description

This camshaft is a core valve-train component for heavy-duty C15 and C18 diesel engines. Its cam lobes actuate tappets and rocker arms to control valve lift and timing, matching ECU fuel injection strategy. It is widely used as replacement part for overhaul of mining trucks, large excavators and generator sets.

It is forged from alloy steel. The cam working surfaces are hardened by high-frequency quenching with uniform hardness, offering strong resistance to pitting and spalling. It can withstand long continuous heavy-duty and impact loads and reduce premature cam lobe wear.

Journals, cam lift and helix angles are machined strictly per OEM drawings with stable timing reference. It supports standard valve lash adjustment after installation and features good compatibility with matched camshaft bearings, tappets and pushrods.

Product Advantages

1. Forged alloy steel base with hardened cam surface, wear and impact resistant for C15/C18 heavy-duty operation
2. Accurate cam lift and timing parameters to maintain stable power output and control fuel consumption and emission
3. Tight journal tolerance reduces eccentric wear of bearings and extends service life of the whole valve train
4. Brand-new finished part, direct drop-in installation without extra machining to shorten downtime

FAQ 

Q: What faults will be caused by pitting and spalling on cam lobes?
A: Insufficient valve lift, poor air intake and exhaust, power loss, higher fuel consumption and valve train noise. Severe damage to valves and pistons may occur.

Q: Can 332-7297 interchange with 332-7298?
A: Direct interchange is not allowed. They are designed with different cam lift and timing parameters for different engine versions, interchange will lead to timing failure.

Q: What causes stiff rotation after camshaft installation?
A: Common causes include misaligned oil holes, deformed pressed bushings or misaligned timing gear. Inspect item by item; do not force crankshaft rotation.

Q: What risk if only replacing camshaft without replacing bearings during overhaul?
A: Worn out-of-round old bearings will create abnormal clearance with new journals, which may quickly score the camshaft and cause secondary damage.
