Central support for pinion press

The support every preparer needs for pressing pinions without losing the bench adjustment

The Slot.it SISP30 Central Support for pinion press solves one of the most common setbacks in the workbench: the need to disassemble the motor from the bench every time a pinion needs to be fixed or removed. With this support, the process is carried out directly in its position, saving time and avoiding unnecessary handling that can affect the previous adjustment.

Function and performance

Its main function is to act as a central support point during the pressing operation, keeping the motor-bench assembly stable while working with the pinion. This allows the necessary force to be applied in a controlled manner, without the risk of damaging the motor shaft or displacing the already adjusted assembly.

Compatibility

• Designed to be used alongside Slot.it extractors SP20 and SP21.
• Intended for use with motors mounted on the bench, without the need for prior disassembly.

The support does not include the SP20 or SP21 extractors. They must be purchased separately.

Assembly and preparation

The correct use of the SISP30 is straightforward: it is placed as a central support before applying the corresponding extractor (SP20 or SP21). By keeping the shaft in position during pressing, a precise seating of the pinion is achieved, reducing the possibility of subsequent play or misalignments. For preparers who frequently work on transmission adjustments, this tool significantly streamlines the process.

Common mistakes

• Attempting to press the pinion without support can damage the bearings or the motor shaft.
• Do not confuse this support with the extractor: the SISP30 is the support element, not the extraction/pressing tool itself.
• Always check that the extractor used (SP20 or SP21) is suitable for the shaft diameter being worked on.

Frequently asked questions

Can I use the SISP30 without the SP20 or SP21 extractors?

No. The SISP30 acts as a central support and is specifically designed to work in combination with the SP20 or SP21 extractors. Without them, it cannot perform the pressing function on its own.

Are the SP20 and SP21 extractors included in the pack?

No. The SISP30 is sold independently. The SP20 and SP21 extractors are sold separately.

What is the purpose of fixing the pinion without disassembling the motor from the bench?

Disassembling and reassembling the motor involves readjusting the entire transmission geometry (pinion-crown play, axle height, etc.). By working with the motor in its position, the previous adjustment is preserved, saving time on the workbench.

Is it compatible with motors from other brands?

The available information links it to the Slot.it tool ecosystem (SP20/SP21). To confirm compatibility with motors from other brands, consult the technical specifications of the corresponding extractors.

The Slot.it SISP30 Central Support for pinion press is an essential workshop tool for slot car enthusiasts and race preparers. It allows pinion installation on the motor shaft without removing the motor from its mount, preserving previous setup adjustments. Compatible with Slot.it SP20 and SP21 extractors (sold separately). A precise, time-saving solution for slot car tuning and maintenance.
