D160 hydro pump

[dewdew 10]

I'm trying to take my hydro pump out. The shaft is broken so I don't need to move the motor yet. But there are 4 steel lines running into the bottom that look like they go into a manifold. How do I separate the two?

I can't answer your question but it may be in this tractor service manual.

Section 5 is for the transmission and I see they mention Section 4 (engine) for part of it.

 

Here is the transmission service manual if you don't have it.

I have an 18 Automatic parts tractor that I have partially disassembled so I took some pics to sort of show the area where you mentioned.  The four steel tubes are terminated into a rectangular block at both the hydro pump end and the hydro transaxle end.  These pictures are of the 4 tube manifold assembly connected to the underside of the hydro pump. Note two bolts are Allen socket head, and two are normal hex head.  If I remember correctly there are 4 "O" ring seals that are stacked on 4 square section type back-up rings (2 large & 2 small) for a total of 1 "O" ring and 1 square section type back-up ring per tube end.

This is very similar to a D-160 set up.

the manifold should have probably 4 bolts going into the pump, their will be 4 O-rings to seal the tubes,

If you have an FEL or Rear PTO remove them first...it will make life a lot easier.  Also buy a 5/16" extended allen socket (3/8" drive).  That will save a lot of 4 letter words.

 

There are 4 o rings that can be sourced locally.  There are however two rectangular Back up rings that I have not found locally but you can get from Toro

for the square cut backup rings measure them and know the size, try, Zatkoff.com they specialize in the hard to find seals and gaskets and are very customer oriented
