Massey Ferguson 230 front mount hydraulics Pump Specs

Hello,
Everyone I'm finally geting back to my front mount hydraulic pump project and would like to know the pump specs. SSB tractor sold me a pump with specs that are GPM 15.84 @3000 RPM, PSI 2900 With a CW rotation.My question is will this pump provide me with a sufficent hydrualic pressure to run the loader and is the CW rotation correct ? PS I will never do business with SSB tractor ,because , they sent me the wrong drive shaft and this pump I could have purchased from Northern Hydraulics 100.00$ less. I had to actually dispute a charge with my credit card to get refund for the drive shaft. The tractor I'm working on is a Massey Ferguson 230 gas Z145 continatial motor. Nathan

I did a mock up of it on the garage floor and it look like it will work the drive shaft with the left handed thread will turn in the direction to tighten down . Nathan
 
15.84 @ 3000 RPM seems a little small. The stock pumps when combined are around 12 GPM @ 2000 RPM. I'm looking to by a pump from
the surplus center in Nebraska (surpluscenter.com). A Prince or Cessna pump of around 2.32 Cu In displacement seems about right. A little
over 19 GPM @ 2000 RPM. $354.00 for the Prince and $460 for the Cessna. I may even consider a 3.0 Cu In pump but that may be a bit
much.

15gpm is plenty good for running a FEL, if you had a TLB you need at least 20gpm. The internal pump for the MF230 3point lift is only 4.5gpm which would make the loader painfully slow. When looking at what direction a hydraulic pump runs you always do it by looking at the pump where the input shaft facing towards you. It should be a CCW pump, some pumps are made so you can change the direction from CW to CCW, or CW to CCW depending on how it was put together. Some people will look at the pump rotation with the input shaft facing away from them which is wrong.
 
Yes 15.84 GPM is good for a FEL but that is achieved at 3000 RPM. The governed speed of the 230's engine is around 2100 RPM so you are taking away 30% which equals 11.1 GPM. Normally one does not run a loader tractor at full governed speed when doing light to medium work so if you're running say 1500 RPM now you're down 50% to around 8 GPM. All of this my be fine depending on the loader cylinder size and how fast one expects the loader to operate. Below is a handy calculator to figure out the linear speed of a cylinder. Of course for a FEL you would need to divide the calculated speed by two since there are two cylinders.

After doing another mock up on the gararge floor you are correct the hydraulic pump needs to turn ccw. The dynamic gear pump can be easily changed from CW to CCW.The dynamic pump is at 15.84gpm@3000 RPM will be twice as fast as the internal tractor pump at 4gpm @3000 and the PSI is the same for both pumps so it should be a nice upgrade and I no longer have to switch back in forth from 3-point to front end loader by diverter valve.

Inaddition, I will be using a morflex coupling to connect the drive shaft to the hyrdraulic pump and the drive shaft is made from .750 Diamter key stock.My questions are is the morflex coupler a good way to connect the drive shaft to the pump and is the .750 diameter drive shaft heavy enough material to drive the pump without any flexing of drive shaft ?
