We now offer an upgrade for all Bosch Gen 4 motors.
Not sure about your engine model? Identification of bearings
The engine is dismantled and the entire crankshaft assembly is removed. Self-lubricating plastic crankshaft support bushings are fitted to the torque tube to stabilise the crankshaft clearance.
The original torque tube sealing ring is removed and an Oilite sealing bronze bag is fitted to ensure maximum support for the crankshaft.
This stops the crankshaft from vibrating and improves sealing.
After the oilite bag, we install a shaft seal with the lip facing outwards, preventing water from entering the crankshaft and torque tube area.
This prevents rusting of the crankshaft bearing surface, premature failure of the crankshaft support bushings and internal damage to the printed circuit board (PCB) and all other components.
The left crankshaft bearing is replaced with a double-sealed bearing to prevent water from entering or passing through this bearing. Waterproof long-life grease is packed between the outer bearings and the motor covers.
This will help prevent water from accumulating in these areas and running off into the outer bearings.
We also remove the circuit board and add a silicone coating to the seal of the connectors.
A silicone sealant is also added to the engine cover gasket to prevent water from corroding the sealing surfaces of the magnesium engine cases.
Finally, we treat and coat the pins on the electrical connectors of the motors to limit corrosion.
