Plastigage Checks Bearing Clearances

Check bearing clearances the modern, fast, accurate way with Hastings Plastigages.

Plastigages are a special extruded plastic thread with accurate controlled “crush” properties. It is extremely handy for checking main and connecting rod bearing clearances, oil pump cover-to-gear clearances, and for many other clearance checks.

Each box of Plastigaes contains 12 strips in individually calibrated envelops, usually enough to check 12 engines. Available in four clearance ranges.
