Frequently Asked Questions
What is the SPTCF-SHIM-1.95?
The Supertech SPTCF-SHIM-1.95 is a 1.95mm precision cam follower shim used to adjust valve clearance in engines equipped with Supertech bucket-type cam followers. It is hardened tool steel ground to accurate thickness for repeatable lash adjustment.
How do I know if I need the 1.95mm shim or a different thickness?
The correct shim thickness is determined during valve clearance measurement with the cam followers and camshaft installed. Measure the actual lash against the factory specification, then calculate the required shim thickness to bring the clearance within spec. A micrometer is required for accurate measurement.
Is the SPTCF-SHIM-1.95 compatible with the Supertech cam follower system for Honda K-series engines?
Supertech cam follower shims are used across multiple platform-specific cam follower applications. Verify the required shim diameter and thickness specification for your specific engine application against Supertech's catalog before ordering the SPTCF-SHIM-1.95.
What happens if valve clearance is set incorrectly due to a wrong shim thickness?
Incorrect valve clearance can result in valve train noise, premature wear on the cam lobes and followers, loss of power from incorrect valve timing, or in severe cases valve-to-piston contact. Accurate shim selection is critical during any engine assembly or rebuild.
Can the SPTCF-SHIM-1.95 be used in both intake and exhaust positions?
Cam follower shims can typically be used in both intake and exhaust positions provided the diameter and thickness match the required clearance specification. Confirm that your engine's intake and exhaust follower buckets accept the same shim diameter before ordering.
Do I need to replace all shims at once or just the ones out of spec?
Only shims that are not bringing valve clearance within the factory specification need to be replaced. It is common to replace individual shims during a valve clearance check rather than replacing an entire set at once.
Is the SPTCF-SHIM-1.95 available in other thickness increments?
Supertech produces cam follower shims in multiple thickness increments to allow fine valve clearance adjustment. Contact Black Ops Auto Works for availability of other SPTCF-SHIM thickness options for your build.
What tools do I need to replace cam follower shims?
Shim replacement requires a valve spring compressor appropriate for bucket tappet applications, precision measuring tools including a micrometer or dial gauge, and a clean workspace to avoid contamination. Cam follower shim replacement is an advanced engine procedure best performed by an experienced engine builder.
Installation Instructions
- Remove the camshaft(s) from the cylinder head following the engine manufacturer's service procedure.
- Lift out the cam follower buckets from each cylinder and retrieve the existing shims.
- Measure each shim thickness with a micrometer and compare actual valve clearance against the factory specification.
- Select the appropriate Supertech SPTCF-SHIM-1.95 or other thickness shim to bring each lash within specification.
- Install the new shim in the cam follower bucket and reinstall the bucket in the cylinder head.
- Reinstall the camshaft(s) and perform a final valve clearance verification before reassembling the engine.
