Posting this in the Travel Supreme forum since, well, it's on my ME "Unikorn" Toy Hauler. Yes, I know all (as far as I know) other TS have Leveling Systems, not LCI or Lippert. Still, the title should let others with LCI/Lippert systems find the info.
I replaced the original jack hydraulic system (it tapped the coach hydraulics at the power steering...so no 'manual retract' and a leak meant you could not drive!) with a LCI/Lippert pump/reservoir. The jack legs were/are PowerGear, now Lippert. See previous post on that install.
This past weekend after being parked for four days, I hit the retract and all seemed well, except the "Jacks Down" kept momentarily coming on. Checked the jacks and all were up (they are power up/down; no springs), so pressed towards home. After noticing that each momentary flash was accompanied with a momentary voltage drop, it became apparent the system was trying to get the 3000psi "UP" pressure by cycling the pump...I thought. Eventually, the light went steady followed by the alarm. I pulled into a parking lot and found a VERY hot motor in the compartment. OK...disconnected the harness to kill the alarm and went home uneventfully.
Lippert has a handy troubleshooting guide, which I followed and confirmed that indeed, the motor was bad...as in frozen...as in, the manual nut used to manually retract would not budge. Guessing it was melted internally, I pulled it apart. That is actually quite simple: disconnect power, loosen the band clamp that holds the solenoid in place, remove the wire from the solenoid to motor (+) and slide the solenoid off, then remove two 4mm allen screws (top and bottom) and the motor comes out. Just be sure to catch the drive coupling.
On mine, unlike a lot of the 2006-07 Monaco folks (see writeups on that forum), my pump was clearly well sealed and dry. The coupling was clean and the factory blue grease clean. I could, however, smell burnt motor windings. I removed the manual retract nut (it is reverse threaded), removed the two long bolts, and tapping the case, pulled the motor apart.
Yep...fried. It appears one of the armature windings went bad and/or a bad brush or both. So...need a new motor.
Here's what anyone with one of these systems (ask the Monaco folks) will tell you...motors are NOT cheap. The RV dealerships want over a GRAND for just the motor. Lippert wants $977.38 (oh, with free shipping

), and even Amazon is $800+ depending on source. Needing the motor by Thursday, I ordered the Amazon one Tuesday night. And that is where it got interesting.
You see, if you call a parts department and ask for this 414850 motor that I pulled off

, they will not usually find it.
But if you give them the 179327 number, it will show up. That is what I ordered. What arrived? See pic #2.
Yep...it's labeled 414850, just a later serial number. I installed it in under an hour to include adding a 60amp C/B in a more convenient spot. And it works like a champ...arguably quieter.
SO...nope, not the end of the story. I know motors can be rebuilt; even Sailor Lou has a post on another site saying as much about this very motor. That led me to searching for a 414850 rebuilding source and what did I find? Western Motors Service Company in Rockford, IL. Turns out, they MAKE a W-414850 motor that is a replacement for the 414850...same .256in slot shaft, .8KW 12V motor as that 179327. One BIG difference...theirs is $385!

WOW...less than HALF the price of anywhere else that sells the official 179327.
Yep...half temped to order one from WMS and send it back as a return to Amazon...but my integrity is worth more than what I'd save.
HOPEFULLY...anyone needing to replace their motor will see this and save themselves a LOT of diesel money.
