description

The 200-4495 idler shaft is fitted inside the gear housing of C7, C9, C9.3 and 3126 engines. The idler gear rotates on this shaft with bushing or bearing. It transmits timing power and keeps gear mesh tension. It is widely used on Cat 336, 330 excavators. Under cyclic load and high-temperature oil, journal scuffing will cause gear noise, timing fluctuation and even valve collision when teeth skip.

Product Advantages

1. One-piece forging delivers uniform internal structure, resisting bending under radial impact from gears
2. Precision ground journals with tight roundness and straightness tolerance for smooth bushing rotation and low noise
3. Controlled hardening depth prevents seizure and wear, stable performance in hot engine oil environment
4. OEM dimensional standard, direct fit with gear housing bore and idler bushing without machining

FAQ 

1. Can the shaft be reused with light scratches on journal?
Light scratches can be polished and reused after checking clearance. Replace it if step wear, scuffing or bending occurs.

2. Is 200-4495 interchangeable with other 74 mm OD idler shafts?
Not necessarily. They differ in length, locating shoulder and oil hole layout. It is exclusive for C7/C9/C9.3/3126.

3. Why does the new shaft wear out quickly after installation?
It is usually caused by blocked oil passages, worn bushing or misaligned gear mesh. Replacement of shaft alone cannot solve root cause.

4. Does it fit both 3126B and C9?
This part number works for both. Verify gear housing drawing before ordering.
