(45) Orient 2/4 clutch return spring to retainer as
shown in (Fig. 134), and install to transaxle (Fig.
135).(46) Using tool 5058, compress 2/4 clutch return

(47) Install snap ring.
(48) Set up dial indicator as shown in (Fig. 137)
and measure 2/4 clutch clearance. Press down on
clutch pack with finger and zero dial indicator.2/4
clutch pack clearance is 0.76-2.64 mm
(0.030-0.104 in.).Set up indicator and record mea-
surement in four (4) places. Take average of read-
ings. If clearance is outside this range, the clutch is
assembled improperly.There is no adjustment for
2/4 clutch clearance.
(49) Install rear sun gear and #7 needle bearing
(Fig. 139).
NOTE: The number seven needle bearing has three
anti-reversal tabs and is common with the number
five and number two position. The orientation
should allow the bearing to seat flat against the
rear sun gear (Fig. 138). A small amount of petrola-
tum can be used to hold the bearing to the rear sun
gear.

(c) Remove oil pump o-ring (Fig. 144).Be sure
to reinstall oil pump o-ring after selecting the
proper #4 thrust plate.

shown in (Fig. 145).
(e) Measure the input shaft end play with the
transaxle in the vertical position.Input shaft end
play must be within 0.005 to 0.025 inch.For
example, if end play reading is 0.055 inch, select
No. 4 Thrust Plate which is 0.071 to 0.074 thick.
This should provide an input shaft end play read-
ing of 0.020 inch which is within specifications.
(f) Refer to the No. 4 thrust plate chart to select
the proper No. 4 thrust plate:

ACCUMULATOR
DESCRIPTION
The 41te underdrive, overdrive, low/reverse, and
2/4 clutch hydraulic circuits each contain an accumu-
lator. An accumulator typically consists of a piston,
seals, return spring(s), and a cover or plug. The over-
drive and underdrive accumulators are located
within the transaxle case, and are retained by the
valve body (Fig. 169) .
The low reverse accumulator (Fig. 170) is also
located within the transaxle case, but the assembly is
retained by a cover and a snap-ring.
The 2/4 accumulator is located in the valve body. It
is retained by a cover and retaining screws (Fig. 171)
.
OPERATION
The function of an accumulator is to cushion the
application of a frictional clutch element. When pres-
surized fluid is applied to a clutch circuit, the appli-
cation force is dampened by fluid collecting in the
respective accumulator chamber against the piston
and spring(s). The intended result is a smooth, firm
clutch application.
