I have mine pulled out to check specs, and install the "white" spring in my new Melling pump. Now I need some expert advice (since I need this to be right the first time.

First of all, what specs should I check, and what is acceptable?

Second, how do I go about re-assembling it? How much torque on the pump plate, should I use loc-tite, do both surfaces need to be really clean?

I cant get any good answers on something this specific elsewhere.

Thanks,
James

 

Make sure it's clean number one. You should normally use a gear lube on the gears and tighten the 10mm or 8mm whatever they are down to 13 ft lbs. It's around that, i'd have to check the spec but there is one for that.

Check, and shoot for .0020", with a plus tolerance of .0005" clearance, for the gear end play.

 

What pump do you have?

 

Here is the procedure you are looking for:


Leave the stock spring in it on a stock engine, you dont need anything else, even on a modded engine
