General:
Speed control systems are different in
construction as far as their use in connec-
tion with bowden or solenoid control is
concerned.
Preparations:
Ref.: M-Disassembly cross reference
scheme.
Version I
Early serial production.
Unsuitable in connection with bowden or
solenoid control due to no frictionless
movement of the speed control.
Version II
Early serial production.
Suitable in connection with bowden or so-
lenoid control.
A conversion from Version I to Version II is
possible by fitting the shaft assembly ac-
cording to Version II.
Dismantling:
– Remove in numerical sequence 1...13.
Governor lever 12 may remain as a unit,
except for repair purposes.
Inspection / repair:
– Check all parts for wear or any other
damage.
Assembly:
– Assemble in reverse sequence 13...1.
Apply locking agent as specified !

Conversion:
Version I / II
Replaceable by Version III in case all parts
in question become replaced.
Version III / IV
Identical in construction but different in the
dimensions of the speed control stop 25
and fitted as follows:
Version III = crankcase in sand casting
Version IV = crankcase in diecasting
Version IV
Not interchangeable by Version III.
The possibility of the injection pump con-
trol sleeve sliding out of the governor lever
guidance slot could occur i.e. the engine
would not start.
The speed control stop 25 can be different
too (with or without pin) but remains inter-
changeable within Version IV.
