Description
⚠️ Important before purchasing:
Fits only wheel motors from 2020 onwards with a metal motor mount. For the 420 model, it fits only the 2020 model year; newer 420s use a different motor type with a plastic mount. Check against the images: metal motor mount without a line extending downwards = fits. Plastic motor mount with a line on the plastic = does not fit.
In that case, choose a different repair kit from the menu instead!
Important installation tip:
The sealing lip of the shaft seal must face outwards towards the wheel; otherwise, it will not fit and will get crushed when installing the wheel hub!
Better than a new original motor – guaranteed
We have developed a repair kit where every component is of higher quality than the Husqvarna original. Moisture ingress is the most common cause of failure for these motors; we solve this with a new shaft seal and a stainless steel wheel axle (optional) that won't rust and damage the seal from the inside.
Unique to Klipparservice: our steel gears feature a bearing-grade bronze bushing for an extremely long service life – something not found in the original.
What makes this kit superior to the original:
- Stainless steel wheel axle (Optional)
Ensures a reliable seal between the axle and the seal over time - Steel planetary gears with bearing-grade bronze bushings – extremely durable; a unique solution from Klipparservice
- Stainless steel screws (Torx and hex) – reusable if needed
- New wheel bearings with rubber seals and shaft seals included
Optional:
- Stainless steel wheel axle – highly recommended if the bearings have failed. The shafts are usually in poor condition once the bearings have failed—and the seal remains effective much longer with a stainless steel shaft. Note: when ball bearings have failed, the shaft is often seized to the bearings.
- Plastic planetary gears – the gears closest to the electric motor wear out quickly if moisture has penetrated. Pins for these are also included.
Fits (metal motor mount):
430X, 435X, 440, 450X, 520, 550 from approx. 2020
