description

It is forged from alloy steel billet with induction hardened cam lobes for stable fatigue and wear resistance. The 3508B is a V8 engine with dual camshaft layout. This rear camshaft manages intake and exhaust valve timing for the rear cylinder group and coordinates fuel injection logic. It is widely applied on stationary generator units and oilfield drilling power modules for long continuous constant-speed operation in remote sites of Middle East and Africa.

Part No.: 452-2502
Name: Left Rear Camshaft
Application: CAT 3508B engine (generator set, oilfield power module)
Material: Alloy steel, induction hardened cam lobe surface
Layout: Rear bank camshaft, used in pair with front camshaft 452-2503

Maintenance & Replacement Tips

Mark timing marks of front cam gear, rear cam gear and crankshaft before disassembly. 3508B has very narrow timing tolerance, misalignment will cause valve-to-piston collision. Replace cam bearings, thrust washers and hydraulic lifters together. Lubricate journals and lobes fully with recommended engine oil during assembly. Rotate crankshaft manually for at least two full cycles to check binding. Monitor oil pressure, exhaust temperature and overall vibration during commissioning.

FAQ 

Q: Can 452-2502 be swapped with front camshaft 452-2503?
A: No. Cam lift and phase angle are different for front and rear banks. Reversed installation will damage valve components.

Q: How many 452-2502 camshafts does one 3508B engine need?
A: One V8 3508B engine requires one 452-2502 rear camshaft, matched with one 452-2503 front camshaft as a set.

Q: Can 452-2502 fit into 3512B engine?
A: It is not interchangeable. The 3512B has different cylinder count and cam stroke parameters, direct fitment is unavailable.
