Description
See how a Bobcat equipment specialist tears down and inspects the hydraulic pump on a Bobcat Steiner 430 Articulated Tractor. Follow along as he provides step-by-step instructions on how to gently remove the gears for checking and how to identify wear and tear on the pistons as he demonstrates what a good piston slipper should look like. You’ll also learn how to review the bearings and seals and inspect both for damage and wear, with additional guidance on how to identify when internal components should be replaced. After a thorough cleaning with WD-40, the tutorial wraps up with instructions on reinstalling the pump. This includes guidance on using the inline pressure tool to ensure the system is free of contamination before use.
Always obey warnings and instructions in the Operation & Maintenance manual when operating Bobcat machines or performing maintenance work.
