The Charge Pressure Sender is attached to the hydraulic filter head.

It looks like a one way flow restrictor. This would allow full flow in one direction and would limit flow in the other. As installed, it would limit flow when you retract that cylinder. Did that cylinder move faster on extend and slower on retract? If that is actually what it is, someone may...

This is the only reference I have read on BOSS Engine Temp Indicator. From: 753 Coolant temp sensor location? Post #4 BOSS Water Temp Gauge 1 Bar cold to 190degrees 2 Bar 190 to 198 3 Bar 198 to 204 4 Bar 204 to 210 5 Bar 210 to 217 6 Bar 217 to 224 7 Bar 224 to 231 8 Bar 230 on up warning...

Check for a shut-off valve in the heater hoses and also check if the orifice is still in the crossover tube. Pinch the hose in the middle of the "H". You should feel an area that you can't collapse. There is supposed to be an orifice in that hose. People have been known to remove that orifice...

In Minnesota if it is attached to the loader you must have the loader secured properly, and any articulating attachments (the backhoe arm) must be secured by a separate chain of suitable capacity to prevent movement while in transport. Extend the boom/stick enough to rest the bucket firmly on...

The mulcher motor may have a check valve preventing reverse rotation or there is a check valve somewhere on the attachment.

Three questions: 1. Do your auxiliary hydraulics work on other attachments? 2. Is the vibrator just a hydraulic motor that spins a weighted shaft? 3. Does it do the same thing if you reverse the hydraulic flow?

There is a simple procedure for testing cylinder piston seals. Disconnect the hose at the base end of the cylinder and cap the hose and the cylinder connection. Attempt to RETRACT the cylinder with the control valve. If the cylinder EXTENDS the piston seals are bypassing. Technical...

&nbsp If you are blowing that seal, then either: 1. You have excessive leakage that the case drain lines are unable to handle. 2. There is not excessive leakage, but a case drain line can not flow the volume due to a restriction or blockage. You could add a tee fitting at the case drain filter...

The valves on some backhoes require the oil to flow through the valve in a specified direction. If the flow is reversed the valve may not operate the cylinders or they may operate very slowly. Take the couplers off the hoses are swap them. Then connect them back to the loader and try it again...

&nbsp If you are making a "D" type retainer either: 1. Make the "D" large enough to be able to run a coupler through the "D" when there is already a hose through the "D". This is how large the factory ones are. 2. The better option is to make the "D" from two 90° pieces. The ends not welded to...

&nbsp You have a couple options. 1. Attachment Mounting Kit D-Ring part number 6729946. A flat plate of steel with a "D" shaped ring welded to it. This mounts to the left outside of the boom just forward of the tire. You route the attachment hydraulic hoses through the D-Ring and then to the...

So what caused the the no pressure issue?

If you have zero on the gauge, the charge pressure relief valve may be stuck open. On my 763, the Charge Pressure is supposed to be 200psi when the oil is 120° F. Does your gauge allow you to determine pressures from 0-300psi?
