NSR Easy Setup Pinions: Adjust Your Transmission Accurately and Effortlessly

The Easy Setup line from NSR was created with a clear philosophy: to simplify the preparation of slot cars without compromising the precision required for competition. These 8-tooth pinions (ref. NSR7008), with a 5.5 mm diameter, are a key component within that system, allowing for quick and repeatable adjustment of the gear ratio.

Each pack includes 2 units.

Function and Performance

The pinion is one of the elements that most influences the character of a slot car: it determines how much top speed you sacrifice in exchange for acceleration, or vice versa. An 8-tooth pinion like this provides a longer gear ratio when combined with larger crown gears, favouring speed on tracks with long straight sections.

The NSR Easy Setup line stands out for the dimensional consistency of its parts, resulting in smooth meshing and vibration-free operation that protects both the motor and the rear axle.

Compatibility

These pinions are designed to integrate into NSR transmission sets and are compatible with the standard axles and crown gears within the brand's ecosystem. We recommend always checking the compatibility with the tooth pitch of your crown gear before installation.

Installation and Preparation

One of the strengths of the Easy Setup range is precisely the simplicity of installation. No complex tooling is required: basic slot preparation tools are sufficient to correctly place the pinion on the axle and adjust the clearance with the crown gear.

• Ensure that the pinion is properly aligned with the crown gear to avoid premature wear.
• A proper fixing point on the axle ensures that the pinion does not shift during the race.
• Test different combinations of pinion and crown gear to find the optimal ratio for the circuit.

Common Mistakes

The most common mistake when changing pinions is not checking the tooth pitch: not all pinions on the market are interchangeable, even if they have the same number of teeth. Ensure that the pinion and crown gear belong to the same pitch standard. Another frequent error is over-tightening the fixing screw on the axle, which can deform the pinion and cause vibrations.

Frequently Asked Questions

How many units are included in the pack?

The NSR7008 pack includes 2 pinions with 8 teeth.

What diameter do these pinions have?

The diameter is 5.5 mm, as specified by NSR for this reference within the Easy Setup line.

What is the difference between an 8-tooth pinion and one with more teeth?

With a higher number of teeth on the pinion (while keeping the same crown gear), the gear ratio shortens: more acceleration but less top speed. An 8-tooth pinion offers a longer transmission, ideal for tracks with straights or when seeking higher maximum speed.

Are they compatible with all NSR crown gears?

They are compatible with NSR crown gears that share the same tooth pitch. Check the technical specifications of your crown gear before combining them with pinions from other brands.

Do I need any special tools to install them?

No. The Easy Setup line is designed to facilitate installation with basic slot preparation tools. No specialised tooling is required.
