before attempting any of the following procedures.
1. Install stroke control and stroke control cover on
master cylinders. Replace cylinder yokes. Adjust
cylinder extended length of all cylinders to measure
28-1/4" from hole center to hole center. Tighten lock
bolt or set screw to lock yoke in place.

Always adjust the slave cylinder extended length to
measure the same as the master cylinder to allow the
unit to operate level in the field
(See Table 3-1 and
Figure 3-6.)

up, using clevis pin and cotter pins. Connect rod to
gauge wheel arm or rockshaft using extended pin
and 1/4 hair pins.
3. Install the slave cylinders on the wing frame ports up,
using clevis pin and cotter pins. Connect rod to
gauge wheel arm or rockshaft using extended pin
and 1/4 hair pins.
4. Install 90
o
adapters into base and rod end of each lift
cylinder.
5. Install two 90
o
adapters in ports #2 and #4 and
adapter in port #3 of flow divider valve. Secure flow
divider valve to flow divider mounting bracket using

hex lock nuts. Install check valves on frame using
3/8-16 x 1-3/4 hex head cap screws and split lock
washers.

Mount double pilot check valves so that the ports V1
and V2 are facing the flow divider valve with V1 port
behind the V2 port. Install hose A in V1 ports of each
check valve and connect to 90
o
adapters on the flow
divider valve. Install hose a into V2 port of each
check valve. Connect together hose A with tee
adapter.
6. Screw check valve w/ orifice into port C1 of check
valves with arrow pointing away from port C1.
7. Screw adapters into ports C2, V1, and V2 of check
valves. Use hose C to connect check valve w/ orifice
to base port of master cylinders.
8. Connect hose B from adapter in C2 port of check
valves to the rod end of slave cylinders.
9. Connect hose D from the base end of slave cylinders
to the rod end of master cylinders.
10. Install one hose E from tee adapter to coupler. Install
other hose E from adapter in port #3 in flow divider
valve to coupler.
