Recommendation of Replacement Landing Gear or Motor on 2006 Keystone Raptor

Question:

I have a 2006 Keystone Raptor 3712ts and the motor was replaced on the landing gear 10-28-12. The landing gear will not go up or down. It sounds like a gear stripping out. So I have removed the motor and the reduction gear box. Then I opened up both of them and I found all gears to be in good shape. The grease was getting thin and old and was replaced. What would be the next step I need to take? Is there a easy way to tell which jack is the bad one and how do I do that? What kind of grease do I need to replace what has worn out, is it wheel-bearing grease?

My recommendation would be to disconnect the motor and gearbox, as well as the strut that connects the two drives. Try to manually actuate each jack to see if they'll operate manually. Depending on the manufacturer of the landing gear, there might be replacement gears or the jacks might be individually replaceable.

Many electric landing gear sets use white lithium grease for the gears and drive screw. If you are looking for grease to use on your current set, I recommend using our LubriMatic White Lithium Grease, # L11354.
