NOTE:
“F” is the deviation of the lower case dimen-
sion from standard. The “F” mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “F”
mark unreadable, assume that “F” is zero
and check the backlash when the unit is
assembled.
Example:
If “M” is “24.00 mm” and “F” is “+5”, then
T1 = 24.42 + (+5)/100 – 24.00 mm
= 0.42 + 0.05 mm = 0.47 mm
If “M” is “24.00 mm” and “F” is “–5”, then
T1 = 24.42 + (–5)/100 – 24.00 mm
= 0.42 – 0.05 mm = 0.37 mm
3. Select the forward gear shim(s) (T1) as
follows.
Example:
If “T1” is “0.47 mm”, then the forward gear
shim is 0.45 mm.
If “T1” is “0.50 mm”, then the forward gear
shim is 0.48 mm.

Measuring the forward gear backlash
1. Remove the water pump assembly.
NOTE:
Do not remove the oil seal housing in this
procedure.
2. Set the gear shift to the neutral position
at the lower unit.
Forward gear shim thickness (T1) =
