I don't know about aluminum as a material for the center roller. The metal is soft and the cam chain will chip away at it causing these chips to fall into the oil and get trapped in the roller cages of the crankshaft. Ultimately causing excessive wear in the crankshaft roller cages and destroying the crank shaft. I looked at making them out of stainless but thought the price high.

Do you have the part numbers on these and the web site/phone number for the Auto-spot where these came from?

I had to purchase thru a broker in order to get them. Auto-Spot wouldn't deal directly with someone out side of Japan.

> Hello,

This site is fantastic. Not only for timing items. What did you do exactly to buy on this site ? What do you call a broker ? Sorry for my poor english.
Thank you a lot : Pierre
