description

It is forged from alloy steel with induction hardened cam lobes for high positioning accuracy, impact resistance and wear resistance. The 3406B/C is a classic inline six-cylinder heavy mechanical pump diesel engine. This camshaft drives valve rocker assembly and fuel pump to coordinate valve opening and fuel delivery timing. It is widely fitted on 627G/637G scrapers, D8N dozers, 769D off-highway trucks and stationary generator sets, suitable for long continuous heavy-duty operation of legacy machines in Africa and Middle East.

Maintenance & Replacement Tips

Mark timing marks on crankshaft and cam gear before disassembly. Timing error on 3406 mechanical pump engine can cause valve-to-piston collision. Replace lifters, cam bearings, thrust washers and oil seals together with the camshaft. Lubricate lobes and journals fully with recommended engine oil before assembly. Rotate crankshaft manually twice to check binding. Monitor exhaust smoke, idle stability and oil pressure after startup.

FAQ 

Q: Can 176-3209 fit 3408 engine?
A: No. 3408 has different cylinder count, cam stroke and fuel curve, they are not interchangeable.

Q: How many 176-3209 camshafts are needed for one 3406C engine?
A: 3406B/C is inline engine, only one camshaft is required per engine.

Q: Can a slightly worn camshaft be reground and reused?
A: Regrinding for reuse is not recommended. It will alter cam lift and disrupt fuel and valve timing.
