5" petrol chipper hydraulic oil pressure

[PC tree]

Anyone know why the hydraulic oil is pressurising in my greenmech chipper? It's leaking out around the filler?

 

Cheers

Are they GM men?

Does the filler also contain the filter? If it does and this is blocked then that's a likely explanation which wants sorting pronto, and the reasons as to why it has blocked investigating thoroughly.

If the oil is 'pressurising' the hydraulics are probably sucking in air from somewhere - check all connections between the tank and hydraulic pump (there may be an inline suction filter that isn't sealed correctly, allowing air into the pump).

Can you be s bit more specific?

 

A hydraulic system is supposed to pressurise

 

Is the leakage fluid or is it bubbles and froth

Lol, thanks Pete, didn't have the opportunity to ring them today...

It seems to be leaking from the area around the dipstick, when I pull that out it releases pressure. This is not the pressurised side because it's the tank. Though the pump is on the same housing.

the suction side of the pump could be drawing air or have a restriction on the suction screen which is making it draw air hence the hyd tank pressurises and blows oil out of the easiest orifice or around the return filter some machines do pressurise to stop cavitation but i would think that your chipper isn't built so . check jubilee clips on the feed to the pump or look for pinholes etc
