INSTALLING FOURTH, THIRD, FORWARD
CLUTCHES
a. Fourth Clutch, Third Clutch
(1)
Prior to the installation of the fourth-clutch
assembly, be sure the bearing races at both the front
and back are in place.
If not, refer to figures 6-25 and 6-
26.
Check also that the step-joint sealrings, bearing and
race are in place on the center support (fig.
5-21).
(2)
Place lifting bracket 18 (fig.
4-2) under the
spring retainer of the fourth-clutch assembly (refer to fig.
5-32).
Carefully lower the fourth clutch into the
transmission.
Engage the internal splines with splines on
the center sun gear shaft.
(3)
Be sure the bearing race at the top (front)
of the clutch is in place.
If not, lubricate it with oil-soluble
grease and install.
(4)
Install 8 third-clutch plates (fig. 7-32),
beginning with a thick external-tanged plate and
alternately installing 4 external tanged plates and 4
internal-splined plates.
(Refer to para 7-2b(l), above.).
CAUTION
Be sure the clutch plate next to the
piston is a thick plate.
(5)
Install the back plate.
To insure proper
tang to housing slot alignment, use figure 7-32 as a
guide.
(6)
Install the third-clutch snapring (fig.
7-33).
Be sure the gap of the snapring is at the top of the
transmission housing.
(7)
Check the third clutch running clearance
by inserting gage 43 (fig.
4-3) between the snapring and
the back plate of the third clutch (fig.
7-33).
The
clearance should be 0.
060to 0.
120-inch (1.
52 to 3.05
mm). Any dimension between 0.060 to 0.120 inch is
satisfactory.
However, the closer the clearance is to 0.
060 inch, the longer the interval between clutch plate
replacements will be.
Replace worn plates with new
plates to establish the desired clearance.
If the
assembly is satisfactory, continue assembly with b,
below.
Clearance must not be less than 0.
060 inch.
(8)
If the clearance is not satisfactory, remove
the fourth clutch assembly and replace plates in the third
clutch as required to obtain a satisfactory clearance.
Refer to paragraph 7-2.
Reinstall the fourth clutch
assembly and reassemble the third clutch when the
clearance is satisfactory.
