· Remove coupling guard by removing four bolts
· Remove two bolt/nut/washer combos securing [main motor] rear support to base frame.
· Insert temporary support between adaptor casting and support frame (e.g., wood beam) to
maintain compressor level when main motor is retrieved.
· Remove four bolts securing main motor to adaptor.
· Slide/Pull main motor away from adaptor until coupling hubs separate and allow removal of
spider.
· Inspect coupling element for signs of wear and tear such as indentations, cracks, deformation,
extrusions, etc. Replace, if necessary.
· Re-assemble main motor and cooling fan components in reverse order of disassembly.
· After engaging each hub on the matching recesses of the coupling element, check that the gap
between the hub flats (see dimension "E" on Figure 8-2) is no less than 1.38/1.50 inches (35/38
mm). A smaller gap will produce abnormal wear of the element by friction and excessive thermal
expansion – the latter could cause compressor damage by axially displacing the input shaft.
Make sure that keys are in proper alignment with key-ways on hubs.
· Apply a thread-locking compound to the hub set screws (M10 size) and tighten to 150.5 lb-in (17
Nm) of torque. Reinstall coupling guard with provided fasteners.
