### Equipment Driveshaft

#### PRECAUTIONS

1. The flexible coupling is not to be disassembled. Do not re-use a flexible coupling which has been disassembled.

   Fig. 1: The couplings are on each end of the shaft, DO NOT disassemble them

2. The driveshaft must be installed in a straight line without forcing it. The coupling is made out of rubber, so it can easily bend out of shape. When performing service related to the driveshaft, observe the following:
   - Do not disconnect the rear end of the driveshaft from the engine and the leave the shaft resting at an angle for a long period. When leaving the driveshaft disconnected for long periods, support it with a sling so that it is horizontal, in a straight line with the engine.

     Fig. 2: Always use a sling to support the shaft if being left unattached for long periods of time

   - Store the driveshaft in a straight line without bending it.

   - When installing the driveshaft, visually check that the flexible coupling is not twisted or squeezed out of shape. If the coupling is out of shape, disconnect it and install it again.

     Fig. 4: When installing, make sure the shaft is not out of shape or twisted

   - When installing the equipment driveshaft and drive housing, measure the installation angle of the driveshaft in front of and behind the flexible coupling. If the difference in the angle between each section is 2°or more, correct the installation angle by adjusting the position of the No. 3 equipment drive housing stay and No. 2 equipment drive housing insulator. The angle gauge is 09370–50010 or equivalent.

     Fig. 5: Use an angle gage to measure the installation angle of the driveshaft in the front and behind the coupling

   - For vehicle which have been in a serious accident, also check the body dimensions.
3. There are ground straps between the equipment drive housing and body, and between the alternator and negative battery terminal. After completing the operation, always check that the ground straps are firmly attached.

   Fig. 6: Check all ground straps to see if they are all secure

4. When rotating the driveshaft or engine by hand, this can be done by inserting a service bolt 12mm damper and 1.25mm pitch with a nut into the screw hole at the end of the driveshaft. After doing the operation, do forget to remove the service bolt and nut. If the service bolt is left installed, the bolt head may be hit and damage the cooling fan.
