Jonathan Pounsett Posted February 14, 2022 Share Posted February 14, 2022 I’m looking for a ventilation fan for a Manta B if anyone can help Happy to pay the going rate for a good working one. 🤞 Link to comment Share on other sites More sharing options...
Trooker Posted February 14, 2022 Share Posted February 14, 2022 You may be aware but just in case you don’t find one https://mantaclub.org/forums/topic/43816-heater-motor-bearing-replacement/ is a great write up of repair/refurb. I ordered the recommended bearings yesterday as mine failed the other day but thought it was just a slightly dodgy plug/socket. On Saturday I discovered that the wires had become brittle/broken on the blower side of the 3 pin plug so will need to source that too. Note that the black is constant +12v & the switch inside grounds the resistor or the motor. 1 Link to comment Share on other sites More sharing options...

Jonathan Pounsett Posted February 16, 2022 Author Share Posted February 16, 2022 Thanks to @Exclusive Opel’s tutorial I now have a fully functioning fan. Thanks to to @Trookerfor pointing me in the right direction. Knowing the tabs are likely to break made me extra cautious but I did manage to gently pry them open without any damage. I cleaned up this bearing without removing it using a rolled up piece of fine wet and dry. I pressed the other bearings out through the retaining spring clip and then levered out the clip through the spindle hole. It was probably possible to clean this bearing in-situ too - but it’s out now. Retaining clip was reused, pressed into place with a suitably sized socket. Whilst it was all apart I re-sprayed the casing and cleaned up the armature and bearing surfaces. Finally lightly oiled and reassembled with a new retaining washer. Ingredients; spray paint and a single retaining washer. Time taken; 1 hour. 3 1 Link to comment Share on other sites More sharing options...

Trooker Posted February 16, 2022 Share Posted February 16, 2022 Looks great, well done, mine’s still in bits on the bench, busy evenings but the bearings @Exclusive Opel recommended arrived today. 👍 1 Link to comment Share on other sites More sharing options...
