Reproduction of Obsolete Parts

From catalogue gap to new part

The process is always the same, whether it is a stub axle or a valve-train gear:

1. Take the pattern – old part, sample or existing drawing
2. Measure and reconstruct – dimensions, material, gear data, hardness profile
3. Create the drawing – CAD in DWG/DXF format, agreed with you
4. Machine – turning, gear cutting, hardening, grinding on our own machines
5. Inspect and deliver – measured, documented, ready to install

You deal with one person throughout. There is no chain of design office, turning shop, hardening plant and grinding shop between whose links responsibility and deadlines disappear.

Examples from the workshop

• Stub axle for the 915 gearbox+

  fine-splined with 43 teeth, large 109.90 mm diameter, matching the original in appearance and dimensions, 1:1 interchangeable. The original has long been unavailable from the manufacturer.
• Nardella stub axles+

  for gearbox types 901, 904, 908, 910 and 917.
• Steel differential housing for the 356 gearbox+

  the answer to uprated engines that overwhelm the original housing.
• Gearbox shafts+

  for the 904 with slip-fit second gear and for the 930 Turbo.
• RSR spray-oil cooling+

  the factory motorsport solution, remanufactured.
• Sprockets and gears for the valve train+

  for classic engines, from sample or drawing.

Material and heat treatment

A reproduction is only as good as its material. We select steel and heat treatment to match the function of the part – high-strength alloys for shafts and stub axles, case-hardened gear teeth, ground functional surfaces. On request the execution is documented in a measurement report.

A note on classification

Our reproductions are not original manufacturer parts, and we have no commercial affiliation with any vehicle manufacturer. Type designations are used solely to describe fitment. That, incidentally, is exactly why this work exists: parts no manufacturer supplies anymore have to be made somewhere.
