Hi Guys Just finished replacing the cam chain on the FZR. Old one was stretched by 5-6mm so explained why it was a bit noisy. I'm wondering what strategies others have used to peen the pin in situ. Having fed the chain through the engine while temporarily attached to the other (pretty straightforward) the chain is obviously in the engine when it was reconnected. I have a chain breaker which made removal and reassembly relatively straightforward, but the breaker wont do the peening as the depth on the anvil indent is too much meaning squeezing it pushes the pin out by a few mm. I thought about trying to softly tap with a hammer or something but it's proving tricky to hold the chain in place, put something solid behind the chain and give it enough force to mushroom it over. It's like I need three hands heh... missus won't put hers anywhere helpful while I have a hammer in one of my hands lol Maybe @GreyImport @Linkin @Grasshopper have some tips please? I know @Murdo is sure to think of something clever too Cheers
Yeh I don't have a emgo one... just a cheapie and it didn't work. So looking for an alternative strategy.
You will need somebody to hold a hammer/dolly behind the link and peen the pins with a flat ended punch and hammer.
So I've given it a good go, however, I can't see anything overly noticeable happening. I had obviously given it some impact as the link got a little tighter (loosened now) but it pretty much looks like all the other links. I wonder if I should worry much more about it. I can no longer push the pin through the chain with my pliers (I was doing this to test if the pin was still too loose) and I probably could have done it if I applied substantial force but decided not to go that far as it seems to be doing its job. Top end is all back together now and timed up... interesting how the timing is almost a perfect line up now when before the marks were a couple of mm off (although still timed correctly). Getting pretty curious to see what this does... it makes sense but I wonder if the difference will be noticeable.
If nothing else.....should be a little quieter. With the amount of stretch you had, the tensioner would have been working overtime, should be all good now
I hope so... I practised peening on the old chain with the punch and even with a couple hard whacks it didn't visibly seem to do anything so I'm relatively content with what I was able to do.
