The "C" carrier is serviced as a com-
plete assembly only. Check to see that
the "C" carrier pinions are in good con-
dition and that pinion shafts are tight
in carrier. Pinion end play in carrier
should be 0.010-0.028. Also check end
thrust surfaces and bushing in carrier;
renew carrier as an assembly if defect
is noted.
Renew Band 3 if friction material
inside band is worn, pitted or eroded or
if band has been overheated. Also in-
spect the strut sockets at band ends for
cracks or other damage.
269. To reassemble transmission,
proceed as follows: Install Band 3 and
the two struts as shown in Fig. 280,
making sure that end of flat (ac-
tuating) strut having notch is towards
the band and the end of band having an
identifying notch is towards the ad-
justing screw strut . Install thrust
washer (30-Fig. 283) on rear of dis-
tributor. Install new sealing rings (28)
on "C" sun gear, lubricate the rings
with petroleum jelly, align ring end
FORD
gaps along top side of sun gear and
carefully insert sun gear through dis-
tributor. Rotate sun gear slightly from
side to side to align splines on front end
of gear with splines in Clutch 1
housing.
Place thrust washer (1-Fig. 284)
over front end of mainshaft (13), insert
mainshaft through the "C" carrier (37
-Fig. 283), then place thrust washer
(31) over front end of mainshaft and
against "C" carrier. Carefully install
four new sealing rings (14-Fig 284) on
front end of mainshaft, lubricate rings
with petroleum jelly, align ring end
gaps along top side of mainshaft and
holding the carrier and shaft assembly
with ring end gaps up, carefully insert
shaft through "C" sun gear. Work the
shaft slowly up and down and from side
to side while pushing forward to allow
the rings to enter "C" sun gear. Rotate
mainshaft slightly from. side to side to
engage splines on front end of shaft
with splines in the "B" carrier. When
"C" carrier and mainshaft are in place
and fully forward, tighten Band 3 ad-
justing screw.
Install three new sealing rings (15)
on rear end of mainshaft, lubricate the
rings with petroleum jelly and align
ring end gaps at top side of shaft. Care-
fully install the Clutch 2 and 3 as-
sembly over mainshaft to avoid
breaking sealing rings. Partly support
clutch housing and rotate housing
slightly from side to side while lightly
pushing forward on housing to align
Clutch 2 discs with splines on "C" car-
rier. When housing is in position
against the thrust washer and "C" car-
rier, pull mainshaft rearward while
lifting up on clutch housing so that
snap ring (16) can be installed in
groove on rear end of mainshaft.
270. OVERHAUL CLUTCH AS-
SEMBLIES ( Except Direct Drive
Clutch). The following service proce-
dure will apply to all transmission
clutch assemblies except the Direct
Drive Clutch. The illustrations (Figs.
285 through 289) are of the 2-speed
PTO clutch; however, the other clutch
assemblies are of similar construction.
Refer to Fig. 284 for exploded view of
the Clutch 2 and 3 assembly; to Fig.
250 for Clutch 1 assembly and to Fig.
305 or 306 for PTO clutch assemblies.
To disassemble clutch, proceed as fol-
lows:
Remove the pressure plate retaining
snap ring as shown in Fig. 285. NOTE:
Ends of snap ring in the Clutch 1 and
Clutch 2 and 3 assemblies are welded
together; break weld with sharp chisel,
then remove and discard snap ring. On
Clutch 1 assembly, the "B" ring gear
also functions as the clutch pressure
