Hello everyone, quick question about the rod bolts. On some rods are bolts that are loose (without play) but there is also one bolt with a little play, can I leave it as it is?
Yesterday while fitting the rod cap on the rod, I discovered that the bolts have a strong magnetic field!

little update. This evening I discovered a cracked wrist pin in piston No.6! It was cracked in the long way on two sides. What a surprise. Tomorrow the crankshaft goes to the engine shop for grinding, but only the main journals. I measured the pins, they all are 63,480 / 63,490. Out of roundness and...

Hello Emiel,

my 590E engine is of the later type (FL head, mechanical pump, top o-ring in block for cylinder liners), but I also have a relieve valve behind the distribution cover, and I believe in the pump if I remember well (didn't have a close look to it yet)

Hi Sandy, I eventually found the diesel dimension specifications on the end of the petrol section, thanks. Last evening a lay the crankshaft on the lathe and tried to clean away the ridge in the middle of the main bearings (oil groove reflection) with a small straight edge with oiled sand paper, but...

last night I removed the crankshaft. All journals look shiny, but all main bearing journals reflect the oil groove of the bearing liner. Most can be felt with a finger tip. I did some quick measurements with a screw type micrometer, and the diameter differences between high spot (not worn where the ...

Of course I can inspect the pump according the manual, but if the gap between gear and housing (radial way) is too wide, nothing can be done. In axial way I can resurface the parts with a surface grinding machine.

Hello everyone, thanks for your posts. I found the shims, but according to the Fordson workshop manual, sims are (end were back in the day) only available for the liners without the upper O-ring, so the older type. In my engine are the newer type liners. The engine casing is now empty, but is still ...

Hi John, yesterday evening I pulled 3 sleeves. They went equally well. I did see a horror video on Youtube from a lad who needed 1 day for the first sleeve to remove, including heating with a huge torch and big sledge hammer so I was pretty nervous. There is some sludge at the bottom of the water ja...

Hi shepp and Sandy, thanks for your responses. I'll measure the piston sizes with micrometer and decide. I want to replace all liners for sure. It is realistic the O-rings are water-tight because of the rust. I As for torque specs, can I apply the specs for the 4 cylinder? For the connecting rods I'...

Hello everyone, today I pulled the pistons out. The thin babbitt layer of the rod bearings were intact, not worn through. Some bearings had a very minimal line caused by a foreign particles or something. The bearings are original Ford STD, so standard size. Pulled one main bearing to judge the wear,...

hi John, the lubrication of the rockers worked still fine. I have a new radiator fitted but still the old water pump. Don´t know how badly the impeller is rusted, but a badly rusted impeller will work worse than a new one I assume. The radiator is new and later the engine will be new, so I think it´...

Hi Sandy, the problem is, you are never sure what are you going to do with the tractor. In my case, I want it mechanically sound and it's a hobby to use it respectfully but want te be able to use the full potential of the engine. It is a strange feel to me if not all components are matched to each o...

hi Sandy and Matthias. as I have a NP gearbox, I would like to keep the gearbox. In the future I plan to add a raised PTO so I'm able to use the tractor more like a modern one. I'm curious which clutch is now fitted, probably an original one. The previous owner of the tractor didn't know it was a li...

Hi sepp,

thanks for the advise.

I will stick with the rope seal.

forgot a question..

Is it correct there are modern shaft seals available for the crankshaft to replace the rope type seals? If yes, I assume they will also fit the 6D variant?and will it fit without further modifications?

Hi Sandy, thanks. There are bolt available, but I'll dive into this matter if applicable. It's a '64 engine with FL head, so it's quite sure the thick type sleeves are in there. Is it true that the camshaft bearings are not available anymore? I can't even find them in the exploded view drawings at t...

shepp, thanks for your post. At the moment my conclusion is that liner 4 has almost certain cracks. I did the dye test for a second time with great carefulness and even more protentional cracks show up. I showed the pictures from the liner to some mechanics and guys from quality department who do dy...

I think back in the day, the color also did change a bit between batches. This is a normal occurrence. A New Holland employee told me a few years back when I went there for Ford Tractor blue: "don't buy the paint here, because the paint we have at the moment is too purple. We sprayed a Ford a month ...

Sandy thanks for your answer. I seems the valve stem diameter of 9,5 mm is pretty standard, as my engine shop had a pilot for this diameter. So they might can get valve stem caps who fit. Yesterday I did some dye check after cleaning the head and in 4 of the 6 cylinders. After applying the red dye, ...

Forgot to ask a question

Anyone knows if the small cups which are on top of the valves are still available? (those where the rockers push at) These are different on the intake and exhaust valves. The ones in my engine are pitted and should be replaced.

thanks for your reply mister shepp. There is no sign of water in the oil, but all fluids were new so maybe the water had not enough time to migrate into the oil after 30 mins running. Today I will inspect the cylinder walls with penetrant fluid (red penetrant fluid with white powder), maybe a suspec...

Hi Mathias, I wonder if they can get the head tight for pressure test without resurfacing, but I let the company do that. Still have to scrape the gasket surfaces. The 6D and 4D engine parts are the same, just 2 cylinders more, besides of the oil pump which has higher capacity because of the extra b...

Today I inspected the head. Till now, no cracks found. I noticed that the valve stems of the exhaust valves are pretty worn (9,43 mm instead of 9,49 / 9,50). The carbon has an abrasive effect. The intake valve stems are very little worn (9,47-9,50 in diameter). I decided to replace all valves and va...

otherwise the engine is dry, so no leaks at the crank. The hone marks are still visible in the bores, so pretty good. I'll order this https://histoparts.com/H5911___koppakkingset-ford-6-cilinder/3?catId=1897 Tomorrow I'll number the valves and remove them and check the play etc.. Are these engines p...

Hello everyone! currently I am in the process of fixing a super major with 590E engine (FL head), cast sump. This week I started the engine for the first time in years. After bleeding the fuel system it fired up quickly and ran good. I put a new radiator and thermostat in and of course good quality ...
