bucket tilt

[gleneben]

i have been having issues with bucket tilt , i found out that both tilt cylinder rods are bent. replaced both cylinders and when you pull or push the lever the line to the will pressurize but the bucket wont move. i swapped the lines from the lift cylinders and the bucket works fine and the lift has no response. i want to replace the control but they all have an in and an out port but havent found them with the PB port?

There is a PB sleeve that is added into the valve port (Tank return or neutral)

It sounds like you have one set of lines to the new bucket cylinders reversed so that they are working against each other.
Consider posting some photos of the FEL cyinders and plumbing.

Your control valve is not the problem. You have a problem with the hydraulic connections.

is that common for most after market valve bodies ?

Yes but your problem is not the valve.

i will post pics soon as i can , thanks for the info.

You need to do some simple testing to find the source of the problem.

If the cylinders were opposed they would not work when switched to the boom spool. I think we can rule that out.

I don’t think any hoses are crossed up , when I took the valve apart there is a Square piece of metal with a 1/8” hole in the middle of it at the bottom of port D Is that supposed to be there or is this a replacement for a different model. I know my dad was at least the fourth owner from the receipts that came it

Pictures are not going to fix this. You need to test the circuit to see what is happening. Boom works so you have pressure. Whats happening at the bucket ports on the valve? Thats easy to test.

My bet is that your supply line from the adapter block to the inlet port on the valve and the line from the PB port to the adapter block are reversed. On a PB type valve block this can cause your complaint.

Which affects the tank spool but not the boom spool. Good call and easy to check. I note there has been no mention of changing sny of those hoses.

Yes flow will through the the tilt/bucket spool and operate the lift/boom circuit but backwards. If the tilt/bucket spool is shifted it will block flow completely and open a main relief if this has one. If it does not have one, well then I would say it is a game of Russian roulette.

Russian roulette with 5 bullets in the cylinder.

I played that game by mistake once in 1984. After dropping 20 gals of hyd. oil on the floor I have trained myself to make sure my circuit is complete or has a method of managing that flow LOL.
