Next, remove both of the plastic dust caps from the HYDRAULIC LIFT
CYLINDER ports. Attach one 7/16"-20 x 7/16"-20 45˚ ADJUSTABLE
ELBOW O.R.B. ADAPTER to the driver’s side port and one 7/16"-20 x
7/16"-20 MALE O.R.B. CONNECTOR ADAPTER to the passenger’s side
port. Once the adapters have been installed on the cylinder, connect the
HYDRAULIC HOSES. The 45˚ adapter on the driver’s side of the cylinder
receives a 1/4" x 17" hose identified by a label containing the number 3.
Connect the 45˚ angle on the hose to the hydraulic adapter on the cylinder.
The male connector adapter on the passenger’s side of the cylinder
receives a 1/4" x 15" hose identified by a label containing the number 4.
Tighten the 45˚ end of the hose to the hydraulic adapter on the cylinder.

Next, use a screwdriver to pull the hydraulic cylinder rod out from its
base. Place one 1-1/4" diameter washer over the cylinder rod, followed
by the 12" COMPRESSION SPRING and another 1-1/4" washer. Compress
the coils approximately 2" and clamp the spring and washers in place
using a pair of vise grips. This will help facilitate the draw latch installation.
7.
Begin the draw latch installation by first removing both of the 6" extension
springs on the latch. Proceed to remove both 1/2"-13 x 2" bolts with
washers and spacers from the DRAW LATCH BOLT MOUNT PIN. Once
the springs and hardware have been removed, loosen the SET SCREW
on the OUTER DRAW LATCH PLATE using a 1/8" Allen wrench and
remove the draw latch bolt mount pin from the assembly.
Next, remove the 1" x 4-1/2" DRAW LATCH MOUNT PIN from the
assembly. By removing this pin, the INNER DRAW LATCH PLATES can
swing free. Proceed to remove the 3/4" x 2-1/2" INNER DRAW LATCH
PLATE CYLINDER MOUNT PIN. Position the plates on either side of the

Draw Latch Assembly
The draw latch consists of a series of intercon-
nected plates and pins that attach to the A-frame
and the hydraulic cylinder that raises and lowers
the plow. The draw latch is also the most difficult
component to install on the entire plow and may
require the help of a second technician.
