Porsche 902 Gearbox Rebuild

Rebuild to factory specification, parts from our own production, housing restoration

The four-cylinder brother of the early 911 shares its gearbox family — and its parts supply problem. We rebuild the 902 gearbox to factory specification and remanufacture what the market no longer supplies.

What we do on the 902 gearbox

Rebuild to factory specification
complete stripping, inspection of all bearings and synchromesh, ring-and-pinion setup, test-bench run.
Parts from our own production
gear parts, shafts and dog rings — made individually instead of only available as expensive pairs.
Housing restoration
water blasting and magnesium pickling in-house — returns old housings to the original, slightly mottled factory finish.

Typical problems this solves

Parts are marketed almost exclusively for the six-cylinder 911
Crunching gears and worn synchromesh

Why inquire here

To us the 902 is no oddity — it is part of the same gearbox family we have rebuilt for decades: same measuring equipment, same setup procedure, same test bench.

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
