Man Vince you better watch out I think I can open a shop to compete with you with all those detail photos...
No I wouldnt even attempt to open mine. I was nervous when I installed the shift kit...
Nice work some day I will own one of these

Sorry for the delay. Here are a few shots of what we do to resurface our pumps. We feel that this is a good practice to ensure that the pump surface is true and not warped. If it is not perfectly flat cross leaks can cause failures. Also if the pump pocket is worn a loss of pressure happens. Here is a photo of what most well worn used pumps look like before they are machined.
We have a fixture that we use here in house on our lathe to resurface our pumps. Here is a photo of the fixture set up for machining the stator side of the pump.
Here is a photo of the stator side of the pump set up in our fixture before machining.
Here are a couple photo's of the machining process.
Here is the finished product.
Here is the fixture set up for machining the pump body.
Here is a photo of a finished pump body.
The next step is to measure the pump pocket. This is very important and very precise. You would be surprised to measure a factory pump body and see how far they are off. I have found that they can be out of spec .001-.003 when measuring in different places in the same pump. Which in my opinion is a lot when building a performance unit.
Here is a photo of both halves machined and all of the pieces that we install. As you can see a lot of work goes into these pumps along with many new parts.
Enjoy the new pictures. I will start working on some more when I have time. Vince

Man, that sure is shiny!
Seriously, do ya'll machine pumps for customers looking to get an existing pump machined? Just curious. If so, got a price set for that type of service?

Thanks for the post Frank. I started this thread to show you guy's how we do it and to educate some as well. As for parts we are currently not selling parts online. The reason is for the two of us it is to much to handle. Between tech calls, taking orders, packing boxes, and scheduling shipping it absorbs a lot of our time. Our main focus needs to be on building transmissions and until we can find the right individual to run the store, it has been put on hold. Vince
