New water pump issue!! :-(

[Martin53Cranbrook]

so i just got my water pump i ordered from Rockauto.com and it only came with one new bolt, i can't seem to find the other two that came off when i took the old pump off what size/type of bolts to i need

[bamfordsgarage]

Maybe one more same as the one you have?

[Martin53Cranbrook]

well the one that came with the pump as a long shoulder on it, i just worried about getting bolts to long or two short for the other two holes, i guess i will just hit a harware store tomorrow and try to match them up

[flatheadtim]

If it the same as a p15 there are two long bolts one short all the same thread pitch.

[Martin53Cranbrook]

looks likes mine needs one long and two short

[bamfordsgarage]

Silly me. I was thinking fuel pump which has two identical bolts.

Anyway it shouldn't be hard to figure out what you need. With the pump off the block you can run the one bolt you have into the holes to find how deep the threads go into the block, then make sure the bolts you choose don't go quite that far.

When you put on your water pump make sure you use anti-seize on the bolts. It not only makes it much easier to take them out at a later date, it also acts as a great sealant as at least one bolt, maybe two, goes into the water jacket.

I'd give you the bolt numbers if the '38-'48 parts book had them, but I don't see them there. In '33 they used studs instead of bolts:

2 each "long stud" part 112572 which is a 3⁄8-16-24x1 5⁄8 Plain steel stud

1 each "short stud" part 103196 which is a 3⁄8-16-24x1 Plain steel stud

So I guess some 3/8-16 bolds with a quarter inch or so less length than the studs would match up pretty well.

awesome, exactly what i needed to know, thank you

And the reason the new pump comes with one bolt is because it changes up the bolt requirement and uses 2 long ones and 1 short one. I personally chucked their included bolt and got my own grade 8s.

a rocket scientist would have: measured the body of the pump for length, allowed for the lock washer, measured the depth of the threaded hole, subtract the thickness of the lock washer twice and bought bolt of proper length..minimum grade of 5 now of course if you are clueless to diameter and TPI you could still be in a heap of trouble...

whatever happened to bag and tag hardware...? it sounds childish at times i agree..but if your car is apart for a bit of time..you would be surprised at the small details you were sure you would remember..had somehow escaped recall at the present..

[Young Ed]

Don't forget to include the thickness of the tension arm for the belt. I did and cut my bolt too short and had to buy another

Probably should use bolts if you want to be able to take off water pump as an assembly with fan otherwise you will hit the radiator with stud type and have to remove radiator.

yes Ed, I hould have mentioned any other pheriphal device that is secure with the bolt..just pointing out its is not difficult to select the proper length bolt..I will stand in the corner now for at least 12 minutes for that slip...

[Young Ed]

Oh and dont use one thats too long and sticks into the water jacket. You'll have issues when you go to remove it again. Thats what happened to the last one I did.

no cheating Tim a full 12 minutes Wow you must have A.D.D. LOL

I figured it to be a math issue (is that rocket science??) he said he had two bolts and I know one had to be long cause he said he had a short one soooo the one needed should match the other long one Tim Adams is a funny guy!

Don..TPI (terribily placed information) dang...back to the corner again this morning...!
