Removal
- Use a M8 x 40 mm bolt with 7/32" of the threaded end machined to a cone shape to remove clutch plate.
- Remove snap ring and shim(s) from shaft. Tap pulley off shaft with plastic hammer. If pulley cannot be removed by hand, use a puller. Remove snap ring, bearing, and seal (if equipped) from pulley. (Scheme 1) Remove screw for clutch coil lead. Remove snap ring and clutch coil.
Installation
To install, reverse removal procedure. Ensure snap rings are installed with beveled side facing out. Tighten shaft bolt (or nut) to 11-15 ft. lbs. (15-20 N.m). Ensure air gap between clutch plate and pulley is .016-.028" (.41-.71 mm). If air gap is incorrect, add or remove shim(s) as necessary.
Note. On some compressors, it is necessary to use a dial indicator on clutch plate to check air gap. Energize clutch coil and zero dial indicator. De-energize clutch coil and measure air gap. Ensure air gap is as specified.
Scheme 1
- Remove clutch plate and pulley. Remove shim(s) from shaft. Remove clutch coil if necessary. Remove felt and felt retainer (if equipped). (Scheme 1) Place shaft key remover on shaft and turn to remove key.
- Remove seal plate snap ring. Engage plate remover on seal plate, and pull up to remove seal plate. Engage shaft seal remover/installer to shaft seal, and pull up to remove shaft seal from front housing.
- Apply clean refrigerant oil to compressor housing bore. Lubricate shaft seal with refrigerant oil and install in front housing. Lubricate seal plate and install in front housing.
- Install shaft key, snap ring, felt retainer and felt. With clutch plate installed, ensure air gap between clutch plate and pulley is .014-.026" (.35-.65 mm). If air gap is incorrect, add or remove shim(s) as necessary.
