Green mech ec150 lister engine

[jake93]

I've got a green mech ec150 chipper it's had a new sensor fitted and the red light goes out out when engines up to speed but no stress still won't turn they try to move when I knock the anti stress bar and the back but don't continuously turn only one wat then the other please help also will attach a video of what it is doing

What happens when you override the No-Stress by turning the tap by the No-stress solenoid valve through 90 degrees  ?

Do the feedrollers then operate in forwards and reverse on the red bar ?

[jake93]

Yea but not continuously but does it with the tap closed and open see the video I attached it does it 😞

Sounds like probably oil level or pump flow.

Guessing they're belt driven, that would be my first thing is to check belt tension after oil level.

[Jase hutch]

The pump is driven via a coupling off the end of the flywheel shaft.

Does the coupling look complete ? Is there enough hydraulic oil in the tank ? Is the hydraulic oil clean or does it look contaminated ? I would check the fittings are tight on the pump in case it's sucking in air ?

[jake93]

Yea the oil does level looks fine had a look at it, possibly about fit for a change but the gasket on the filler neck leaks a lil bit would that cause the issue I was possibly thinking solenoid valve ? I've tried turning the tap in and right out on valve and the tap 90 degrees but nothing I do seems to work 

[Jase hutch]

If turning the tap through 90 degrees makes no difference then I doubt it's the solenoid valve at fault.

Take off the pressure hose from the pump at the feedroller control valve and put this into a bucket  , run the engine and check the flow of oil into the bucket  ? It should be a good continuous flow , free of air ?

The pressure hose is the smaller of the two hoses at the pump.

Mistake

[jake93]

The smaller pipe that goes into the middle of the motor? 

[GarethM]

Jase is saying feed pipe from the pump on the engine to the valve block, so you'll know if the pump on the engine is knackered, have two people tho.

 

One to turn it on/off and one to make sure it doesn't whip out the bucket.

Any update on this ?
