Rebuild Process

All motor cores go into a multi step cleaning process to remove external contaminants. Once cleaned, the motors get moved to the work bench for disassembly one by one. We check the mount area near the lip seal for cracks due to contact. During this step, the main shaft will be removed so we can check for damaged threads to the main shaft and damage to the key way area. The internal area of the main shaft, where the drive link goes also gets checked for damaged teeth. The drive link gets the same visual inspection to check for excessive wear or for broken teeth.  Once the center gerotor group gets removed, worn roller bearings will be obvious. Both the main roller bearing and internal roller bearings get pressed out, leaving the internal thrust bearings and washers get checked for damage and wear. The rebuildable pieces get set aside and the rest go to the scrap bin. Good shafts and gerotor group bearings get sent in for hard chrome bringing them back to the specifications we use. Reassembly begins with all cleaned parts. The new main roller bearing is pressed in and the seal kit is installed. We use a Made in USA main roller shaft bearing and O.E Parker seal kits. The rotating gerotor group gets tightened up with the appropriate amount of re-chromed roller bearings. Each gerotor group varies on how many re-chromed rollers will be used depending on wear. After each motor is fully reassembled, they independently get ran on the test stand to check for functionality. Once passing, they get pressure tested at 2500 psi to check for leaks. Each completed unit then gets coated with professional grade semi gloss black spray paint and shipped out or delivered to the end user.
