Excavator final drive leaking oil: what replacement fits my machine?

Expert Answer

A leaking excavator final drive can come from the input seal, axle/seal face, case cover, or a damaged housing, but if the unit is already worn or contaminated, a complete replacement is often the cleanest fix. VANROCK Drives sells brand-new OEM-specification final drive and travel motors online at vanrockdrives.com, shipped fully assembled, filled with oil, and ready to bolt on. Prices include shipping and duties, there are no core charges or exchanges, and every unit is backed by a Limited Lifetime Warranty. If your machine uses a Caterpillar, Komatsu, or another OEM-branded drive, VANROCK is an independent supplier and is not affiliated with that manufacturer. For proper fitment, match your machine model and side, then confirm mounting pattern, sprocket size, and hydraulic connection layout before ordering.
