Sounds like a good find. You'll need to look at other casting codes as well as the serial number. A fair mix of dates, but not conclusive without more details. What sump and mounting plate does it have? I suspect it could be a built up engine but more details will clear this up. By the time the bloc...

Only two gearboxes existed, they changed at 957E-63953. Super Dexta's have a different crown wheel and pinion ratio which makes them faster. No special fast ratios were made, certain countries blocked some fast gears to limit the top speed.

It must only move a maximum of 1/2" between the water pump and dynamo, and not just deflect. https://i.postimg.cc/L8b8HbBK/Fan-belt.png It is tight, and quite hard work to hold while tightening bolts, and that's with the narrow belt. less than that will cause the water pump to slip (especially with ...

That play is common but it shouldn't be there. The belt when new can somtimes require the dynamo to be removed from its front mounting to fit, but once over all three pulleys there will be plenty of space for it. It'll strech initially very quickly.
Sandy

Leaving the seal not fully seated is a common trick, but it doesn't tend to last well, for the seal isn't designed for such use and there are many pulleys (not your case) that have pitting which will wear away the seal in no time. Watch your front axle, it might well not take the relocation.
Sandy

I agree everything looks good. The cover wants a good clean before you fit the new seal, the gears and plate could do with one too but it's more difficult as it's possible for the petrol or paraffin you use for cleaning gets into the sump which you don't want. Just before final assembly give everyth...

Not a great position to be in. You'll now have to find new channels, the earliest ones didn't have the holes for the vacuum tank for industrial trailer brakes. You'll need to find out if yours had them or not. These holes are on both sides, roughly in line with the no. 4 cylinder. Some folk have mad...

I'm afraid I failed to remember two changes that do allow a later pulley to come off without removing the casting: The later pulley is smaller (7.52" rather than 8.8") and the later front casting has a recess to enable it to come fully off. You can see one of the dowels in that pic of Billy. https:/...

Is it a new one? If so I'm not surprised, repro quality is poor. If it's genuine it should take a fair load, but if you put your weight on it when getting on it can happen, for they weren't expected to take much weight, only torque for steering.

There's no spec on compression, the ratio is 5.5 to 1, and given that diesel usually needs 300 psi minimum and the diesel has 16 to 1, about 100 psi is a bare minimum. These are general minimums, and not official, so not a clear cut line. Ford never did compression tests, they generally preferred to...

If it reached 170ºF it does have a working thermostat (they normally fail open). Not great about the leak. The only breathing here is the connection between the rocker cover and intake manifold, timing cover breathers came in with the Mk2.Compression doesn't sound too great (but good that all have s...

Not great. Blowing through with petrol or paraffin is best. Then a squirt of engine oil in.
Sandy

I would agree it looks clean. A bit surprised the sump hasn't got red oxide on it but maybe it was cleaned very aggressively. The belt length is 42.9".
Sandy

Looks to me like you've had a diesel manifold fitted too. You'll need to find a petrol one, only available second hand.
Sandy

Jan has answered it perfectly, you have an extra shield fitted. Never available, not even on lorries.
Sandy

I'm afraid I can't give you sizes for we don't have any live clutches, but with the films and pics you should be able to work it out. The badge is particularly easy as it fits in the RH grille as you can see in the old posts. You'll notice the blue in repro badges is much lighter than that used on o...

That's good to know the NP colours are also available, we had to mix some up, but fortunately managed to get a good match very quickly. Just looked at some of your old posts, they both look great, lucky escape with the vapouriser.
Sandy

Very good points here. Even with that in mind fuel consumption will be an issue, these engines at best empty a tank in just a day of work (compared to a whole week for the diesel ones, and with a spare gallon still left).
Sandy

I don't mean adjusting, just that it's the right way round, though I doubt it'll fit the wrong way.
Sandy

Heat transfer is reqired by petrol, but far less than TVO. Here's a pic of Bob's Major showing what the petrol manifolds look like: https://postimg.cc/gallery/XvqVY6G#gallery-10 I do mean oil dilution, a big problem with TVO. Remember the manifolds and vapouriser are a single piece casting. Here's a...

Fuel consumption will be very high in the best of circumstances. You'll need petrol manifolds and a carburettor, as well as the air pipe.It'll never run properly with a diesel manifold, for it won't heat the intake manifold. Can't help with the carburettor any more, the jets and bodies are the non i...

Not really sure, there used to be a separate additive to add to unleaded petrol for old engines, but we've barely used it on our petrol engines and they're fine, but can't really answer. The timing pointer marks the setting required, but that might be any of the possible settings I mentioned or even...

I'm afraid No NP tractor had such badges or decals. The badge you posted was first used on Dexta's, and concurrently with Power Major's when in production. On both it was replaced by the decal on Super Major's and the restyle of the Dexta then, and in late 62 they were discontinued deemed unnecessar...

Very good to know it perfectly fits Ford practice.
Sandy

You probably won't find it by part number (88358-S). It's 1/4" in diameter, with UNC thread at one end, and UNF thread at the other. Total length 1 1/16". Can't help with the length of each thread, looks like 1/2" of UNF and 3/4" of UNC but you'll need to measure that to be sure.
