Title: HWH PUMP/MOTOR/TANK AP 29281
Post by: Laurence Mitchell on July 16, 2021, 09:53:25 PM
Hello fellow beavers!

When it rains it pours at times!  Our 2007 Beaver Marquis had slide issues on our last trip.  2 out of 3 slides came in and the last one had to be "jumped" at the solenoid to have it brought in.  We got our coach home and our tech has discovered that the solenoid is bad and needs to be replaced but cannot find a source. (He has a company that can rebuild it here in Tucson and he has reached out to  Beaver Motor Coach /sales, they are looking but I'm hoping someone in our club has been able to find this part.  It's a HWH pump/motor/tank AP29281 with 6 solenoids. 3 for slides and 3 for levelers.  Thanks in advance for any help.

Mitch.

The HWH website seems to indicate that part ap29281 is obsolete and is a pump or pump motor.  I would suggest calling HWH and getting their opinion.

I think the RAP part number means it's a "replacement" part for the listed AP part number.  Aren't the solenoids a different part than the pump/pump motor?  That would mean the solenoid is a different part number - yes?

I would think a call to HWH (before they close on a Friday!) would provide a part no. and local source.  Not sure what your tech means by “rebuild”.  The solenoid just fits to the manifold on the tank.  Some have rebuilt solenoids, but then I’d think O rings wouldn’t be hard to come by.

Another source for HWH is: Stuart's Service 800 826 6267 I used them many times for parts. They usually have what you need. And you can speak with a real person that knows what they are talking about.

A few months ago I ordered a replacement slide soleniod from Northwest RV Supply (541-746-9092). It was listed as RAP90729 but I believe the current # is RAP42632. $184.46 plus shipping. The solenoids can also found on ebay.

HWH will rebuild your solenoids.

Curious why you would have an odd number of slide solenoids, you should have two per hydraulic slide, one extend and one retract.

It's Saturday and I will be calling 1st thing on Monday morning to Stuarts Service, HWH and NW RV supply.  I will continue to research today and tomorrow.  My tech informed me the part number he was given was RAP42632 but I will verify with HWH on Monday.  As for the odd number, I have 3 slides but cannot tell you more that that.  ;P

I do know I will be purchasing 2 of the solenoids to have one as a spare.
