description

This cluster gear shaft is a stationary spindle inside transmission housing. The cluster gear rotates on bearings fitted to this shaft. It distributes input torque to speed gears and controls power transmission direction, serving as key positioning component for loader transmission.

It is made of quenched and tempered alloy steel. The running surface is induction hardened for crush resistance and fatigue resistance under alternating impact loads from gear meshing. Internal oil passages connect to transmission oil gallery to feed lubricant to gear bearings and prevent thermal seizure.

It fits transmission overhaul of Caterpillar 5130B loader. Precise 75 mm outer diameter controls bearing running clearance. Shaft shoulder, mounting flange and threaded holes are machined to OEM standard for stable positioning and reliable interchangeability.

Product Advantages

1. Quenched alloy steel base with hardened surface, resistant to impact and crush for transmission alternating loads
2. Internal oil passage supplies lubrication to cluster gear bearings and reduces seizure risk under high temperature
3. Precise 75 mm OD with reliable shoulder limit, maintains stable gear backlash and lowers transmission noise
4. Integrated flange for easy alignment, solid positioning reference, less chance of gear jumping after overhaul

FAQ 

Q: What faults will occur if cluster gear shaft is scored or worn?
A: Excessive gear backlash, persistent transmission noise and unstable power transfer. Severe damage includes broken bearings and gear teeth.

Q: Can 101-1366 fit other loader transmissions?
A: No. It is designed exclusively for 5130B, flange and oil passage layout do not match other models.

Q: What happens if oil hole on the shaft is blocked?
A: The cluster gear bearing loses lubrication and seizes rapidly, causing gear lock-up and loss of transmission power.

Q: Can excessive gear backlash be fixed just by replacing the cluster gear shaft?
A: Not always. If the cluster gear teeth are worn, shaft replacement alone cannot restore OEM backlash.
