Clutch Coil: Installation
- To install, reverse removal procedure. Use NEW snap rings. Ensure snap rings are installed with beveled side facing out and fully seated in snap ring groove. Install clutch coil with wire facing downward. Apply thread lock to compressor shaft bolt. Tighten shaft bolt to 117 INCH lbs. (13 N.m).
- On Acura and Honda, ensure air gap between clutch plate and pulley is 0.014-0.026" (0.36-0.66 mm). If air gap is incorrect, add or remove shim(s) as necessary.
To install, reverse removal procedure. Tighten shaft bolt to 97-142 INCH lbs. (11-16 N.m). Ensure pulley-to-clutch plate clearance is 0.014-0.025" (0.35-0.64 mm). If clearance is incorrect, add or remove shim(s) as necessary.
- To install, reverse removal procedure. Ensure clutch coil pin is aligned with hole in compressor housing. Ensure clutch coil lead is positioned properly. Ensure snap rings are installed with beveled side facing out. Tighten shaft bolt to 10-13 ft. lbs. (14-17 N.m).
- Check air gap between clutch plate and pulley. Position dial indicator on clutch plate. Energize clutch coil and zero dial indicator. De-energize clutch coil and measure air gap (clutch plate movement). Ensure air gap between clutch plate and pulley is 0.014-0.026" (0.35-0.65 mm). If air gap is incorrect, add or remove shim(s) as necessary. Ensure pulley rotates freely.
- To install, reverse removal procedure. Align lug on clutch coil with hole in front housing of compressor. Install snap ring with chamfered side facing out. Position pulley squarely over coil. Ensure compressor boss and inside area of pulley bearing are clean and free of foreign material. Using Pulley Installer (09991-06010), press pulley onto compressor boss. Install pulley snap ring.
- Install shim(s). Using feeler gauge, ensure air gap between clutch plate and pulley is 0.012-0.020" (0.30-0.50 mm). If air gap is incorrect, add or remove shim(s) as necessary. Hold clutch plate and tighten compressor shaft nut to 11 ft. lbs. (14 N.m).
- To install, reverse removal procedure. Ensure clutch coil is positioned correctly. Ensure new snap rings are installed with beveled side facing out. On Lexus and Toyota, tighten clutch plate center bolt to 115 INCH lbs. (13 N.m). On all other models, tighten shaft bolt (or nut) to 11-15 ft. lbs. (15-20 N.m).
- On Lexus and Toyota, ensure air gap between clutch plate and pulley is 0.014-0.026" (0.35-0.65 mm). On all other models, ensure air gap between clutch plate and pulley is 0.016-0.024" (0.41-0.61 mm). On all models, if air gap is incorrect, add or remove shim(s) as necessary.
NOTE:
Clutch clearance on Lexus LX 430 is 0.012-0.022" (0.30-0.55 mm).
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.
