Notes On Renewing The Alternator - Hatz 2-4L30 Workshop Manual

Notes on renewing the alternator:

When series production of Series L / M
engines began, alternators made by SEV-
MARCHAL were used.
These alternators are no longer available
as spare parts, but can be replaced
without difficulty by the current VALEO
alternator.
The MARCHAL voltage regulator is still
available.
In view of the modified installed position
of the voltage regulator on PARIS-
RHONE or VALEO alternators (removal
and installation in a radial direction to
reduce the risk of breaking off the carbon
brushes), the fan housing was also 195
modified in the regulator area when the
PARIS-RHONE generator was introduced.
A cutout in the housing and deletion of
the retaining screw which previously
passed through at this point ensure that
the regulator switch can be renewed with-
out having to remove the alternator.
When replacing a MARCHAL alternator
by a VALEO type, you are recommended
to perform the above modification; refer to
Fig. 195. The time invested in this will
easily be made good by the time saved if
the regulator has to be replaced later.
When installing a VALEO voltage
regulator, make sure that the condenser
supplied with it is also installed (connec-
tion diagram is enclosed).
