5 GEARBOX UNIT REASSEMBLY ON THE
BENCH
After all the checks, tests and replacements reassemble
the gearbox as follows:
Bearing assembly on the gearbox housing and on
the cover
N.B. Warm up the gearbox housing and cover at
a temperature of roughly 150° ÷ 160°C before
assembly
Firstly, carefully clean the bearing seats and rings with
solvent (trichloroethylene). Then use a brush to spread a
slight layer of "Loctite" on the outside of the bearing
external ring, within the gearbox housing and cover, where
the bearings should be placed.
Make sure that there is no "Loctite" among the bearing
balls or rollers.
The bearings to be assembled with "Loctite" are the
following:
• Clutch shaft bearing on the housing.
• Secondary shaft bearing on the housing.
• Secondary shaft bearing on the cover.
Bearing pressing within their seats on the gearbox
housing
To press the bearings on the gearbox housing proceed
as follows:
• After being covered with "Loctite", the clutch shaft
bearing shall be pressed with the relevant punch code
14928900 see chapter 5, section B.
• After being covered with "Loctite", the secondary shaft
bearing external ring shall be pressed with the relevant
punch code 14929100, see chapter 5 section B.
• The primary shaft bearing shall be pressed with the
relevant punch code 14928800, see chapter 5 section B.
Bearing pressing within their seats on the gearbox
housing cover
To press the bearings on the gearbox housing proceed
as follows:
• After being covered with "Loctite", the secondary shaft
bearing shall be pressed with the relevant punch code
14928900, see chapter 5 section B.
• The primary shaft bearing shall be pressed with the
relevant punch code 14929000, see chapter 5 section B.
• The clutch shaft bearing shall be pressed with the relevant
punch code 14928800, see chapter 5 section B.
N.B. Once the bearings have been pressed in
their seats, on the gearbox housing and on its
cover, it is necessary to leave them settle for 12
hours. This allows the "Loctite" to dry before
starting the gearbox assembly.
