Oil pump O rings / cylinder head gasket seals
« on: October 13, 2010, 11:19:31 AM »
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

I’m rebuilding the pump on my 750K7 but cannot get the small seal as it’s been discontinued! I would be interested in the part number for Goldwing small seal that you mentioned that would do the job Ash.
