description

This camshaft is a core valve-train component for the right cylinder bank of high-power C27 V diesel engines. Cam lobes actuate tappets and rocker assemblies to precisely control valve lift and timing, matching electronic fuel injection system for stable combustion. It is widely applied on mining bulldozers, heavy mining trucks and power generator sets.
It is made of carbon steel with heat-treated cam surfaces for outstanding pitting and spalling resistance under long-term heavy mining shock loads. Journals, cam profiles and gear mounting reference are machined strictly to OEM drawings with stable timing phase.
This camshaft is exclusive for the right bank of C27. It has different timing profile from left bank 421-0071 and they cannot be interchanged. It should be matched with correct camshaft bushings, tappets and pushrods during overhaul to maintain concentricity and reduce premature wear.

Part Number: 421-0097
Name: Right bank camshaft
Applicable Models: Caterpillar C27 engine; D10 bulldozer, 773 mining truck, large generator set

Product Advantages

1. Carbon steel base with heat-treated cam lobes, wear and impact resistant for continuous heavy mining operation of C27
2. Right-bank dedicated cam profile matches injection strategy and reduces engine fault codes
3. Precise journal tolerance and optimized oil passage layout provide sufficient lubrication and lower scoring risk
4. Consistent positioning reference for easy alignment, less timing drift and shorter overhaul calibration time

FAQ 

Q: What faults are caused by pitting and spalling on cam lobes?
A: Insufficient valve lift, poor air flow, power loss, higher fuel consumption and valve train noise, engine derate in severe cases.

Q: Can 421-0097 interchange with 421-0071?
A: No. 421-0071 is left-bank camshaft with different timing profile, interchange will cause valve timing failure.

Q: What damage will blocked oil passages bring on C27?
A: Poor lubrication scores cam lobes and journals rapidly, leading to premature camshaft failure and misfire.

Q: What risk if only replacing camshaft without changing bushings?
A: Worn out-of-round old bushings create abnormal clearance with new journals, which may score the camshaft quickly and cause early failure.
