There is a check valve on Ls for each user and one is open where the message from the lever is leaking out.

Boom float 244j locks with the joystick in position but the hydralics are not relaxing or floating


Putting the loader lever in the float position and having it raise the machine off the ground is a classic symptom of low pilot pressure. Setting the pilot pressure involves expensive gauges and a special procedure for setting pump output pressure, differential pressure, and standby pressure. I recommend taking your machine to a dealer to have them set.

Pilot pressure for each valve is 406-464 psi.
Minimum boom float engagement pressure is 334 psi.

How to change injector pump on CAT 428f backhoe?


Try to loosen the nuts on the fuel lines going to the injectors and crank the engine till all the air bubbles are removed from the system. Don't crank the engine for longer than 30 sec at a time letting the starter cool down before cranking again.

How to troubleshoot swing motor problems on a 1963 jd row cropper backhoe?


just like any hydraulic system there is A (IN) and a (OUT) on every cylinder and motor on tractor (even steering) loosten (NOT remove) the hose fitting thats on (A or In) to motor and attempt to move joint/device with controls if a steady drip of fluid is present then your problem is device (cylinder,motor) if no drip then follow hose up to power divider or solinoid or hand valve and attempt same procedure , keep moving up the line till you get a steady drip of fluid and last device in liine is the problem device , repair or replace it

ALLWAYS turn off motor and release pressure from hyd system before you attempt to completly remove any device from system for replacement , and note that booms and arms and heavy stuff will relax(fall) with no pressure in system , prepare for this to happen (blocking,chaining)

4x4 not working on a 2011 416 backhoe


You would think there would still be some warranty left on it, or at least some free tech help from Cat. Have you checked the rocker switch that moves it into four wheel drive - left side of dashboard. Sometimes these become faulty if used continuously. You can get help at this site below if you want to ask very knowledgeable people, and thank them for any assistance!
