description

This ductile iron housing is the main support of final drive assembly, holding planetary gears, bearings and seals. It bears heavy impact load during travel and maintains alignment of transmission parts. Crack, warped mating surface, stripped thread and damaged sealing face will lead to oil leakage, contamination, uneven bearing wear, gear noise and even final drive lock-up.

FAQ 

Q：Can housing with minor surface crack be welded and reused?
A：Not recommended. Alternating shock load causes re-cracking, new housing is preferred.

Q：Can I reuse old planetary gears and bearings with new housing?
A：Inspect wear and alignment carefully. Worn parts will fail quickly after reassembly.

Q：Can slightly warped mating surface be reused after grinding?
A：Light warping is repairable, excessive grinding changes clearance and leads to leakage and hot bearing.

Q：Can I tap larger thread for stripped bolt holes?
A：It weakens housing. Thread insert repair or new housing is better for heavy impact load.
