CB 500 resurrection
gary123:
Limited progress but various pieces of engine have gone to Graham and the cases have been sent for a dip.
I have plastigauged the big end shells and they all came in at between 1.8 and 2.2 thou so I think that's ok. [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Not much progress since Ive been put on gardening duty, but did get a chance to go through the internals.
The needle bearing on the layshaft has one roller missing which may explain the damage to the inside of the upper case. cant imagine how it got free though.
Luckily I have a spare and to my untrained eye the other bearings all feel and look good.
Also had a trial fit of seat and tank, I dont think its the original/correct seat. [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Looking good Gary 8)

Seat cover isn't original. Need a pic of the seat pan to see if it's on the right base.
500 didn't get the disc guard, the 550 did. You can leave it on though as most people wouldn't know that.
The countershaft is out of a 550 not a 500. Unless you've nicked the needle roller bearing off the 550 as that's a small oil pump on the end.
Check how many teeth the primary drive gear has got. They differ between the 500 and 550 as the clutch basket changed. 500 has 24 and 550 has 26 IIRC.
Change the damper rubbers in the primary drive hub, sure we've already told you that.
