Transmission

8. Begin securing the transmission to the flywheel
housing with M10 lock washers and M10 x 1,5 x 30 mm
PC8.8 hex-head capscrews. Remove the two M10 x
1,5 x 63,5 mm guide studs (dowels) after several
capscrews and washers are installed. When
installing the washers and capscrews, tighten bolts
evenly in stages and assure that the transmission
converter housing installs evenly against the engine
flywheel housing.
Note: If the transmission is not aligned properly with the
engine, the torque converter will angle against the drive
plate and damage will occur when the engine is started.
9. When all twelve capscrews and washers are
installed, torque each capscrew to 37 lb/ft (50 Nm).
10. Remove the 3/8-24 NF x 4" threaded stud, serving as
a drive plate locating stud (Fig. 7–9), and install a
3/8-24 NF flywheel-to-drive plate capscrew with a
3/8" lock washer in place of the stud. Partially, but not
completely, tighten the capscrew.
Note: Due to different flywheel thicknesses, different fly-
wheel-to-drive plate capscrews are used. For the Cummins
engine, 3/8-24 NF x 1-3/4" Grade 8 hex-head capscrews
are used. For the Perkins engine, 3/8-24 NF x 2" Grade 8
hex-head capscrews are used. Use Loctite
® #242 (blue)
on all flywheel bolts.
Figure 7–10. Transmission to engine fasteners.
11. Insert an engine barring tool into the sight plug hole
(Fig. 7–6, Cummins engine shown) and advance the
flywheel to the next screw hole and drive plate weld
nut. Continue installing and partially tightening the
remaining capscrews and washers and rotating the
flywheel and drive plate.
12. When all eight capscrews and washers are installed,
torque the capscrews to 26-29 lb/ft (35-39 Nm). This
will require torquing each screw and rotating the
engine flywheel until all eight of the capscrews are
tightened.
13. Remove the hoist or overhead crane and sling.
14. Continue making hook-ups of previously
disconnected items, hoses, etc. Before attaching the
main pump hose, fill the pump with hydraulic fluid by
hand to prime it.
15. Clean the transmission oil filter mounting surface.
16. Apply a clean film of clean 10W motor oil to the new
filter gasket. Install the new filter and torque 20-25 lb/ft
(27-34 Nm).
Note: 10W motor oil is recommended in most climates;
however, 5W20 motor oil may be substituted for use in
conditions -30°F to 70°F (-34°C to 21°C) only.
17. Transmission oil may be added through either the fill
plug or dipstick holes. Remove the fill plug or dipstick
and add approximately 3.4 gallons (12,9 liters) of
10W motor oil. Check the oil level by taking
intermittent dipstick readings as outlined in Checking
the Transmission Oil Level. DO NOT overfill.
Reinstall the fill plug or dipstick when finished.
18. Coat the drive shaft yoke-to-transmission M12-1,75 x
35 mm hex-head capscrews with Loctite ® #242
(blue). Install the yoke with the capscrews and
hardened M12 flat washers. Torque the capscrews to
83 lb/ft (112,5 Nm).
19. Connect the wiring harness terminals to the
transmission solenoids.
20. Remove the caps and install the transmission oil
cooler inlet and outlet lines at the transmission (Fig.
7–3). The transmission oil cooler outlet hose, routed
to the lower radiator fitting, is located on the right or
hydraulic reservoir side of the transmission. The
transmission oil cooler inlet hose, routed to the upper
radiator fitting, is located on the left or boom side of
the transmission, just below the position occupied by
the main hydraulic pump.
21. Attach the main hydraulic pump to the transmission.
Align the splined pump drive shaft with the
transmission drive and secure the pump to the
transmission with 1/2-13 x 1-1/2" hex-head
capscrews, 1/2" lock washers and 1/2" plain washers.
Torque capscrews to 75 lb/ft (102 Nm).
22. Uncap and install the hydraulic inlet and outlet hoses
on the main hydraulic pump.
23. Install the engine air cleaner assembly and the
bracket supporting the air cleaner inlet hose at the
turbocharger assembly on turbocharged engines.
