A little preventive maintenance may have helped

[Rene T]

When it came time to break down this year for the trip from FL to NH, the night before we were to leave, I tried retracting my rear Lippert stabilizing jacks. Nothing happened, I tried the wrench and ended up sheering off the pin. I ended up removing some of the bolts for the linkage and tied everything up for the trip home. I just got into it today. I removed the motor and tried to run it off a battery. It made a click when I connected the wires, but it did not turn over. I removed the gear box and it still would not turn over with the battery.  I removed the motor end cap and the brushes looked new. I tried spinning the armature and it still would turn. I removed the armature and found that it had barely seized to the bearing on the other end cap. Once I broke it free, it spun real easy. I reassembled everything and now it runs great.  It had sat for 6 months so I'm thinking some moisture may have gotten in there. From now on, once a month, I'm going to cycle it to keep it freed up.
For those of you with Lippert jacks, it may be a good for you to do the same.

Good tip, thanks Rene

This is good advise for those of us with travel trailers as well if it sits for a while...work the tongue jack to keep it from becoming seized. Of course make sure your stabilizers are raised to avoid damage.

Good advice for anybody with jacks regardless of type/brand.
