Direct drum ?

[Lee Thompson]

My friend made a fixture to hold direct drum so he could TRUE them for me. Sent him some recently--he brought 1 back that has a smaller dia. where the sealing rings ride. Anyone run into this before. Obviously take a different center support. Thanks

I wasn't aware of different I.D.'s on direct drums for 200-4r's? Are you sure the drum is from a 200-4R and not a 200C? I'm not familliar with the 200C so I couldn't tell you if they are different. Maybe someone else can chime in.

Maybe a 200 3 speed drum? Does it also have the smaller ID front bushing?
