I did get the blade. I actually have had the blade since christmas.

I took it al apart and sand blasted everything.

I had to make a few parts for it and I also welded

a few extra steel plates inside of the swivel frame.

I also had to make a latch to hold blade in place.

Someone had put a bolt through the plates

to keep the blade from turning

Well it looks like the fuel injection pump is bad.

I've been soaking it in diesel fuel for 3 days and

I have tried to get it to pump but no good.

I have it completely submerged in fuel and when

I push down on pump air bubbles come out

around the tappets. When I take it out of

the fuel the fuel drains out the bottom of

pump around the tappets.  I guess there

is some sort of seal in there that is shot.

Anyone ever have one of these pumps

apart?

Well I did work on the tractor today and my findings are not good.

As I said before the injector pump is shot.

Now what else I have found, there is no compression

in the front cylinder and the back on is low. The engine

oil is way over full and black as coal.  I have

both injectors removed and I have turned the engine

over with the starter several times and am not

getting any oil pressure nor any oil to the rockers.

The air filter looks like it was never changed and

the rubber gasket that goes between the filter

and the filter housing is hard as a rock and half of it is missing.

This thing suffers serious neglect. God only knows

what problems there are with the hydraulics and the transmission.

:(.. Sounds like the price is quickly rising from  $0.00, but machine seems to be in capable hands. Sorry to hear 'bout the bad treatment from P O.

I'm sorry to hear that this has developed into a big project. Are the parts available for you to rebuild it? Good Luck, Rick

How long has it been sitting dormant?

I'm not sure at this time just how easy its going to be to get parts. I did find a new injector pump

in Queensland Australia for $330 but that's not going to happen. I don't know how long

the tractor has been sitting. I was cranking over the engine last night and with the exhaust

system removed I put my thumb over the injector hole for cylinder #1 which has no

compression and I could hear air blowing out the exhaust valve. I removed the

head today and here a few pictures of that. You can see rust in the lifters for

cylinder #2. In the pictures I have the head sitting on it side and I have poured

fuel in the exhaust ports of both cylinders. The exhaust valve on the right is

leaking pretty good. The exhaust valve on the left cylinder is leaking some

which would cause that cylinder compression to be low. also the front

cylinder lifters look clean. Also a few of the head bolts were not all that tight.

What do the cylinders look like?

 

If the pistons and cylinders look bad, maybe you can use a swamp yankee technique that I've used too many times when parts were too expensive. You would need a ridge reamer, cylinder hone, and piston grove cleaner. Get the complete gasket set first. Disassemble everything carefully. Clean and inspect everything. There is a good chance that the rings were stuck in the pistons. Take them out of their piston carefully. Clean the piston grooves with the groove cleaner. Clean the rest of the piston. Inspect the wrist pin. Assuming that everything is okay, Clean the rings. Then rub the wearing surface of the rings with crocus cloth in the direction perpendicular to wear. Clean it again. Oil up everything and reassemble. New bearings would be good. Be sure to use plastic gauge on the bearings. For the head, just take it too a good machine shop for a valve job. Before tackling any of this be sure that you know how to rebuild an engine.

 

You may be able to rebuild the fuel injector. When you've got nothing to lose, try taking it apart to find the problem. A torn diaphragm can sometimes be replaced or remanufactured. Sometimes its just a torn seal. Good Luck, Rick

Too bad we don't live closer to each other. I'd give you your money back for the tractor :D and just stick a different engine in it. From my past experiences I would say take the engine completely apart and take stock of what you need before ordering any parts or even trying to locate them. Hope you don't find too much wrong with it.

Cylinders don't look bad and there is not much of a ridge but I will need to

run a ridge reamer around the top to get pistons out. I believe the rings may be

stuck on the piston in the front cylinder which also had no compression.

The rear cylinder piston seems to be ok , I can rock the piston

in the rear cylinder from side to side were as the front cylinder I can't

rock the piston from side to side at all and it should have some

side to side play. Those rings may be stuck. As far as the pump goes

I have looked at the schematic for the pump along with a parts list

and there are no seals or o-rings. I need to figure out how the

pistons/plungers inside the injector pump work without leaking fuel out.

You might check with a local diesel engine shop about rebuilding the injector pump. They may be able to get the parts through a warehouse that the public doesn't have acess. It sounds like its going to be a big project. The good thing is that it will be a great tractor when you finish.

Well I talked to my friend today about the tractor and I have new info.

The original owner bought the tractor new and used it for 20 years or so.

He died in 2000 and then the tractor sat under a tarp for the next

ten years. My friends neighbor bought it in 2010 and had

it running all be it only on one cylinder and then left it sit

until last fall when my friend bought it and it sat at his house

until I brought it home two weeks ago. I cleaned up the head

today and then I removed the exhaust valve that was

leaking. The valve was in nice shape but the seat was pitted.

There is no steel seat insert and the head has a seat machined it

to it so seat is cast iron and it pitted sitting unused all those years.

I lapped the seat and for about 7 mins of work it clean up

pretty good. I cleaned up all of the lapping compound and

reassembled the valve and spring. I gave all of the valves

a good slap with a rubber mallet to make sure the keeps

were seated. I put head on it side and filled the exhaust

port will fuel and it no longer leaks! Here are some pictures.

The last picture is of valve about 3 hours later and it just

a little damp.
