Olympia Maximatic threads

Olympia 49mm Head sizes

Group Gasket

Olympia lists their group head gasket as 48 X 58 X 7


Nut that holds burr carrier on is 13mm
Use 3 M4x40 machine screws in the burr carrier holes - finger tight then 1/2 turn each - round robbin to remove lower carrier. Gentle -if stuck get gear puller. One could tapper the end of the screw and grind a smooth and flat end to the screw - touch of grease..
There is a shear-pin that meshes with the bottom burr carrier - so they need to be aligned when re-assembling. A ink mark on the carrier and a second on the top of the shaft can help with alignment.
