Statorwerk · specialized motor rebuild log

Specialized motor rebuild — case studies from the bench.

Every drive unit that crosses the bench leaves a rebuild line. Brose motor rebuilds on the Turbo Levo — Gen 1, Gen 2, and Gen 3 — and the Turbo Kenevo, covering the real failure modes we see on out-of-warranty Specialized bikes.

Intermittent power cutouts on the Brose 1.3 in a Gen 2 Levo. Water-damage recovery from a creek crossing on a Kenevo. Bearing-swap rebuilds on early Brose 1.2 Gen 1 motors that have started to grind. Each card below is a bench note: the symptom in, the work we did, and what shipped back.

Rebuild log

Three Specialized motor rebuilds we’ve already put back on the trail.

The owner fills each card in after a rebuild leaves the bench. Each line is the symptom they booked against, the repair steps, and what came back on the warranty sheet.
