PRECISION GRINDING

Pioneer Parts Rebuilding was founded on resurfacing Caterpillar transmission plates in addition to hydraulic repairs.

 

We still offer resurfacing and precision grinding services to this day, and continuously utilize this in our repairs for piston pumps, travel motors, valve banks, and more to ensure our repairs are of the highest quality.
 

We are precise to 0.0005" (0.0127mm). We can facilitate diameters up to 40" and heights up to 10".
