Power Steering Handpump Rebuild
 

The steering box on this 1772 was pushing oil out of the top near the wheel so says the previous owner so I figured it needed rebuilt(re-gasketed).

I pulled the engine and drive shaft, this one is getting the "MacDrive Shaft" conversion, thanks Sam.

I pulled the rear cover last week and drained all the Hytran and crap out of it so the rear is dry at this time so I layed her on her side to ease the removal of the column.

Got the steering column out and put it in the vice to bust it apart.

I took lots of pics to make sure it all goes back together like it came apart. Here is what they look like inside. This is the first plate removed.

2nd plate....watch out, those springs will shoot out.
Attachment 89004

This is the valve plate.
Attachment 89005

This is called the valve ring. It is matched to the plate.

More springs.:NailBite:

Some plates are held together and are not to come apart like this one.
Attachment 89008

This is called the metering package. It will not be torn apart here because it works fine. This is covered in the book and it will need to be shimmed when reinstalled if it is disassembled. The brown ring near the center is the commutator seal and it will be replaced with a new one that is in the kit.

Next is the thrust bearing spacer and bearing.

Here is the other seal and spacer that gets replaced.

All that is left is the retaining ring, plate and washer. Once that is removed the shaft will come out of the tube.
