You should fit new glow plug as well as cleaning air
Filter and fit new silencer as this one will be
restricted as full of crap

I like the Dexta because it has a draw bar rating of over 4000 pounds and a three point hitch rating of 2000 lbs.

I had the glow plug out on the test bench to make sure it functioned. Other than that, do I need to do anything else to it?

Also, I am not familiar with the "silencer" you referenced, can you pls help me out with that?

Thanks!

I believe that Derwen1959 is in the UK and therefore silencer refers to a muffler.

Thanks...new muffler with new exhaust pipes...the PO elected to put the exhaust out the top, but thanks goodness he didn't put a hole in the bonnet!

So, I am putting it back as it was originally..

thanks again!

Shep1,

Where are you located? State or part of the country.

Shep1,

Is your other beast a 3000 or possibly a 4000SU? I cannot tell from the pic angles.

n
Ok here is the latest. I left the drain plug out of the oil pan with a bucket under it to see if any dye colored oil would show .

The next evening I found maybe a cup of dyed fuel with a soot color to it also. Crap! So, after some fine wine..I decided that I could have residual fuel in the crankcase, so I left the bucket there another day. So, last night I looked into the bucket and it was just a tad of oil so I was right and that residual fuel just had to drain out.

So, I put a new oil filter in and new oil. Sprayed the injector pump springs, etc and put the plate back on the injector pump and decided to crank the old girl before it got too dark.

Well, crap again..no joy..the system has been bled really good, so what now?

As I was cranking I notice puffs of really fine mist coming out of "somewhere" around the pump area. Its dark now so I got a work light and saw that the plate that between the exhaust ports was spewing diesel. (really fine mist)

So, what does this plate cover and is there suppose to be fuel in there and since it is leaking could that keep the engine from cranking?

Lastly, to DL..I'm in east central Mississippi.

Another shot the "Beast"..It was sold to me as an "English Ford 3000"..It had turn signals, etc at one time. I completely broke it down, had the engine rebuilt, new clutch and sanded and repainted it..back in 1992. After I get through with "Glenda" I'm gonna clean put another paint job on it and repair a couple of greasy spots. I call it the Beast because of the pure power it has for such and old tractor..

Thanks,

Shep

What you have is a leak on the pre-combustion chamber covers, they can be
s-ds to seal at times. there is only a thin copper gasket and you have to
make sure the surfaces are clean. You will get a mist of diesel because
that is where the injectors squirt into. Once she is running you will see
a little smoke.

I would get her started and warmed up then go around the three studs and
see if you can get them a bit tighter and seal the leak before stripping
the plate off. If that fails, take the plate off and clean both surfaces
well before reassembly. New gaskets/copper seals are readily available
from any Massey Ferguson (spit spit) dealer as the MF 35 and 135 use a
similar engine.

You may not get her to start easily if the glow plug and fuel primer in
the tap is not working. Diesel sprayed on to the glow plug burns and
causes a flame in the intake manifold which is drawn into the cylinders
and fires her up. In some cases you can get away with not having this
system working in hot climates, but for me, any indirect injection engine
like the Dexta needs either glow plugs in every cylinder or the flame in
the manifold. Working on early Perkins engines, on which the Dexta engine
is based, on cold mornings we would hold a burning diesel-soaked rag over
the open inlet manifold to get them to fire up.

40 seconds on the heater, two pumps on the primer, listen for a "pop" in
the manifold then hit the starter and away she will go.

Shep1,

Other than the Dexta not starting most is great news. At least you now that one injector is working from the spray.

The reason I asked about your location was I wanted to see at what temperatures you were dealing with when cranking the Dexta.
Mine had little problem cranking in Southeastern Georgia most of the time, but cranking speed appears to be important on these. I replaced my primer pump/fuel tap with a straight tap since I did not need the glow plug and thus avoided problems with fuel leaks into the intake.

One reason these break piston grooves with ether is that the top ring lands are not steel as on the ford diesels like the 3000 and 4000. I have noted that most people use too much ether when trying to start a cold diesel. I have taken Majorman's advice and now avoid ether when starting any diesel. I just make sure the battery is fully charged and the starter is in good order and not dragging.

Majorman,

If Shep1 is not able to get the Dexta started is it safe to loosen one injector at a time to check for diesel misting? I know it does not verify that the spray pattern is correct. I just wanted to know if it could be used as a diagnostic procedure.

Thanks you 2 guys for chiming in...So, First I have never used ether on this baby and will never so lets put that to rest..I understood the PO did, but after I went through her she would crank without anything except a good battery! So, My worries about the ether although were well founded...it seems that she may not have suffered any long term damage..

This combustion plate thing is driving me CRAZY!! I have maybe 6 new copper gaskets on hand and I have yet to get this leak to stop.

I read about annealing the copper gasket which I did and that didn't work!

Ok, so the attached photo will show a small patch of where the fuel is coming from so..As best I can tell..But what sets my hair on fire is that this did not manifest itself until months of her running great and cranking with only a few turns of the starter...

Anyway, thanks to YT parts I have a replacement combustion chamber plate in transit..so, Jeeez..we will see when it comes in what happens...

Ok, guys,,the question for now is should she crank with this leakage? She is not even trying to come back to life while cranking..I have confirmed all 3 injectors have been bled ..






Thanks guys!

Shep

Shep1,

I guess my first question is when did the Dexta last run properly?

After looking at your "before" pictures of the plunger/barrel assemblies I think you were lucky that it ran at all. As dirty as it was in there you might suspect some water may have gotten into the injectors and nozzles. That junk had to have gotten in from somewhere.

You know that at least one of the injectors is working because of the spray from the combustion cap leak.

It is possible that one or more of the injector nozzles has become plugged or partially blocked even though you bled the lines to the injectors. Have you ever removed the injectors?

Since you have not removed the injection pump it is doubful the pump timing has changed and the diesel stop lever on the pump is returning to its run postion and is not stuck right?

Have you removed the valve cover to make sure all of the valves are moving?

That would be fine DL. Reading back, I get the feeling that the tractor
was running OK until it was stood up. Water in the injection pump probably
caused the plungers to stick and, even if they are moving now, water/rust
on the plunges can cause a lot of damage. We are talking very fine
tolerances in there and damage can occur within a few days.

My priority would be to get it running then you would find that the pre-
combustion chamber leaks would possibly disappear. Coupled with a bit of
hard work to get the carbon and gunge out of the system.

If someone has been using ether it is also possible that there are
internal problems.

What are the chances of a tow start? If she is misting diesel out of the
chambers she is obviously not firing and a tow might just be enough to
build up compression and start her off. I would also try a whiff of ether
just to get her running again.

Just noticed another point, Shep, have you had it running since you stripped the engine down? You may need oil in the bores if not as they dry out and will not build compression.
