5K3501 Upper Bearing Cap 5K-3501 OEM Hardened Aftermarket Caterpillar 980M 982M Wheel Loader 16M Motor Grader

Product details

High-density spheroidal ductile iron one-piece casting + stress relief pact uniform metallurgical structure without sand holes, shrinkage cavities and hidden microcracks. After annealing treatment, it has excellent impact toughness, compressive resistance and stable thermal expansion coefficient; no flange deformation, bolt hole elongation or cracking under long-term heavy-load swing and cold-hot alternation.

Black oxide anti-rust passivation + full multi-stage factory inspection.Whole surface anti-corrosion treatment, resistant to lubricating grease, muddy water and mine dust; 100% dimensional detection, flatness test, static load compression fatigue test and hydraulic sealing leakage test before delivery, ISO9001 certified production, fully compliant with CAT OEM drawing standards.

Separable independent replacement design to lower fleet maintenance cost.Upper and lower caps can be replaced separately when deformed or worn, no need to disassemble the whole large articulated frame assembly, greatly shorten disassembly overhaul working hours and reduce long-term maintenance expenditure.

Bear frame upward axial load to buffer swing torsion impact.Thickened ductile iron main body absorbs instantaneous lateral impact generated by grader blade cutting, full-load material stacking and uneven ground driving, reduce fatigue abrasion of pivot pin, thrust washer and bearing, extend overall overhaul cycle of articulated frame system.

High-frequency matched safety maintenance part with stable market demand.Hinge grease leakage, frame loose shaking and heavy steering are common high-frequency faults of CAT 982M large loaders and 16M motor graders; this upper bearing cap must be replaced together with 5K3502 lower cap during hinge disassembly overhaul, huge aftermarket sales volume and stable repurchase rate.
