Assembling of governor:
– Assemble the governor by working the
reverse order of dismantling; refer to
Figs. 48 and 48a.
Note:
When assembling the governor make
quite sure that all moving parts are able
to move freely.
On L/M 31/40 engines there must be a
clearance of 0.5 mm between spring plate
(48a/43) and nut (48a/44).
On L/M 41 engines the spring plate
(48a/43) must be held firmly when nut
(48a/44) is tightened.
– Install the spring for the governor (55/1)
so that the endface of the tapered sec-
tion points in the direction of rotation.
Renewing governor spring:
(without detaching the timing case cover)

see M 20.00.
– On the H.L30 take off the cover;
