A-13007-E (32-32 C. P.) Head Lamp Bulb

When an owner desires brighter illumination this bulb can he used to replace the A-13007-C, 21-21 C. P. standard equipment bulb in all Model A and Model AA except those manufactured prior to March, 1929. This new bulb gives SO% brighter headlights both for high speed driving and for passing beam.

A-13007-D (21-32 C. P.) Head Lamp Bulb

This 21-32 C. P. bulb is interchangeable with the 21-21 or the 32-32 and represents a compromise between them. It gives SO% brighter headlights for high speed driving, without · increase in amperage for passing beam.

A-18570 (32 C. P., Single Filament) Spot and Stop Lamp Bulb

This higher power bulb will replace A-13465, 21 C. P. single filament in stop lamp and in spot light, with 5O% brighter effect. The spot lamp light beam using the 32 C. P. bulb will reach farther. The stop signal with the brighter bulb makes a more positive stop signal.


In addition to shock absorber instructions contained in the February 1931 Service Bulletin, the following information will prove helpful in servicing Hoodye shock absorbers. When overhauling an instrument always see that the two air vent plugs located in the flange cover are absolutely clean. These vents can be easily removed from the cover by means of a hammer and drift as shown in Fig. 1200. It is a good plan to install new vent plugs when overhauling a shock absorber. They cost but a cent apiece and they insure satisfactory results. The plugs must be in- stalled with the grooved side facing outward. The inner ends of the plugs are then staked to securely hold them in place. The staking operation should be cross-wise to the groove to avoid any possibility of closing the groove.

When assembling the shock absorber be sure the small steel check ball is in place in top of the wing. If the ball has been lost, be certain that the new ball installed is of the correct size. Two different size ball checks are used in production. A percentage of shock absorbers are assembled with a -h” diameter ball. In the remainder a 5/32“ diameter ball is used.

The 3/16” ball is listed under part A-24508. The 5/32“ ball under part A-24505. Extreme care must be used not to confuse or mix these parts. This is important. When the correct ball is used it will be .010 to .014 below the level of the wing.

On some of the earlier type instruments the stationary wing was anchored in place by means of lead caulking; all four corners of the wing were anchored in this manner. If the wing in one of these earlier instruments should become loose it can be tightened by driving BB shot into the small openings at each corner of the wing. A hammer and drift are used for this purpose. (See Figs. 1202 and 1203.)

When assembling the cover to the base see that the cover is screwed down tightly and that the locating mark on the cover lines up exactly with the locating mark on the base. (See Fig. 1110 in the February Bulletin.) This is very important. The cover should be drawn down the same number of turns as was used in removing it.

Never attempt to substitute string packing for the needle valve packing. If the packing is damaged, install a new needle valve assembly. A new reservoir gasket and packing ring should always be used when reassembling.
