I had to replace one of my Happijack drive units recently. I contacted the company and requested to buy just a replacement electric motor as the gear assembly etc was fine, just the motor was seized. There was no reply from them, the silence was deafening!! Too bad they seem to be the only company producing these motor assemblies, some competition might help! I managed to get the motor apart after soaking the two through bolts for 3 weeks in penetrating oil to see what was going on with the corrosion issue. It was amazing how badly corroded the inside was. I did get the motor working again and it will be my backup unit when one of the other 3 seizes up!
If I could figure out how to post a photo to this post it would be great.
