7. Insert the quill shaft with bearing
8. During the mounting operation, apply a film layer of grease on the front and rear faces of the gasket, then attach it between the main transmission and PTO Plate connection surfaces. Mount the Studs on the Transmission using suitable torque value. Please also apply threadlocker glue on studs to prevent loosening due to vibration.
9. Once Detroit PTO mounting has been completed, the connection components need to be inspected just in case.
10. The main transmission oil is then poured back into it from the container it had been put into, and then oil plug is fastened (If the oil has expired, new oil must be added).
11. Detroit PTO Engaging System will be assembled. (This can be air hoses, control cable&lever or electric wiring, depending on control Type)
12. For DT12-OC (DT12-OHE/-OV, G320-12) DT12-DC (DT12-DHE/-DV, G271-12)/ DT12-OD (DT12-OVX, G340-12) Lube line should be be assembled.

14. In case the hydraulic pump, which will be installed on the PTO, is 40 lbs or heavier and the length is 12″ or longer, the pump must be supported by a bracket to avoid damaging the PTO. Otherwise, the PTO will carry all the load and may get damaged over time.
Aluminum Body Detroit PTO Installation Picture
✓ PTO temperature might sometimes have a negative influence, and the temperature needs to be lowered in case of overheating.
✓ More frequent oil changes must be conducted in heavy-duty operations.
✓ Where the PTO is side-mounted, make sure to inspect the backlash.
✓ Where the PTO is rear-mounted and used in heavy-duty operations, extra lubrication must be provided.
