E215 fk 2003

[pcarvillmiddletown]

Any help greatly appreciated. So I have a e215 I bought with very slow hydraulic movement on every control also the throttle doesn’t work and won’t turn of on key ive got the ecu checked out with nothing obvious wrong has anyone ever had this problem is there a wiring problem on engine loom of relay or some that controls the power goin to engine loom thanks in advance

You can do some checks on the monitor but it sounds like the mechatro controller (ecu) is not functioning in the machine. Is your monitor display working and do you have any faults being displayed on the monitor?

Kind regards

Yes but I got the ecu looked at and it’s ok yea the a fault on screen and can’t clear it or I’m not sure how to I’ll look tomorrow again see wat it says but some like cam or cun think its a ecu fault code but its not putting the correct power to the hydraulic pump or the stop start or acceleration diel is there one wire that runs from euc could possibly be broken and cause it maybe a earth problem?

If the main controller has lost its power supply or ground connection or if the controller has a internal issue then the display will show "CPU MECHATRO FAIL" , this means the monitor has lost its communication with the controller. No working controller then no machine operation. You may have a KPSS and swing brake release switches behind the seat under the rear speaker panel. These should give you emergency operation function of the machine when switched.

Kind regards

Yes I think I’ve a bad connection or broken wire problem have to see this happen before would that be the problem for all the pump slow the stop start and the acceleration the ecu is perfect so what’s left wiring ? Can the pumps be manually activated to return to full pressure?

 

[Kobe Steel]

Only switch available to bring the pump online is the KPSS switch behind the seat. That will give a fixed power supply to the pumps solenoids for partial operation. When the controller has no power this will cause issues with the pump control and the engine step motor control. hopefully you may find the issue within the wiring or power supply circuit which will save you from buying a new or used controller and then only to find the machine is still not working.

Ok I took ecu out and sent it to a man to look at he opened it and found nothing obviously wrong but there could still be a problem with it when the ecu is plugged out the digger still operates the same as when it was in is that any indicator of a problem do you know where I would get a ecu if needed

 

[Kobe Steel]

Its possible that the controller is at fault but if that is the case then it is very important to check the power supply and its connections to the controller and the wiring to and from the step motor. If the controller has sustained any damage internally then you don't want that occurring again with the new controller. Sometimes the controller just gives up and dies for no reason. Have a read through this post where the controller was giving issues on a Kobelco.

If you can get your hands on another controller from a wrecked machine you would be on a win otherwise this trading company may be worth looking into

Is it possible to put constant power to the hydraulic pumps to give them full pressure and put hand throttle on the engine and stopper cable ?

 

[Kobe Steel]

Yes you can but you must limit the solenoids current draw on the pump to 750 milliamps. you would just need a way of switching them off when the machine is at idle so they are not drawing high current when not in use.
You could put a throttle cable on the governor as well. You would just need to make and modify some brackets to do the job.

 

[pcarvillmiddletown]

There’s 3 wires goin into them there on the right hand side of pump what colour is the feed and how would I reduce the current would a 6 volt battery wired to them work ?

My friend.
The New Holland E215 excavator is equivalent to the Kobelco SK210-6E.
So it doesn't have a KPSS switch instead, it has a backup cable to control the engine speed and it also has 02 backup screws right on the regulator of the main pump.

Cheers for that I’ll check that out in the morning will when screwed out the pump works at full capacity there was somebody working trying to screw pump pressure up before thinking this was the problem do u know the original pump settings

 

[pcarvillmiddletown]

Ok I’ve bypassed the pump now there’s power on hydraulics but it keeps dead ending on the tracks and on dipper in and boom up what is the pump adjustment does it have to be moved from original when electrical is bypassed thanks

you could try backing off the regulator adjustments on the pump , just remember to take a reference so you can set them back to the original positions if you need too.

 

[pcarvillmiddletown]

Ok so I’ve by passed the electrical end of the pump by screwing out the lock nuts yes she has power but killing the engine putting serious pressure on it when I boom in or crown the bucket it doesn’t do it but when I lift the boom is stalled the engine when I track it does the same i adjusted the regulator screw both ways to no avail would the sqush plates be done in the putting pulling full load on it ? Or does anyone lnow the correct setting for the regulator? Plz I’m beginning to lost it with the one

 

[Kobe Steel]

The adjustment you can try is located on each pump regulator so both pump regulators will need to be adjusted by the same amount of turns. You need to loosen the large locknut as shown in the pic and adjust the screw counter clockwise, adjust 1/4 turn CCW on both pumps each time and then try the machine operation. remember to write down the reference of where the adjustment was set too. The screw has a machined shoulder so it can not be screwed out of the housing so it will only adjust out so far then it will stop once their is no more adjustment left. As these types of regulators are controlled by solenoid operation their springs are very heavy in comparison to units that don't have solenoid flow control. Unfortunately this mean there is a limit to how far you can reduce the pumps horsepower setting without changing the regulators spring set.

Kind regards
