MF 175 / MF FE 35 X Hydraulic Pump

My Brother in-law has decided to REPLACE the INTENAL 3 POINT HYD. Pump on his MF 175,four cylinder Perkins Diesel. His MF 175 has Multi-power, and possibly a PTO system that does NOT utilize the Dual Clutch arrangement like my MF FE 35 X.

I Located and purchased (for my Brother in-law) an ORIGIAL MF 175 Operator Manual, an ORIGINAL MF 175 SERVICE Manual as well as an ORIGINAL MF 175 Parts Book from a supplier in the USA.

Today I ran my MF FE 35 X on a PTO Slasher with a NEW INTERNAL HYDRAULIC PUMP and all ran perfectly!

My Brother in-law would like to install a KIT in my MF FE 35 X Hydraulic pump (old / used Pump) and then install said Pump in his MF 175.

Could someone please verify if the 1963 MF FE 35 X INTERNAL HYD.OIL pump will in fact fit into and work properly in a MF 175?

There are obviously several different brackets that would have to be transferred from the MF 175 pump onto the MF FE 35 Pump:

Thank you for any assistance:

I don't think it will fit, the auxiliary pump support bracket the 175 uses I don't recall that it will fit the 35 pump. 175 with the auxiliary pump needs to be split at the trans-diff joint for pump replacement too, it won't come out the top like the 35 does. Believe the 175 three point is larger on GPM flow also.
 
Well, these pumps comes in Mark I, Mark II, and Mark III versions.

Mark III pump is the latest, and they started using it a bit up in the 70ties. It has a lot more splines on the axle shaft than the two others, and it has a hanging filter, and under the centerhousing there is a cover for replacing that.

But, the Mark I and Mark II pumps can be interchanged. The Mark II pump has as far as I know always a filter, and it is a standing filter like on your pump. The Mark I pump can either be without the filter, that is valid for the oldest pumps, while a bit newer Mark I pumps had a filter, just like the one in the picture.

The Mark II pump has bigger pistons, so it pumps a little more oil, that is more or less the only difference.

Both pumps were used with Multipower pumps, and honestly, I think the brackets are the same.

Why does he want to use your pump instead of his own pump ? Is his faulty too ? Why not buy a pump kit for his pump instead of your pump. Unless he has a very new MF 175 I assume he has a Mark II pump, while it is a Mark I pump in the 35. The only thing he will notice is that your pump will make the 3 point linkage to lift a little slower. Not a whole lot, but some. I think the Mark I pump gives something in the neighborhood of 12-13 liter per minute, while the Mark II pump gives about 15-16 liter per minute. Same pressure.

When the pump in my MF 65 from 1960 was worn out, we bought a Mark II pump for it. We got a pump with filter, the old Mark I pump did not have a filter, and a little faster hydraulics. Other than that everything worked fine.

Hope this helps some.

Looks like a PUMP swap is not going to happen:

Forgot to say, if the MF 175 has the little cover on the left side under the centerhousing, then the tractor has a Mark III pump. If it does not have the cover there, it is a Mark II tractor, and the pumps will interchange. It is supposed to be a little in front of the cover with the PTO lever. But on the underside, so you have to get down under the tractor to see it.

 
I've never bought a pump, always just bought the new valve blocks and pistons and repaired pumps that way. That's how the dealer I worked for years ago did them too.
