description

It is forged from high-strength alloy steel with induction hardened cam lobes for reliable wear and fatigue resistance. The 3516 is a V-type 16-cylinder high-power diesel engine equipped with four separate camshafts for left front, left rear, right front and right rear banks. 4P-8353 serves the left rear bank to drive valve train and fuel pump, keeping injection and valve timing synchronized. It is widely applied on oilfield power, offshore auxiliary power and stationary mine generator units, suitable for long continuous high-load operation in remote Middle East and Africa sites.

Maintenance & Replacement Tip

Mark independent timing marks on crankshaft and four camshaft gears before disassembly. 3516 has complex timing logic. Misalignment of any single camshaft will cause valve-to-piston collision. Inspect lifters, cam bearings, thrust washers and oil seals for the left rear bank during replacement. Lubricate lobes and journals fully with recommended engine oil before assembly. Rotate crankshaft manually several times to verify no binding or interference. Monitor this bank exhaust temperature, overall vibration and oil pressure after startup.

FAQ 

Q: Can 4P-8353 interchange with left front camshaft 7C-2054?
A: No. Left front and left rear camshafts have different phase and lift. Wrong fitment causes bank power imbalance and severe engine vibration.

Q: How many 4P-8353 camshafts does one 3516 engine need?
A: Only one 4P-8353 is fitted for the left rear bank. The engine needs four camshafts in total as a complete set.

Q: Do thrust washers of other banks need replacement together?
A: Only thrust washers for the left rear bank require replacement. Parts of other banks can be reused if clearance and condition remain good.
