Slot.it's new version of its high-quality professional extractor/press makes it easy to install or remove pinions onto/from any 1/32 electrical motor. The frame is very strong yet surprisingly light. Designed for use with pinions ranging from 5.5mm to 7.5mm in diameter.
The Slot.it extractor/press consists of:
Main body (1) entirely made in plastic: designed to work with electrical motor for slot cars, from the most common short can to the more sophisticated, double long transmission shaft 4WD motors.
Counter bushing (6) made of brass which must be screwed onto the lower inside part of the main body, before using the too
This bushing performs two very important functions:
- center the double shaft motor perfectly by means of the axle housing hole.
- keep all those motors that are not equipped with the double shaft centred and, at the same time, safeguard the inner bushing of those 'long can' motors motor that do not have an axle stub protruding from the can.
Special steel extraction plate (5) fitting in the relevant housing in the main body (1) to extract pinions. It's very resistant, and comes with a very thin eyelet to be inserted between the motor and the pinion: only 0.7 mm. This allows safe extraction for those pinions located very close to the motor case without causing any damage.
Multifunction brass tool (2) which, depending on the operation to be performed, must be inserted in the main body with the plug (steel, interchangeable, Ø1.9mm in order not to damage the pinion hole) downwards, in case of the extractor, or the pinion housing downwards, in case of the press. The pinion housing for this element were designed to house pinions with a diameter ranging from 5.5mm to 7.5mm without damaging them.
Steel plug (3) : the tool comes with two steel interchangeable pins, of 1.4mm and 1.9nn diameter, for pinions with 1.5 and 2mm hole, secured to the brass tool by means of an M3 grub screw (4)
Advancement screw (7) whose upper part comes with an ergonomic plastic knob (8), while the lower part is designed to couple perfectly with the tool's bevel, to reduce friction and to allow the press to operate perpendicularly without play. How to press a pinion.
Remove the steel extraction plate from the main body.
Unscrew the knob screw (7,8).
Slide the tool along the main body rails, the proper pinion housing facing downwards.
Position the motor in a way that its case (with double shaft motors, the shaft which is not involved in the operation) in the counter bushing (6).
Position the pinion in its housing on the tool and place the assembly next to the motor axle
Screw the knob screw (7,8) forward until the tool and the pinion make contact..
Start (by means of the handle screw) to insert the pinion in the motor axle.
Once the operation is completed, loosen the handle screw and extract the motor.
How to extract a pinion : Loosen the knob screw
Insert the multifunction tool with the proper plug (1.4 or 1.9mm) downwards and place it on the upper part of the extractor.
Insert the steel extraction plate with the groove facing the tool
Insert the motor so that the eyelet sits between the motor case and the pinion, facing the plug.
Start fastening the handle screw until the pinion is fully extracted
Upon completion, unscrew the handle screw and extract the motor.
