Compressor Servicing: Removal & Installation Mitsubishi Eclipse II

Removal

1. On Diamante Wagon, use a M8 x 40 mm bolt with 7/32" of the threaded end machined to a cone shape to remove clutch plate. On all other models, remove nut and clutch plate using Clutch Plate Holder/Remover (J-41384).
2. On all models, 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)or (Scheme 2). 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 .020" (.50 mm) on Diamante Wagon; .016-.028" (.41-.71 mm) on all others. 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.

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)or (Scheme 2). Place shaft key remover on shaft and turn to remove key.
2. 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.

1. 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.
2. Install shaft key, snap ring, felt retainer and felt. With clutch plate installed, ensure air gap between clutch plate and pulley is .020" (.50 mm) on Diamante Wagon; .014-.026" (.35-.65 mm) on all others. If air gap is incorrect, add or remove shim(s) as necessary.

1. Remove drive belt pulley (if equipped). Hold clutch plate using Pliers (MB991367) and Bolts (MB991386). Use a ratchet and socket to remove clutch hub nut.
2. Remove clutch plate. (Scheme 3)or (Scheme 4). Remove snap ring with internal snap ring pliers. Remove clutch hub (rotor). Remove snap ring and clutch coil.
3. Using an awl, remove bearing cover and retainer. Using Bearing Remover (MB991456), engage bearing grooves. Place base of bearing remover over remover arms and tighten nut.
4. Tighten bearing remover bolt to withdraw bearing from compressor. Engage grooves of Shaft Seal Remover/Installer (MB991458) and pull straight up on shaft seal.

1. To install shaft seal, ensure front housing is free of foreign objects. Lubricate Shaft Seal Protector (MB991459) and place over compressor shaft. Lubricate shaft seal and install using shaft seal remover/installer. Remove shaft seal protector.
2. Using a 21-mm socket or Drift (MB991301), carefully press bearing onto compressor shaft. Install clutch coil so that alignment pin is engaged. Install clutch coil snap ring with tapered side facing out.
3. Align armature plate with crankshaft spline. Tighten shaft nut to 12 ft. lbs. (16 N.m). Using feeler gauge, ensure clearance between pressure plate and pulley is .016-.024" (0.4-0.6 mm). If clearance is incorrect, add or remove shim(s) as necessary.

Note. If shaft seal leaks, replace compressor.
