Saxo T4 piston 79mm TU5J4

Forged piston from the Citroën Saxo T4 rally car engine TU5J4. This 3D scan is specifically designed for engine builders, fabricators, and DIY engineers who need an accurate 3D spatial reference to design custom high-compression pistons, evaluate combustion chamber valve clearances, or model upgraded engine internals in CAD.

Ideal Applications 

• Custom Piston & Engine Design:
  Reference the crown profile, valve pockets, and pin boss geometry to design custom forged pistons or optimize compression ratios.
  
  
• Clearance & Valve Pocket Checks:
  Evaluate intake and exhaust valve clearance in 3D CAD when running high-lift camshafts or modified cylinder heads.
  
  
• 3D Printing & Prototyping:
  Print 1:1 scale mock-ups to test physical fitment, deck height, and rod assembly clearance before expensive CNC machining.

Licensing & Usage Terms

• Personal Use License: Non-exclusive license for private projects, one-off custom fabrications, and personal R&D.

• Commercial Use License: Required if using this scan data to produce commercial components or kits intended for resale.

• Redistribution Prohibited: Re-selling, sharing, or publicly distributing the .STL file or derivatives thereof is strictly prohibited regardless of license type.

⚠️ Disclaimer & Fitment Notice

Spatial & Partial Data Reference Only: This 3D scan is a partial dataset of a physical steering pump captured in its as-manufactured state. Due to casting variations, production revisions, and minor wear on reference parts, all critical mounting hole centerlines, thread pitches, and port dimensions must be physically verified prior to final CNC machining or component production.

Power steering systems are safety-critical. Structural and fluid-system evaluations remain the sole responsibility of the builder/engineer. The seller assumes no liability for components or bracketry fabricated using this reference data.

Disclaimer: All brand names, trade names, or vehicle model designations (such as Peugeot, Citroën, 106, Saxo) are used purely for compatible vehicle and chassis identification purposes. This product is an independent aftermarket digital reference file and is not manufactured, endorsed, or affiliated with Stellantis N.V. or its subsidiaries.
