I was looking in a 1961 sales equipment book and they are listing the crawler as no hydralics,

single spool valve 15 gpm pump,

a fender mount 3 spool valve,

a 3 spool fender mount and fender hydraulic tank,

and then a 25 gpm pump with the 3 spool fender tank for the loader crawler.

OKay, My H3 has a single spool valve with the inside frame dozer assembly with tilt and angle blade that has bars where cylinders could be. I would like to find a tilt and angle cylinders for this machine and a 3 spool valve. I would also like to know what the collapsed and full length is of the tilt cylinder and the angle cylinders are. and I believe the 3 spool valve is open center. What pressure did this hydraulic system operate at?

Easiest solution would be to find the original parts... Does anyone have the valve and cylinders and lines for sale for the H3?

Thanks.
