Komatsu S6D120 Camshaft 6114-41-1110

Maximum Durability: Komatsu S6D120 Camshaft for Industrial Diesel Engine Parts

Featuring high-nickel alloy steel and deep induction-hardened lobes, this Komatsu S6D120 Camshaft (OEM: 6114-41-1110) delivers superior S6D120 Cam Shaft performance for high-load mining and earthmoving cycles. As a vital component in our Industrial Diesel Engine Parts wholesale catalog, this shaft is precision-engineered to restore exact valve timing in heavy-duty 120mm bore powerplants.

In extreme operating environments, maintaining the structural integrity of your valve train is essential for preventing power loss. This camshaft specifically addresses the accelerated wear that leads to lost lift in equipment like the PC400-5 and D85 Bulldozer. By adhering to strict geometric tolerances across all journals, it ensures that your engine overhaul meets professional reliability standards.

Technician’s Note: Installation & Inspection

Technician’s Note: When overhauling the S6D120 timing chest, always verify the cam follower (tappet) surface condition. Installing this new shaft without replacing followers that show micro-pitting will result in catastrophic failure of the new lobes within the first 200 service hours.

Why Source Industrial Diesel Engine Parts from Ruich Value?

• Hardness & Durability: Our camshafts utilize chilled iron casting with deep induction hardening (HRC 52+), preventing premature lobe flattening and minimizing warranty claims for distributors.
• Dimensional Precision: Every journal is finished via CNC micropolishing, ensuring perfect oil film clearance and reducing installation labor for fleet mechanics.
• Dynamic Balance: All shafts are 100% dynamically balanced to eliminate high-RPM vibration, protecting the engine’s timing gear train from harmonic fatigue.
• Inventory Power: We maintain ready stock for high-demand Komatsu numbers like 6114-41-1110, facilitating faster capital turnover for parts wholesalers.
• Export Protection: All units are treated with VCI anti-rust oil and secured in reinforced wooden crates to ensure zero-defect arrival for international sea freight.

Technical Q&A: Komatsu S6D120 Camshaft

Q: Can this camshaft be used in the naturally aspirated 6D120?

A: While journals are similar, the timing profile for the S6D120 (6114-41-1110) is optimized for turbocharged airflows. We recommend using the specific NA part number for non-turbo applications to ensure optimal performance.

Q: Does the camshaft include the woodruff key for the timing gear?

A: Our standard supply is the bare camshaft. However, we can provide the timing gear, key, and thrust plate as a wholesale kit for fleet customers looking to minimize assembly downtime.

Q: What is the primary cause of “Lobe surface spalling” on this model?

A: Most spalling in S6D120 units stems from oil starvation at high engine hours or the use of incorrect oil grades in heavy bulldozing applications. Our chilled iron casting helps combat this through superior surface density.
