Leyland 272 Q cab

[M.davis33]

Looking for advice on a 272, can’t get any good of the rear lift arms, have had the rear end apart and nothing obvious at fault, wondering is there anyway of diagnosing if the pump is at fault, you can hear it trying to pump.

 

[diggerjones]

Obviously you have messed with that large knob type thing at the back on top. Will it tip a trailer.

 

[M.davis33]

How’s things, all that does is lock the lift arms in place, they’re sitting down at the moment and unable to get them back up.

Play about with round thing that locks arms out put pry bar behind it and play about with it

Is the pto hand clutch locked back, as this stops pump drive,
So is the pto working as it should, ,
Other thing is there is a bolted coupling in backend, think there is 6 bolts in it, if they shear, no pto or hydraulics, again check pto is working,

 

[M.davis33]

If we manually lift the arms and lock them into place we can then unlock it so this isn’t the issue that round thing is working perfect,

Yeah pto is working perfect no issues what so ever working off the handle as it should

Sorry can't help

Is the spool valve/tipping pipe working?

 

[M.davis33]

No, was working but stopped

 

[agrimax]

You're aware that the gearbox and rear end have seperate oils? Rear end has a level bung....is there plenty in it?

 

[M.davis33]

Yeah you take the bung out of the side to check it, plenty oil a good 10-12 gallons in it

 

[leone75]

Is there 2 extra spool valves on it if so the oil goes from the pump to them first and the relief valve is in it there are 2 flexible pipes from the rear end to the valve block if fitted the wrong way around .
If fitted the wrong way the pump cracks on first pull of the levers

 

[M.davis33]

Thanks for the response, no she’s got only one spool valve on the back so that’s not the issue.
