Removal
- Using Clutch Disc Wrench (J-41260), remove clutch plate bolt. Using Clutch Disc Puller (J-38874), remove clutch plate. Insert clutch disc puller pins into clutch disc holes. Rotate holder clockwise to lock it into clutch disc. Tighten clutch disc puller center bolt and remove clutch disc plate and shims. Remove snap ring. (Scheme 1)
- Using a puller, remove center pulley. Position puller claws on the edge of pulley to prevent pulley groove from being deformed. Remove clutch coil harness clip, coil external snap ring and clutch coil.
Installation
- Ensure clutch disc and pulley contact surfaces are clean and free of excessive grooving and/or damage due to excessive heat. Check clutch coil for loose connection or cracked insulation. Replace clutch disc and pulley as a set and/or clutch coil, if necessary.
- Align clutch coil pin with hole in compressor front head. Install clutch coil harness clip. Using hand press, install pulley and snap ring. Install original shim(s) and clutch disc. Using Clutch Disc Wrench (J-41260), install and tighten center bolt to 10 ft. lbs. (14 N.m). Ensure pulley turns smoothly.
- Use a feeler gauge to check clearance between clutch plate and pulley. Clearance should be .012-.024" (.30-.60 mm). If clearance is incorrect, add or remove shims as necessary.
Scheme 1
- Using clutch holder, remove clutch plate bolt. Using an 8-mm bolt threaded into clutch plate, remove clutch plate and shim(s). (Scheme 2)
- Remove snap ring and pulley assembly. Install Shaft Protector (49 UN01 045) over shaft seal opening. Use a 2-jaw puller to remove clutch coil from compressor.
- Ensure clutch coil mounting surface is clean. Use coil installer and 2-jaw puller engaged to rear side of compressor front mounts to press coil into place.
- Install pulley assembly. Install snap ring with bevel side of snap ring facing out. Install shim(s) and clutch plate. Install a new clutch plate bolt and tighten to 97-115 INCH lbs. (11-13 N.m).
- Use a feeler gauge to check clearance between clutch plate and pulley. Clearance should be .014-.033" (.35-.84 mm). If clearance is incorrect, add or remove shims as necessary.
- Using clutch holder, remove clutch plate bolt. Using an 8-mm bolt threaded into clutch plate, remove clutch plate and shim(s). (Scheme 2)
- Remove shaft seal felt. Thoroughly clean seal area of compressor. Remove shaft seal snap ring. Position shaft seal remover over compressor shaft.
- Push shaft seal remover downward against seal. Ensure end of shaft seal remover is engaged with inside of seal. Rotate shaft seal remover clockwise to expand remover tip inside seal. Pull shaft seal from compressor.
- Lubricate shaft seal protector and shaft seal with refrigerant oil. Install shaft seal on shaft seal protector so lip seal is toward compressor (large end of shaft seal protector).
- Install shaft seal protector on compressor shaft. Using shaft seal installer, push shaft seal down seal protector until seal is seated.
- Remove shaft seal installer and protector. Install a new shaft seal snap ring and shaft seal felt. Install shim(s) and clutch plate. Install a new clutch plate bolt and tighten to 97-115 INCH lbs. (11-13 N.m).
- Use a feeler gauge to check clearance between clutch plate and pulley. Clearance should be .014-.033" (.35-.84 mm). If clearance is incorrect, add or remove shims as necessary.
Scheme 2
- Hold clutch disc using Clutch Disc Wrench (J-33939) and remove center bolt. Using Clutch Disc Puller (J-33939), remove clutch disc and adjustment shim(s).
- Remove snap ring. Remove pulley using Pilot (J-38424) and universal puller. Remove clutch coil. (Scheme 3)or (Scheme 4).
- Ensure coil lead is installed in original position. Install and tighten coil screws. Press pulley onto compressor using Pulley Installer (J-33940). Install snap ring and adjustment shim(s).
- Install clutch disc and tighten center bolt to 11-13 ft. lbs. (15-18 N.m). Using feeler gauge, ensure clearance between clutch disc and pulley is .012-.024" (.30-.60 mm). If clearance is incorrect, add or remove shim(s) as necessary. Break-in clutch by engaging and disengaging clutch 30 times.
