907 Backhoe attachment- slowing swing

[[email protected]]

whats the cheapest, easiest (least messy) way of slowing the swing on a 907 backhoe. this attachment seriously works great, its just so stressful trying to control the swing- it's ridiculous.

Have you tried limiting the engine speed when operating the hoe? It will decrease the hydraulic flow which will slow the movement speed in the hoe. You will still have the power, just with less speed.
If you want to maintain the speed of the stick and dipper and only want to slow the swing, add an orifice fitting between the swing valve and swing cylinder.
Drill out the orifice until you get a swing speed you like.
Alternatively, you could install a flow control valve in place of the orifice fitting. You can then adjust the valve to get a speed you like.
Costs will be around $10 for an orifice fitting and near $50 for a flow control valve.
I added a flow control valve to my 4 in 1 bucket. Without variable flow in my Aux circuit, the bucket was too hard to control with the engine throttled up.

yeah, i slow down the idle. the issue with that is every other function gets wayyyy too slow lol

For my old davis hoe a 3/32 orifice works about best , just took the line off the valve bank and put a 1/8 thick disk in with the 3/32 hole in it. The only downside is that if you use the full travel of the swing valve afterward it you will hear it labor trying to force oil through the orifice which will create heat. Just use less travel and it will be fine.

do i have to do one for each direction or will one work because its forcing the fluid back through it?

If you are using an orifice, you only need one. The fluid is restricted in both directions.
Some flow control valves only limit flow in one direction. You would need two of this type. The other option would be a needle valve which limits flow in both directions and is adjustable.

any reason i cant use an 1/8" fender washer (providing is the right outer diameter?) and drill it out as needed

There is no reason why not.

#10 stainless washer did the trick beautifully. at high idle it is about the speed the backhoe was before on low idle. soo relieved because it was damn near impossible to tame the damn thing. when the idle was low the bucket curl was so painfully slow.
