Removal and installation the electromagnetic clutch
When loosening the central bolt, hold the clutch disc with a special key (KV99231260 for DKV-11D/14D or KV99106700 for CR-14).
The material is based on data from the portal [NISSANBOOK]
For DKV-11D/14D compressors, a special tool KV99232340 is required to remove the clutch disc. Insert the pins of the tool into the clutch disc and turn the tool clockwise to fix it on the disc. Then tighten the bolt, inserting a screwdriver between the two pins to prevent the disc from turning. After removing the disc, remove the washers from the shaft or disc.
In the CR-14 compressor, the disk can be removed without any special tools.
Any suitable puller can be used to remove the pulley.
To prevent deformation of the pulley groove, the puller jaws must be installed in the groove (for single groove pulley) or under the edge of the pulley (for multi-groove pulley).
Before installation, clean the contact surfaces of the clutch disc and pulley with solvent.
When installing the coil, its pins must be aligned with the holes in the compressor body.
The pulley is installed using a mandrel (KV99234330 for DKV-11D/14D or KV99106800 for CR-14) and the press (for DKV-11D/14D) or a plastic hammer (for CR-14).
After assembly, measure the gap between the clutch disc and the pulley along the entire circumference. It should be within 0.3-0.6 mm. If necessary, adjust the gap by selecting washers.
Running in the clutch
After replacing the compressor clutch, it is necessary to run it in by turning it on and off about thirty times. This increases the transmitted torque.
