28. Install the B1 clutch "stepped" pressure plate, as
shown in Figure 178, with "step" facing down.
29. Install B1 clutch pack beginning with a friction
plate onto the pressure plate and alternating with
a steel plate, as shown in Figure 178, until you
have installed the proper quantity, as the quantity
may vary.
Note: All friction plates should be soaked in
proper fluid for 30 minutes before installing.
30. Install the B1 clutch backing plate on top of the
last friction, as shown in Figure 178, with the
rounded edge facing the friction.
Note: Notice the number stamped on top side
of backing plate, which is an indicator that it
is selective, but no selectives available as yet.
31. Install the B1 clutch "bellville" cushion plate in
the direction shown in Figure 178.
Note: There is no backing plate snap ring for
the B1 clutch pack. We will check B1 clutch
clearance before installing oil pump, as the
apply piston is in the oil pump assembly. The
apply piston caged return spring assembly sits
between the piston and cushion plate, retaining
the B1 clutch pack.
32. Install K3 clutch housing drive hub, as shown in
Figure 179, and engage on splines of sun gear.
33. Install the number 6 thrust bearing race into the
drive hub, as shown in Figure 179.
34. Install the number 6 thrust bearing with needles
facing down, as shown in Figure 179.
35. Install completed K1 clutch housing, as shown
in Figure 179.
36. Ensure that number 5 thrust bearing race is still
in place on K1 clutch housing, as shown in
Figure 179.

and forth to engage K1 clutch frictions into the
planetary hub until fully seated.
39. Install K3 clutch housing assembly, as shown in
Figure 181, by rotating back and forth until it is
fully seated.

TRANSAXLE FINAL ASSEMBLY (CONT'D)

41. Measure the distance from case pump surface to
the washer surface on the K3 clutch housing, as
shown in Figure 182, using a straight edge and
ruler, or a depth micrometer.
Note: This measurement should match the
measurement taken on disassembly to ensure
that K3 clutch housing is fully seated.
42. Install "H" gage on transaxle pump surface, as
shown in Figure 183, lower the adjustment rod
to the piston surface (See Inset in Figure 183)
of the B1 apply ring/return spring assembly and
tighten the adjustment rod locking knob.
43. Now turn the "H" gage over and set it on the
completed oil pump assembly, "with" the new
design gasket, as shown in Figure 184.
44. Measure with feeler gauge between adjustment
rod and B1 clutch piston to determine the B1
clutch clearance.
45. B1 clutch clearance should be approximately
0.26 mm (.010") per friction plate installed.
