side and all bolts heads located in the adapter.
. Tightening of all drive bolts
should be done with the center component
assembly in a horizontal position. The most reli-
able method of tightening drive bolts is achieved
using Drive Bolt Elongation. Measure the length
of the #1 drive bolt with an outside micrometer
and record. Hold the drive bolt head and tighten
the nut to the tightening torque listed in
Subtract the first reading from the second read-
ing. Compare the difference to the elongation
listed in
increase or decrease tightening to achieve prop-
er elongation. Repeat this procedure for each
drive bolt in cylinder head fashion illustrated in

SHRINK DISC INSTALLATION
supplied ready for installation. Therefore, they
should not be disassembled prior to initial installa-
tion.
INSTALLATION SEQUENCE
1. Remove spacers placed between collars for pro-
tection during transportation.
2. Take any three locking screws forming the points
of an equilateral triangle (e.g. screw 1, 5 and 9
in Figure
) and tighten them slightly until the
inner ring can still just be turned.
3. Slide shrink disc over the hub. The hub outside
surface can be greased.
Never tighten locking screws before shaft is inside
the hub.
4. Degrease the hub bore and shaft seat.
5. Insert shaft or slide hub over the shaft.
6. Refer to Figure
. Tighten all locking screws
gradually and all the way around (not in diamet-
rically opposite sequence).
Several passes are required until all screws are
torqued to specified tightening torque of 42 ft.-lbs.
(57 Nm). Check tightening torque (42 ft.-lbs. [57
Nm]) with a torque wrench. Both collars must
remain an equal distance apart.
REMOVAL
Shrink disc removal procedure is similar to installa-
tion.
1. Gradual release of locking screws all the way
around. Initially each screw should be released
about a quarter of a turn only. Thus tilting and
jamming of collars will be avoided.
DO NOT
remove locking screws.
2. Remove shaft or pull hub from the shaft. Any rust
formed on shaft in front of hub must first be
removed.
3. Pull shrink disc from hub.
CLEANING AND LUBRICATION
Removed shrink discs need not to be taken apart or
lubricated prior to reinstallation. Only a dirty shrink
disc should be cleaned and lubricated.
For the tapered surfaces, use one of the lubricant
recommendations shown in
