Full details

The Gunson Clikadjust Tappet Adjuster (G4094) is designed for mechanics and automotive enthusiasts working on push-rod or OHC engines requiring precise valve clearance adjustments. Its key benefit is enabling micro-adjustments without the need for feeler gauges after initial setup, leading to smoother engine performance. A potential caveat is that it requires a basic understanding of valve adjustment procedures for optimal use.

FAQs

Can I use this tool without feeler gauges at all?

While the tool's micro-adjustment is designed to reduce reliance on feeler gauges for fine-tuning, an initial setup using feeler gauges is recommended to establish the baseline clearance accurately.

What types of engines is this tool NOT suitable for?

This tool is not suitable for engines with overhead camshafts (OHC) that do not have flat-head top adjustment screws, or for engines that use shims or other methods for valve clearance adjustment.

How do I clean the Gunson Clikadjust Tappet Adjuster?

Wipe the tool clean with a dry cloth after each use to remove any dust or oil. Store in a clean, dry place.

What is the benefit of micro-adjustment?

Micro-adjustment allows for very small, incremental changes to the tappet gap, enabling precise setting of valve clearance for optimal engine performance and reduced noise.

Does the 1/2 inch drive fit all lock nuts?

The 1/2 inch drive refers to the socket size. It is compatible with any lock nut designed to accept a 1/2 inch drive fitting.

How does this tool help with worn tappets?

Worn tappets can lead to inconsistent valve clearance. The precision of the Clikadjust tool allows you to accurately set and maintain the correct clearance, even with some wear present.

Troubleshooting

Difficulty turning the adjustment screw

Ensure the lock nut is sufficiently loosened. Check for any debris in the adjustment screw mechanism.

Inability to achieve precise adjustment

Verify that the tool is correctly seated on the adjustment screw and lock nut. Ensure the 'Clikadjust' feature is functioning smoothly; re-grease lightly if necessary.

Tool slips off the adjustment screw

Confirm the tool's socket is the correct size for the lock nut and that it is fully engaged. Ensure the adjustment screw head is clean and not stripped.

Pros and Cons

Pros

  • Enables highly accurate valve clearance adjustments.
  • Streamlines the tappet adjustment process, saving time.
  • Reduces the need for constant feeler gauge use.
  • Compatible with a wide range of common engine types.
  • Provides a more precise feel for worn tappets.

Cons

  • Requires initial setup and understanding of valve adjustment principles.
  • Not suitable for engines with different tappet adjustment mechanisms.
  • Can be cumbersome if access to tappets is restricted.
  • The 'Clikadjust' feature requires careful initial setting to be effective.

Setup, Compatibility & Care

Setup: Begin by understanding the specific valve clearance specifications for your engine. Loosen the lock nut on the tappet adjuster. Use the Gunson tool to rotate the adjustment screw. Once the desired clearance is achieved (often set initially with feeler gauges), re-tighten the lock nut. The tool's micro-adjustment feature is then used for fine-tuning without significant disruption.

Compatibility: This tool is designed for all push-rod valve engines and OHC engines that use flat-head top adjustment screws. It is compatible with any lock nut that accepts a 1/2 inch drive.

Care: After use, clean the tool with a dry cloth to remove any debris. Store it in a dry environment to prevent corrosion. Avoid excessive force that could damage the micro-adjustment mechanism.
