description

The 188-5158 is one-piece camshaft for C11 engine. It drives roller lifters to synchronize valve movement and fuel injection actuation. This mid-high power electronic engine runs under variable load conditions on construction sites and highways. Lobe pitting, spalling or journal scoring leads to power loss, unbalanced cylinder performance, rough idle and high fuel consumption. Severe damage triggers valve-to-piston contact. Its cam profile and lift are exclusive for C11 and not interchangeable with C9 or C13 camshafts.

Product Advantages

• Withstand mechanical stress without compromising their performance or safety
• Reduces friction and provides smooth rotation

1. OEM cam profile for C11, well matched with electronic fuel actuator for stable combustion under variable load
2. One-piece forging with dense grain, vibration and heat resistant for long continuous operation
3. Uniform hardened layer protects lobes and journals from abrasive oil contamination
4. Sold separately without gear, reusable functional gear reduces overhaul expense

FAQ 

1. Does 188-5158 fit C13 engine?
No. C11 and C13 differ in cam lift, journal size and timing calibration, non-interchangeable.

2. Can the camshaft stay in service with minor scattered pitting and no cracks?
Pitting spreads rapidly under variable cyclic load, replacement is recommended.

3. 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.

4. Can this camshaft fit C9 engine?
No. Bore, stroke, cam profile and actuator structure are different, not compatible.
