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 12.6 lb-ft (17
N-m) of torque. Reinstall coupling guard with provided fasteners.

– COUPLING ELEMENT
4. For hub-to-shaft interference fit hubs, main drive motor removal is necessary:
Remove coupling guard by removing fasteners
Remove coupling ventilation shroud by removing fasteners
Drain oil entrained in discharge manifold by placing appropriate collection pan underneath elbow
segment and removing the 1/4” npt plug threaded tangent to said elbow. Proceed then to drop the
flanged of the discharge manifold by removing the bolts from compressor flange.
Remove the following various lines connecting the package to the compressor. Make sure to
identify each line and matching [compressor-side connection] for proper reassembly
– you may
also refer to the Parts List 13-18-505 for more details:
Oil Injection hoses (one (1) base flow, two (2) solenoid valve flow)
Bearing oil lubrication tube
Drain nylon tube
Inlet poppet valve pneumatic signal hose
Air filter discharge hose
Engage jack screws [built into base frame] until they make solid contact with the [front side] motor
mounting pads.
Remove vertical support wall by removing fasteners and slide side-ways through door opening.
Remove four bolts securing (main motor) rear support to base frame.
Engage jack screw [built into base frame] until it makes solid contact with the compressor/motor
adaptor housing.
Remove eight (8) bolts/nut/washer combos securing motor to adaptor housing.
Lift/Pull away compressor and main motor adaptor from motor 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. It is highly recommended that the coupling element be replaced at this time.
Re-assemble main motor and related components in reverse order.
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 within 1.38/1.50 in (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 setscrews (M10 size) and tighten to 12.6 lb-ft (17 N-
m) of torque. Reinstall coupling guard and coupling ventilation shroud with provided fasteners.
