As my engine seems to have spent most of it's life scuba diving I'm finding that pretty much every bearing and bush needs to be replaced. Most of these are proving straight forward except the one in the picture below which is retained by a screw and collar (?). Does anyone know if this bush is available and if so what the part number is as I've searched the parts fiche and can't find any sign of either the bush or the retaining screw and collar:-

The screw looks like that as I had to drill it out using a reverse drill..

There is one bush listed with the crank cases 23 x 33 x 14 ? 92028-1521
Looks like it's main shaft bearing outer race behind clutch basket? Look at C on the parts diagram page B14 crankcase

don't know what it is, but the seize of it is mentionned, so shouldn't be too dificult to find out by measuring what's in your casesProfessor wrote:There is one bush listed with the crank cases 23 x 33 x 14 ? 92028-1521

On early models, that bush was just pressed/shrunk in (no retainer and screw), so it didn't have the machined shoulder. The early bush (if I remember correctly) is exactly the same as 92028-1521.
The later bush however is not the same (due to the machined shoulder), although 92028-1521 can be used to replace it if you don't use the retainer and screw.
I'm not sure of the changeover point between the early and late arrangements, but have found the early arrangement in a JDM B1 with frame number just below 003000.
Regards,
James

Re: Calling All Engine Experts - Help Needed to Identify Par
Thank you all for your responses - much appreciated!
Yes James P - this would explain why I can't find any evidence of the screw and retainer on the fiche. Because it simply wasn't there on earlier bikes.
Fortunately for me Bernie500 has knocked one out of the park again and found me a spare which has got the project moving again. Cheers Bernie - can't thank you enough!!

Dave; The screw, the retainer and even the bearing track/bush are not shown on any of the parts diagrams I've got. I presume this is because they were included as part of the gearbox end plate (in similar manner to crankshafts being sold only as complete assemblies). If you needed a new screw, retainer and/or bearing track/bush, I presume you'd have had to buy the whole assembly!DeadHammer wrote:...this would explain why I can't find any evidence of the screw and retainer on the fiche.
