Although motors are usually simple by design, rebuilding them is best left to experienced technicians with the proper testing equipment.

Paragon stocks most seal kits and repair parts for all the common brands of motors including Calzoni.

When it comes to motors, testing is most critical aspect of the repair. Unfortunately most hydraulic shops don’t load test because they do not have the right equipment. Our dynamometer was originally designed for radial piston motors and MHT motors back in the early 1990’s then later upgraded for the modern, more powerful Calzoni motors in 2009. When you have your motor repaired by Paragon, you can relax knowing we are doing the job right.
