TRANSMISSION AND TORQUE CONVERTER 5540F/YB5515 SERVICE MANUAL

d. When the correct setting has been obtained, stake
the setting ring to the casing as shown at Y (see the
note below). Note that once staked the setting ring
can not be used again. If the ring is disturbed it must
be discarded and a new one used to re-set the end
float.
NOTE: If the slots in the setting ring fall close (within zone
Z) to the staking position Y, stake at position X
instead. In this event the ring must also be folded
on one side at position Y, fold on the side furthest
away from the slot in the ring. This is important as
the ring will otherwise restrict the flow of lubrication
oil.
35. End Float Setting - Layshaft (See Figure 7-60 and
Figure 7-61)
If the layshaft and/or its bearings have been renewed, the
shaft end float must be reset.
a. Install the torque converter housing and stand the
gearbox on the housing.
b. Tighten the setting ring A to 18.4 Ib ft (25 Nm) while
at the same time rotating the shaft via the output
yoke (a gear must be engaged). Do not over tighten
the ring. Overtightening will damage the bearings.
c. Loosen the ring a small amount to obtain a shaft end
float of 0.001 to 0.003 in (0.03 to 0.08 mm). To
measure the end float screw in a bolt at the
threaded hole in the end of the shaft. Set up a DTI
with the probe on the chamfer of the shaft. Zero the
DTI. Rotate the shaft and at the same time pull up
on the bolt, noting the reading on the DTI. Screw the
ring in or out until the end float is correct.
d. When the correct setting has been obtained, stake
the setting ring to the casing as shown at the two
positions Y (see the note below). Note that once
staked the setting ring can not be used again. If the
ring is disturbed it must be discarded and a new one
used to re-set the end float.
NOTE: If the slots in the setting ring fall close (within zone
Z) to the staking positions Y, stake at position X
instead. In this event the ring must also be folded
on one side at the two positions Y, fold on the side
furthest away from the slot in the ring. This is
important as the ring will otherwise restrict the flow
of lubrication oil.
e. Using a new gasket, refit the layshaft bearing cover.
Apply Loctite 242 to the fixing bolts and tighten to 42
Ib ft (56 Nm).
