My 327 rebuild is coming along and now I am focusing my attention on parts that go on the engine. Water Pump, distributor, carb, etc. I have 2 original dated water pumps, but they both need a rebuild.

I contacted Arthur Gould in NY, but strangeness in their website turned me off a little (the shop is just in a house garage). ChevyCool is another (just a random garage door in a AZ mall), a member here had his done there.

I have a press and tried this years ago with Zip Corvette parts, but the shaft was for a short pump, 69s have the long pump. So that did not work.

I figure the shop cost is $100 to $120, shipping has got to be high $35-$50 each way. The total for one pump would be in the $200 range.

But I found this kit on Ebay for $75 with free ship: 1969 Chevrolet Camaro Z28 302 5.0L V8 New water pump rebuild Kit 3927170 3953692 | eBay seller has good feedback and seem to be a rebuilder/parts store in OR.

Looks like the correct long water pump and I need a new impeller anyways. I have the GM Service manual, with the rebuilding instructions. I am thinking about giving it a go.

Has anyone else tried rebuilding their water pump at home? thx

Did a few in the late 70s. It’s best to have proper tools and equipment so…..
Here a quick look

Bulk rate USPS Priority box is $22 and should accommodate the pump. Go to the Post office and bring a box home-test fit.

I decided to give it a try, since I found all my press tools I made. Instructions seem simple enough, just have to prep the pump body well. My kit(s) order will be shipped soon.

Before you disassembly the pump, determine the existing dimension from the mounting surface of the pump to the hub where your sheave (pulley) mounts. You will need to put it back in the same location (dimension) to assure you are not changing belt alignment.

I have four long pumps, they are all at 7". Plus I have the engine on a stand, so I will assemble pulleys and pump to dial in the belt alignment perfectly during the rebuild process. thx
