We have a 2005 36’ Beaver Monterey Ventura IV with a Cat C9, with 27K miles on it. On our last return trip home, I noticed the Allison Tx was running noticeably hotter than for the last 9 years, up in the 188+ instead of the nominal 165 degree range. Once home, I discovered that the hydraulic fan pump/motor bolted to the passenger side of the Allison is drip/leak at what appears to the bolted joint between the 2 major subassemblies of the pump/motor.
Looking for recommendations as to who/what company I might contact to purchase a Sauer/Danfoss hydraulic fan pump/motor replacement gasket? The model/type of the Sauer-Danfoss pump is CPC-1018 (see attached photo), built sometime in 07/04.
I have already contacted:
- BCS Parts: they do not carry anything that specific for the chassis parts, nor had a recommendation of what company to try to start calling
- JDRV up in Bend/LaPine, OR since their website specifically mentions replacement Sauer-Danfoss fan motors and pumps, and they can even get custom replacement pump made up. Figured if they had the pumps & motors, they must have access to replacement gaskets. Net: bad assumption: JDRV can only get the pumps, not the gaskets.
- Called NW RV Supply since they also carry Sauer-Damfoss fan motors on their website, but they also do not carry the gaskets, not if you buy a new pump, a new gasket does not come with it either
- Called Henderson’s in Grants Pass, not for the repair, but for a possible lead. Henderson’s said a real long shot on something like that might be Pacific Truck Centers over in Medford, OR (authorized Cat, Allison, Freightliner, etc shop). Called PTC: Net: they can only look up Freightliner chassis items.
- Called the Danfoss company itself, and they referred me to the nearest Danfoss Authorized Dealer; Berendsen Fluid Power, in Eugene, OR. The service rep there did spend a lot of time researching this for me and he said that Sauer was bought out by Danfoss, but then that specific product line was again sold off to some other company who he did not know of. Net: Danfoss itself did not have a replacement gasket.
- Sent off e-mail to hydpumps on eBay since thsy seem to carry Sauer-Danfoss-Sunstrund gasket repair kits, thou no kits were listed for the CPC-1018 or its family. Waiting for a response back.
- I’ve dropped a PM to Lee Welbanks (author of original post) last week, but he must be offline and has not had a chance to respond back as to where he sourced a replacement gasket, or if he ended up having to cut/make his own out of flat gasket material. Lee's original pictures (below) sure looked like factory cut gaskets to me.
Has anyone else attempted/completed this type of Danfoss pump/motor repair, and if so, do you remember where you were able to find the correct gasket? I'm planning to complete the repair myself if possible.
If not, any recommendations of who/where next to try to contact to either secure a gasket or to have the unit repaired (I am still assuming that leak is indeed just the gasket and not a larger issue such as a cracked housing, bearing/shaft issue, etc)? Is a general consensus that I just start calling other heavy truck repair centers, like PTC, or construction heavy equipment repair for hydraulics, or others?
If I do have to drive the coach for the diag & repair, our preference would be somewhere around the south-west Oregon area, say Medford. But if needed, I would start calling places up I-5 north, up to Colburg/Junction City area or beyond, or even over to Bend (6+ hrs, 1-way). Distance to repair does matter since I loose about a quart of TranSyn every 30-40 miles or so.
Thanks
