Further to my original post here-: https://www.allischalmers.com/forum/new-member-first-time-allis-b-owner_topic202799.html I thought I'd best start a new thread in the Farm equipment forum to follow on seeing as that has developed from an introduction into progress/ideas to get her up & working again (And maybe even tidy her up a hair one day!)
Not a huge amount to this update, although I've got the bottom end back together now & given the carb a once over. Apart from some cobwebs & bits of seed it was remarkably clean inside and from the look of the brass parts I'd say it's never seen ethanol in it's life which would add weight to my theory that it was stripped and the engine rebuild fudged a lot of years ago. In other news, the fellow I bought her from may have located the head bolts and rocker assembly which would be a huge bonus so I don't have to fiddlefart around modifying the Ford parts I have dug out. On the magneto front, I'm not so hopeful of getting the original unit (and if I did, of it being serviceable) so with regards to that I may modify a distributor and go with battery ignition. The block has been tapped to accept a generator bracket so at least I can keep it charged easily. Even though I have no plan to fit an electric starter currently (pun intended) it'd be nice to have a reliable fat spark & some lights for winter time. Anyhoos, will post any other findings or queries that arise as I get to them. Oh boy, there will be some when I get to the water pump and brakes believe me on that! Cheers, Dan

for the distributor, there are two types of drives... One goes all the way into the timing gear area and is for the "normal" distributor .... The second time is a distributor that has a short shaft and two lugs on the end that LOOKS like the end of the mag.. and plugs into the MAG timing gear / governor shaft.

Thanks, I wasn't aware there was a unit that would be essentially a bolt-in. As previously mentioned my neck is a beautiful shade of magenta & I have a 4 cylinder Ford car unit on hand which I may modify to fit (remove vacuum advance, modify advance stops as needed, shorten the shaft/make a coupler that will engage the governor shaft & a bracket to clamp it in place.
I will however look into the "correct" unit as an option, you wouldn't happen to know a part number for that would you? Cheers, Dan

Quite a big day for the B today. Wasn't feeling great with some sort of stomach bug so elected to sweat it out by lifting the rear end up level, "installing" the right rear wheel (don't have a spline nut for that side, tube is shot & splines are pretty sacked out but it's a good enough placeholder) and then fitting up the bottom end/clutch assembly to the torque tube.
Will have to try and grab a photo but she's starting to look more tractor shaped and less like I dumped a pile of iron scrap on the front of the house! Rain stops play once again now, but managed to get the block covered & overall I'm quite pleased with the progress. Plus my idea of sweating out this bug seems to have worked, I'm feeling much better too! Manual labour, the cure to all ills...

I dont know of a specific part number for the distributor with lug drive.. You see them on e-bay every now and then... the "NORMAL" drive is more common. It can be switched over with a new cover/ shaft / timing gear...
I have considered a retrofit of an auto distributor before.. 4 cylinder (VW, FORD) or any other should work.... nice little project.. You want one that you can START about TDC, then have 30 degrees centrifugal advance by 1000 RPM.. Splines on hub shaft are a problme when the nut gets loose... If not completely destroyed, you can put a thick layer of devcon ( liquid metal) and put the hub and and snug it up good.. Let it set for 24 hours, then torque to 500 ft pounds..

Brilliant thank you, lots of good info there. On the spline situation, the chemical metal idea sounds like a good one especially since my tractor has the spline to 5 stud adaptors so that could be made a semi-permanent union. I think there's enough left to work with anyhow, most of the damage appears to be in the adaptor not the shaft & it doesn't appear to push too far on.
Newest problem (or not) is that on cleaning up the steering gearbox it was painted green, and on further inspection is actually a Fordson unit from a standard Major (especially weird, my first guess would've been JD or Oliver from the colour!) Fortunately the seller is a good guy & along with locating the head bolts plus possibly the rocker assy. & may be able to find the steering gear with help of his father on whose behalf he sold the tractor. For the moment I'll oil up the top end well, cover that & get to looking at the rest of the puzzle with the bracketry for the seat/tank,tins etc. and maybe look at the distributor. Really appreciate the help and suggestions, we'll have the old girl feeling better soon :)

Thanks Steve in NJ will check out your website but I think cost is going to factor your kits out sadly, especially so as we're in the UK (more's the pity!)
Also even if I was able to spend real money on the tractor, it'd be ruled out for the moment as I've just royally F'*£ed up while loading an old sofa onto our car & dropped a ratchet strap on the windscreen. Right smack in front of the driver, after all where else would it break? So I'm now working out how & IF I can even keep the tractor and afford the new glass... If every cloud has a silver lining, I should be making superb quality solder joints for years out of this one! Thanks anyway, appreciate the thought & will check out the website to distract myself...

Dan There use to be an Owner Registry as part of the 'Unofficial Allis' Website. In that Registry were over 20 Allis B and EB Owners listed in the UK. PM me your email address and I will send you a copy of those Owners. Gary |

Thank you Gary. will shoot a pm across later on or tomorrow.
Not much to report on the B for the moment, new glass for the one car is going to be around £400 or so (not claiming insurance, that's a joke for another time anyway!) hence have decided to focus on getting one of my others on the road since the work it needed for MoT (inspection) was only going to cost about £30 and a good few hours of sweat and blood. I'm well and truly spent now, having been rolling around on the driveway for the better part of the last week welding and throwing tools! But she's about ready now & should have a year's ticket on Monday so I should at least be able to keep the old B for the moment & maybe do a bit of R&R on that in the next week whilst the welding stuff is out front. Need to weld a nut onto the oil drain plug that's rounder than the tyres & one of the final drive pans is rusted through, not to mention what little is left of the tinwork.

Did you ever end up finding the last digit/letter in the engine serial number?

Oops, seems I lost this thread as I thought I'd replied already but nothing there! Yes I ascertained the letter (not number, thanks for the pointer wjohn!) is in fact a K.
Makes sense seeing as I've found kerosene/TVO specific parts in the pile of bits. Anyway, I've got a few photos of the tractor as it sits but will have to get them from phone to computer in order to post them. Also, now got a few little bits from a long dead MF65 diesel abandoned in the hills (Sadly the whole thing is returning to the earth, most bolt heads unrecognizable, 4.203 locked solid with moss growing from the exhaust and even injector lines rotted out) and it's neighbour, half of what appears to have been a 35 diesel with no cylinder head or front end. Not huge things, just a few fine thread bolts, block drain cock & a water pump from the 65 which was somehow still free. Why the water pump? Well the one I have is just the casing with no bearing, seal, shaft, hub or impeller. The only moving part I had was the adjustable pulley. I was originally thinking to use the shaft & impeller from the Perkins but as that would require machining the larger impeller I've had a look and I *think* I can actually make this water pump work on the B engine. Two of the bolt holes line up with the ones in the block, I should be able to "clock" it in such a way that the bottom hose lines up pretty good & I can make a backplate for it and block off two outlet stubs to direct flow through the block like standard. I will of course get photos of this spectacular rig-up if I get it to fit. Just over here doing what our forefathers would'a done to get by I suppose haha

Great! That all lines up then. The lower compression kerosene tractor engines were pushed for a while here but they seemed to decline pretty rapidly, maybe after WWII. As you get later into B production the K engines are much less common and they are mostly higher compression gas engines.
The kerosene engines have less power if they still have the original pistons but many have been rebuilt and changed out since then. Some other makes of tractors (IH, for example) also had different cylinder heads for distillate/kerosene. I think in most AC tractors it was mostly the pistons and manifolds which were different, and easy enough to swap out at time of engine rebuild. If you have all the parts to put it back to original that would be neat and worth doing in my opinion.
