Vibration Analysis - Engine Balance

Placing an electronic vibration analyser sensor onto the underside of the engine oil sump along the FRONT and the REAR edge allows for a determination to be made, which will help to narrow down the cause of the disturbance.

The clutch pressure plate and the engine flywheel are marked for proper indexing of the heavy-spot of one to the light-spot of the other. Improper indexing of the pressure plate to the flywheel can produce a disturbance.

An engine flywheel that is loose at the engine crankshaft or that is cracked, damaged and/or missing balance weights; and/or a clutch pressure plate and clutch driven plate that has loose springs, cracks, warpage, damage and/or missing balance weights - can produce a disturbance when their mass is combined.
