Those gears look serviceable to you?

[SuperSix]

You need (5) 1/4-20 X 1" and (1) 1/4-20 X 1-1-1/2.
 

And of course, there's a trick. You'll noticed the long bolts you have are small headed bolts with a built in washer. A normal 1/4 bolt will have a head too big to actuate with a wrench or a socket.

or you could just get one of my pimp ass SS socket head cap screw timing cover kits and be done with it

Is the bolt length indicated the total length? Or just the threaded part to the bolt shoulder?

Either way, I'm pretty sure these are the pump repair bolts - the short ones are 1.459" overall, 1,245" from end to shoulder, and the long one is 1.713 overall, 1.493 to the shoulder.

I guess I could cut these - I doubt I will. I will probably get the Allen head SS ones from Alloy Boltz..

Bolts are measured from the tip of the threaded section to the area where the head and the shaft join together Mark.

I looked at the alloy boltz webpage. I don't think their kits come with the filter adapter bolts.

Mark, can you take a pic of the oil pump cover from the side that covers the gears...I don't have that on my site

The ony excepion being flat heads (countersunk) which are measured end to end (dunno why)

I got them at Home Depot this afternoon, of all places - .82c ea. Stainless Allen head.

I have one of the Alloy Boltz kits, and you are correct, it does not have the oil pump bolts.

I picked up some wet or dry 600grit to do some more work on the lower oil pump housing - is that going to be fine enough?

Like this?

New cover, old gears? With the amount of work you are doing, replacing the gears is a good insurance policy. I don't like the wear pattern on the edge of the gears.

Those gears are junk.
Get a new set and MAKE SURE you debur the tops and bottoms of the gear teeth.
I believe they're broached and do tend to have a burr due to the cutting process.

I just spent ~30 minutes with it, a can of WD-40, and 2 sheets of 600 wet/dry sandpaper - it looks much better now.

I realized that the bolts need washers - modified 2 washers for the pocket bolts - used regular ones on the other bolts. After putting it all together for a test fit - the gears wouldn't turn - looks like I will need to find a thicker gasket.

You guys are right. The standard Sealed power kit should work?

Odd, Jeg's is almost $5.00 cheaper than Rock Auto...

[Steve Wood]

looks right to me

[SuperSix]

The cooler adapter feels buttery smooth. Surface looks rough when zoomed in though.

[daveismissing]

Are there reasons you would want to replace that casting?
