Is this a genuine clutch lifter push rod mod or what...
Trigger:
Oddjob has one he was going to post the spec on. Mine are in a few bits and can not be trusted.
simonster:
Cheers. I'm investing in a digital vernier tomorrow so will update with any change to the specs already given.
Trigger:
Found a rod today hidden in a tea chest but, it is 236mm x 8mm and the mushroom end is 7.45mm dia x 12.15 :-\ :-\ :-\
simonster:
Your measurements are close to mine at 7.85 x 235 mm and mushroom end 7.45 x20 mm. Each end is hardened steel with the rod between being alloy reduce down to sleeve into the steel ends. The section which has snapped is at the join point on the adjuster side just beyond the transmission side of the oil seal. I' m thinking this may be a deliberate design weakness point to allow the push rod to snap rather than bend and play havoc with the clutch action caused by chain lash. I may be way off with this suggestion, but it seems the only reason to mix alloy and steel strength on a disposable part, other than a weight saving feature perhaps, but not believing that idea!??
Bryanj:
The lighter rod was to save weight (don't we all need that!) as the 500 has a nasty habit of clutch slip and a lighter rod should, in theory, move quicker. Having said that I have somewhere a new Honda part that is a gold passivated steel item
