Assembly
1. If removed, install brake support, (13, Figure 3-
5) to the spindle (17).
2. Align the brake support so the center line of one
of the brake head mounting surfaces is above
the horizontal center line, and in line with the
vertical center line of the tapered bore on the
inboard end of the spindle. The completely
machined side of brake support plate should
face the outboard end.
3. Lubricate underside of cap screw (21) heads
and threads with multi-purpose grease Number
2 with 5% Molybdenum Disulphide. Install cap
screws and flat washers and tighten to 2007
N·m (1,480 ft lbs) torque.
NOTE: The mating surfaces between the spindle and
the brake caliper support must be clean and dry, and
with no excess cap screw lubricant on these
surfaces.
4. Install spacer (18). If necessary, tap lightly to
seat spacer against spindle. Spacer must fit
tightly against spindle shoulder.
5. Check that inner bearing cone (19) is a slip fit
on spindle (17), then remove. Install pin (26)
into slot on spindle and install inner bearing
cone (19) on spindle (17) over pin (26) and tight
against spacer (18).
NOTE: Cone is a loose fit on the spindle.
6. Install one half of seal assembly (16) on spindle
(17) using seal installation tool, TY2150 (Figure
3-7) and soft tipped mallet. For proper installa-
tion, use the following instructions:
a. Handle all parts with care to avoid damaging
critical areas. The sealing face of seal must
not be nicked or scratched.
