Fault Code Guide

15.1 Pull the transmission and jack straight
back until the transmission input shaft is
clear of the clutch.
15.2 Turn the left-hand front wheel to allow
room for the transmission to pass. If nec-
essary, lower the jack supporting the
transmission. It might also be necessary
to jack up the truck to get enough clear-
ance to allow the transmission to pass.
IMPORTANT: Watch closely the clearance
between the bell housing and the leaf
spring.
15.3 Pull the transmission out through the
space behind the front wheel.
Installation
IMPORTANT: Before installing the transmission,
make sure that the rear tires are chocked and
that the transmission is securely chained to the
support plates on the transmission jack.
1. Install the transmission. See Fig. 14.
1.1 Align the jack and the transmission behind
the engine.
1.2 Raise the transmission and adjust the
angle of the jack until the bell housing and
the timing case flange are parallel.
1.3 Push the transmission and jack straight
forward.
NOTE: While installing the transmission
mounting capscrews, also install the battery
cable bracket(s), as removed.
1.4 Install the eleven M10 transmission
mounting capscrews. Use a crossover pat-
tern. Do a final tightening of the cap-
screws to 33 lbf·ft (45 N·m).
1.5 Remove the chain around the transmis-
sion and the jack; then remove the jack.
2. Install the exhaust clamp at the exhaust elbow,
as removed.
3. If the vehicle is equipped with the optional dual
fuel tanks, install the fuel cross-over line and its
support between the tanks. Tighten the clamps
40 lbf·ft (54 N·m) and the mounting bolts 95 lbf·ft
(129 N·m).
4. If removed, coat the mating surface of the PTO
cover with Loctite
®
509 or equivalent sealing
compound. Install the PTO cover on the trans-
mission. Tighten the M10 hardened mounting
capscrews 43 lbf·ft (58 N·m). Lock the nut retain-
ers in place.
5. Connect the driveshaft.
5.1 Slide the front of the driveshaft into the
transmission output yoke.
5.2 Install the U-joint end caps on the output
yoke. Tighten the bolt heads 50 lbf·ft (68
N·m) for 3/8-inch end cap bolts and 110
lbf·ft (149 N·m) for 1/2-inch end cap bolts.
5.3 Install the midship bearing bracket, as re-
moved. Tighten the nuts 95 lbf·ft (129
N·m).
