Hi,
I am sourcing 'O' rings to rebuild two Oil pumps I have. Are the originals Viton or Nitrile? If Nitrile are they 70 Shore A hardness?
( I am getting the small oil seal from David Silvers (the GoldWing type - Thanks for the info Bryan !!) but the 15x2 AND 46 X 2 'O' rings are really expensive from Honda
Also I think the o rings to use a later head gasket on a non-knock pin K0 sandcast head are 14 ID x 1.5mm thick (Viton) Can anyone confirm this please? Would a 'quad' ring be better, as I gather the unobtainium ones in the Honda bulletin were square section
Cheers !!! Ash
