Oil Pump vs Pulley Tin

[Beacon]

I’ve installed an Empi #9207 oil pump with a screw-on filter. Unfortunately, the pump’s case is so thick that I can’t mount the tin that fits around the crank pulley. The case pushes the tin out so far that it rubs against the pulley. I’ve had to grind down the pump’s case (see arrow in photo) to get the tin to fit. It works, but I’ve never known this to be needed on other cars. Any ideas what I’m doing wrong?

You haven't done anything wrong. The problem is that style pump was made for off road cars, like sand rails that don't use the pulley tin.

Or put a notch in the tin, that little cut will not hinder keeping road air out and with the tin piece it will give something for the rear tin to mate with.

rework the tin.... bend,cut whatever you are good at.I didnt have to trim my pump when I ran one of those...long long ago...also those usualy have 35mm gears and small oil passages, you must run a thinner oil...like 5-20 or 10-20 or 5-30 max. other wize the drive tang and camshaft usualy get trashed from it taking somuch power to pump the oil through the tiny passages. I did however have to trim the case or back of the pumparm thingy as it was held away from teh case by some portion of the case where the pump has a relief cut any way...just not enough on all cases.

One thing that this type of oil filter / pump WILL DO, is to raise the temp of the engine oil especially when just driving around town. It's not as bad at freeway driving where there is turbulent air flow in the engine compartment, but it really shows itself in slow speed town driving. You have to remember, that this style of pump was designed as a kind of poor man's full flow filter / pump for off road vehicles, with open engine compartments. When it is in a sealed area, problems can arise. I have tested this (on more then one car), and seen an approximate change in oil temps in the 30 degree range.. The problem is that the filter is very close to the exhaust. To fix it you use the same basic product, but it can be used to different ways. The product is something similar to this:

Method 1, and the easiest is to just buy the smallest quantity that you can, and just wrap the filter can itself. Method #2 is to wrap the exhaust in the area of the filter / pump.

There is nothing wrong per say with this style of pump, in fact the first one I used was from Clause's Buggies, (way before they were CB). In fact all styles of full flow systems can suffer from this problem. Any time you get an oil holding device near the exhaust system, IT WILL pick up the radiant heat from the exhaust, and raise your oil temp. All of my type 1s have heat wrap on the exhaust when ever an oil line is close to the exhaust, and in every case, the in town oil temp has decreased..
