Backfired, died

I was thinking, our pumps are external and need gaskets and that kind of sets them apart from internal pumps where a little leakage would not matter. Yea a new cover/pump would be in order, I was taught a long time ago always replace a suspect pump, and always replace it when you do a rebuild.

 

Look real close to the gear ends, any discoloring I would toss them, if all they have are a little burring dress them up (emory cloth and mineral spirits, then polished with crocus cloth) and they should be ok. Also look up into the housing, the gears were sandwiched so there might be bad wear up inside, this is just as bad as wear on the plate.

 

Hope the timing cover is ok! Yea, when I tried to look at the catalog it 404ed me, probably my browser, don't know for sure. Sounds like you have a plan.

Thanks, that's what I was talking about,

"This shim kit is made up of several different thickness
Mylar shims for ensuring proper oil pump gear end
clearance. Kit includes a standard .008” gasket plus 8 Mylar
gaskets in the following thickness’ .001, .0015, .002, .003,
.005, .0075, .010, and .0125. Fits all but Nailhead.
Part No.
TA 1704 fits all except nailhead ..................... $14.95"

 

Sparky remember the discussion we had on the timing cover differences when you sent me yours? I can't remember is your timing cover the one that has the 2 bolts on the ouside edges or not. If the one that I have fits, the oil pump is fine. You can have it for shipping after I heli-coil the 2 oil pan bolt holes. The rest of it is in fine shape but the threads on the bottom are ragged as it looks like they tore when the bolts were removed.
Brass shim should work well, aluminum will work fine also, soda cans are cheap, I have used a bunch of 7-up cans in my day for dirt bike head gaskets. Good scissors will cut brass or aluminum up to about .015".

(edit) forgot about mylar that works great also.

 

Sparky a little scoring on the aluminum is acceptable just make sure its not really deep and covers most of the gear surface.

 

How deep do those goroves look. In the picture they don't look more than .002-.003" deep. If there no deeper than say .005 it should be fine.

 

Sparky so long as they don't feel really really deep with you finger nail don't worry about it. The housing doesn't look bad at all on my LCD monitor, the bottom definately has grooves but they really don't look bad.
Are the grooves in the housing just a bunch of little fine grooves that are all about the same? The cover looks like you have 1 or 2 deeper grooves but like I said if they don't feel more than about .005" deep don't worry about it, just smooth the burrs off with some emery.

 

Yep that sounds good Sparky.

 

I agree with Mcruff, it looks ok on both sides, (as long as no groves were more than .005", and it is hard to measure the grooves) kind of like what you would see in a pump with high miles, but serviceable. I always err on the side of caution, if it is in question I have always swapped to new parts. as I said earlier the old guy that mentored me never took a short cut on an oil pump. As I said before if you decide to reuse what you have,and after you have proper indicated clearance, put a mechanical oil gauge on the engine so you don't question the pressure.
