Is it possible to rebuild, or is there somebody who rebuilds the belt pulley high pressure/2 piston hydraulic pumps used on the VAC? I have a restored VAH and a VAC, not "restored" but really nicely maintained, in the family since new. The pump on the VAC works OK, but can be hard a little to "activate" if tractor has been sitting awhile, seems to get an airlock of some kind. I have 2 extra pumps, neither seems to work, even though its hard to see that anything is wrong with them, but I would like to get that one last thing working right. As an aside, the VAH single front wheel was apparently a common modification, presumably done by the dealer in the Pajaro Valley of California. I only know of one other one left, which is still used in active farming for towing irrigation pipe trailers.
