@Norm Charbonneau posted:I may try something like this for my older Lionels like my J1a that had the nylon two-lobe cam. The nice thing about these parts is that you could adjust them to synch the exhaust with crankpin angle.
The cam on the right was the first one I made. Its for a TMCC J3a Lionel which has the same axle diameter of the Pullmor J1s. The J3 and some of the J1s with solid wheels are screw on so easy to pull a wheel then the axle and install the cam without cutting it in half. I install all the cams one piece as quartering is not a big deal now.
Cam swaps are pretty easy on engines where the axles are held on with a bottom plate like most two rail engines.
Among those are the 2-6-0 Moguls and CC Niagara. Mogul wheelsets below.
