Need piston part numbers

Thu Feb 05, 2009 5:40 pm » Post: #1 » Download Post

Please bare with me this is my first post !

Tried to order a MC 18 piston, pin, circlips, rings and small end bearing today for my MC16.

The vendor told me that there are 6 different pistons for the MC18 so they need engine numbers before they can order.

So as I dont have an MC 18 engine does anybody know the part numbers of the bits I need?

Any help would be greatly appreciated.

There are 3 different barrel types, A, B, and C. You need to know the barrel(s) you have (they may not necessarily be the same!) and then order the corresponding piston.

A barrel + B piston
B barrel + # piston (no mark)
C barrel + D piston

Don't ask why the middle piston isn't a "C"... no-one knows! Smile

Seeing as the barrels are in my shed, I'll have a look for a stamp
