The compressor unit and motor are rigidly connected via a mounting adapter housing.

This arrangement makes coupling alignment unnecessary.

The coupling is a jaw type in shear. If the elastomeric element requires replacement due to wear or breakage, order replacement element no. 02250152-669, and follow the following steps:

1. Remove the protective grill from the adapter housing.

2. Loosen the retaining screw located on the outer sleeve. Slide the sleeve to one side, exposing the coupling element.

3. Unwrap the coupling element from the coupling jaws.

4. Install the new element by wrapping it around the jaws, engaging the cogs on the element into the jaws.

5. Reinstall the outer sleeve and torque the securing screws to 10 in·lb (1.13 N·m). Install the protective grill.;
