On a 2004 JCB 214E...
On a 2004 JCB 214E, is there a way to bypass the hydraulic pump for a manual lift of the bucket or retraction of the excavator? This machine has the Hydro-static transmission. Is it possible to isolate the excavator and bucket from the transmission so that it can be towed?

Is this machine down and you need to get it on a trailer? assuming the backhoe bucket is on the ground?

I have a full service book in PDF if you are interested I can also send you the Premium service offer as well as an additional service.

The hose burst protection valves (if fitted) prevent the loaderor backhoe falling in the event of a hose burst. These valvesmay be fitted on rams which raise or lower the loader arms,the boom or the dipper.

Checking Hose Burst Protection Valve

1

Raise the loader arms fully. Raise the boom to about45°. Raise the dipper to the horizontal.

2

Stop the engine.

3

Using the control levers, try to lower the loader, boom and dipper. Push the levers fully to the 'lower' position.If there is any movement, get the hydraulic system checked by your JCB distributor

Lowering a Load

During normal operation, the engine must be running beforea load can be lowered. The following paragraphs describehow to safely and correctly lower a load in the event ofengine failure or a hose burst; we recommend that only acompetent maintenance engineer perform the procedures.After lowering a load do not use the machine until themanual over-ride screw has been reset (Loader HBPV) or anew end cap and valve assembly fitted (Boom HBPV) by aqualified engineer, otherwise the valve will not operate asintended.

!

DANGER

Do not stand underneath the raised load during thelowering procedure. Stand clear and to one side until theload has been safely lowered. Make sure that the area isclear of other people before lowering the load. If you donot follow these precautions you or others could bekilled or seriously injured.

The burst protection valve if equipped need to be backed off to allow movement of your cylinders while using another machine to raise the backhoe into the towing position. Let me know

Hey Dan,
This unit appears to only have the valves on the outriggers. I pulled the battery and charged it. I was able to use the pump while cranking it to slightly lift the bucket and dipper. My thought here is that I can do this just enough to be able to get it on a trailer. The machine appears to have fuel delivery issues because I drained the fuel water filter and there is ALOT of trash in it. It would briefly start on starting fluid but that's not something I want to do a lot. I am going to have to trailer it off site to work that out.
