Plastigauge - Measure Engine Bearing Clearance

Perhaps the most widely used application of PLASTIGAUGE is in the measurement of clearance in plain automotive bearings. This application is described in detail:

Remove the engine sump cover to reveal the big-end and its retaining set-screws. Remove surplus 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 PLASTIGAUGE 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 PLASTIGAUGE which will have been spread across the bearing surface as a stripe or band. Match the width of the stripe against the calibrated gauge card supplied and read off the clearance.

Ideally you should remove the PLASTIGAUGE stripe with a clean oily cloth or industrial de-greasing solvent, but users may be assured that any PLASTIGAUGE left behind is oil soluble and cannot harm the engine in any way.
