Wheels barely spin - UPDATE fixed front but not rear
thanks guys for all the input. while i'm new to this site, i've been a member with other boards and this is one of the best. no smart asses and good info. i belonged to the ducati index (748 & 900SP) before and that site was really bad and is now closed.
i went through both wheels after work today, couldn't wait, impetuous me.
starting w/the front, i took off the wheels, removed the bearing dust shields and used a vaneer caliper to measure the depth of both bearings. both bearings were seated evenly. the bearings turned nicely. i reassembled everything, removed excess grease on the spacers (which were in the correct position) and wiped the axle free of grease. sprayed some wd-40 on the axle and put it all together. guess what? yep, the wheel spun alot better and i'm pleased. maybe too much grease on the spacers and axle, who knows?
now the rear. did the same, bearings were seated evenly, spacers in their proper place and reassembled w/o the chain, as some poster mentioned. wheel spun really nice and long. BUT WHEN I PUT ON THE CHAIN, MAJOR PROBLEMS!
i got about 40-42 mm of slack in the chain and the adjusters are even on both sides. the wheel barely turns! the chain feels and sounds likes its grinding big time. the chain and sprockets are in good shape with 6200 miles on them. (before i removed the wheels to powdercoat, the wheel spun well with the same chain and sprockets.) i wiped the chain & chain guides & sprayed some wd-40 on the chain & guides to clean them and hopefully add some "sliperyness" to these items. the wheel turned slightly better but not by much.
if the chain has proper slack and is relatively even (no i didn't use the string alignment trick yet), what gives? why the resistance and grinding? i read in the haynes manual that the chain protector/guard at the end on the swingarm has proper wear arrows, which i didn't check yet, but the wheel used to spin just a few weeks ago b/4 the powdercoating. the driven sprocket is just along for the ride, so the driver must be the bad guy(?) man it feels as if the motor seized and it's affecting the driver sprocket. but the motor is not seized, as i rode it yesterday and yes, the bike is in neutral. (btw, the rubber cush drives are in good shape.)
as always, i'd appreciate any sound advice and input. going crazy here, this is not all that complicated!!
