This operation consists in obtaining an end play J1 of
0.60 to 0.80 mm between the pump cover (2) and the
spacer (4) (Fig. 11).
Remove the PTO shaft to perform this operation.
60. Install the clutch on the cover (38) of the reverse
clutch, using the tool used in Fig. 5, § B.
61. Fit a 2 mm shim (3) on cover the (2) (Fig. 11).
62. Lubricate the lip of seal (10). Protect the lip of the
seal by fitting a protector (see section 3) on the
splines of the shaft (19). Fit two guide screws on
opposite sides of the gearbox housing and tempo-
rarily fit the spacer (4) without Loctite. Gradually
tighten several screws.
63. Place a dial gauge at the end of shaft (19) and
check the clearance by moving the shaft sideways
(Fig. 11).
I
MPORTANT: Check that the snap ring (65) of the
bearing (32) is correctly in contact with the cover
(38) (Fig. 11).
64. Remove spacer (4).
Depending on the reading previously obtained with
the dial gauge, define a new thickness for shim(s)
(3) in order to obtain a J1 clearance of between
0.60 and 0.80 mm (Fig. 11).
