Ball Bearing Oil Seal Set Puch E50 – For the old model (1-bearing shaft)

Is a motor revision due for your Puch Maxi? If you ride the legendary E50 engine of the old generation, this complete set is exactly what you need for a durable and leak-proof drive. The set contains all important ball bearings and oil seals (shaft seals) specifically tailored to the housing dimensions of the old model.

Especially with the old E50 engine, the precise fit of the bearings is crucial for smooth engine operation. The branded ball bearings included in the set offer high-speed resistance and minimize friction in the crank drive as well as in the transmission. The matching oil seals ensure that no transmission oil enters the crankcase and your engine does not draw in false air – thus maintaining full power and allowing your moped to be perfectly tuned again.

Tips for installation: A motor revision requires clean work. Heat the engine casing evenly before inserting the bearings (e.g., with a hot air gun), while ideally cooling the bearings in the freezer. This way, they can be inserted into the bearing seat without force. When installing the oil seals, be careful not to damage the sealing lips; a little grease on the lip helps prevent them from running dry on the first start. Before reassembling, make sure all the spacers are back in their place to correctly adjust the axial play of the shafts.

Care instructions: After installing the set and reassembling the engine, it is important to fill in fresh transmission oil. We recommend changing the oil after the first 100 to 200 kilometers to remove any installation debris. A leak-proof engine thanks to new oil seals is the best insurance against starting problems and unsteady idle.
