description

This is a single ring gear, different from one-piece 101-1363 compound idler which has dual gear sections. It only has 92 teeth and no 35-tooth section. Mounted on 4P-5437 (74.9mm OD) support shaft, it transfers power to camshaft and injector drive gear. Its meshing accuracy directly affects injection and valve timing stability.

It is forged alloy steel with carburized and hardened teeth. Tooth root is filleted for stress relief to resist fatigue crack under cyclic mining load. Bore surface is precision honed to maintain coaxiality with shaft and bearing and reduce eccentric wear.

It fits heavy-duty mechanical injection Cat engine gear housing for mining trucks and stationary generator sets. Gear only, bearing, spacer and 4P-5437 support shaft sold separately. Cannot replace 101-1363 compound idler directly, verify the whole gear train layout before ordering.

Product Advantages

1. Carburized hardened alloy steel teeth, reinforced tooth root for anti-breakage under heavy shock load
2. OEM module and pressure angle for 92T, matched backlash with mating idler for smooth quiet transmission
3. Honed bore with tight coaxiality, even tooth wear and slow timing drift after long runtime
4. Separate single gear design, replace this stage individually instead of whole compound idler to cut overhaul cost

FAQ 

Q: What faults occur if tooth surface is pitted or worn?
A: Excessive backlash, rhythmic gear noise, gradual timing drift, power loss and rough idle, broken teeth and valve-piston contact in severe cases.

Q: Can 4P-5459 replace 101-1363 compound idler?
A: No. It only has 92T single section without 35T section, the gear ratio and transmission chain cannot be satisfied.

Q: What happens if gear bore wears out?
A: Gear eccentricity and uneven load, accelerated tooth wear and timing drift, high risk of valve-piston collision.

Q: What risk if I reuse old bearing with new gear?
A: Worn bearing creates excessive clearance and wobble, the new gear teeth will pit and wear unevenly very quickly.
