| 122-A6R3Q-05 | 2017-07-19. Service bulletin. POWER TRAIN:DRIVELINE; POWER TRAIN:DRIVELINE:DRIVESHAFT. "Concern: Replacing Hardy disc on the cardan shaft during repairs Notes: Previously, the Hardy disc (± Figure 1) was not available separately, and the entire cardan shaft had to be replaced. In order to improve the serviceability of these vehicles, we have now made the Hardy disc available as a separate part and it can be replaced independently of the cardan shaft, if required." |
