Title: Cam chain replacement
Post by: Bargarabandit on June 12, 2021, 04:10:46 AM
Hi

Has anyone got any tips about replacing the cam chain without having to take the engine apart

Also are all timing chains endless? Can they be split and rejoined?

They are linkless, so you're gonna have to open up the cases. However - what happened to yours ?
If it broke in the motor, you'd have a lot more damage than just the chain. If you think its looking worn, it may not be a problem.

Cool.

This is a good writeop with pics of replacing the cam chain on the four cylinder GS500.

There are obvious differences between the four cylinder and two cylinder but the basic process is the same.
Hope that helps.

No need to split the cases. Take the cam cover off, then using a dremel or chain-breaker, break the old camchain, attach the new chain to the old one and carefully pull the new one through, then disconnect the old chain, and peen over a new pin into the new chain to join it up.
Professional M/C mechanics have been doing it this way for many years, quite safe as long as care is taken.

 Do I need a new link to peen or can I reuse the link that I split?

Doubt anyone in here has actually done it themselves but there is plenty on the net about the subject..........however, if you have to ask us this basic question you need to ask yourself.......is it within MY abilities.

It's the OLD chain you split to attach the new chain to, -As far as the new chain is concerned, depending on it's length - you might need to shorten it, as long as it's a nice clean break with no bending of the sideplate, no problem, you can do this on the bench so it's easy to do a clean break. Use a good chainbreaker, and dremel grind the end of the pin so it comes out easy. When you 'peen' the new pin, make sure you back it up and brace it with something as massive as poss. Take every care not to drop anything down into the crankcase!
