- Part 2 of the Bolinder Munktells typ 10. Made in 1947. 2 cylinder two-stroke hot bulb engine.
Pistons is now back in. Oil and bearings are fixed. A first start is not far away!
Don't forget to Subscribe for part 3!
Thanks! /Richard, Sweden.
I love this old tractor! It's so interesting! Twin cylinder with huge pistons, 2 stroke, 4 piston rings, pressurized lube system and a crankcase drain, it's all just so strange compared to a modern engine. I love it. I can't wait to see it running!
Yes these where almost unmodern when they came back in 1947. Real diesel engines already existed. But they where so reliable and never broke down so they became popular anyway. Very interesting design for sure.
Dont forget an early version of what we now call reed-valves.
@@thatdudeinorange2297 Exactly, i was working with the reeds yesterday. A big cast iron intake with 8 spingloaded steelwashers as valves.
I like your using the shim stock to keep the ring from dropping in to the wrong groove. Good tip!
Great tractor. Great work. Great camera!!!! Sensationell. Can‘t wait to hear the Munktell tucker away💪🏻💪🏻💪🏻💪🏻💪🏻💪🏻💪🏻🤙🏻
You sir under estimate peoples willingness to watch in real time you do this fine work. I have watched 100s of hours of a guy and his family taking transmissions apart knowing I will never do that. I just enjoy the art of mechanical things being torn apart or repaired.
I enjoy the sounds of tools doing their job and speeding up the video reduces that noise. A simple comment every now and again about whats going on and this would be mint..
Hi! Thanks for the input! When i put the video together in the studio it feels like many people would loose interest if it was in real time. But i understand what you mean, i clearly like irl myself if the content is good. I will think about it, and maybe make some irl videos and see what the audience thinks! // Richard
I watch you do this work and my heart is empty I miss doing this so much. Great video and thank you for sharing these my friend.
Where did you get new rings? I know Olsson i Ellös used to have them listed but not anymore.
You could have them made by any competent piston ring company today.
Those pistons look like they are in fairly good shape for being so old. The constant fresh oil going to them, on every stroke, must have something to do with this.
Plus quality metal made by true craftsman.
Was really looking forward to this. Keep it up!
Thanks for the great video, see you
On the next one. Love from Sweden
🇸🇪❤️✨
Great build. Watching every step.
Mycket intressant video .Jag jobbade med reservdelar till Volvo BM på 70 - 80 talet . Det fanns forfarande bönder som använde BM 10 i dagligt bruk .Det gick att få tag i reservdelar då fast i begränsat antal. VI hade även en BM 10 som startades upp på årliga maskinvisningar. Jag följer dina videor då de är välgjorda och utan musik och annat "trams" Ha de gott....
It might be had you boiled the old rigs in oil you might have gotten them out. The problem here in America is on old equipment depending sometimes with weird shaped old rings you might never get another. So caution is our method here. Of course you might have tons of them there. But I have seen people have to pour new cast iron rings. Machining can be touchy.
Yes maybe, but i had already made new rings for it. Cast iron as you say. So they would be changed anyway.
I've made alot of rings myself for many of my engines. Smallest a 49cc engine and biggest 21900cc one cylinder. Rings big as a steering wheel. It is a fun job making rings, if you have the equipment needed ofc.
@@YesterdaysMachinery do you have a video of you making rings?
Just stumbled across your channel. Looks like I'll be hanging around for a while!
Thanks for the video!
@@dans_Learning_Curve Hi! No not yet but people has been asking for a ring-making video. So that will come in the future 🙂
Excellent craftsmanship. The plumbing of the oiling system was very impressive. Can't wait to see/hear this engine restored to running.
Are the connecting rods made of bronze since I do not see bearing inserts just shims??? How about the piston rings indexing positions, does the manual mention anything about that specification ???
The use of castle nuts with cotter pin on the threaded rods is really a nice touch.
The part that amazes me is the use of the dry sump oiling system (equipped with a viewing window outside in front of the tractor) that far back in the day. This company must of been really ahead of their time. Shame they were bought up by Volvo and made a subsidiary company under the V umbrella.
Nice job Richard. Keep up the great work fella.

Excuse my ignorance. So, there’s no torque specs on the rod cap bolts? I’m used to building newer engines and that amazes me. You just snug them down til it feels right? Pretty neat brother. Very cool learning about this old tech.
I am restoring a 1939 John Deere B tractor and the rods and mains were "babbit" or poured bearings. They are installed with brass leaf shim packs so you can adjust them for wear. There is no torque. They use castle nuts with split pins. It cost me 700 dollars to get them restored.
OOuh, thats expensive. I pour Babbit bearing myself for my own engines and machines. Lots of work and time consuming. / Richard
Good stuff Richard. Is there locating pins in the ring grooves to stop them turning into the exhaust ports? And did you use that big end shim that you found in the sump ?
