[AT] Add-on hydraulics and power steering?

[John Wilkens]

Anyone know of a good book on very basic practical application of 
hydraulics and old tractors?  One specific is...can you use a front 
or rear mount hydraulic pump that is being used to run a loader (etc) 
to run an add-on power steering unit also?  What capacity pump would 
be required?  What kind of plumbing and fixtures would be 
needed?      Also, can a pump be too big to run such a system.    I 
tried to run a wood splitter off of a large BeeGee pump hooked up to 
the belt pulley shaft on an AC WC tractor (came off of a Cat) but 
about all it did was heat up the oil and stall the tractor.  One guy 
told me the pump was "just too big."  ???
