What are you up to in the workshop?

Thermostart is the heater element in the intake manifold, it has a fuel supply from the injector leak off pipe. When the element is powered to heat, a bi-metallic valve inside opens up and allows fuel through to burn on the hot element. If this valve sticks open fuel will be pumped into the inlet manifold and pour into the cylinder through the valves in quantities greater than what can be burnt, it will then run down past the piston rings into the sump washing the lubricating oil off the liners causing the sump level to rise. Would take a good while for a lot of diesel to get through this way though. My money is on the injector pump end seal fitted backwards or a faulty replacement lift pump.
Usually if that malfunctions it will feed itself with diesel and the parish with smoke and the engine might go for a run.

He said he someone told him once it looks like the injector pump off a scania is off it. Not a great start. Hopefully it's not. It's an awful hard one to guess because it's just not a common yolk. Will have to see next week. May bring a battery and fire it up and see what he means.:detective:

Is there a worse fate known to man. Changing the pads on an old digger. From trying to split a link or cutting bolts to get the old pads off. Don't know which is worse, trying to get them all off or putting them a back on.🙈

To be honest I don't mind doing them , made a tool for splitting the tracks, I never took a proper picture of it in operation, remove 1 or 2 pads, place the channel under the chain, the groves are to stop the chain link from spreading when pushibg. use a HYD cylinder and a rod to push the pin out, I just use the hollow core as it is a good all rounder for lots of other jobs, the fist time they need a lot of heat. Not so much there after. Pad bolts gas is the best and quickest, I don't even bother anymore trying to put a nut gun on them to see if they will tighten.

Could it be the leak off line from the injectors runs through the head on that engine?

Surely whoever done the injector pump would run it up on a test rig so any leak would be obvious?

He was meant to have given it the works. That could be it too. Another thing to ad to the list to check. Thanks for the advice. :thumbup:

@Endah would you mind putting up a couple of photos of the workbench? Looking for some inspiration here
There's a few photos in this thread

Anyone know what the purpose of these sections are on the volvo loader? They seem to be filled with fibreglass and are in front of radiator. However they are disintegrating and the fibreglass is being sucked into radiator.

Someone just put steel bars into the l50b here

Had bottle jack on it was pressing the frame apart hammered opposite side of pin to shock it.
Did you take out the whole ram? Did you have much trouble with the cyclinder end?
I never took the rams off the main frame,took the pins out of the top of the lift rams,re-sealed them in situ.
A sign of incorrect washer number or injector depth is if the engine is idling for a few minutes and then you rev it up the engine it sounds rattley or tinny and smoky. A faulty thermostart has the same symptoms. Injector or lift pump seal or diaphragm failure rarely causes unusual engine sounds or smoke. There really isn’t any other place for diesel to enter the engine on this one, both pumps, the injectors and the thermostart. The air filter and engine and tank breathers must be clear also as these can cause vacuum and pressure in their own ways.
Had a thermo start fail on a 6.354 it was like the excess fuel button sticking in,was the best it ever started 🤣

Cav pump,I doubt it would be off a scania.

That's what I tried telling him. The more I ask about it the more confused I get. I think looking at it in person is going to be the only way to determine the problem.

I wonder would he give me a lend of the welding table.

I'm in a heavy cycle of chickens and eggs. too many jobs going on at once.

Working on the van most of the time but had to pause that to tidy up after getting a hedge beside the house cut at the end of feb. why we never manage to keep it managable I do not know!!

have some other garden jobs that have to be done, it's the time of year for it.

and now the patio job we've been looking to do for 12 months is starting on tuesday which means I need to move some stuff around the yard but my jeep is unwell so I've had a hitch off a ford 2000 under the bench for about 10 years to be modified to fit the 20. so now's the time to finally fit it so I can move the trailers around to make space for the building job.

I have part of a stool hitch that came off the 20. bit of time with the plasma, mig and grinder and the mounting plates of the stool hitch with appropriate holes are now part of the 2000 drawbar.

Not pretty, but will be more than good enough for occasionally moving a trailer around the yard. and the ridiculously long drawbar will give me savage lock when reversing

Anyone know if the driven top hat on a Class contour disk mower can be taken off without removing the gearbox above??

I know there's a shaft with two Uj's in there. But don't know if it can move far enough away to remove the disk to get at the seals underneath.

Maybe drop the bed a few inches?

That is an option.
Just hoping to get some insight into it before I get ripping appart!

I have a bad tendency to over think the whole situation and make it harder than needs be!😂

Think the UJ shaft will only shorten by a cm or so without removing anything big, only three bolts on the bed on that end so dropping it down should be the easiest option.

I got the catros finished finally there Wednesday, it’s not the prettiest looking one but I know all shafts, bearings, seals, and discs are perfect on it. Note to anyone buying a second hand disc, don’t. And if you do, don’t go opening every bearing to try get it Perfect, just wait for it to fall apart and do it bit by bit
