M20R Posted February 11, 2019 Report Share Posted February 11, 2019 Today I turned on the Aero Safe standby vacuum pump to test the system which I do on a regular basis. The pump would not come on and then I could smell an electrical smoke. I opened the side panel and the electric motor on the pump was very hot and the wires had turned black. The motor appears to have seized. For some reason the circuit breaker did not open. I checked the aero safe web site and I could not find out whether they sell just the motor. Does any one know if anyone repairs these motors or where to find a replacement motor. Everything is electric except the artificial horizon. I was planning on putting in the King KI 300 but I don't think they will ever be available. Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 11, 2019 Report Share Posted February 11, 2019 There is a discussion around here regarding the PVC tubing that was used on some installations in later Long Bodies.... It is possible that you may have the Bad tubing? The plasticizer came out of the tubing’s PVC material, possibly contaminating the pump? this is a bit of a stretch, since there should be a rubber coupling to separate the vac pump from the motor... Either way, an electrical overload should have triggered a CB to trip. http://www.aerosafe.net/ Got any pics? An Aspen E5 might make a better alternative...

gsxrpilot Posted May 1, 2019 Report Share Posted May 1, 2019 Yep, I've got one as well. 24v. Make an offer, consider shipping, they're heavy. Quote Link to comment Share on other sites More sharing options...
rgpilot Posted May 2, 2019 Report Share Posted May 2, 2019 The vinyl tubing from the pump collapsed in my 2003 Ovation. Replaced it with upgraded tubing. Quote Link to comment Share on other sites More sharing options...
Oldguy Posted May 2, 2019 Report Share Posted May 2, 2019 Regardless of what you decide, I would recommend having someone check the wiring to see how badly damaged it is from the switch back to the pump. Blackened wiring might fall under the "not airworthy" category. Quote Link to comment Share on other sites More sharing options...
Florg Posted March 10, 2020 Report Share Posted March 10, 2020 I'm reviving this post as my standby apparently failed as well (getting power but nothing runs). Anyone still have a 24V standby they'd like to get rid of? Thanks, Brett Quote Link to comment Share on other sites More sharing options...
