Landing Gear Motor
Has anyone replaced their landing gear motor, and can you replace it with a more powerful one? Mine is intermittent while extending the legs under load. When it stops, I get the manual crank and make a couple of turns and the gear works again. I have tried lubing with oil, but no joy. I have a 2007 3075RL. I do not think it is the switch, because using the crank makes it work again.
Tks, Roger--xgboy.

Does the motor go completely dead or does the gears sound like they are in a bind? If it is going completely dead it sounds like the same effect you get when the auto reset breaker acts up on the slides. My unit does not have an auto reset on the landing gear system but who knows if the Amish electricians didn't feel generous the day of your build. Jim

You may have a electrical (battery) problem, not a mechanical one. Go for the easy solution first.

As Mike pointed out, it's more likely electrical - unless you've bent one of the legs. If you only notice this while on battery only, your battery could be weak. A common upgrade for folks is either replacing to stock 40 amp breaker with two 40 amp breakers wired in parallel or replacing it with a 80 amp breaker. The advantage to the two 40's is they give you 80 amps at a lower cost.

To answer your question, I replaced mine. Ventura. The motor was the same, but I replaced the gear box along with the motor. The OEM gear box was plastic, the new gear box is steel. Ventura has an excellent web page with drawings, part listings and prices. As indicated above, check legs for binding, use a level. In my case, I had a bent leg I did not recognize, and over time, it destroyed the gears in the landing leg. I had to replace the leg as well because of that.

Roger,
Next time it happens, wait 10 minutes and try again without using the crank. I if it works, it is the circuit breaker.
Tom wrote, two 40 amp breakers wired in series, I think he met to say parallel not series.
I replaced my 40 amp auto reset breaker with 100 Amp Car Audio CB, not had any more problems. If it ever pops, you have to manually reset, so you know you had a problem.

Dang it! John you are 100% correct. After taking 3 years of electronics, I knew it was parallel, but my fingers typed series instead. Correction made!

I thought auto-resets were on slides, not landing gear?!!

Our 2007 model only had the 40 amp blade type fuse (some even had 30 amp blade fuses based on past forum postings) in line with the landing leg motor. It sounds like it may be a bent leg since apparently you are forcing it to work again with the manual cranking. I think the advice on checking the battery is step one however. With regards to the landing gear motor, when ours went out on the 2007 model, it completely died, no warning, no in-between, just stopped working completely, so I am leaning towards something being wrong other than the motor itself. Does it do the same thing with shore power and without, that may provide a clue as to the battery status.

One of our RV gurus upgraded his low amperage fuse to an 80amp and it solved a host of issues. I have a new 80 amp that you can have. This applies to anyone else that might want to upgrade, 1st to PM me gets it.

That is what I thought Chris. That is what prompted me to mention generous amish electricians. Like they threw in a bonus auto reset breaker. Units not here so I can't confirm but I'm sure my landing gear circuit only has the blade type fuse in it. Jim

Thanks to all who replied. I have two new 6 volt batteries, and it will quit on batteries or shore power. I will check for a bent leg and check to see if it has a circuit breaker and replace.
Happy Trails, Roger

I see comments about 80 amp resetable breakers.
I feel the hydraulic slides and landing gear wiring have been confused in this thread.
I believe the hydraulic slides have been upgraded from 50 amp to 80 amp or using two 40 Amp in parallel.
My landing gear was fused for 30 amps. The switch was rated at 20AM.
I have replaced my 30 amp fuse with a mental cased 30 amp resettable fuse.
Changing to 80 amps on the landing gear motor is an excessive upgrade in my opinion. I suggest you talk to Ventura before you go that high.

OK Chris, I give up! I should have stayed in bed or ignored this post completely. You are correct, I was thinking about slides and answering a landing gear issue. XGBOY, please ignore my posts.
I'm going to shut the heck up now before I do more damage.
