Hydraulic Fan motors

Does anyone know of a 98-99-2000  U320 coach that is being parted out?  Would like to check on hydraulic fan motors.
Sauer Danfoss seems to be having problems in Italy.  Ordered pump and it was suppose to be here mid Dec. 2018.  I called the wholesaler Thursday  and she sent Italy an email so Friday when I called back , Italy had responded but answer was we are having quality problems and don't know when it will be built or shipped,  I have sent email to Bondioli & Pavesi in Virginia to see if they may have a pump that will spec. out to what I have.  SO in the meantime I thought I would check to see if anyone on the forum may know if there are any slightly used pumps available.
Thanks in advance

What exactly is wrong with your old pump? 

If the bore is bad it maybe plateable and diamond honeable back to size

Chis, is it the pump or the motor you are looking for?

I am missing something, it's a simple hydraulic motor,  mounting pattern and dimensions, shaft size, and displacement within 5% of specs. I would think a local hydraulic shop could match you up with a common motor or find new seals. Hydraulic motors are not typically rocket science.

The only thing you will have problem with is mounting holes location.  You will have to drill new mounting holes in the plate. I thought the motor info for a replacement was posted before but don't see the thread right now. If I run across it I will link it.

Here is a link to the replacement seal info that may help you out. Hyd Cooling Fan Motors

Cman resealed his recently and here is his info. hydraulic fan motor

Still can't seem to be able to find the complete motor replacement number that can be sourced locally.

Sorry I didn't give enough info-- I broke the threaded end off the motor shaft when taking it apart.  Motor works fine but can't hold fan on. I have talked to a couple of engineers and they advise against drilling and tapping for bolt.
The motor is a SHM2/22  Part no. M121.21.008.00 .  The problem is Sauer Danfoss is having some kind of trouble in Italy with manufacturing a new motor.  In original post I used pump and motor interchangeably  it is the fan motor that is broke.  I have put a seal kit in the other motor and it is ready to go.  Seal kit part no. is 221.20.034.OK same as what Beam Alarm posted on his re seal job.  The seal kit was about 120.00 but if it is only leaking around the shaft that is a metric seal that can be bought anywhere.  If I remember  right that seal No. is 30mm X 20 mm x 7 mm on eBay for about 7 bucks

different bolt pattern is no problem, I have mill and lathe can build new mounting bracket.

Engineers are going to generally be conservative in their recommendations.  I'd ask a machinist about it.  If you can drill and tap for the same size thread, mount it with Loctite red stud and bearing mount, hard to see what the problem would be.  Is the fan seating area on the shaft tapered?

I can drill it ( Carbide Drill ) but the tricky part is tapping without breaking tap in hole this is a hardened shaft.

My kids 45 years ago, when they tried to start my Bultaco with an impact gun. They broke off the end of the crankshaft that holds the flywheel. I drilled the crank and taped it. Put in a bolt and it is still working today. Post a picture if you can.

The center will not be that hardened as it is surface hardening.
