Remanufactured Hydraulic Rods and Cylinders | Piston Pumps and Motors
1. Piston Pump and Motor Groups - With Cat® Remanufactured Piston Pumps and Motors, the difference is in the details. Cores are thoroughly cleaned and inspected. Port plates are inspected for wear or damage and reconditioned by lapping or replaced with new parts. New piston slippers are installed, and pistons are reconditioned or replaced. Worn barrel assemblies are reconditioned by grinding or replaced anew, and all piston bore bushings are replaced with new and machined to new specifications. Vane pump cartridges are assembled with the latest design features. Rotors, cams and vanes are reconditioned or replaced with new components. All pump and motor groups are filled with premium oil, adjusted and performance tested to new specifications.
2. Hydraulic Rod - All Reman Rods are straightened, ground, chrome plated and polished; or they are replaced (re-rodded), depending on the extent of wear or damage. All re-rods are induction hardened, improving resistance to nicks and dents to extend seal life. Most feature inertia-welded eyes for superior strength. All new bearings are installed and eyes replaced with Cat parts if needed.
3. Hydraulic Cylinder - All Reman Cylinders are re-honed or the tubes are replaced, bore skived and roller burnished, depending on the extent of wear or damage. All re-tubed cylinders are tested for weld integrity; all new bearings are installed; and flanges, caps and trunnions are replaced with Cat parts if needed.
