Hello All,
I am rebuilding my redtop engine and have come to the oil pump.
would anyone who has a pump to hand or has some knowledge of them be able to measure the diameter of the front crank seal?
first image is of the chosen housing with the SBD supplied seal, and as you can see it doesn't fit. the housing has a diameter of ~40mm, where the SBD seal has a diameter of ~38mm.
second image shows the same housing with a seal i bought from eBay, with the part number '90322669'
SBD maintain that the seal they have supplied is correct, and even measured a pump whilst i was on the phone which measured at 38mm.
Can anyone help me work out what's going on?
