I looking for a set of /2 sidecar transmission gears -- the 1-2-3 cluster and the three mating loose gears (4th gear isn't necessary; they're the the same on both bikes. I could trade for a set of normal gears.

Sidecar Gears

Hi Maurice:

Good talking with you the other day, and thanks for giving me Mike's number. I called him, and he wants to sell the sidecar transmission complete for $1,000! I have several /2 gearboxes and only need the cluster gear. In any event, I couldn't afford or justify that expense.

Do you think he can really get such a high price for an admittedly rare box? Maybe I've lost touch with prices on the purist restoration market.

Regards, Fred

But The Gear Cluster

I agree, but the gear cluster you want IS the valuable thing about the sidecar transmission. I've seen them advertised for more than that. Yes, the correct stuff is often very expensive.

R60/2 Gearbox

OK, so I couldn't come up with good sidecar gears, so I assembled my gearbox with the old side car gears, in which 3rd gear on the cluster had become badly galled and pitted when its bearing had failed. I expected 3rd to be very noisy, but it was no more so than any of the gears had ever been!

BTW, I had built this box with very tall gearing -- a 1:1 input shaft gear (a spare 4th gear from the output shaft), replacing the original 1.5:1 gear (this required welding and reboring the case to move the cluster and accommodate the new gear). With this setup, the stock 1st gear feels more like 3rd, so the sidecar gears make it a nearly perfect wide-ratio box, and 4th gear is 2,000 rpm at 55 mph.
