description

The 4P-0730 is a pre-assembled camshaft group for 3408 engine, supplied with camshaft, timing gear, thrust washer and retaining parts to reduce separate part sourcing. The V8 3408 serves heavy-duty applications including D10 dozer, marine power and oilfield fracturing units under sustained high cylinder pressure. This camshaft has dedicated lift and phase settings for one cylinder bank, driving roller lifters to maintain accurate valve events. Lobe spalling or journal scoring causes uneven combustion and excessive smoke. Severe failure may lead to valve-piston contact. The grouped assembly is ideal for full overhaul to avoid mismatching risks.

Product Advantages

1. Pre-matched from factory, with concentricity and end play pre-checked for faster overhaul installation
2. Dedicated cam profile for 3408, optimizing air exchange and stable combustion under heavy load
3. One-piece forging resists cyclic impact, suitable for non-stop full-load mining and marine service
4. OEM drop-in size, fits original cylinder head bearing housing and drive structure without modification

FAQ 

1. Can 4P-0730 be swapped between left and right cylinder bank?
No. Left and right banks have different timing and lift profiles. This group fits only one bank.

2. Does 4P-0730 fit 3406 engine?
No. 3406 and 3408 differ in block layout, cam mounting distance and gear tooth design.

3. Can the gear with minor pitting stay in service?
Pitting on gear teeth is fatigue damage. Vibration will escalate under heavy load, continued use is not advised.

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