BT77.37-P-0001-01A | Main valve on hydraulic unit discontinued | |
MODEL 124.### 1B up to 837705 up to 25.8.92,
129.### 1F up to 083890 up to 29.4.93
Modification notes
With the introduction of the modified hydraulic unit A7/5
the main valve A/5y1 has been discontinued.
The previous hydraulic unit is no longer supplied as a replacement part.
When replacing the hydraulic unit on model 129, the control module must be replaced as well.
After the deletion of the main valve, both the soft top bow and the top well lid are pulled down slightly when the roll bar is actuated (with the soft top or roll bar switch) because the hydraulic cylinders for the catches are pressurized (not a fault but current production configuration).
