Alternator Mount, Adjusting
Alternator mount, adjustingIf alternator mount is loose, with a consequent rattling noise, the cause can be the elimination of the spring washer under each bracket mounting bolt. The mounting bolts may only partly touch the uneven and rough surface of the cast iron bracket, causing the preload force to be insufficient even with correctly applied torque.
To correct,
- install spring washer, Part No. N012 24 111, on each bracket mounting bolt
- install bolts and torque to 22 Nm (16 ft lb)
Note: Spring washers are now installed on cars beginning with January, 1982 Vanagon production (from VIN 25CH089151).
Mounting belts, tightening
If alternator mounting bolts become loose, follow this procedure..
Waterboxer
- replace old bolts with new bolts of higher strength (New bolt P/N N14 400.4)
- re-torque new bolt to higher torque specification
Diesel motor
- re-torque old bolts
Torque specification:
Waterboxer 24.0 Nm (18 ft lb)
Diesel motor 28.0 - 33.0 Nm (21.0 - 24.0 ft lb)
