 Topic: The B Lives!
Posted: 02 Dec 2017 at 3:24pm |
Hey everyone,
After installing the new (to me) magneto, setting the timing and cranking her over about 6 times the old machine barked, stumbled a few times and caught! I semi-flushed the cooling system and put a screen in the radiator inlet to catch any junk it might have collected in the years it’s been sitting before this.
It didn’t rattle, and after it got warmed up the oil I have squirted into the cylinders over the years burned off and she ran clean and smooth. I put a little over a quart of gas in the tank from an old Briggs an ran it dry. Probably 15-20 minutes of running. The longer she ran the better it got. Made a few adjustments to the carb and timing and couldn’t be happier! Ran her up to wide open and idled as low as it would go without adjusting throttle idle screw. No problems of any kind.
Been a lot of stress and elbow grease, but this pre winter goal has been reached! I am one happy camper!!
I will warm the B up again and set the valve clearance, but I must have got it close at 15 thousandths cold.

Thanks! Glad you gave me the heads up about coolant. I will probably pull my DIY coolant filter tomorrow and see if my rat nest fears were justified, or another of my needless worries.
When she ran out of gas I checked the oil and it was still pretty clean and no sign of water. I had worried a little about those old sleeve O rings being brittle, but apparently they are OK. I still have to get the cooling system up to pressure to make sure as I ran it without the radiator cap today. I need to make sure there are no leaks anywhere else before I put antifreeze in. My screen caused a seep that can be seen in the video, but I ain’t worried about that as the inlet is sound and round. With that done I can rest easy over the winter, and just start it once a week or so.
I don’t think the oil pressure gauge works anymore as it didn’t show any pressure but I know what an oil starved engine sounds like, and saw oil being pumped when I cranked it by hand.
Timing the mag was surprisingly easy, and marking the crank pulley helped. Why the engineers at Allis didn’t do this, and weld a pointer on the front of the timing cover sort of escapes me.
Again, thanks to you, and everyone else, that has offered advice and insight that got me this far. I am so relieved!

This is a different type of oil system. Remove the filter and crank it over. If the pump is in prime oil will come out the filter stand pipe. If not you need to prime the pump. I do it by placing a gas hose over the stand pipe and filling it with oil, let it seep down for a couple minutes and refill. start the engine and catch the oil in a can that comes out the hose or have a hose long enough to go over the rocker arms. When you have oil out the hose replace the filter and start again and see if you have a reading on the gage. the pumps on these engines are not self priming.

Nice tip. I will remember that. I have cranked the engine enough by hand to WATCH oil come out of the filter stand pipe and the rear rocker assembly slotted stud. I know the engine is producing oil pressure and the pump is primed and working. I know what an oil starved engine sounds like, and it should be obvious that sound is not to be heard in my video. This engine has not ran for more than a few minutes in the last 30+ years until today, and it is highly likely the gauge has just given up.

My wife was shooting her own video, and when it fired I recreated the scene from the movie Castaway and yelled, “I have made fire!” while holding my arms up and dancing around. It was not planned. I am sure I looked stupid, but I don’t care.

How proud you must be.
Frankly, when I saw the first pictures of the unit I had trouble believing that anyone would accept that challenge.
tropod, You did and were successful. Congratulations!!
Another of my favorites back to life. Thank you so much.
Again Congratulations!!!
Good Luck!
Bill Long
ps: You know, Allis Chalmers made them good. A 78 year old tractor that must have been kept in horrid conditions brought back to life. Hard to believe.

If it wasn’t a family heirloom, and the engine had not been rebuilt just prior to sitting in the shed for decades, this wouldn’t be happening. I ain’t made of money and this has put a serious dent in my pocketbook. Aside from rims and tires I hope the major costs are behind me. Like I said I am mule headed, and when I put my mind to something it takes a great deal to stop me from seeing things through.
Luckily the weather has cooperated and given me enough time to get to this stage. Now I can ease off the pace some. Getting antifreeze in is my next goal, and I don’t expect and major issues on that front. The water pump was the first new part I bought when I started this project, and while beat up the radiator is still sound. I need to clean up the mounting steel and repaint the whole thing, but compared to some of the other parts it is nearly new.
If I hadn’t found this forum, and learned so much from the knowledgeable members here, I would have probably screwed up the tractor beyond all hope. Y’all better know I am not so arrogant that I don’t respect and honor this fact. You guys need to take some pride in this project because you’ve helped me all along the way. Y’all rock!

Got out and fired the B up again this morning, and she won’t need applying the choke unless it is really cold. I choked it full closed on one crank and then opened it to half way. On the next compression pull she fired right off, and started stumbling in 10 seconds or less! As soon as I opened it up she smoothed right out, but it is at least 60° here this morning. The exhaust has cleaned up really well and only puffs every now and then when it misses, which isn’t often. Running wide open she doesn’t miss a lick. I can tell by the way the cranking feels that runnng for a while has freed up bearings, rings and such. Between compression pulls the engine just falls over now, and there was some resistance before.
The oil pressure gauge is officially shot. I know because I attached one of those induction tach/hour meters where a wire is wrapped around a plug wire and the pressure gauge neddle doesn’t move off zero at any rpm. There isn’t any rattling, or bottom end rumble, no matter how slow or fast the engine is turning. The loose radiator makes more noise than the engine rotating/moving parts.
The engine idles down to around 800 rpm and tops out at full throttle at almost 1,400, so I know the governor is working. We’ll see for sure when I get her rolling and put a load on it.
My DIY coolant filter made out of screen wire mesh did catch some crud, but no rat nest stuff. A few big beetles, a couple spiders and rust flakes was all it had in it. I cleaned it out and reinstalled it just to be sure. I think running some flush juice through it might be a good idea.
I let the B run for about an hour today, and varied the rpms every few minutes. I know I should run the valve clearance, and I will after the next run. The oil has turned a little brownish, but the level hasn’t changed. After I run the overhead and get antifreeze in her I will probably change that oil out and probably get another filter on there.

GREAT!!! You did a good job and learned along the way, you should be proud.  Idle should be 400 to 500 RPMs. Doesn't that purr sound make you feel good! And NOTHING sounds as good as an Allis when the governor kicks in!  PS,,,,now I know what a chit eatin grin looks like!!!

 Here is my DIY coolant screen filter I jammed into radiator the inlet to catch junk. This is after the second run and has about 1/4 as much stuff as after the initial startup.

Great to hear the B fire back into life! Easily the most rewarding part, getting them back running again.

X2! Whether it’s after a 30 year slumber or after a fresh rebuild, hearing it run correctly for the first time is a feeling like none other! Especially if you’re the one who made it run!
