description

It is forged from alloy steel with induction hardened cam lobes and quenched & tempered shaft body for good fatigue and wear resistance. The 3306 is a classic inline six-cylinder mechanical pump engine. This single camshaft drives both valve rocker assembly and fuel injection pump to keep injection advance and valve timing coordinated. It fits 966C,966D wheel loaders, D6C/D6D dozers and stationary generator sets, widely used for maintenance of legacy machines and steady long-run operation in remote Middle East and Africa sites.

Product Advantages

1. Cam lift profile matches OEM specification for 3306 mechanical pump, delivering reliable low-speed torque and stable injection timing.
2. Precision ground journals with tight coaxiality control, reducing uneven bearing wear and oil pressure drop.
3. Heat treatment is optimized for start-stop shocks of legacy mechanical pump engines to mitigate cam pitting and spalling.
4. Direct replacement part with original timing reference, compatible with existing camshaft gear.

FAQ 

Q: Can 7E-9980 interchange with 4P-6897?
A: No. They differ in cam lift and fuel delivery curve, made for different 3306 versions and cannot be mixed.

Q: How many 7E-9980 camshafts are needed for one 3306 engine?
A: 3306 is inline engine, only one single camshaft is required per engine.

Q: Can old lifters with intact appearance be reused with the new camshaft?
A: It is not recommended. Lifters wear in with the original cam. Hidden surface wear will score the new cam lobes quickly.
