Use of spray lubricant or liquid soap will aid in the installation of rubber parts.

Compressor belly is rounded and can be “rocked” on the belly support. It is easiest to install one spring grommet at a time. Start with the most difficult to access compressor mounting leg and work in a crisscross pattern from back to front.

Compressor mounting bolts should be tightened down so that the metal sleeve is secured fast to the chassis base and bolt head. Before securing the final bolt, make sure that the wooden block or material supporting the belly of the compressor has been removed.
