Yes I do know pressure is a product of flow but the hpop is a variable displacement pump so you could have 4000psi with ,say 2 l/m flow or 1 l/m and 2000 psi . _________________ 2 New Troopers ! |

Yep going with the swapping idea
but like the pressure test idea too no good at brazing ok with a stick welder and 4 mm rods
the local hydraulics place is big on voss fittings
so hopefully nut and olive might be easy
got ecu and all bits out way
but was stumped as not got a 29 mm spanner
sort it tomorrow
cheers |

Inch and an a eighth a/f will do it , you will have one as being of the thee and thys land you wont have thrown it away !
Compression fitting wont hold on the HP oil pipe at that diameter and wall thickness ,silver solder maybe ? _________________ 2 New Troopers ! |

If you wanted to go down the pressure test route, I work with a guy that is *beep* hot at brazing, you're welcome to send the bits to me and I'll get it done for you then send it back. Just a thought. _________________ 2000 3.0 Trooper Duty swb |

If you get the bits dan and show me how it wants sticking together I can soon get it brazed up. _________________ 2000 3.0 Trooper Duty swb |

I will chop a hp oil pipe up and see what wall they have
but feeling how rigid they are should be quite thick
I suppose its a case of what diameter the pipe is to suit fittings
might go the full hog and put a piece of flexy hydraulic in with T so car could still run
other than checking this orcv what other times would it be usefull to check pressure here ?????????
Yep have a 1 1/8 open end but cannot realy get in with it
so off to car boot on Sunday to a bag a 1 1/8 AF ring spanner setting the budget at £4 for a king *beep* or britool
also try and get some hydraulic pressure gauges too
cheers

double beep
not an 1 1/8 ring spanner anywhere
ended up sending for one off eblag
£15 for a king *beep*
I am hoping this is the fault.................

Just another thought I suppose this solenoid is triggered by the ecu
so opens and closes by the by plus and neg
so if I test to see its get signal first
then if its not getting a signal .............No oil pressure...........non start
need to look else where
or send it a fake signal to see if it starts
does this make any sense ???

Its more of a proportional control valve than a solenoid it varies the valves movement over the whole range by using millamps (0.000 of an amp ) just like the one on a Kawasaki KVD 130 hydraulic pump which is common on modern excavators.
If you put a 12v feed to it you might have trouble ! Solenoids are normallly just on/off
Connect a multimeter set to ma's in line with the coil feed and on the 0 - 250 ma setting and see if you get a reading when cranking,you need a good quality meter to see these low readings too .
Trouble is you can have the power at the coil but its no proof the internal spool in the valve is moving correctly ,this can show up on tech 2 as the % figure for the valve as its normally at 20% - 25% for starting but climbs as the rops says ' no pressure ' to the ECU up to 90% or HPOP fully open/max flow .
I have not had the HP pump to bits but from the manual I would guess its an axial piston type with a variable swash plate which is controled by the ropcv so no pressure from the the ropc to the swash plate ,no tilt on the plate , no delivery out the pump as its in negative swash ,no oil to the rail , no injector pressure .I have found that when you turn the key off the ropc goes to 0% so injection stops . _________________ 2 New Troopers ! |
