description

It is forged from alloy steel billet with induction hardened cam lobes for reliable wear and shock resistance. The 3306 is a classic inline six-cylinder mechanically injected engine. This camshaft actuates valve train and fuel pump together to keep injection and valve timing synchronized. It is widely fitted on 966D,966E wheel loaders, D6D dozers and stationary generator sets, suitable for cyclic variable-load operation at quarries and mine transfer sites in Middle East and Africa.

Name: Engine Camshaft
Application: CAT 3306 engine; 966D/966E loader, D6D dozer, generator set
Material: Alloy steel, induction hardened cam lobe surface
Structure: Inline single camshaft

Maintenance & Replacement Tips

Mark crankshaft and cam gear timing marks before disassembly. Timing error on 3306 mechanical pump engine will cause valve-to-piston collision. Replace hydraulic lifters, cam bearings and oil seals together with the camshaft. Lubricate lobes and journals fully with recommended engine oil during assembly. Rotate crankshaft manually twice to check binding. Monitor oil pressure, abnormal noise and exhaust smoke after commissioning.

FAQ 

Q: Can 4P-6897 fit 3304 engine?
A: No. 3304 has different cylinder count, cam lift and stroke parameters. Timing curve does not match, interchange is invalid.

Q: How many 4P-6897 camshafts are needed for one 3306 engine?
A: 3306 is inline six-cylinder engine, only one 4P-6897 camshaft is required per engine.

Q: Can I replace only the camshaft while keeping unworn lifters?
A: It is not recommended. Lifters are worn-in matched with the original cam. Used lifter surfaces will rapidly score the new cam lobes.
