Master link timing chains
 

I'm at the point of fitting my new chains. The old ones appeared OK but the low cost of new ones tempted me into replacing them whilst the motor is in bits. I purchased the master link ones as I've not split the case but there are no instructions :rolleyes: I've done a search on here but can't really find anything. Are there any things to be aware of? Which way do should the open end of the link point? Should I secure the circlips with any particular compound (Loctite or something?) The chains are from the same manufacturer as the OE ones.
Thanks

Closed end goes in the direction of chain travel, make sure the clips are seated, make sure the sprockets are aligned & parallel, check chain ramps(5 black 911.105.222.06 and 1 brown 911.105.222.05 on the bottom right), check sprockets for wear(hooked appearance of the teeth)

how do you "break" the old chain?

There's a little tool called a chain breaker, which pops the rivet out

ah, just like a motorcycle chain tool. thanks bill.

Well, I've done it now and simply used an angle grinder on each side of one of the pins and it punched straight out. I connected the new chain to the old one to wind it round. Very straightforward really, just hope those circlips hold out!

Make sure you don't get grit in your engine when grinding!

I actually wrapped the whole engine in polythene, and cut a small slit in each side to pull the chain through while grinding. It only needed a couple of seconds on each side, to my surprise, but worked a treat!
