description

This 9Y-9133 is one-piece valve camshaft dedicated to the right cylinder bank. Its lobe lift and duration follow factory calibration. It drives valve tappets to control valve timing of right bank and coordinates power stroke with left bank. Forged alloy steel blank with deep high-frequency hardened and mirror finished cam lobes, stable under high temperature and cyclic impact load. It is widely used on mining, marine and generator engines, usually replaced with cam bearings, thrust washers and tappets during overhaul.

Part No.：9Y-9133
Name：CAT right bank camshaft
Mounting position：Right cylinder bank
Structure：One-piece full-length valve camshaft for single bank
Material：Alloy steel forging
Surface treatment：Deep high-frequency hardening, mirror grinding

Advantages

1. Right bank exclusive cam profile, phase matched with left camshaft for uniform cylinder combustion
2. Sufficient hardened layer, resistant to pitting, spalling and scoring during long continuous running
3. Strict journal coaxiality control, uniform bearing load and low seizure risk
4. Independent single bank design, separate overhaul available without disassembling left bank

FAQ 

Q1：Can 9Y-9133 be interchanged with 9Y-9132?
A：No. Lobe lift, layout and timing parameters differ, they fit different engine versions and are not compatible.

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

Q3：What typical faults will worn right camshaft cause?
A：Valve noise on right bank, low power on right side, large exhaust temperature difference, high fuel consumption and rough idle.

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