sold one that was just rebuilt with recipts?

Hate to tell you this bubba, but you are gonna have a tough time selling an '01 for $2500 bucks. Also, doesn't matter what year cases you get for a 660, the oil filter is always on the outside.

Those allen bolts are from your one way starter clutch assembly. They sheared off and dropped to the bottom. Take your left case cover off and you will see what I'm talking about. That needs to be replaced too otherwise you will be pull-starting once you get everything else back together. Thread locker those new allen bolts.

ok thanks that makes sense. but i dont know where the clutch is on that? i never have worked on a starter clutch got any pics? all i see is straight gears from the starter motor, no clutch system

Left side of the motor, behind the flywheel. There is a 52 tooth gear back there that will be the most obvious way of being able to tell what you are looking at.

Parts 6 and 9 specifically are the 52 tooth and the one way. Part 10 is the allen head bolts that sheared off and which you found in the bottom of your motor. Get the replacement from L&A Designs. Very good, and better than OEM.

o ok! so is the clutch the thing that has those plastic retainers holding steel dowels in? inside the flywheel? cuz the 52tooth gear couldnt be a clutch by itselft right?

Hey it might sound lame But when WKR sent me back my old parts I dipped the valves and piston in a degreaser called Purple Power. I left them overnight in the solution, Next day all the carbon had come off No brushing or scrubbing Then I sold them on Ebay.
