3.11 TRAILER JACK (SOLID WHEELS)
Installation
1. Place the jack against the trailer tongue and position
the mounting straps on the opposite side of the
tongue. Place the straps so the flat side is against
the tongue.
2. Install the bolts through the bracket and straps.
Position the jack so the top bolts rest directly on the
top of the tongue and the bottom bolts are as close
to the tongue as possible. The gap between the
mounting bolts and the trailer tongue is not to
exceed 1/16" (1.6 mm).
3. Secure the bolts in place with the locknuts. Torque
the nuts to 25 ft.lbs. (34 Nm).
4. Check for clearance of handle swing, trailer light
cables, and coupler clearance.
Operation
NOTE: To avoid damaging the handle while trailering in the
horizontal position, secure the handle to the jack
with a bungee cord or rope.
The jack is designed to be swiveled into a horizontal or
storage position. In both the vertical and horizontal posi-
tions, the plunger must be securely positioned in the mat-
ing hole in the mounting bracket. To place the jack into the
horizontal position, allow about 2" (5 cm) of ground clear-
ance beneath the wheels. Pull the plunger pin out of the
opening and swivel the jack. Rotate either left or right until
the plunger pin snaps into the proper mounting bracket
hole.
Maintenance
The internal gearing and bearings of the jack must be kept
lubricated. Using a needle nose applicator, pump a small
amount of automotive grease through the lubrication
opening. The lubrication opening can be found on the
side of the jack tube, right above the support plate. Rotate
the jack handle to distribute the grease evenly. Lightly
grease the inner tube of the jack using the same type of
grease. A light weight oil must be applied to the handle
unit at both sides of the tube. The axle bolt and nut
assembly of the caster wheel must also be lubricated with
the same light weight oil.
