Rate of lowering valve .

Post by simonwill69 » Fri Jul 09, 2010 4:02 pm

Hi,removed lowering rate cover,knob and shaft,and removed quad housing.
The needle valve is out of line(probebly why it was'ent working)with the housing hole and wont unscrew.It looks bent over to one side.Dont want to force it at this time,tryed turning it with the Knob and shaft,wary of snapping the little pin in the needle valve.
Options as i see them,
1.trying to bend the needle valve straight again and risk snapping it off in the valve chest
2 pliers to unscrew needle valve,see #1 !
(which ever,i will probebly need a new valve)
3 Bolt back,and leave alone

Ideas? Many thanks, Simon

Simon,

I'm pretty sure it doesn't screw in, it should "just" pull out. I'd be inclined to try a gentle twist and turn operation with some mole-grips.

Good luck

Alchad

ill tell you exactly what that is, someone in the past has changed the chest, had the washer for the screw in the wrong place and tried forcing the washer down past the hydraulic fitting to get t in, result: bent valve, seen it a few times, i reckon its probably wiser to get another screw, never worth risking it snapping off,

we use to have issues, we wanted earlier screw ones and they got harder to come by, although tapping a thread into a control chest seemed a bit risky

Thanks Jim and Alchad(noone more danderous than me!!),
So Jim,do i undo the 2 bolts (pressure line), as this is obscuring the base of the valve, which i assume is a retainer or sleeve.(its a 1200,case you forgotten)
Thanks

that washer sits in behind the hydraulic union, it prevents the screw from unscrewing out completely, people for get to get it in the right place then force it afterwards and end up with what you see, undo the 2 bolts and see if you can get her to one side but dont bend the pipes too much that they are a pig to get back, bare in mind there is 2 o- rings there so dont go to mad and knock them out, pop her out have a look, if its not cracked then try to straighten it if you feel brave
