258-8834 Caterpillar front engine camshaft for engine spare part

Product Advantages

• Helps in controlling the valve timing, the camshaft optimizes the engine’s power output, fuel efficiency, and exhaust emissions
• Withstands mechanical stress, without compromising performance or safety

1. OEM dedicated timing profile for front cylinders of C15, synchronized valve and fuel injection for stable heavy-load combustion
2. One-piece forging with high rigidity, heat resistant and fatigue resistant for long continuous operation
3. Uniform hardened layer reduces abrasive wear caused by contaminated lubricating oil
4. Sold separately without gear, reusable functional gear cuts overhaul expense

FAQ 

1. Can 258-8834 be installed on the rear bank?
No. Front and rear camshafts have different lift and timing, mixing them breaks engine timing.

2. Does it fit C18 engine?
No. C15 and C18 differ in journal size, cam profile and timing calibration, non-interchangeable.

3. Can the camshaft stay in service with minor scattered pitting and no cracks?
Pitting spreads rapidly under continuous heavy load of mining trucks, replacement is recommended.

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