Loss of multi function

[Parannor]

Hello I have a BX23S recently I seem to have lost the ability close my grapple and roll back at the same time. I know I had this ability before. I was behind on maintenance due to a layoff but today did hydro filter and fluid replacement. It did not fix the problem. Am I looking at bypass valve leak by?

*** I realized with that first reply TY btw that I need to add another detail. I haven't totally lost this ability it stops once the grapple is closed. So with nothing in the grapple I can grapple close and role back at the same time until the grapple fully closes then I lose the ability so I can't hold pressure with the grapple while rolling back to keep pressure on stuff I am picking up any more. ***

Do you have a true 3rd function up front?

Do you have a true 3rd function up front?

I have the factory 3rd function it is a bypass but it bypasses loader up.

I have the factory 3rd function it is a bypass but it bypasses loader up.

What your explaining is a diverter not a true third function???
How many hydraulic lines go in or out of the 3rd function valve?

I think we need more info on exactly what you are doing.

Sounds like you have the typical third function valve. While the grapple is closing it is passing pump flow down stream to rhe next function. When its fully closed and you hold the button down it.blocks flow from both downstream and upstream functions. When you release rhe button flow to and from those functions is restored.

How that effects simultaneous operatuon of bucket and boom depends on whether the third function was instslled upstream or downstream of the loader valve.

If installed upstream holdung button with grapple closed blocks all loader functions.

If instslled downstream and you are holding grapple shut:

You can dump and curl bucket all you want.

You can only raise and lower boom while bucket is moving.

Do tell us more about what combination isnt working
