Hi,

Can anyone help?

I have overhauled my mechanical oil pump from a non working black lump of sludge and cr@p to a nice clean free spinning and properly gapped pump.

The only thing i am not sure on is how tight to do up the bottom plate. Haynes says "oil pump Torque = 15-25 Ft Lb" which i assume is the pump to block. at 20 Nm (15 FtLb) i can barely spin the pump meaning its compressing the O-Ring too much (IMHO).

Cheers for any advise or values.
