thought i was all ready for chucking the rebuilt engine back in soon, after emptying honda and tyga and a couple of forum member spares bins i'm back with another one
was checking the oil pump tonight for the o rings etc and the crankcases



i was thinking they dont match and i remember when the cases were in bits that the small hole was an oil way on to the crank bearings,

just realised what it is, the engine is a 28sp engine, from the manual it looks like the pump also feeds oil directly onto the clutch end outer crank bearing, does the 21 not get oil directly onto the bearings? the pump must be differant on a 22 and 28 and ive got the std 22 pump, which effectively means that there has been an open hole to the crankcase and no direct oiling, no wonder the bearings were f####d. i'm a bit hacked off now

can someone confirm my logic, might be a good reminder to others that 21 and 28 engines are not totally compatable.

so looking for a 28 oil pump and orings,

cheers
brendan
