Wheel loaders: CAT 906H, 907H (Gearbox Auxiliary Shaft)
Compatible Assemblies: 4W-3001 (Hydraulic Pump Drive Shaft Assembly), 5J-2345 (Gearbox Auxiliary Shaft Assembly)
Matching Parts: 626-0487 Bearing, Bearing Housing (12-3456), Locking Nut (8T-4123), Locking Washer (9X-3456)
Installation and Fitting Points: Clean the journal and bearing housing bore, ensuring no burrs or rust. Journal surface roughness Ra≤0.8μm, bearing housing bore Ra≤1.6μm.
For cold installation, use a sleeve to evenly tap the outer ring (for bearing housing installation) or inner ring (for shaft installation). Do not directly strike the steel balls and cage.
After installation, check for end face runout ≤0.03mm, radial runout ≤0.02mm, and smooth rotation without jamming or abnormal noise.
When using grease lubrication, fill the bearing cavity to 1/3-1/2. When using oil lubrication, ensure that the oil level submerges the center of the lowest steel ball.
