Cleaner repair consists mainly in editing deformed rods and levers or replacing them with new ones. It is recommended to replace a defective gearmotor with a new one. Of the repair work on the gearmotor, only the replacement of the gear of the gearbox, cleaning the collector and adjusting the limit switch are allowed.
To remove the cleaner, remove the brushes with levers, open the hood and disconnect the wires from the battery, the cleaner motor gear and from the heater fan. Remove the cover of the mounting block and remove the relay from it. Remove the heater fan. Loosen axle nuts (fittings) levers and remove washers with leveling gaskets. Unscrew the drive bracket bolt and remove the cleaner. If necessary, remove the gearmotor from the bracket on the workbench and disconnect the rods.
Install the cleaner in reverse order.
