SERVICE AND ADJUSTMENTS

Engine Tune-Up

Occasionally your serviceman will recommend an engine tune-up. The frequency of tune-ups depends almost entirely on the amount of driving and the type of driving you do. When you purchase a tune-up, we recommend that you request at least the following operations:

1. Check the manifold heater valve for free operation.

2. Clean and adjust spark plugs; install with new gaskets.

3. Clean carburetor air cleaner.

4. Clean fuel pump bowl and strainer; install with new gasket.

5. Clean inside of distributor cover, cable terminals, and sockets.

6. Tighten cylinder head cap screws to recommended tension.

7. Adjust fan belt.

8. Remove and clean carburetor choke thermostatic control. Replace with new gasket and adjust, if necessary.

9. Check and set ignition timing.

10. Adjust carburetor idle screw with engine at normal operating temperatures.

11. Adjust idle stop screw to produce engine speed corresponding with 8 miles (13 km.) per hour road speed in high gear.

Adjustments and Other Service

Carburetor Adjustment for High Altitude The carburetor is carefully calibrated to provide efficient operation. Studebaker dealers are acquainted with the adjustments which are needed for high altitude operation.

Brake Adjustment The self-adjusting brakes on your car are self-compensating for lining wear and require no adjustment. They are properly set at the factory.

With each application of the brakes, however, the linings wear and, after a time, new linings should be installed to provide the maximum braking area and to avoid damage to the brake drums. When the lining needs replacement, the self-adjusting feature ceases to operate. When this occurs, the brake pedal free travel will increase and the driver is warned that the brakes need relining. If your brakes do not operate satisfactorily, see your Studebaker dealer.

Clutch Pedal Travel Adjustment Clutch pedal free travel is the distance the pedal moves forward before resistance of the release mechanism is felt. When the free travel is greater than one inch (25,4 mm.) or less than one-half inch (12,7 mm.) adjustment should be made by your Studebaker dealer.

The Hill Holder (on cars so equipped) should be checked and adjusted if necessary whenever the clutch pedal travel is adjusted.

Fan Belt Adjustment To insure efficient fan, water pump and generator operation, it is important that the fan belt is not over-tightened. Any readjustment should be performed by a Studebaker dealer.

Front Wheel Camber Adjustment Camber adjustment is properly set at the factory ½° greater on the driver’s side of the car than on the other side. Should a front end alignment check reveal need of camber readjustment, it should be set as nearly to ¾° on driver’s side and ¼° on the other side as possible. In any setting, the driver’s side camber should be ½° more than the other side.

Body Drain Holes All drain holes should be kept open to prevent accumulation of water.

The door drain holes are easily cleared with a pen-knife or other flat instrument which can be inserted in the holes and run back and forth a few times to loosen any congestion.

Body drain holes should be cleaned by the serviceman.
