The fRoNT ANd ReAR bolsTeR fRAMes
1. Insert the Lock Collar (A) into the opening provided on the Rear
Bolster Pipe Frame (C). The end of the Front Bolster Pipe (B)
should slide into the Rear Bolster Frame (C). Line up the holes in
the Lock Collar and bolt together using one 3/4" x 7" bolt (D) and
one 3/4" nylon locknut (E).
2. Mount the Tire and Rim (F) to the front and rear bolster using forty
3/4" Flanged Wheel Nuts (G) (650 Bu. ). For 550 Bu. mount use
32 5/8" Flanged Wheel Nuts (G). Torque Wheel Nuts to 400 ft*lb
(650 Bu.). For 550 Bu., torque to 225 ft*lb.
TIGHTEN ALL BOLTS (SEE TORQUE CHART ON PAGE 11.)
INsTAllING The ToNGue ANd
The lIfT AssIsT sPRING
1. Mount the Tongue (H) onto the Pivot Arm (R), fasten together using
one 1-1/2" Dia. x 9" bolt (J) and one 1-1/2" nut (K). Tighten just
enough to take out all slack and hold nut in place using one 1/4" x
1/4" socket set screw (L).
2. Insert 5/8"-11 x 9" bolt through Tongue as shown using two 5/8"
Flatwashers (W), and one 5/8" nylon insert locknut (X). Tighten
bolt until all slack is removed between the tongue and pivot arm
(R). Do not over tighten, the tongue should still move freely. Raise
the tongue and support on a stand.
3. Mount the Lift Assist Plate (Q) onto the top of the Pivot Arm (R) using
two 5/8"-11 x 1-3/4" bolts (S) and two 5/8" nylon insert locknuts
(T).
4. Attach the Lift Assist Springs (M) to the Lift Assist Plate (Q)
by threading the two 1/2"-13 x 6" full thread bolts (N) with 1/2"
lockwasher (O) into the threaded insert in the springs (M). Tighten
the bolts to remove any slack. Remove the stand and adjust the
tongue height using the two 1/2" x 6" bolts.
5. Adjustment of the 5/8" x 2 1/2" bolts (Y) on the Pivot Arm (R) should
be preset to not overturn. If adjustment is required, do so once box
is mounted on running gear. Be careful that tires will not turn into
the box frame.
AdjusTING The TIe Rods foR AlIGNMeNT
1. Alignment is present at the factory. To check alignment, the Tie
Rods (P) should be adjusted to have 1/4" to 3/8" toe in (measured
at tire bead edge of rim). When this adjustment is made, the tongue
must be aligned with the round pipe on the front bolster. Be sure
both wheels toe in equally.
