description

Planet shaft is the core load-bearing pin of final drive planetary assembly. It mounts planet gears and needle bearings, bears continuous impact load, locates the rotation center of planet gears and distributes torque evenly. Journal scoring, wear, bending and blocked oil holes will lead to uneven planet gear wear, abnormal noise and excessive clearance, and may damage planet gears, sun gear and carrier.

FAQ 

Q：Can I keep using the planet shaft with minor scratches?
A：Not recommended. Scratches will abrade matched bearings,
increase clearance and cause gear noise or tooth breakage.

Q：Can bent planet shaft be straightened and reused?
A：Not recommended. Straightening changes internal stress, it may fracture under heavy impact load.

Q：Can I replace only the planet shaft without matched bearings?
A：Not recommended. Bearings are worn-in to old shaft, clearance mismatch causes premature bearing failure.

Q：What fault will blocked oil hole cause?
A：Lubrication loss leads to bearing overheating and seizure, further locking up the final drive.
