5. Remove the dust cap from both of the hydraulic
angle cylinder ports and attach one 7/16" male
ORB adapter to each port. Connect the straight
end of one 1/4" x 25" hydraulic hose (B60426)
to each angle cylinder adapter. Be careful not to
overtighten the hose connections. Route both
hoses through the A-frame access holes, near the
angle cylinder mount brackets. Tighten fi ttings and
hoses according to the torque chart.
6. Position each angle cylinder with the rod
end of the cylinder in the pivot beam. Secure
the cylinders to the pivot beam with a
3/4" x 3-7/16" clevis pin and a 1/4" x 1-1/2" cotter
pin. Extend each cylinder rod until the cylinder
base mounting hole aligns with the hole on the
A-frame angle cylinder bracket. Insert another
clevis pin and secure it with a cotter pin.

7. Remove the plastic dust caps from the hydraulic
lift cylinder ports. Attach one 7/16" 90° adjustable
elbow ORB adapter to the extend port (base end)
and one 7/16" male ORB connector adapter to
the retract port (rod end). Connect the straight
end of the 1/4" x 13-1/2" hydraulic hose (B60432)
to the rod end adapter. Tighten fi ttings and hose
according to the torque chart.
8. Position the lift cylinder in the channel opening
under the A-frame. Route the 13-1/2" rod end
hose through the front (closest to the pivot beam)
2" diameter hole in the A-frame. The lift cylinder
base end hole should be aligned with the holes on
either side of the channel. Secure the lift cylinder
to the A-frame using a 5/8" x 5-3/4" clevis pin and
one 1/4" x 1-1/2" cotter pin. Use the access hole in
the A-frame, located on the driver's side, to install
the clevis pin. Connect the 1/4" x 10" hydraulic
hose (B60293) to the base end adapter. Tighten
hose according to the torque chart.
