TRANSMISSION REPAIR (Continued).
(d) Remove the snapring (199) that retains the
fourth clutch hub (200) in the forward
clutch housing (201). Remove the fourth
clutch hub (200) and the forward clutch
hub (202) from the housing.
(e) Remove thrust bearing race assembly
(203), the bearing assembly may adhere to
either forward clutch hub (202) or the hub
of forward clutch housing (201). Remove
five internal-splined plates (204) and five
external tanged plates (205) from the
forward clutch housing (201).
(f) Place the housing and shaft assembly in a
press. Using compressor tool, depress the
spring retainer (206) and remove the
retainer (206) piston return spring (208)
and piston (209). Remove sealring (210)
from the piston (209) and sealring (211)
from the housing (201).
(g) Remove balls (212) from housing and
shaft assembly (213) only if replacement is
necessary. If necessary, clear the bores of
staked metal and remove the balls.
(h) Remove pin (214), plug (215), valve spring
(216) and valve (217) from the outer
circumference of forward clutch housing
(i) Press turbine shaft (218) from housing
(201) only if replacement is necessary. To
press the shaft from the housing, place the
assembly, shaft downward, in a press.
Support the assembly at the front hub of
(a) If turbine shaft (218) was removed, press
the new one to a firm seat against housing
(201). To ensure a satisfactory fit, a
minimum of 250 lb (1112 N) press out
force is required. The total runout must be
within 0.005 inch (0.127 mm).
(b) Inspect centrifugal valve parts (214, 215,
216 and 217) for damage. If damaged,
replace with new parts. Be sure the color
code of any new part is the same as the
part replaced. All three parts (214,215, and
216) must be identically coded.
(c) Install centrifugal valve (217), conical end
first, into its bore in forward clutch housing
(201). Place spring (216) inside the valve.
Compress the spring with plug (215) and
retain the spring and plug with pin (214).
(d) If balls (212) were removed, replace them.
Place each ball in its bore. Stake each
bore at three equally spaced places. Each
bore is properly staked when the ball has
at least 0.040 inch (1.02 mm) axial
movement and when the ball is retained by
the stakes when a 30 lb (133 N) load is
applied against the ball.
(e) Before completing the assembly, the clutch
method is by direct measurement and is
outlined in steps (f) through (k).
If either piston sealring (210 or 211) is
installed incorrectly, the forward clutch
will not operate properly.
(f) Position the clutch housing and shaft
assembly (213) shaft downward, on a work
table. Lubricate and install the piston
sealrings (210 and 211) into their grooves
in the housing hub and piston. Make sure
the sealring lips face toward the oil
pressure side of the piston. Install the
piston (209) into the housing.
(g) Alternately install the five external-tanged
plates (205) and five internal-splined plates
(204). Install the fourth clutch driving hub
(200) and retain it with the snapring (199).
