MAG170VP Final Drive Assy & Travel Motor Assy for Kobelco SK200-8/9, SK250-8/10, SK260-8

The MAG170VP final drive assy and travel motor assy is a high-precision replacement solution engineered for Kobelco excavator models such as SK200-8, SK200-9, SK250-8, SK250-10 and SK260-8. This assembly (including part numbers LQ15V00031F5, LQ15V00051F5, LQ15V00081F2 and LQ15V00020F1) pairs a robust axial-piston hydraulic motor with a hardened planetary gearbox to deliver the torque, travel speed and sealing durability required on construction sites.

How to identify the correct final drive for my Kobelco SK200-8 / SK250-10?

What model numbers and part codes indicate compatibility?

Confirm compatibility by matching the excavator model (SK200-8, SK200-9, SK250-8, SK250-10, SK260-8) with part numbers LQ15V00031F5, LQ15V00051F5, LQ15V00081F2 or LQ15V00020F1; these correspond to MAG170VP final drive assemblies designed for those frames and undercarriage gear ratios. Cross-reference the serial plate on your carrier, the travel motor flange pattern, and the axle spline count to ensure exact fitment before ordering.

How to read a final drive serial or casting number during inspection?

Locate engraved or stamped identifiers on the gearbox housing and motor flange and compare them to OEM diagrams; the final drive housing typically lists the MAG170VP designation or the substitute part code. Photographic documentation and an onsite dimension check (mounting bolt circle, input shaft diameter) remove ambiguity and speed approval for procurement and warranty validation.

Why do MAG170VP travel motors fail and how can I prevent it?

What causes premature wear in final drives and travel motors?

Primary failure drivers are hydraulic contamination, thermal cycling, and external shock loads; contaminated hydraulic oil accelerates bearing and gear wear inside the MAG170VP final drive assy. Implementing fluid cleanliness targets (ISO 4406 codes), proper filtration and monitoring reduces particle-induced fatigue and extends service life.

How to maintain the final drive to extend operational life?

Regular oil sampling, filter replacement, and torque-checking of wheel and input bolts are essential preventative steps; most heavy-duty fleets schedule oil checks every 250–500 operating hours depending on duty cycle. Use manufacturer-recommended hydraulic oil viscosity and change intervals, and immediately address seal leaks to prevent water ingress and abrasion.

How to install and replace a MAG170VP final drive assy safely and correctly?

What pre-installation checks are necessary?

Before installation, verify that the excavator swing and travel hydraulic lines are depressurized, the new MAG170VP assembly matches mounting dimensions, and mating surfaces are clean and free of burrs. Inspect hydraulic hoses, flange gaskets and O-rings and replace any components showing wear to prevent immediate post-install failures.

How to follow torque and hydraulic specifications during installation?

Apply the OEM-recommended torque for mounting bolts and ensure hydraulic connections use rated pressure hoses and fittings; incorrect torque causes misalignment and leaks. Reference Kobelco factory manuals or equivalent technical bulletins for exact bolt torques and hose pressure ratings to ensure safe commissioning.

How to choose between OEM and aftermarket final drive assemblies for MAG170VP?

What performance trade-offs exist between OEM and high-quality aftermarket units?

OEM units typically match original specifications and warranty terms, while high-quality aftermarket MAG170VP final drive assy options can offer cost savings and tailored upgrades (improved seals, hardened gearsets). Evaluate vendor traceability, machining tolerances, and bearing brands—these factors determine long-term reliability more than initial price alone.

How to verify quality certifications and supplier credibility?

Request material certificates, ISO 9001 quality system evidence and test reports for each batch; suppliers who publish third-party testing and a clear warranty policy reduce supply-chain risk. SPARKLING MACHINERY applies strict quality control aligned with industry standards—refer to ISO quality guidance here: ISO 9001 quality management overview.
