C160 - Hydro Pump repair

[Phan 14]

To everone,

I am planning to repair the hydro pump of my C160 H. It leaked over the winter when I waspushed snow. I bought the repair kit from Red Square. 

I never do it. Could anyone give me advice to avoid mistakes.

Thanks a lot.

I have rebuilt / overhauled a dozen or more of the Sundstrand power units.  The C-160 s/b model 90-1140, if original.  

There is NOTHING DIFFICULT about doing this...if you know what a wrench is...you can do it.  I've prepared and posted a .pdf file for your guidance.  Here it is.... 

NOTE--- it is pointless to rebuild just the Hyd PUMP--- you must also rebuild the Hyd MOTOR.  I say that because they share the same contaminated fluid and microscopic debris in that fluid damages similar soft brass parts in the Hyd MOTOR.

Hi Thank - I am sorry for my late reply.

The document is useful. The time, I need do a repair on the pump first.

Then, I will consider to work on Motor as you shown in the document.

 

For the pump - I would the instruction how to do repair it. I you could guide me is appreciated.

My .pdf file on the pump overhaul can't be more descriptive.  What, exactly, are you asking me ???

@Phan What you have pictured is the implement lift hydraulic valve and it’s hose connection to the implement lift hydraulic cylinder. 
The pump is mounted on top of the transmission and so is the hydro motor.
