description

This heavy-duty transmission gear is forged alloy steel with hardened tooth surface. It meshes with matching gear to transfer power under continuous shock load. Pitting, root crack, broken tooth and excessive wear will cause abnormal noise, power jitter and power interruption, and may damage gear set, bearings and seals.

Part No.:9W-9133
Type: Transmission gear
Material: Alloy steel, induction hardened tooth surface
Process: Forging & precision machining
Working Condition: Heavy load, low speed and impact for bulldozer transmission and final drive
Matching System: Transmission, final drive assembly

Application Scenarios

Fits Caterpillar D9L, D9R track-type tractor, for overhaul of transmission reduction and final drive planetary assembly.

FAQ 

Q：Can the gear with slight pitting be polished and reused?
A：Not recommended. Polishing removes hardened layer, pitting spreads quickly and tooth breakage risk rises.

Q：Can I replace only this gear and reuse the old mating gear?
A：Not recommended. Worn profile mismatch causes uneven load, loud noise and accelerated wear.

Q：What fault will excessive backlash bring?
A：Heavy impact and noise, cyclic shock load may lead to tooth root fatigue fracture.

Q：Will new gear eliminate axial play if the spline is worn?
A：No. Worn spline creates loose fit, inspect the shaft and replace it if needed.
