Checking and adjusting gap
- Measure gap between belt pulley and clutch plate using depth gauge -C- at 3 points. This is measurement -1-.
- Apply 12V DC to magnetic coil. Positive B+ voltage to single pin connector -A- Ground (-) to A/C compressor housing -B
- Measure gap again between pulley and clutch disc measured with gauge -C-. This is measurement -2-. Difference between two measurements -1- and -2- must be: 0.4 to 0.6 mm (0.016 to 0.024 in.)
Note. The gap must lie within tolerances around the entire circumference. Gap can also be measured with compressor installed. If gap dimension lies outside of the permissible range, remove clutch disc and adjust gap dimension by removing or inserting spacer.
