Tech Tips on Use:
Remove the engine oil pan to reveal the big-end and its retaining set-screws. Remove excess oil and release the big-end shells by unscrewing the set-screws. Apply a smear of grease to the journal and small quantity of silicone release agent to the shell.
Trim a length of PLASTIGAGE to fit across the journal using the grease to hold it in place. Replace the shell and tighten the set-screws to the recommended torque setting, without rotating the journal.  Now remove the shell to reveal the PLASTIGAGE which will have been spread across the bearing surface as a stripe or band. Match the width of the stripe against the calibrated gauge on the package, and read the clearance.
The PLASTIGAGE stripe ideally should be removed with a clean oily cloth or degreasing solvent.  However, any remaining PLASTIGAGE residue left behind will simply dissolve in motor oil and will not harm the engine in any way.
