Hydraulic Fan Motor

[Bob Baldwin]

My 1992 Beaver Baronet Hydraulic Fan  Motor is leaking. I called Gillig they told me it's been discontinued. He gave me a number that should work # 163K1027 no luck finding it. I can find a 1028 or 1029 but not the 1027.
Other numbers found on the old fan motor  53-24464-1 there is a Gillig number 53-24464-001 but Gillig said that's not it. Other numbers on fan motor 444968-40 L91P.
Any help with this would be appreciated.

Have same problem with my 96 Pat.  Check with Matt at BCS Parts, he may have someone that can rebuild it.

Most mid 90's coaches used Sauer-Danfoss fan motor.  Not sure what model was used on the 92.  They are usually rebuildable by a good hydraulic repair shop.

There is a good thread here http://beaveramb.org/forum/index.php/topic,495.0.html

I got back with Gillig about the fan motor. He gave me information on the place they last got one. Turns out right here in my home state. Hydraulic & Pneumatic Sales, Inc.  Charlotte, NC. Got with them today and was told. Price on a model 163K1027 will be $406.69 each, with an estimated lead time of 16 weeks after receipt of an order.
Looking in to a rebuild now. to long of a wait.

Looks like a Sauer-Danfoss TAM22-90  There will be some more numbers on it that will be needed if you want to try and get a replacement.  There is an issue with using the old switch valve on the replacement hydraulic motor.   See Richard Ames work around. 

[William Ervin]

After a lot of net searching I found a local service center in Grand Praire TX, about 15 mile from the house.   I'll have to check it out when I get home.

Steven just in case I need to replace rather than repair,   Where is the work around?

If you look at the thread from Richard Ames and Gary Engen you can see from Gary's pictures the difference in the replacement motor and the old motor.  The old thermal switch valve has 3 attaching bolts the new motor only has 2 bolt holes.

Richard had an adapter plate machined to go between the new motor and the old thermal switch valve.  From what I gather a new thermal switch valve is a 3 month wait from UK.

Bill,
From what I understand, the Sauer-Danfoss hydraulic motor division was sold to a British company with a manufacturing facilities in Italy that makes the motors now. The problem is that they will not make a production run for a specific motor until there are enough orders to justify the cost. Therefore, there is normally a 1 to 6 month wait when ordering a new motor that is not in current production or considered obsolete.

Thanks Gerald

I talked to Matt at BCS a couple of weeks ago, and had planned on going up to Bend last week.  Plans had to change and I didn't make it.   I'm going to call Matt this week and see if he came up with anything.   I also checked here in the Dallas area, I found a service center for Sauer-Danfoss in the Arlington/Irving area about about 20 miles north of me so we'll see where that goes??

Chances are, fixing the drive will be as much as replacing it, but we'd get it back before next spring!!

Timely post, I'm in the process of pulling my hydraulic fan motor now.

Hi Bill...I have a 1990 Beaver Marquis and also needed a hydraulic fan motor.  Don't know if the fan motor would be the same as yours.  We tried to do a rebuild kit and it didn't work for very long so we went with a new motor.  Don't know if the following information will be of any value to you, but might be if your fan motor's original number was/is the same as mine, we'll see.
My Gillig number was 53-24464-001 and since they don't have them any more; my new number, from an eastern company,  is Webster # WE44968-29.  The fan was shipped out of North Carolina.  I was not privy  to the company' name it came from.  Hope this helps.

Here is a Pic of the bottom with all the numbers stamped into it.  Its a large file so you'll have to slide it to read all the numbers

Matt at BCS is still trying to get hold of his guy that rebuilds them, I talked to a parts guy at hydroquip here in Dallas and he's checking with the company in UK to see if there are any retrofit seal parts or work around ideas.

[Wayne Tull]

Here is a picture of the Hydraulic fan motor from 93 build RV.  It has a keyed shaft.  My shop thinks they might be able to rebuild it if they can get the seals. The internal seal was shot.   

5/26 Update- Unable to find seals for this motor, so with $590 + shipping from Gillig (note they only have one of these left, it's a discontinued item) and some new fittings to adapt it to current setup it should be a go. Oh, + labor of course.

With that number you should be able to get what you need.  I called Danfoss directly a few years back.  They bounced me around a few times till I got someone who could help.  I gave them the numbers on my pump and they gave me the replacement pump number. 

Some of those numbers I know what they mean. The last few I don't have notes on.

TAM 22-90 Bidirectional gear motor Group 3
26.5 = 26.2 cc/rev displacement
Maximum pressure (bar) continuous 210
Maximum pressure (bar) Peak 230

cl 07 is the spec for the Shaft /  Front Flange Combinations.
It specs out the location of the mounting holes, shaft size etc.
