Make your own CB500 Clutch Pushrod / Push Rod
matthewmosse:
So someone with a dead long type could in theory just modify it to short pushrod speck and add a ball bearing and short bit............
Bryanj:
Honda NEVER supplied a two piece pushrod but what happened in service was this:-
Original pushrod is alloy middle with steel end(s)
Chain not adjusted whips off front sprocket on overrun and hits pushrod breaking the end off.
Oil leak starts as pushrod now does not move linearly also operation deteriorates
Owner pulls out the broken piece, assumes cos he dont have a manual, that he has lost the centre ball bearing that a lot of britsh bikes had so puts one in (probably at the same time losing the ball in the operating mechanism)
Clutch operation gets even worse as the shorter piece wobbles even more
owner gets fed up, wont pay dealer prices to sort it properly and sells the bike
Further owners think this is the way its supposed to be and live with it
matthewmosse:
Ah, very enlightening, always wondered why the difference, Will use the one piece assemblies then. Must have been some very poorly adjusted chains out there as I've never had the chain jump off on these bikes and I consider myself to be about the worst offender for neglect of the bike. Come to think of it I've had a couple of engines that were really bad on the gearchanges so got shelved, I'll have to make a note of which ones have the 2 part pushrod as it may well save me a coupla rebuilds, just leaves me the mystery of the 500/4 engine that ate camchain tensioners to investigate..................
Bryanj:
Canchain tensioners got et when either
was not adjusted correctly
or
idiotic numbnuts put a screwdriver in the slot and forced the toothed wheel resulting in a crodged (technical term) tensioner
matthewmosse:
This bugger ate 2 tensioners in a year (10 000) miles, Adjusted them as per manual which is the same way as for all the other 500 /550 motors I've owned, I'm convinced the problem may lie deep within the bowels of the engine, say a crank sprockett thats cream crackered in some way but possibly a chain that was too short? Enigine was a USA inport and looked near mint but nothing to say some PO had been in there for somit..............
