Caterpillar s6k camshaft 5I-8068

Uncompromising Job-Site Durability: Caterpillar S6K Camshaft for Industrial Diesel Engines

This Caterpillar s6k camshaft (Part No: 5I-8068) is a critical replacement component within our Industrial Diesel Engine Parts inventory, specifically engineered for Caterpillar 320 series excavators and Mitsubishi-based industrial equipment. In heavy construction environments, the S6K engine endures frequent load changes and start-stop cycles. Over time, this can lead to lobe wear and valve train noise due to lubrication breakdown or soot contamination.

Ruich Value manufactures this camshaft using advanced chilled cast iron technology to match the OEM hardness specifications. By ensuring precise lift and duration profiles, our replacement camshaft restores the original valve timing and combustion efficiency of your heavy equipment. It is designed to withstand the rigorous demands of earthmoving machinery, offering a reliable, high-margin solution for fleet maintenance managers and engine parts distributors.

Technical Specifications for 5I-8068 Camshaft Casting

Technician’s Note: Installation & Inspection

When installing a new S6K camshaft, it is critical to inspect the camshaft bushings in the cylinder block for scoring or excessive clearance. We also strongly recommend replacing the tappets (lifters) at the same time. Using old, worn lifters on a new camshaft can destroy the lobe surface finish within the first 50 hours of operation, voiding the warranty.

Why Source Industrial Diesel Engine Parts from Ruich Value?

• Hardness & Durability: Our S6K camshafts feature Chilled Cast Iron lobes tested to HRC 50-55. This superior hardness prevents premature wear and pitting, significantly reducing warranty claims from your end-users.
• Dimensional Precision: Cam lobes are CNC ground to exact OEM lift and duration profiles. This guarantees perfect valve timing and fitment, saving your mechanics valuable installation time and preventing engine power loss.
• Dynamic Balancing: Each shaft undergoes strict dynamic balancing checks. This eliminates vibration at high RPMs, protecting the cam bearings and extending the overall engine service life.
• Inventory Power: We maintain “Ready Stock” for popular excavator numbers like 5I-8068. This supports urgent fleet breakdown repairs and allows for faster capital turnover for our distributors.
• Export Protection: All camshafts are coated in heavy-duty anti-rust oil and packed in reinforced wooden crates. We ensure zero rust or transit damage upon arrival, safeguarding your inventory value.

Technical FAQ: Caterpillar s6k camshaft 5I-8068

How do I verify if this 5I-8068 camshaft fits my CAT 320 excavator?

The 5I-8068 is the standard camshaft for the S6K and S6KT engines found in the CAT 320, 320L, and E200B series. However, some later models might use a different part number. The best way to identify the correct part is by checking the casting number on your old camshaft or providing your engine serial number prefix to our sales team.

Does the camshaft come with the drive gear installed?

Typically, we supply the S6K camshaft as a “bare shaft” without the gear, as the original gear is often reusable. If your gear is damaged or worn, please let us know when ordering, and we can supply a new gear or a pre-assembled unit upon request.

What is the material difference between this and the OEM shaft?

Our aftermarket 5I-8068 camshafts are manufactured from Chilled Cast Iron, which matches the material specification of the OEM part for this specific engine. This ensures the same wear resistance characteristics and compatibility with standard tappets used in Industrial Diesel Engine Parts applications.
