buffer is taken off (right);
The Motor-Propelling set is taken out and
then placed on a stand.
Re- Mounting
The steps are taken in the re verse order (see dismantling / taking apart).
To do:
-the filling-up a nd the drainage of the cooling circuit (see Chapter “ Filling-up and
Dr aining”).
CAUTION! USE ONLY TYPE D A NTIFREEZE.
- filling-up the engine and the gearbox with oil;
- filling-up and draining the clutch hydraulic command circuit (see Chapter “Draining
of the clutch hydraulic command circuit”); The liquid to use is brake fluid type SAE J 1703, DOT 3, DOT 4.
The screws and the screw-nuts of the couple are fastened back.
When mounting, line up markings from hoses and related parts.
The Motor-Propelling set is upheld by
the two handles, by means of a m oving
lifting device (a mobile crane);
The four screws fixing the Motor-Propel-
ling set ba ttery stand are taken off, as well
as the screw-nut of t he elastic buffer;

E-MOUNT ING
The lower c rankcase is cleaned.
A ca. 3 mm-thick girdl e of RHODERSEAL
5661 is applied, as in the adjoining drawing. Do not forget to replace the two cres-
cent-sha ped fitti ngs at the e nds of the
crankcase.
Mind that the relative displacement be-
tween the lower crankcase and the cylin-
d er crankcase, along the gearbox-assem-
b ly surface, should not exceed 0.3 mm.
