hydraulic Pump Overhaul Kit

Can anyone help me find a hydraulic pump overhaul kit? I have a 1948 IH 656 with a Thompson 7gpm hitch system pump that no longer works. I have searched online for several days and can not find anything. Any assistance would be most appreciated. Thanks!
 
First disassemble the pump to see if it"s worth
investing in a kit, or parts. Most hydraulic pumps
wear out from use, or abrasive particles in the
oil..which leads to the first question--how good
is your filtration? Do you have a 10 micron spin
on or cannister filter?, how often was it changed?
If you have an aluminum pump with bronze bushings
natural bushing wear will eventully allow the
gears to untercut the case and create a path for
oil to bypass the pumping gears, with a result of
loss of pressure. Cast Iron pumps, with roller
bearings cost more than aluminum pumps, but last
longer---SO, Inspect first, it would be less
expensive to simply replace the pump, than
invest in parts for a worn out pump.
I can give further detail if you advise the make
and model of the pump. I have worked in the
hydraulic industry for many years but never heard
of a "Thompson" pump, so I feel that they sourced
the pump from another manufacturer.
 
hi greycoat, can you advis me on a 130 international hydraulic unit. I put a new aluminum pump on it, put in new seals on both cylinders and the control arms put it back together and it is worse than it was before. did I miss something? thanks for your help, the Lord bless you
