Need oil pump gasket for 48 DeSoto

[MarcDeSoto]

Does anyone just sell the oil pump gasket for a 48 DeSoto?  Can't seem to find one without having to buy a new oil pump.

Best Gasket shows a part number, not sure it it's available separately though.

I'm think of buying some gasket material and making my own gaskets.  And I see they make silicone instant gasket sealer that you just spread on without a paper gasket.

On my older Plymouth that uses spur gears in the oil pump, the gasket thickness sets the clearance between the block and the gears. Too thick a gasket and I will experience low oil pressure. Too thin and I guess there could be some rubbing.

 

Way back when I needed a gasket and did not have one available so I put a straight edge across the oil pump and used a feeler gauge to figure out what my clearances were going to be. If I recall correctly, I found that a brown paper shopping bag had the correct thickness and was easy to cut to shape.

 

You have a newer engine than mine but I suspect some of this still holds true. In particular I would be leery of using a silicone instant gasket material as I don’t see how you can control the final thickness of the material after the pump is installed and bolted tight.

Would not recommend the silicone in that application for many reasons.

NO silicone sealer....just use heavy gasket paper and carefully make one exactly to match the pump mounting surface.

Gasket paper used for this gasket is .012"-.015"

[MarcDeSoto]

Who sells heavy gasket paper?  I tried HF and O'Reilly's, but they don't carry it.

Tell a quality knowledgeable parts store to look up ...

Fel-Pro 3045

This is a sheet of 1/64" (.015") thick Felpro gasket paper...Felpro, Karropak and a few other companies make many different gasket materials and many thicknesses.

I find it very hard to believe this, my local store has many many options on gasket materials.....are you doing the looking online or did a store employee tell you that do not stock any gasket material....

[Dodgeb4ya]

It's a problem with parts stores getting counter help to find odscure parts at times.

yes, that's true.  If I tell an O'Reilly's clerk do they have any parts for a 48 DeSoto, he will say no.  But if I tell him, I have a 48 Chrysler Royal, all of a sudden, he has parts.  

[MarcDeSoto]

I forgot to say that the reason I want an oil pump gasket is because I've been told that you have prime the pump with oil or it won't start pumping.  And I'm assuming that if I remove the pump, I will need a new gasket.

There are two gasket with the oil pump.  the cover gasket and the pump to block gasket.  How do you plan to prime the oil pump?

[Kilgore47]

Years back I got a set of punches.  They are very helpful when making gaskets.

Here is the gasket number for the oil pump cover and base gasket taken from my McCord gasket catalog 1937-54

The numbers on the left are the MoPar part number the numbers on the right is the McCord Gasket number

 So the 46-54 number was the same gasket body gasket

 

Hope this get you in the right direction.  Again this is why i have collected the older cross reference catalogs.

As mentioned Olsen's will have that gasket and any others if and when needed.

The 1948 DeSoto oil pump cover uses a square cut rubber O-ring...don't mess with it unless necessary...some what hard to find. No paper gasket used on the cover plate just that square cut O-Ring.

[MarcDeSoto]

OK, today I went to O'reillys and asked for the Felpro 3045 kit.  It wasn't on the shelf, but the clerk found on in the back of the store.  I also bought those hole punches.  I would prime the pump by removing it and pouring some motor oil into it.  Then, turn the pinion gear before installing it again.

My dad used to pack the oil pump with petroleum jelly, prior to installing.

[LazyK]

pack all my oil pumps with white grease,prior to start up, and have never had a problem.

Reason I asked how Marc was going to prime the pump was that if you go the grease route you will need an end cover gasket/seal.
