HWH Slide – Hydraulic pump motor failure
Well gang I truly need your advice now.
Our 2000 Featherlite Vantare single salon slide has failed,
will not activate and advance in or out.After troubleshooting we discovered that the solenoid that
activates the hydraulic motor engages when there is a call for action. There
are 24 volts at the input side of the solenoid and when it is engaged it
delivers 24 volts to the motor. The motor does nothing, no hum or any other
sounds and does not start. From this I have concluded the motor has failed,
brushes or some other issue. So time to remove the pump motor and repair or
replace it.Has anyone ever actually removed a motor like this one? Must
the fluid be drained, hoses removed and the entire unit including the reservoir
be removed from the coach to remove the motor?Will fluid escape when the motor is removed from the housing
assuming there is a method to get it out without removing the entire system?After considerable time on the web it appears the assembly
is the HWH designated Monarch AP14012 – 24 volt – obsolete (http://www.hwhcorp.com/mr303354.pdf)link to the assembly drawing.The assembly is in the roof of the second bay drivers side
and inside an aluminum box. The box has a shoulder in the bottom where the assembly
is bolted and additionally glued in place. There is a ring where the 3” round motor
inserts into a square block. This block is the mounting block that is bolted to
the shoulder inside aluminum box. On the opposite side of the block the housing
is again round and there are at least four Philips head screws around the circumference.
There are no visible bolts or nuts on the outside of the assembly on the motor
side of the block that would secure the motor. There is a ring on the at the mounting
side at the motor that has treaded holes but nothing visible in them. Can
anyone provide some guidance on removing this motor, Please?My apology for the verbose post but need some advice and
thought more detail is better than none.Please any advice is helpful.
Thank you

Call HWH first (usually very helpful) and or Donnie Meyers…Ben Cummings. Geo.

Thanks

I assume that you checked that the the ground wire for the pump was making good contact. Some wiring arrangements will interrrup the ground when the “proper” conditions are not met, for instance the parking brake is not set.
Just a thought.

Thanks for the help.
Did get the motor out and benched checked it – DEAD
The brushes are worn almost down and one of the four had a weak spring. Called Monarch with the part number and discovered the motor may still be available in Fort Worth for 9650 – nxt step is to find a motor repair shop in Fort Worth or the mid-cities early next week.
Thanks again for the comments.

Raymond , I have used this shop , they do good work
a-1 electric motor service.
The shop is in a older part of town, and they have old motors stacked everywhere, but they do good work.

Thanks to to the recommendation from Jim Brown we have an
operating slide room.Quite an experience so I thought I would share it with you
and perhaps anyone who has a similar experience can find as easy a solution as
we did. The little motor 3” by 5 ¼” is difficult to find and is no longer
available from HWH. It is manufactured in Slovenia. When we discovered that if
available it would be priced neat $9650. When Jim advised he had been satisfied
with the service and work from a-1 electric motor service in Fort Worth we
wanted to seek them out for a possible solution. We do recommend this business,
don’t be swayed by the narrow path through the ruminants of previous repairs
and left over parts and bearings accumulated over the past 60 years or the
shear dismissal of any form or fragment of origination: fear not, Lupe knows every
part, where it is, and how it can be used when needed.Lupe wears two pair readers to see the details. He is the
nephew of one of the two founders in 1950 where they did repairs in the
basement of the house, which is long since gone leading the way for the metal
building erected sometime near 1970.When I called to discuss the motor and ask about the repair
the lady who answered said they did not rewind 24-volt dc motors, I told her it
may not need to be rewound. With that she said let me ask, then returned to the
call advising that she would put Lupe on the line, after describing the issue
he said bring it and I will look at it. Like the service we have all longed
from the 50’s era Lupe stopped what he was doing when we arrived and he
dismantled the motor and within 5 minutes he had discovered that an anomaly in
the ground had occurred. For some unclear reason the ground bushings had lost
contact through a bass plate that provided ground to the case. He drilled two
holes, inserted screws to secure the ground and voila it performed as designed
again.Total cost $270. The motor is back in the pump and
performing well.Thank you Jim Brown for the referral, very much appreciate.

Great report and even nicer was knowing there are still businesses that treat us as we would like to be treated.

Hey Ray,
Did you log Lupe’s contact information and physical address into the PC Map database. Others might be on the road looking to solve a similar problem. I had an generator alternator fail while in Maine at lunch with our dog in the coach. Fortunately we returned before the inside got too hot. We wound up going to a local, and I do mean local, rebuilding company. One man shop, lots of marine generators and alternators all over the place. Man took my alternator to the back, came to the counter and told me what the problem was and how long it would take to make the repair. I asked if it was possible to have it back by 9:00 AM the next morning. I got there early and the repair person asked what kept me so long getting there. That shop is logged on the PC map database.
We were treated to some down home Maine humor while there, at no additional cost except some sore muscles/flab from laughter. Shop is “the starter shop” at 101 Western Road, Warren Maine. The owner is Arthur Anderson, (207 273-2161. See how good my memory is …. I kept his business card and remembered where it was!

Thanks for the reminder, I will post the contact data.
