I'm looking for someone that knows hydraulic controls. I bought a towable back-hoe. It has 4 control handles/levers. Left to Right Boom Swing Boom Up-Down Arm In-Out Bucket roll In-Out Is there something that can be added to slow the swing? Also when I push the boom up it drops some before it goes up. Is this a defect or is there a simple adjustment to fix this. Thanks, Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

| Dusty, check out "color flow valve". But they're pricey. In any case, you need a restriction in the line, adjustable is nice. There are fixed-orifice flow restrictors available too. You'd have to experiment to see what size you need. But it's basically just a coupling that screws in between your hose and the cylinder. |

Surpluscenter.com has adjustable flow restrictors, about $10. You might need 2, if your machine uses a ram(s) instead of a clock motor, to rotate the arm. What machine are you working on?

| There are several different styles available, and obviously different sizes, fittings, flow rates etc. Look on ebay or surpluscenter or Baum hydraulics or your local place for a "hydraulic flow control valve" I personally like the kind with a lever to one side better than the needle valve type, but that varies by application. |

| if you bought it used your control levers and boxes might have alot of wear, do your levers wiggle without the hyd's moving anything? sometimes it's just a pin on the bottom of the levers that gets wore. not saying you don't need a restrictor, but i'll bet your controls are wore alot. also try to work them with the engine slowed up a bit, you ussually don't have to run the engine full throttle unless you are constantly moving the arm. |
