l 9i9 Service Information 3 Body Striking appearance changes characterize the new 39-series Cadillac and LaSalle cars, but the bodies of these cars are very familiar in design and construction to the corresponding 3 8-series bodies. Both the Fisher and the Fleetwood bodies are of familiar steel, turrettop construction. Five different chassis models with 36 body styles as listed below comprise the 1939 line. This listing gives in detail the arrangement of seats and windows, and locations of spare tires and luggage space. Door and window arrangements are the same as for the corresponding previous series. Individually-controlled ventilation is continued in all body styles, with sliding panes of new design in the rear quarter windows of coupe and sedan models. The ventilator panes on all series have small locking bolts to prevent their being pried open. Concealed door hinges are used on series 39-50 and 61 closed bodies at all points except the lower front door hinge. These hinges are held in place by large size Phillip's head screws. A No. 4 Phillip's head screw driver is necessary for their removal and installation. The hinge mounting holes are slightly elongated, as in the familiar visable type hinge, to permit adjustment of the doors. The two key locking system is retained on all series with only minor changes. On 39-50 and 61 cars, the door locks are separate from the door handles, and the lock cylinders are of the same construction as on 38 and 39-60 Special cars. The LaSalle now has locks in both front doors, as is the case with all Cadillac models. Locking handles are continued on 39-75 and 90 cars. The familiar press button interior door locks are used on all series, except 60S.

4 1939 Service Information The trunk or deck lid handles on all series now incorporates the license plate holder and light. All trunks and deck lids are also equipped with an interior flood light that turns on automatically when the lid is raised. These features are described in the Electrical section on page 12. The series 60 Special does not have running boards; series 39-50 and 39-61 can be ordered either with or without running boards. The removal or installation of running boards can be easily performed m the service station. Frame Frames of new design are used on the 39-50 LaSalle and the 39-61 Cadillac. Fundamentally, these new frames are similar to the previous 50 and 60 frames, as they incorporate such features as the I-beam type of X-member, and side bars curved at the front to encircle the helical front springs. The design of the new frames is indicated by the drawing (Fij;. 1). The LaSalle and 61 Cadillac frames styles have X-members that are heavier than standard to provide greater rigidity. Series 61 convertibles also use a special frame, having additional bracing. One change of interest to service men is the reduction in number of body bolt brackets to four. The body is secured to the frame at seven points on each side, but the bolts pass directly through the frame sidebar flanges at all points except the front and one intermediate point. The frames used on 39-60S, 75, and 90 cars are the same as the corresponding 3 8-series frames, except for minor changes in such items as bumper mounting brackets and mounting holes for assembling the exhaust system and other similar parts. Specifications Fig. 1. Diagram of frame, Series 39-50 and 61. are similar except for the differences in length as required by the different wheelbases, and for the X- member, which is somewhat heavier on the series 61 frame.

The systems used on these two series arc identical, and the following description applies to both. The lower suspension arms and steering knuckle supports have been redesigned for greater strength and for increased road clearance. These arms are steel pressings instead of forgings, and are formed perfectly straight to provide the added road clearance. Rubber bushings are used at the inner ends of the lower suspension arms, in place of the threaded bolt construction. These bushings provide softer riding qualities and insulate the chassis more completely from road shock and noise. The use of these bushings also means four less lubrication points. The lower suspension arms are supported upon stationary shafts bracketed to the frame front cross member, in the same manner as on previous series. The forward and rearward arms are riveted together to form the wishbone assembly, as shown in Fig. 2, and are serviced as a unit, which includes the mounting shaft. In case replacement of rubber bushings is necessary, the two arms can be disassembled by removing the four rivets that secure the spring and bumper pads to one of the arms, and reassembled with screws, nuts, and washers.
