Poorly Wacker plate

[LKSF]

I think the fuel filters and supply is a red herring, that would cause loss of power, but not smoke. Engines only smoke when too much liquid is going in, never not enough.
White smoke is serious over-fuelling due to faulty injectors, slipped/incorrect timing and low compression.

generally I'd agree, but used to have a Cummins 240 in a 30t Grove, which'd white smoke (not thick, but white) if the filters were becoming blocked/she was starving of fuel (and obviously drop power) .. weirdly the 290 in the 45 tonner didn't do it, although can't recall ever having it reach a point of needing an urgent/unscheduled filter change
the plate is also losing power too though

One thing to watch out for on machines on sites is if they’ve had hvo in them aswell as diesel, I’ve had it a lot this year with the big generators, when it mixes can get a black gunk form which will only get worse when left sat, has said clear anything with fuel in even soak the injector in something if needed.

Used to work on these wackers years ago but I do t remember much more than the basics about them, we used to have 3 strapped together and run off a remote control to consolidate the track bed ballast before laying the railway, serious bit of kit

Mine used to be one of a trio.
Never had HVO in it. I have used HVO on a few bits of kit quite happy, it’s decent stuff but does have some different habits to Derv.

Hopefully you are wrong…. Dead £3K machine otherwise

Not if it's injectors? I understand engines very well, admittedly diesels less so, but can't you remove them, couple them up and run it to see what is going on?

 

[LKSF]

If they're dribbling or the spray pattern buggered then they need reconning.

What I’ve found though with the smaller diesel engines at least as the engine dies down it’s still pumping fuel just not enough to create a clean burn so the engine drops in revs eventually it jumps back up in revs but smokes like a trooper until it’s had a few good cycles then drops again, if there isn’t many good cycles it won’t clear however most of them eventually stall, another thing to oook at is diesel bug, not seen it in a long time but the colour of that filter isn’t normal,

Update - one of the injectors is 200 psi and the other is 20 psi. I have been avoiding it, but Charles had a go for me today. Radiator has ripped off the flyweel cover as well so need to open my wallet for some WN spares. £££££
Local Co. are looking at Injector.

The fan cover looks repairable if it comes to it.

I will see what the cost is first. Quite thin material and tight clearance to the flywheel so would need a bit of faffing. I reckon it will need to be at least £200 to make me think about it. Waiting to see how L&S Engineers come up, otherwise local WN agents next. The latter were pretty good last time I needed bits, but the former have been recommended.

£220+vat…

£220+vat…

Only you can make the decision between a new one at one end of the scale or just welding the bracketry back on (if it's steel) at the other.

Could you rotate the radiator slightly and make some more mounting holes or would it not flow?

make a small flat bar subframe .... mount the cooler to it with its original points and locate the new subframe to some better points on the fan cowl - 's only carrying the cooler

£225+vat for the new frame . Fabrication job it is

The roll frame is chunky mount something off that

I sold a non running one few years ago for 600 should have parted it out

Slow game that... and the bits everyone wants are usually the bits that are broken! Does yours have an exhaust? Looking at this photo some do and some dont. Wonder if its only needed for 2 of the 3 when running in a gang to avoid exhaust re-circulation? Or if its just one of those bits that falls off?

The engine is on anti vibration mounts whereas the frame isn't, wouldn't want to fix anything to the frame if it can be avoided as its trying to shake itself to death.

Yes mine has an exhaust

Yes mine has an exhaust

Mine doesn’t. So based on my theory then mine has either fallen off or was the LH one of the trio. Mine had the connecting bars on when I got it which are in my useful metal pile. Deffo was one of the outside ones from memory but not sure which end

Mine was right hand one also have the metal in my useful pile,

They’d all have to have exhaust on railway work wouldn’t be allowed by rules etc to be modified

Likely fell off or wasn’t replaced when removed
