Short Description:

Compound idler gear for Caterpillar 5130B gear housing, with 92-tooth and 35-tooth integrated gear sections, mounted on 101-1366 cluster gear shaft, transmits torque, adjusts rotation direction, controls gear ratio and stabilizes timing gear backlash.

description

This compound idler is one-piece double gear. It rotates on the stationary cluster gear shaft. The 92T section meshes with upstream drive gear and the 35T section meshes with downstream driven gear. It changes rotation direction and sets reduction ratio to synchronize crankshaft, camshaft and injector drive gear timing for 5130B engine gear train.

It is made of alloy cast steel. Both 92T and 35T gear teeth are carburized and hardened. The tooth root retains good toughness while tooth surface resists pitting and impact fatigue. Bore and bearing running surface are precision machined with tight coaxiality control to prevent uneven wear and noise.

It is used for gear housing overhaul of Caterpillar 5130B loader, commonly matched with 101-1366 cluster gear shaft and 101-1369 camshaft drive gear. The 92+35 tooth combination defines fixed gear ratio, cannot be replaced by single-section gear or idler with different tooth count.

Product Advantages

1. One-piece cast steel compound structure, double carburized teeth, impact resistant for long heavy-duty loader operation
2. OEM 92+35 tooth ratio matches gear train, stabilizes camshaft and injector drive timing phase
3. Tight coaxiality ensures even load distribution, reduces eccentric wear and rhythmic gear housing noise
4. Precise bore tolerance fits matched shaft and bearing, stable backlash and low timing drift after overhaul

FAQ 

Q: What faults occur if one section of teeth is pitted?
A: Excessive backlash, gear noise, timing drift and unstable power transfer, broken teeth and valve-piston contact in severe cases.

Q: Can I replace only one gear section of 101-1363?
A: No. It is one-piece compound gear with factory coaxial calibration, single section replacement is not supported.

Q: What risk if I keep the old bearing and only replace the idler gear?
A: Worn bearing creates excessive clearance and gear eccentricity, the new compound gear will wear unevenly and fail quickly.

Q: What happens if I use an idler with wrong tooth ratio?
A: Cam speed and injection timing will be out of sync, engine fails to start and valve-piston contact may occur.
