The Fordson Tractor Pages Forum

Blueorange Your tractor is 62 years old. Just to give you perspective, Rolls Royce engineers dropped Merlin and Griffon engines from Spitfires for a rebuild after 200 flight hours. Gasoline engines, supercharged and overhead cams, but same basic technology. Your best oil pressure reading of 15psi is...

Our tractors are sixty years old.
Worn bores and reduced compression are inevitable.
Best, Adrian.

I share your embarrassment, JC!
Best, Adrian.

Kerry, if you work it, you'll love it! Look at the gears in the rear axle housing. This is a Sherman tank! The engine needs heavy work so as not to glaze up. After everything you have done, it would be a shame not to let the revitalised (by you) machine do what the Ford engineers designed it to do. ...

Love the colour scheme.
Love, also, that you are doing a methodical rebuild.
The NP Super is still a relevant and useable machine, so you have to promise yourself to let it loose on some serious work, because it will be more than up for it.
Best, Adrian.

A request to JC & 1su9, could we see some images of your tractors in the USA?
Tractors and where you are?
Best, Adrian.

Have you had the head skimmed, new valve guides pressed in, seats reground to mate with new valves?
Best, Adrian.

Sounds good, Rick. Did you make it work?
Thought I'd post this to give Mathias even more encouragement!
Best, Adrian.

Bucket correctly placed under the tractor, Rick, and most of the coolant is captured when you open the tap.
I forget exactly what kind of tap the Diesel Major has, but it's larger, isn't it?
Best, Adrian.

Yes, that's the one, Rick.
Best, Adrian.

This is what you need. It has 8 hours to run and there are currently no bids at £10. Seller says that it leaks. May be worn, may just need a clean. Your call. This is the original for your tractor - mine has the same. Best, Adrian. https://www.ebay.co.uk/itm/Fordson-major-brass-tap/223483482141?hash...

Invert the block and go in from the bottom with a wire brush wheel attached to drill.
Best, Adrian.

On this holy day, not a bad idea to remember that cleanliness is next to godliness! Hope you won't mind me saying that what I see in the photos is not the required level of cleanliness. Well, clean is an absolute, to be pedantic, so there is only one level! You must remove everything from the block,...

As you know, Rick, the various cracked petroleum products have their individual properties. I know a bit more about kerosene, but diesel is close on the spectrum, and shows similar entropy.
Basically, it needs using!
All best, Adrian.

Loving the pome and Norfolk lingo, Rick, though coming from silly Suffolk can't pretend to understand all of it! You and the Major a great combination! Yes, diesel when left to itself does do strange things. I treated the tank with some American sealer. Very good stuff. It takes rust particles out o...

A rebuilt engine achieves complete combustion, meaning full power is delivered and the exhaust runs clear.

A few more images to urge you onwards, Mathias. Before and after shots. [Spot the head core plug I forgot to replace, and which leaked on me when ploughing!] Best, Adrian. https://i.postimg.cc/JnztBdbq/IMG_4774.jpg https://i.postimg.cc/GhKgPcY4/IMG_4964.jpg https://i.postimg.cc/s2kTf1FN/IMG_4966.jpg

You're making good progress. Can't see the liner seal recesses clearly, but I'm guessing they are not eroded. All looks well. Now you need to clean everything in preparation for the rebuild. Have you invested in a new camshaft? Having gone this far, and having saved money by doing the work yourself,...

Sorry to chide you, Mathias, but one notices the absence of photos!
Best, Adrian.

What about the liners? Have you got them out? If so, how do the bottom liner seal recesses look?
Best, Adrian.

Hello Mathias The pump is held in place by the two bolts you mention. It is driven via a bevel gear that meshes with a corresponding bevel gear on the aux drive shaft. So in answer to your question, no, you do not need to remove the shaft first; on the contrary, you must remove the pump before the s...

Hello Bonkie
If I were you, I would not ignore the advice Shepp has given.
Most informative, Shepp. Thank you.
Best, Adrian.

James, my advice would be to learn to appreciate the tractor that Ford engineers designed. The extra power you wish to add will be out of balance with the tractor, and in any case you will struggle to convert that extra power into traction, especially given the lack of a diff lock. That's my opinion...

I used various shapes of wire brush that came in a kit to fit an electric drill. If you look at the photo I have posted, I cleaned everything on the block apart from the internal walls. Inside the block I felt for any loose flakes of rust and removed them with a screwdriver, but generally I was happ...

Just to help you spend even more money (!), you'll need new bearings + seal for the auxiallary drive shaft when you get it out. In preparation for the rebuild, you'll also need some Wellseal or something similar for the various gaskets, in particular when you refit the front mounting plate - the gas...
