This is a general overview of our process which may vary slightly on a few of the more obscure racks, but the process is about the same. We currently have 8 versions of these bushings that go into the different variations of these racks.
We rebuild your rack by disassembling, degreasing and performing a thorough inspection of all internal parts. Unlike many rebuilders we do not hone and reuse your existing outer bushings. We have made all new outer bushings that allow us to hold a tighter tolerance. The precision required to install these properly is why we do not sell the components used in the rebuild as a kit.
For the casting we perform a thorough cleaning followed by an application of a coating that will act as a protectant and help keep it looking nice. We do not remove any of the identification tags that are installed but will cover them to prevent damage during the rebuild.
The internals are inspected for pitting then cleaned and polished to reduce excess friction during operation. We then inspect gearing and replace the drag puck to bring your rack back to factory specification. We can also do custom specs if you like.
All external steel parts, including the yoke and access covers, are then plated and new gaskets are installed. While the service manual calls for a general-purpose grease, we use a white lithium grease. This was chosen because it is the best grease for metal on metal contact and it shows that there are no contaminants left inside the rack.
