WARNING! Check the vehicle’s Manual for the
transmission specications to make sure the 1st
speed gear ratio matches to the gear ratio shown in
the table above. If not, calculate the torque amount
as follows.
• Specied torque for the nut: 217 to 270 N.m
Example:
Transmission 1st gear ratio: 4.473
• Divide 217 by 4.473 and round off to the higher
nearest integer:
217 ÷ 4.473 = 48.51 use 49
• Divide 270 by 4,079 and round off to the lower
nearest integer:
270 ÷ 4.473 = 60.36 use 60
Torque to be applied on the tool: 49 to 60 N.m
EA100
To tighten the nut, check the table below for the
torque to be applied on the tool using the 1st speed
reduction ratio.
Transmission Gear ratio at 1st speed
Torque to be applied
FSO 2105A 4.473 49 to 60 N.m
FSO 2505A/B 4.079 54 to 66 N.m
29. Remove the tools.
Note:
As an option for the above procedure,
the special tool E014010 may be used
for locking the mainshaft and the tool
E006006 to tighten the nut. In this case,
the torque is applied directly to the nut and
the specied amount is 217 to 270 N.m.
30. Lock the mainshaft nut using a center punch.
33. Install the rear cover.

32.
Apply Eaton 680 gasket compound to the rear
cover mounting surface with the intermediate
housing.

31. Install the retaining ball that locks the
speedometer rotor on the mainshaft and then
install the rotor. Install the rotor snap ring.
Note:
Use grease to hold the ball in place.
