Repair of the vacuum pump W140 with a burned-out JOHNSON little engine is to replace Unscrew the torx screws and push the chips here on the contacts of the electric motor. To do this, you need to disassemble the PSE vacuum compressor, unscrew a pair of screws on the case (TORX T20). Next, open the case latch around the perimeter. After removing the bottom of the case, you need to unscrew the electronic board in the unit (TORX T7). After that, you need to push the metal contacts of the chips and nipples from the outside, squeeze the board out of the case. With it, pull the electric motor from the seat.

Separate the lower part of the graphite pump from the metal base of the housing. Perhaps these parts will be glued together with a sealant, then you will need to separate them with a clerical knife. After that, carefully remove from the motor shaft the lower graphite part of the body together with the rotor and the retainer.
