description

The 7C-0668 is dedicated camshaft for the right front bank of V-3512 engine, matched with the left front camshaft. It drives roller lifters of this bank to regulate intake and exhaust valve events. This large-displacement engine runs continuously under high cylinder pressure for marine and oilfield service. Lobe damage or journal scoring causes uneven cylinder performance, unbalanced exhaust temperature and power loss. Severe failure may trigger valve-piston contact. Its timing profile is exclusive for the right front bank and cannot be relocated freely.

Product Advantages

1. OEM dedicated timing profile for the right front bank of 3512, delivering balanced air exchange and consistent cylinder combustion
2. One-piece forged blank with dense grain structure, resistant to cyclic impact for non-stop marine and oilfield cycles
3. Uniform hardened layer on lobes and journals delivers reliable abrasion resistance against contaminated lubricating oil
4. Drop-in replacement dimension, compatible with original bearings, gear and thrust parts of the same bank

FAQ 

1. Can 7C-0668 be installed on the left front bank?
No. Right front and left front camshafts have different timing and lift profiles, mixing them breaks engine timing.

2. Does it fit 3516 engine?
No. 3512 and 3516 differ in cylinder layout, cam mounting distance and timing parameters, non-interchangeable.

3. Can the camshaft stay in service with scattered shallow pitting and no crack?
Light isolated pits can be monitored temporarily. Replace it if pitting spreads or spalling occurs to protect roller lifters.

4. What risk if I install new camshaft and reuse old lifters?
Mismatched contact surfaces will trigger rapid lobe pitting and spalling during break-in and lead to early failure.
