DT-CHK-002 CHECK STEP 2 - Inspect bearings and radial shaft seals

Tools:

• No tools required.

Procedure:

1. Inspect the rotor shaft and bearing seats for scoring, corrosion or damage.
2. Inspect the wave spring washer for deformation or damage. Replace if damaged.
3. Inspect the housing lid and O-ring contact surfaces for cuts, scratches or corrosion.

CAUTION

🗑 Do not reuse the removed Bearing 6202 ZZ (013010001) bearings, Radial shaft seal 15x25x5 (017020001) or O-ring 70x4 (017010001). Always install new bearings, seals and O-rings during assembly.

TODO

Define the acceptance criteria for shaft/bearing seat wear (e.g. maximum scoring depth, corrosion limits) and the wave spring washer damage tolerance.
