Gradall 534B (9103-1390) Service Manual - Manual (Page 169)

Remove all burrs from flywheel mounting face and
nose pilot bore. Clean drive plate surface with
solvent.
Check engine flywheel and housing for conform-
ance to standard S.A.E. #3 - S.A.E. J-927 tolerance
specifications for pilot bore size, pilot bore runout
and mounting face flatness. Measure and record
engine crankshaft end play.
Install two 2.50 [63, 50 mm] long transmission to
flywheel housing guide studs in the engine fly-
wheel housing as shown. Rotate the engine
flywheel to align a drive plate mounting screw
hole with the flywheel housing access hole.
Install a 4.00 [101,60 mm] long drive plate locat-
ing stud .3750-24 fine thread in a drive plate nut.
Align the locating stud in the drive plate with the
flywheel drive plate mounting screw hole posi-
tioned in step No. 3.
Locate transmission on flywheel housing aligning
drive plate to flywheel and transmission to fly-
wheel housing. NOTE: Fig. 4 installation, align
drive plate holes with flywheel studs.
Install transmission to flywheel housing screws.
Tighten screws to specified torque. Remove trans-
mission to engine guide studs. Install remaining
screws and tighten to specified torque.
Remove drive plate locating stud.
Install drive plate attaching screw and washer.
Snug screw but do not tighten. NOTE: Fig. 4 in-
stallation, install drive plate attaching washers and
nuts. Tighten each nut 28 to 30 ft. lbs. torque
[38,0- 40,6 N.m]. Some engine flywheel housings
have a hole located on the flywheel housing cir-
cumference in fine with the drive plate screw access
hole. A screwdriver or pry bar used to hold the
drive plate against the flywheel will facilitate in-
stallation of the drive plate screws. Rotate the en-
gine flywheel and install the remaining seven (7)
flywheel to drive plate attaching screws. Snug
screws but do not tighten. After all eight (8) screws
are installed torque each one 25 to 30 ft. lbs. torque
[33,9 -40,6 N.m]. This will require torquing each
screw and rotating the engine flywheel until the full
amount of eight (8) screws have been tightened.
Measure engine crankshaft end play after transmis-
sion has been completely installed on engine fly-
wheel. This value must be within .001 [0,025mm]
of the end play recorded in step No. 2.
Does not apply to units having 3 intermediate
drive plates. See Fig. 4.
