Lang Tools 23-Blade Feeler Gauge for Cummins Valve Adjustment (3072)

The Lang Tools 23-Blade Feeler Gauge for Cummins Valve Adjustment (3072) is a specialized instrument designed for accurately setting valve lash clearances on heavy-duty truck engines, with a particular focus on Cummins diesel engines. Proper valve adjustment is critical for engine efficiency, performance, and longevity. This feeler gauge provides the necessary precision and access for maintenance professionals and enthusiasts working on these robust powerplants. Its design prioritizes functionality, featuring individual blades that can be easily removed and handled, along with a strategic offset to navigate the intricate components of engine compartments.

KEY FEATURES AND BENEFITS:

• Precise Valve Lash Measurement: Offers a range of 0.008" to 0.030" with 23 distinct blades, ensuring highly accurate measurements for optimal valve clearance settings on heavy-duty truck engines.
• Enhanced Accessibility: Each 6-inch blade includes a 1-inch long, 90-degree offset, allowing users to reach and measure valve clearances in tight or obstructed areas common in large diesel engines.
• Individual Blade Use: The loose set of blades allows for easy removal of a single desired thickness, providing flexibility and convenience during adjustment procedures without the other blades interfering.
• Durable Stainless Steel Construction: Made from stainless steel, the blades resist corrosion and wear, ensuring long-term accuracy and reliability in demanding shop environments.
• Clear Identification: Each blade is etched with its size, making quick selection and identification straightforward, improving work efficiency.

SPECIFICATIONS:

• Number of Blades: 23
• Blade Range: 0.008" to 0.030"
• Blade Length: 6 inches
• Blade Offset: 1-inch long, 90-degree offset
• Material: Stainless Steel
• Included in Product: 23 loose feeler gauge blades on a retaining ring

HOW TO USE:

1. Prepare the Engine: Ensure the engine is cool and properly positioned according to the manufacturer's service manual for valve adjustment. This typically involves rotating the engine to Top Dead Center (TDC) for specific cylinders.
2. Identify Correct Clearance: Consult the engine's service manual (e.g., for your specific Cummins model) to determine the correct intake and exhaust valve lash specifications.
3. Select Blade: From the Lang Tools 3072 set, select the feeler gauge blade corresponding to the required valve lash clearance. Remove it from the retaining ring for easier handling.
4. Insert and Measure: Carefully insert the chosen feeler gauge blade between the valve stem and the rocker arm or adjusting screw. Use the 90-degree offset to navigate around engine components if necessary.
5. Check Fit: The blade should slide in with a slight, consistent drag. If it's too loose, the clearance is too wide; if it won't fit or is too tight, the clearance is too narrow.
6. Adjust Valve Lash: If adjustment is needed, use the appropriate wrenches and screwdrivers to loosen the lock nut and turn the adjusting screw. Re-check the clearance with the feeler gauge until the desired drag is achieved.
7. Tighten Lock Nut: While holding the adjusting screw in place, tighten the lock nut to the specified torque. Re-verify the clearance one final time to ensure it didn't change during tightening.
8. Repeat: Continue this process for all valves requiring adjustment.
