4P-7696 Caterpillar low overlap camshaft for engine spare part

Product Advantages

1. Custom low-overlap cam profile suppresses exhaust gas recirculation, delivering smooth idle and improved smoke control at fixed speed
2. One-piece forged construction with dense grain structure, excellent fatigue resistance for non-stop continuous service
3. Uniform hardened layer on lobes and journals reduces abrasive wear for steady low-speed operation
4. OEM drop-in size, only compatible with 3306 engines originally calibrated for low overlap, not interchangeable with standard cams

FAQ 

1. Can 4P-7696 interchange with 4P-7695?
Interchange is not recommended. They have different timing settings for different 3306 sub-models, altering idle and smoke performance.

2. Does it fit 3304 engine?
No. 3304 and 3306 differ in stroke, cam mounting distance and lift profile, 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 flat tappets.

4. Can construction 3306 engines use this low-overlap cam?
Only units originally calibrated for low overlap are suitable. Most heavy-duty earthmoving 3306 use high-overlap cams.
