Please refer to Fig. 1192 in the June Service Bulletin and change the width of the slot shown in A-11357-BR starter drive service sleeve, from 3⁄4″ to 1⁄2″.
year: 1931
SUPPORT SPRING STRENGTHENED
To still further increase the strength of the A-6031 engine front support auxiliary spring, a flange has been added around the hole for the engine support stud and a bead added next to the hole. (See Fig. 1224.) This type of construction materially increases the strength of this part.
Oil Grooves in Main Bearings
After rebabbitting a cylinder block be sure to form oil grooves in the main bearings. (See Fig. 1226.) K. R. Wilson furnishes a tool for this purpose.
DE LUXE COUPE BACK WINDOW NOW ADJUSTABLE
The back window in the De Luxe Coupe has been changed from a stationary window to a window which can be raised or lowered. This change is now standard equipment on the De Luxe Coupe and can be obtained as special equipment at extra cost for those desiring it in standard coupe bodies. When a rumble seat is installed in a standard coupe the adjustable back window will be supplied at no extra charge. It will of course be necessary for the dealer to notify the Branch as adjustable back window installations must be made at the Branch.
Due to the amount of labor and expense involved it would not be practical for dealers to attempt to replace a stationary window with an adjustable window in old coupes.
TWO DESIGNS OF TRUCK REAR HUBS
Truck rear hubs AA-1113-F2 and AA 1114-F2 are now being used in 100% production. In these hubs the bearing sleeve is made integral with the hub. This construction eliminates the AA-1236-C rear hub sleeve and the A-23225 sleeve retainer rivet. The AA-1113-F2 and AA-1114-F2 hubs can be used interchangeably with the AA-1113-Fl and AA-1114-Fl hubs which have the sleeves installed.
TOP DRESSING
Top dressing should never be applied when a top is new, it should be applied only after the top material has become very dull, checked or cracked. It is also important that the correct top dressing is used with rubber and pyroxylin coated tops. Use M-255 for Pyroxylin coated tops only, Use M-255-B for Rubber coated tops only.
A-46116-R LOCK CYLINDER OBSOLETED
A-46116-R lock cylinder and key assembly has been obsoleted. If calls are received for this part after present stocks are exhausted, supply A-46123-E lock cylinder and A-11586-C key. The key can be cut on your key cutting machine and the tumblers in the lock cylinder then fitted to the key.
IDLER GEARS USED IN ELECTRIC WINDSHIELD WIPERS
To assist dealers in identifying the various fiber gears in the electric windshield wipers formerly used on the Model A, details of these gears are shown in Fig. 1207.
USE CARE IN STORING HEADLAMP REFLECTORS
Headlamp reflector surfaces that are exposed to sulphur fumes will turn the reflectors black. Rubber fumes from tires, etc., will also tarnish reflector surfaces. If any of these parts should become tarnished, they can be easily cleaned by dipping a soft cloth (preferably cotton flannel) into dry lamp black and rubbing the reflectors for a few minutes until their bright appearance has been restored.
LENGTH OF REAR FILLER BLOCK INCREASED
To still further increase the strength of the floor side sill rear filler block A-35081-R.H. and A-35082-L. H., used on Tudor and Touring Cars the length of these blocks has been changed from 3″ to 6″; the length of the bevel on the edge of the block has also been changed from 1 3⁄8” to 4 1⁄8”. (See Fig. 1208.)
CHANGE IN DOOR LOCK ASSEMBLIES
A change has been made in the location of the screw which fastens the remote control connecting link to the door lock unit. This change has been made in all door locks used on the following type bodies:
160A, Band C. Sedans
190A Victoria
79B “A” Panel Delivery
225A “A” Panel Delivery Drop Floor
85B “AA” Panel Delivery 131″ W. B. The old design locks A-161100-A, A-191100- A, A-161101-A, A-191101-A, A-162100-A, A-80055-B, A-162101-A, A-80056-B, will not be carried for service. If, after present stocks are exhausted, you receive calls for any of the above locks, supply the new design and redrill the screw hole for attaching the lock to the inside door panel so that the hole will be exactly in line with the clinch-on nut. Drill a 3⁄8” hole 27/32” below and 1 11/16“ forward from the present screw hole. (See Fig. 1187.)
The following are the symbol numbers of the new locks used on the bodies listed in the opposite column.

USE OF MILEAGE TESTER ON CARS EQUIPPED WITH NEW COWLTANK
To install the mileage tester on cars equipped with the new design cowl tank (see page 560 May Bulletin) it is necessary to use two special fuel pipes. One of them is a short curved pipe, the other is a long straight pipe. A sleeve is soldered to one end of both of these pipes so they will fit into the rubber hose which is attached to the tester. To install special pipes, first shut off gas and remove the regular A-9240C pipe. Then insert sleeve end of curved pipe through speedometer cable hole in dash and connect opposite end of pipe to gasoline valve assembly on front of dash. In the same manner insert the sleeve end of the straight pipe through the speedometer cable hole in dash and connect the opposite end of the pipe to the carburetor. Remove the fittings from both ends of the rubber hose which extends from the mileage tester, and slip the hose over the sleeve ends of both pipes. Turn on gas. This completes the installation. (See Fig. 1188). The price for the complete set of two pipes is 25c net. Orders should be placed direct with your Branch.
