Hydraulic Attachment
NOTE: The SAE O-RING and JIC 37 (deg) flare
type hose connections do not require sealant for
reconnecting. They do not require high torque for
a good seal.
IMPORTANT: When using sealant on pipe
threads the friction between the threads is re-
duced; therefore, be certain not to over tighten
which may cause damage to a valve, cylinder
port or fitting.
See Figure 3:
Figure 3
Hydraulic and Wiring Attachment
17990
Attach the relief valve (6) to the mounting bracket
on the rear cross tube of the tongue with two 5/16
x 2 3/4 inch long bolts (7), lock washers (8), and
nuts (9). Connect the two hydraulic hoses (10)
that are routed through the tongue to the relief
valve with one connecting to the upper port on the
left hand side and the other connecting to the low-
er port on the right hand side.
Connect the 1/2 inch hose (11) leading from the
depth stop valve, to the lower left hand port of the
pressure relief valve (6) located on the tongue.
Connect the 1/2 inch hose (12) leading from the
rod end of the right hand transport cylinder to the
upper right hand port of the same valve.
Wiring Attachment
Refer to Figure 3. Route the main lead of the light
wiring harness (13) through the tongue and con-
nect it to the wishbone harness (14) that is
connected to the lights on the drill.
Clutch Linkage
Figure 4
Clutch Linkage Attachment
14042
See Figure 4. The clutch to gauge wheel arm link-
age (1) is left un-attached for shipping purposes.
Once the unit has been set on the ground, it may
be attached to the gauge wheel arm. Make sure
that the clutch cam plate (4) is rotated to the bot-
tom of center as shown before the arm linkage is
connected so that the cam rotates down and rear-
ward when the drill is raised. Remove the nylock
nut (2) from the arm linkage. Insert arm linkage
through the tab (3) on the gauge wheel arm and
reinstall the nut. Do not cinch the nut down tight,
the linkage must rotate freely.
