Greenhouse Vent Motor

greenspun.com : LUSENET : Countryside : One Thread

Hello Countrysiders. I'm in desperate need of a Lord & Burnham Safe Return Damper Motor Model# 311B0-420-V or any type of rebuild kit. Does anyone have any other suggestions for opening and closing the automatic greenhouse vent?

Also, something is eating on my tubers of Jerusalem arthichokes. Any idea what that might be? It looks like some sort of a worm, it leaves little "tunnels", but I have not seen it on any of them.

I imagine the damage on the Jerusalem artichokes is being done by some form of root maggot. Pretty discusting eh?

I can't help you with a rebuild kit for the motor, but any good electic motor repair shop should be able to rebuild it or get a replacement for you.

The W. W. Grainger Company sells about every electrical motor that you can imagine. It's web address is http://www.grainger.com

Grainger is a very good place to look and also a company called Johnston supply. Check for a local refrigeration supply house also. It is unlikely in this day and age to find a motor winder to rebuild it. Most fractional hp motor are disposable anymore. When calling and asking a supplier, make sure you have the motor voltage, horsepower, rpms, rotation, and frame number. This info is usually printed on a spec. plate on the motor itself so you might have to remove it to read it. The OEM, (original equipment manufacture), part number helps too but with the other info, a much less expensive equal replacement motor can often be found. Frequently manufactures use very common parts, put their own number on it and charge three times as much as you can get the generic part for, so it pays to shop a little sometimes.

Probably I am too late to help, but I have one of these things in my attic, and it died recently. I removed it and starterd looking for a replacement, and came across your query. What I found is that the motor and mechanicals are okay, but the electrical wiring to the motor was ruined by moisture and oxidation over time. All I had to do was open up the case and replace the main line wires that connect to the motor wires. Getting the case open is a little tricky. I had to make a tool to hold the nuts in place, which is essentially a fork, while turning the screws with an ordinary blade screwdriver. If you start with a second screwdriver that is appropriate for the screw-heads, then use a Dremmel saw to remove material from the center of the blade, then you will have a forked tool that will work on the nuts. The oiling tube has to be bent to allow the case to separate. Add oil while you are at it. Hope this helps.
