Cadillac 355-D, 370-D and 452-D
A new harmonic balancer is used in the 12 and
16 cylinder engines. This balancer employs rubber
as the dampening medium.
The oil filter has been discontinued on the 8
cylinder engines.
The vacuum pump has been redesigned for greater
efficiency and longer life.
No major change has been made on many of the
parts, such as the camshaft, the front end drive,
and the connecting rods on the 355-D, which are of
the same design and fully interchangeable with the
* corresponding "C" series parts. The 355-D
cylinder blocks with the double valve springs may
be used on "C" series engines eithe: in pairs or
individually.

slot is to compensate for expansion of the piston.
Four rings, one plain and two notched compression
rings and one oil ring are used on each piston as
shown in Fig. 35-
Several other changes have been made internally
in the engines to give them better performance and
longer life; dual valve springs are used on the 355-P;
oil bleed holes are,provided on the 370-D and 452-D
connecting rods; bronze bushings have been added
to the valve lifter rollers on all models; two springs
are now employed on the 370-D and 452-D dashpots.
The cylinder bores in all engines are also
honed to a smoother finish for the use of the Lynite
pistons.
A slight change has been made in the engine
supports on all models to provide a softer mounting.
The front and intermediate supports are adjusted in
practically the same manner as in the "C" cars.
Adjustment of the support at the rear end of the
transmission is made by using shims between the
upper and lower halves of the rubber retainer.
Care must be exercised in adjusting the transmission
support not to get it too tight.
