4300 bucket curl 'dead spot'

[bud4410]

i would say it is probably the regen circuit. when i put on my front blade i would get the same dead spot when i would angle the blade. changed the regen lever and the problem was cured..........bud

i will try that 1st before i go changing hoses around. i actually can't remember if i have it in regen mode or not, have to check the book to see what the symbols mean...can never remember.

That is becasue the blade has two SA (single acting) cylinders, when in "regen" both lines are pressurized causing the blade to "stall".

of course i read it...just didn't understand why under some weight, it works fine but over a certain weight, it does not. also wasn't sure how part #43 had anything to do w/ 'load check'...i didn't want to bother you with stupid questions until i tried some other simple things 1st.

Part number 46... Sorry about that.

ok, that's what i thought you must have meant, but wasn't sure. is it possible for this check valve to work fine w/ 200lbs on the frame but get 'forced through' w/ 300+ lbs?

not sure i am asking that right, hope it makes sense.

Yes-it make perfect sense, and yes-it's very possible, more weight=more pressure it need to hold.
