The parts we replace most, and their typical symptoms
These four systems account for most of the requests we receive. Describe the symptom and we will pin down the part number with you.
Hydraulic pump and cylinder seals
Boom/arm motion slowing down, oil temperature rising early, oil leaking from cylinders. Seals blow under high pressure and pump flow drops over time.
Main pump, piston-and-block group, cylinder seal kits
Undercarriage
Chain elongation on rocky and mining sites, seized roller bearings, worn sprocket teeth. A slack track chain quickly consumes the other components too.
Track chain and shoes, bottom/top rollers, idler, sprocket
Fuel system and injectors
On machines running dirty or poor-quality diesel: clogged injectors, fuel-pump failure, power loss and smoky operation.
Injectors, fuel pump, fuel filters, turbocharger
Swing bearing and swing reducer
Play, noise and shudder while slewing; broken teeth at a later stage. Once detected it needs immediate replacement.
Swing bearing, swing reducer, swing motor
