Removal (Fig. 106)
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
2. Topreventcontaminationofhydraulicsystemduring
manifold removal, thoroughly clean exterior of PTO
manifold and fittings.
3. Disconnect wire harness connector from the sole-
noid valve coil on the PTO manifold.
4. Disconnect hydraulic lines from manifold and put

disconnected hydraulic lines for proper installation.
5. Remove PTO manifold from the frame using Figure
106 as a guide.
NOTE: The upper cap screw on the right side PTO
manifold also secures the ground cable and has a lock
washer to ensure a good grounding path. Make sure
that lock washer is retrieved when removing RH PTO
manifold from frame.
6. Ifhydraulic fittings are to be removed from manifold,

ifold openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
