Hi,
my name is Paul, i'm from Switzerland and am currently rebuilding a Comet series C.
Can someone please help me by providing the dimensions of:
- MO22, RFM, part no. FT117, porous bronze bush > inner and outer Ø and length? And, does it have to be porous bronze?
- Burman gearbox, 71X, mainshaft washer > thickness? It was missing on my bike and i forgot to order a new one...
Thanks for your help,
Paul

FT 117 is 7/16" x 9/16" x 5/8" long porous bronze is best, because it is not otherwise lubricated, you can use lead- bronze, but it is more expensive. PR50/ 71X is 5/8" x 1,3/8" x .120" measured on an old part.
