Fixing your timing cover

[Holeshot]

Here's a thought:

Wet pressure testing of each set?? A dynoed oil pump, as it were...Dave

Man Dave you would be suprised how much volume is lost per .001 oversize of the cavity walls. We used to build gear pumps that held a .0002" all day long at 350 degrees

MC,

What do you charge to "rebuild" a customer's used timing cover/adaptor? Clean, nickle plate, hand fit gears, stainless plate, etc?

Thanks!

[jeepsr4ever]

I used to do it for $320 but I dont make any dough on it and its eats up my time. I can offer a New nickel coated cover with gears for $345 (used to be $320 before the price of materials went up)

[JMSII]

Does that include the adaptor as well?

[jeepsr4ever]

Sadly it doesnt

[Honcho]

Here are some covers which have been cleaned and bead blasted to give the nickle the best possible surface condition, notice the one in the middle, it still has the harmonic balance seal, that is my personal one, i got big plans for it so i left the seal in, normally i dont

I finally got the oil pump primer tool, thanx, yep thats who I am.
When glass bead blasting the covers, are you lightly hitting the mateing
surface where the oil pump adaptor and the timing cover touch?
Is there anyplace on the covers or the oil pump adaptors that should not be glass bead blasted?

[jeepsr4ever]

Avoid the mating surface there...that can be cleaned with scotchbrite

MC, those tolerances you have shown on this pump, is that applicable to a stock setup? I may end up getting a new pump from you, I am currently taking my pump appart to find out why I only have 30psi a 2500 rpm. But I don't know what tolerances are good and what tolerances are bad.

I see you also have plated adapter plates. You recomend a midplate with those adapter plates? Does a mid plate keep me from buying a whole new adapter if mine is wore?

Are those gears aluminum?

Bump

Shawn, MC was at the FSJ Invasion when you wrote this so he may not have seen it - so I'm bumping your question for ya.

I have the whole setup (nickle cover, pump, gears) but haven't seen it since I left it at the machine shop (AMC 360, 30 over, cross drilled crank, oil modded, balanced, etc...) but the gears are steel (and my motor is due back this week ). Aluminium changes dimentions too much under heat load and I have a feeling they would eat themseves in no time.
