The 912 Rotax Carburettor Piston Holder is a specialist throttle piston spanner designed to securely hold the carburettor piston in place on Rotax 912 series engines while the engine is off, allowing safe and easy removal of the needle.

Unlike metal alternatives, this tool features a non-marring design that protects the piston surface from scratches or damage during the procedure — essential when working with precision aviation components.

Manufactured using high-quality engineering resin via professional 3D printing , this tool offers excellent dimensional accuracy and rigidity, ensuring a reliable fit every time. The resin material is selected for its strength and resistance to the thermal and mechanical stresses typical of workshop use.

Key Features

• Designed specifically for the Rotax 912 series carburettor
• Non-marring construction — protects piston surfaces
• Produced in high-quality 3D-printed resin for precision and durability
• Facilitates needle removal from the carburettor
• Compact and lightweight workshop tool

Why This Tool Matters in Practice

At the centre of the piston sits a deeply recessed screw secured with thread-locking compound. To avoid stripping it — particularly important given the piston's soft aluminium construction — the assembly must be heated before attempting removal. This makes heat-resistant gloves essential: without them, burns are likely and grip is severely compromised, causing the piston to rotate freely instead of staying fixed. This holder solves both problems at once, giving you the secure hold you need to work safely and effectively.

An indispensable addition to any Rotax 912 maintenance toolkit, this holder simplifies a task that would otherwise risk damaging sensitive carburettor components.

Shipping via courier could not be possible in some very rare cases and therefore it will be replaced with other shipping method unconditionally (usually via registered mail).
