Shaft Seal: Installation

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 97-123 INCH lbs. (11-14 N.m).
Use a feeler gauge to check air gap between clutch plate and pulley at 3 places around pulley. Ensure air gap is 0.014-0.033" (0.35-0.84 mm). If air gap is incorrect, add or remove shims as necessary.
