There are several variations of slot car chassis that were manufactured and used from 1962 to 1969. The first chassis ever used in production is what I call the STANDARD¹ chassis. This STANDARD chassis was utilized in the early issue (PB) PAINTED BUMPER², as well as, the early versions of the (CB) CHROME BUMPER³ Atlas slotcars. ¹²³I am pleased to say that these terms have been part of the commonplace slotcar lexicon ever since I coined them several decades ago.
As can be witnessed in the above examples, the STANDARD
unit in this
was designed to permit a truer scale reproduction of
slot cars of this size.
With proper care and maintenance, your
should give you countless hours of satisfactory running.
Early Atlas slotcar STANDARD chassis operate by a 5 pole 12 Volt D.C. motor geared to the rear axle. Chassis that have been in storage for decades should be relubricated and test driven to assure smooth operation. Each slot car should be operated at full speed to fully seat carbon brushes and break in the motor bearings before top performance can be expected.
To replace worn brushes, unscrew the Brush Screw part #M108 and pull on the end of the Motor Frame part #M107. The Brush will pull out of the Brush Spring for an easy replacement. The Brush Spring part #M107 has a closed end that goes into the end hole of the Brush Screw. Push a new Brush into the Brush Spring and screw the unit back into the Motor Frame. It is always best to replace BOTH brushes at same time. Your motor will need a break in track run to fully seat the new brushes before top performance can be expected. If it becomes necessary to take the motor apart, remove the Brushes first and the Spur Gear next. Then firmly grasp the base of the Motor Frame between 2 fingers and hold the End Plate and Field Clip with other hand. Pull firmly to separate these parts as demonstrated in the following schematic.
A drop of oil is needed on the inside shaft bearing on the front of chassis and in oil channels as shown in exploded chassis assembly drawing will give smooth operation.
HINT: Use dab of Petroleum Jelly - Vaseline® - on end of motor shaft bearings. Do NOT use oil on motor shaft.
Keep slot car track roadway clean by wiping with dry soft cloth. Static electricity will attract lint to axles and gears causing improper performance and possible damage. HINT: For best results do NOT run any slot car set directly on carpet.
