C. Engine 603 with pot-type generator
Preliminary work:
Poly V-belt slackened (13-3420) .
Front noise encapsulation removed (94-5310).
| Quiescent current retention unit | disconnect, connect. |
| Ground cable at battery | disconnect, connect. |
| Ring (1) of radiator shroud | slacken, attach. |
| Collar nut (2) | unscrew, screw on, tightening torque 70 Nm. Use hexagon socket bit (8 mm) with reversible ratchet to hold shaft (3). |
| Poly V-belt pulley (4) with | take off, fit on. |
| spacer disc (5) | |
| Supporting disc (6) | take off, fit on. |
| Fan wheel (7) | take off, fit on. |
The poly V-belt pulley (4) and the fan wheel (7) are subjected to very different stresses. The level of these stresses depends primarily on the driving conditions. For this reason, when reconditioning generators on vehicles which have driven more than 100,000 km, at the same time also replace the poly V-belt pulley (4) and the fan wheel (7).
