Designed to secure the axle bearing in place, this seat ensures that the rotational forces of the rear axle remain stable under extreme heavy-duty loads. Whether you are operating in mining environments or long-distance logistics, the integrity of the WG9970320035 is vital for preventing axle misalignment and premature gear wear.

Pre-Installation Inspection: Before fitting the new bearing seat, inspect the axle housing surface for any burrs or leftover gasket material. A clean surface is paramount for a flush fit.
Press-Fitting: The bearing should be pressed into the WG9970320035 seat using a hydraulic press. Avoid using a hammer directly on the seat to prevent hairline fractures.
Lubrication Tip: Apply a thin layer of heavy-duty lithium grease to the inner diameter of the seat to facilitate bearing installation and prevent "seizing" during future maintenance.
Torque Specs: Ensure all mounting bolts are tightened to Sinotruk’s recommended torque settings (refer to the HOWO Service Manual for specific NM values) to avoid stress concentration.
