description

This 9Y-9136 is complete camshaft assembly pre-assembled with key and thrust components for one cylinder bank. It drives valve tappets to control intake and exhaust valve timing. Forged alloy steel blank with deep high-frequency hardened and mirror finished cam lobes, good fatigue and heat resistance under continuous heavy load. It matches with 9Y-9132 and 9Y-9133 in the same engine series. Cam bearings, tappets and thrust washers are normally replaced together during overhaul.

Part No.：9Y-9136
Name：CAT camshaft assembly
Mounting position：Single cylinder bank

Advantages

1. Pre-assembled set with factory coaxiality inspection, minimize valve timing error
2. Adequate hardened layer, resistant to pitting, spalling and scoring under heavy load
3. Independent single bank assembly, separate repair without disassembling opposite bank
4. Phase matched with 9Y-9132 and 9Y-9133, balanced engine power output

FAQ 

Q1：Can 9Y-9136 replace 9Y-9132 right camshaft directly?
A：No. Lobe layout, lift and timing calibration differ, they fit different bank versions.

Q2：Must the camshaft on the other bank be replaced together?
A：Not mandatory. Inspect the other camshaft separately and replace if worn severely.

Q3：What typical faults will worn camshaft assembly cause?
A：Valve train noise, low power on single bank, unbalanced exhaust temperature, high fuel consumption and rough idle.

Q4：Can old cam bearings be reused with new camshaft assembly?
A：Not recommended. Bearings and journals are mating friction pairs, better to replace together.
