ADJUSTING SECONDARY SHAFT END FLOAT FOR THE
5-SPEED GEARBOX
1 - (For all models) - Interpose a calibrated shim A selected from
the following four thickness:
- A code 2.1559.737.0 thickness 2.15 mm;
- A code 2.1559.738.0 thickness 2.30 mm;
- A code 2.1559.739.0 thickness 2.45 mm;
- A code 2.1559.740.0 thickness 2.60 mm;
in order to completely eliminate all end float of the secondary shaft.
2 - (For Agroshift models only) - Proceed as follows:
after having installed bearing F and shaft B, measure the stand-in
C of the face of the bearing relative to the wall of the gearbox
casing whilst pushing the bearing towards the rear of the gearbox
casing. Install shims D to the same thickness as the value mea-
sured, and check, after installation of flange E, that there is no play
or preload on the bearing.
- D code 2.1580.304.0 thickness 0.5 mm;
- D code 2.1580.303.0 thickness 0.2 mm
- D code 2.1580.310.0 thickness 0.05 mm

home into the transmission housing C.
The two bushes must be positioned with the threaded
