EL-740 Air Compressor Inspection – Crankshaft Bearing Caps

1. Examine front and rear bearing caps (base mount). Replace if cracked, or if the gasket surfaces have been defaced.

2. On air compressors with a sleeve-type rear bearing, check the inside diameter of the rear bearing. If the dimensional limits of the rear bearings exceed the limits stated in the “Specifications” section or is damaged, the bearing cap must be replaced.
