adjustments for the Series 10 and 20 cars being
illustrated in Fig. 17. Service operations on the
rear brake controls are similar to those on the front
control common to the "C" series cars.
Improved Alemite fittings are provided for
lubrication of the front and rear brake cables.
Lubrication of the cam bearings is done in the same
manner as on the "C" series by removing the cams
and packing the bearings with chassis grease-
The brake and clutch pedal assembly is new. It
is no longer mounted on the transmission but on
the side member of the frame. On the Series 10
and 20 cars, the pedal assembly is carried in a
bracket attached to the inside of the frame side
member while on the longer wheelbase models it
straddles the side member with the brake pedal on
the inside and the clutch pedal outside. See Figs.
20 and 21.
Clutch
The new clutch used on the 355-D and 370-D
cars is shown in Fig. 19 and is essentially the same
as the two plate clutch formerly used, but it has
been refined to give smoother operation and.longer
life. The design of the 452-D clutch, however, is
the same as used on the "C" series except the spring
mounting.
The spring mounting on all clutches is new. The
rear driving piate is no longer drilled to receive the
individual spring supports. Instead, four new type
supports, each carrying three springs, are used.
Each of these new supports is riveted to the rear
driving plate at two points and in addition is
provided with two extensions or legs to provide a
four point contact with the driving plate. This
construction gives a better distribution of pressure
over the driving plate resulting in a more nearly
uniform engagement of the clutch over the entire
surface of the facings and a better retainment of the
springs at high engine speeds.
Due to these new spring supports, together with
improvement in the clutch metal, the double lever
release mechanism is no longer used in the clutches
for the 8 and 12-cylindcr engines. Consequently,
the clutches arc provided with single type release
levers. See Fig. 19. The double lever release
mechanism, however, is retained in the 452-D
clutch due to the necessity of some means of compensation
for springiness in the levers and pressure
plates in the larger size clutch.
The driven discs for the 370-D clutch have curved
spokes the same as in the "C" series and the same
precautions should be taken to install the discs
with the spokes leading out from the hub in a
clockwise direction when viewed from the flywheel
side of the clutch. All other clutches use discs
with straight spokes.
These improvements in design and metal have
also resulted in a better heat balance between the
center and outside driving plates, in all clutches.
As a result, there is less change in operation between
a hot clutch and a cold one. Chattering is
also greatly reduced when the clutch is hot.
When servicing the new clutches, it is important
that the driven discs be matched. This is necessary
to give even contact of both discs for smooth engagement
during the initial wear on the facings or
the break-in period. The two discs and facing
assemblies should be matched so that there is not
