fuel shut-off cable, engine oil pressure
gage line, tachometer cable, air cleaner
hose and ground strap. On models so
equipped, disconnect hydraulic oil lines,
power steering lines, drag links, radius
rods
and/or horizontal mufller. On all
models, remove screws attaching the
rear
fuel tank mounting bracket and
block tank up as shown in Fig. 115 us·

a guide stud in each side of transmission
housing to assist in alignment. Turn
flywheel to align clutch plate splines
with transmission and pto input shaft
splines. When engine and transmission
flanges meet, install retaining cap
sc
r
ews and remove guide studs. Do not
use
cap screws to force units together as
damage to clutch and transmission may
result. Complete installation by revers

cover, pto pressure plate, drive plate and
transmission pressure plate
so
parts can
be
reasse
mbled in the same relative posi·
tions.
Unhook
release lever torsion
springs (22-Fig. 118). Back off"T" bolt
nuts until pivot pin retainer pins (21),
early style clutch, can
be
driven free of
pivot pins (20). Do not attempt to drive
retaining pins completely out of cover.
On late style clutches, remove retaining
clips from release lever pivot pins. On all
models, remove p1vot pins and lever
springs. Disconnect release levers (17)
from links (4 ). Loosen
"T"
bolt nuts even
ly to release spring pressure, then
remove
"T"
bolts and separate clutch
components.
Thoroughly clean and examine all
parts for wea1· or damage. Renew any
parts which are questionable. Flywheel
friction surface may be resurfaced up to
a maximum depth of 1.0 mm (0.040
inch). An equal amount of material must
also be removed from clutch mounting
surface of flywheel to maintain correct
clutch spring tension. It is not permissi
ble to resurface pressure plates (7 and
14) or dnve plate !12). Insulating
washen;

should
be
renewed when new
