torque.
• If the specified starting torque is exceeded, re-
place the expander with a new one and reas-
semble the final drive pinion gear assembly.
• Make sure that the distance "a" is 67.5–68.1
mm (2.66–2.68 in) as shown.

a. To find the final drive pinion gear shim thick-
ness "A", use the following formula.
Final drive pinion gear shim thickness
"A" = "a" + ("c" - "b") - "d"
"a" = 55 mm
"b" = a numeral (usually a decimal number)
on the final drive pinion gear either added to
or subtracted from "22.2"
"c" = a numeral (usually a decimal number)
on the final drive pinion gear bearing housing
either added to or subtracted from "67.8"
"d" = a numeral (usually a decimal number)
on the final drive case either added to or sub-
tracted from "100"
