TORSION BAR REPLACEMENT (Contd)
INSTALLATION
NOTE
Removal and installation of right and left torsion bars are
performed the same way. Right side is shown.
Apply grease to O-ring and splines of torsion bar prior to
installation.
1.
Install new O-ring (15) and lube fitting (16) on flange (12) of torsion bar housing (11).
NOTE
Perform step 2 if spacer was removed from torsion bar.
2.
Install spacer (18) on torsion bar (17) until seated.
3.
Slide torsion bar (17) in torsion bar housing (11) and install spacer(s) (10), washer (9), washer (8),
and screw (7) on torsion bar (17) and torsion bar housing (11). Do not tighten screw (7) until
screw (23) is installed.
4.
Align notch in washer (9) with hole in torsion bar housing (11), apply sealing compound to threads
of screw (23) and install screw (23) on washer (9) and torsion bar housing (11). Tighten screws (7)
and (23).
NOTE
If torsion bar lever was not marked or torsion bar was broken
when removed, perform steps 5 through 10 and step 14 to pre-set
torsion bar lever and turnbuckle for installation.
5.
Install torsion bar housing (11) on outer ponton (1) with one screw (14).
6.
Position pre-adjusting tool (25), flat edge against deck over-hang (24), on outer ponton (1).
NOTE
Lube fitting on torsion bar housing must face upper corner of
outer ponton.
7.
Install torsion bar lever (22) on torsion bar (17) and check alignment of lever (22) with pre-
adjusting tool (25).
8.
If necessary, adjust position of lever (22) by moving lever (22) one tooth up or down on torsion bar
spline. This will move lever (22) 10 degrees.
9.
If necessary, remove screw (14) and turn torsion bar housing (11) one screw position up or down.
This will move lever (22) 45 degrees.
10.
Mark position of torsion bar lever (22) and torsion bar housing (11) on outer ponton (1) and slide
torsion bar housing (11) part way out of outer ponton (1).
11.
Apply unlike metal compound to mating surfaces of outer ponton (1) and flange (12), align marks,
and install torsion bar housing (11) on outer ponton (1) with eight washers (13) and screws (14).
12.
Align marks, and install torsion bar lever (22) on torsion bar (17) with washer (21), washer (20),
and screw (19).
13.
If a new turnbuckle (2) or cleves ends (6) are being replaced, remove two screws (3), washers (4),
and pins (5) from turnbuckle (2) and perform step 14 to pre-set turnbuckle (2)
