specs of the primary

Post by travelcrazy »

Hello!

After trying to machine the original sprocket down at my university workshop (what failed, the stuff is to hard for our equipment) I'm gonna buy a new one.

But what are the specs of the sprocket? I's there a standard thickness toothdistance and so on?

It must fit the yanmar axle (25 mm), were did you guys order the sprocket?

thanks!

It's 3/8" duplex. But why don't you just take the sprocket to a decent hardware store? I got mine at Laman. Are you sure about the 25 mm? Isn't it 1"?
