Hey all,

So I replaced my oil pump yesterday all went surprisingly well until I went to install the timing belt tensioner. Is there a spacer that goes behind it or something? I don't remember seeing one when I removed it but, without one it sits too far against the belt cover and doesn't turn properly when tightened down. If there is one can someone describe it for me? I looked all over for what I thought it might be but never found anything.

Thanks,

not sure on early cars, but on my 86, there are no spacers behind any of the rollers/tensioners.

Nope, no spacer. It sits right atop of the oil pump. Perhaps your cover isn't properly seated. Two of the bolts that go into the oil pump hold on the cover.

Older pumps have a thicker casting where the timing belt tensioner stud goes through it and requires the proper shouldered nut tightned against the oil pump, then the tensioner goes over the stud against the nut. I believe this pump was pre automatic tensioner.

Later pumps have a thinner casting where the stud goes through and requires the nut tightned against the oil pump and then a spacer that is approx 1/4 inch thick placed on the stud and then the tensioner placed on the stud.

Compare your old pump with the new pump and measure the thickness difference where the stud goes through the pump. The difference is how wide the spacer needs to be.

Yea, that's it, I put an '87 oil pump on an '84 engine, oh crap. But cool there's a fix. Thanks again guys,
