7Y4222 Travel Motor Seal Kit for CAT 320CL and 322BL Excavators

Product Description
Heavy-Duty 7Y4222 Travel Motor Final Drive Seal Kit for Caterpillar CAT 320CL & 322BL Excavators
Restore relentless tracking power and stop fluid contamination in your heavy earthmoving equipment with Toparts' premium 7Y4222 travel motor seal kit. Specifically precision-engineered for the ultimate drive and travel motor groups utilized on Caterpillar CAT 320CL and 322BL hydraulic excavators, this overhaul service kit is built to maintain tight fluid containment during continuous high-torque maneuvers and muddy track immersion.
The Toparts Engineering Difference: Built to Survive Final Drive Torture
Excavator travel motors operate in harsh, high-friction undercarriage conditions. Submerged in abrasive slurry, rock dust, and mud while enduring high rotational speeds and directional counter-rotations, standard aftermarket seals quickly suffer from lip hardening or pressure blow-bys. At Toparts, we manufacture our 7Y4222 kits with structural material upgrades:
High-Velocity Rotary Elastomer Matrix: Our dynamic rod and shaft seals are molded from advanced FKM / P6000 PU compounds to maintain continuous sealing elasticity at operating temperatures exceeding 120°C without lip cracking or thermal degradation.
Abrasive Excluder Dust Scrapers: Features aggressive double-lip wipers that aggressively sweep away fine quartz sand, gravel crusts, and water films from the spinning shaft, preventing particle intrusion into the hydraulic reduction gears.
High-Pressure Fluid Containment: Precision-engineered step seals and buffer rings withstand continuous high system pressures and sudden pressure spikes caused by high-speed track braking or directional shifts.
Zero-Leaking Static O-Rings: Premium-grade NBR O-rings provide tight static sealing along the motor casing and valve block interfaces, completely preventing internal oil cross-contamination.
