Here is the number on my motor that I got to rebuild how do you find out what year it is for sure # SC36E - 2009217

Thanks so much guys I will do a search again to see if I mised something.

Dunno if there has ever been a way to decode it. Only thing I can think is that it's a 2002 based on the "E". SC36 is the model.

Thanks for the info I should look at the one in my bike which is a 1999 and see what the number is on it. Maybe we can get a couple of other guys to look at there bikes also. The reason I want to find out is they changed the cam chains around 2000 I think use to know will have to find out. so they will have different gears and so on.

Mine was a 2000. Serial number SC36E 2302149.

the question I have about timing chains is:
What is the effect of running a new chain on the worn drive gear on the crank?

That gear is not replaceable. Is it better to run the stretched chain on the worn gear?

Hawkrider

Is it really worn? Is there visible "shark tooth" shape to them? I'd think that most aging comes in the form of stretch of the chain, not actual wear. I mean the thing is bathed in filtered oil all its life. Should be no wear at all, I'd think.

My '03 has a 10/02 build date on the VIN plate and SC36E 6600XXX on the engine.

Maybe some guys with '98s and '99s can chime in so you can pin it down.

The problem is, as the chain stretches, the pitch increases (distance between pins). This causes interference and wear on the gear teeth. So the parts wear out together.

I know from bicycle drivetrains that if you put a new chain onto worn cogs, you can feel the buzz of the drivetrain from the interference.

It may be fine, if there is not too much wear. I just thought I'd raise the question. Don't really know the answer in this case.

Hawkrider

I really dunno either. I was just throwing some thoughts out there. The camchain is a Hy-vo type, right? I'm not sure how they wear or how quickly. Here's a little bit of quality reading for ya': http://chain-guide.com/applications/...oth-chain.html
