Here's Fumotec's PDF of his track hoe, scroll down to pg17 for the hyd system installation. It's the same system that Premacon assembles to sell as a kit.

Your pressure line on one side of the valve & the pressure relief valve on the direct opposite side. The other two ports should be plumbed back to the oil tank with inline filters. The one returning oil line will be Y'd to the prv.

Fumotec uses fuel tanks from helicopters (he is afterall an employee of Vario Helicopters) for oil reservoirs. Your dozer wouldn't need a tank capacity of any more than 250ml or so.

That Jung pump is capable of putting out 100bar (1400psi), so when you deadend the cyl stroke & the oil has no where else to go, the pressure line will explode in an instant! I hope you're wearing eye protection when you're messing this stuff?!
