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 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 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.
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.
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.)
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.
Fig. 1196 shows how the lip of the lock washer on the starter drive spring screw should be bent to hold the screw tightly in place. The lip of the washer must be bent upward until it presses tightly against a flat side of the screw head.
New washers should be used every time a screw or spring is changed.
In addition to using the correct parts with each drive, caution owners on the importance of retarding the spark lever when starting so as to avoid the possibility of a back kick occurring. If the first attempt does not result in the engine starting wait and make certain that the engine and starting motor have both come to rest before making another attempt. This will prevent the meshing of the pinion with the flywheel when the engine is back rocking just prior to its stopping.