Hi! Yes there is locating pins. Yes i did, you can se the shims laying on the bearing when i mount it from underneath. I think they have made new cast babbit bearing for it sometime. It looked really good with no play. So that is nice. I have done it before but it is much work to make and fit new cast babbit bearings..
@@YesterdaysMachinery Hell yes it is! I've seen it done on a Ford Flathead engine before. It's almost getting to be a black art these days.
I like engines!
I Love Engines!
We all do
i think it would be better for the tractor and yourself and your subscribers and your youtube channel monetization if you did a complete full total restoration on nice unusual charming old antique tractor like this one....instead of 3 videos you could turn the project into 15 or 20 videos and do a complete tear down and full restoration....clean up and de-rust all the metal and prime and paint everything and reassemble...put in original or near original replacement parts as needed....do a full rebuild on the transmission and a full tear down and rebuild on the whole engine with a nice internal external paint job....i like to watch that kind of skill and i think many others do too.....you could completely disassemble the whole tractor and rebuild it to a like-new condition, especially such a strange machine with such wonderful basic analog technology everywhere and normal old fasteners.....when you were done with a full restoration you could probably sell it to a collector for a nice profit...............anyway thanks for the video and that's my 2 cents worth
Hi! Yes but this one is unrestored. And i never paint unrestored original objects. If it would been painted before i could do it. But for collectors here in Sweden and like myself, repainted tractors in not interesting to collect. You can paint a tractor any day, but original is original just once. Even if you make it like new.
I like painted old timers too, but not better than this.
But i sure could make a restauration on the mecanical parts. This is just "get it going for 0 dollars". But maybe in the future i can restore it.
I sure understand what you mean!
When you describe the engine as crude oil engine , It's diesel , kerosine or unrefined crude oil ?
All of the above... They burned a multitude of oils.
Really enjoying watching this stuff excellent content.
Thank you 😊
Good idea putting the tube fitting in a socket before soldering.
I didn't realize at first the little ends of the oil lines were brass fittings. Thought we were going to see you work a flare kit.
Awesome to follow along with this project really interesting , was there a torque setting for the conrod bolts? ..🙂
Hi! Thanks 🙂 No there is not. Just tight and then you have to adjust the nuts anyway to get the locking pin in.
Que tipo de acoplamiento esta en el tubo antiguo en el minuto 2:20
Love this. Can I ask, what were you checking when you slid the rings into the cylinder at 15:00?
Thinking about it, it must be the clearance between the ring ends
@@technic550 Yes! There must be a gap so the ring can expand a little when heated up.
@@YesterdaysMachinery thank you. Can't wait see see and hear it running
@@YesterdaysMachinery Is there a formula to determine the correct gap/range of allowable gap or did you find it in a book/manual? And what is the value?
@@dwightcarlson7136 It depends on the end use of the engine,(N/A, forced induction, nitrous, race, street). Then there are different formulas for the ring material used, and bore size. This applies to today's engines. I'm not sure what the measurements for these tractor engines are.
very educational. Thank you
Copper nickel.....you cant beat it.
Roligt att se nån som jobbar med äldre maskiner. Min pappa hade en BM10a i börjanav 70talet som jag var med och startade ibland, fick stå på framhjulet och hålla i blåslampan!
Lite tur, när jag sett färdigt del 1 hade du precis lagt upp del 2 :-) Har länge varit sugen på en BM Tia, borde kolla om Holger har något lämpligt ojekt att släpa hem i garaget. Blir kul att se om du får den att vakna till liv. Tummen upp!
i like olds stuff ,, I am old stuff LOL ;-}
Next time you work with iron rings use feeler stock to install the rings, less chance to break them.
Another good vid!
Your skill level is awesome 😎 the old machines were made to last, and in your hands they certainly will.
This is very interesting, I have never seen or heard of this type of tractor. Thanks for sharing with us!
Have watched each episode of this old tractor repair very interesting u r clearly a talented man👍

I have an old book titled 'The Burning Coast' by a British Naval Officer who was stationed in North Africa during World War Two.
His command was an old wooden schooner owned by Italians named 'Tre Fratelli' or 'The Three Brothers' which was commandeered by the British after which he patrolled an extensive length of desert coast with it.
Apparently the vessel had an old Bollinder hot bulb oil engine in it and he wrote that in order to go astern the engineer had to shut the fuel off then wait until the crankshaft was at precisely the right point as the engine slowed down.
The engineer would then turn the fuel on again in order to make the engine start running in reverse!
Apparently a few embarrassingly heavy collisions occurred while coming alongside before the crew got the hang of the process.
Haha, yes thats how they worked! Bilinder Munktells was all over the world. Many marine hot bulbs were made here. /Richard
Legends?
Looking better all the time!
Yes, This will be a very fun engine to hear roar for the first time in god knows how long 😊
I can't wait, these types of tractors are very rare to see in the U.S. :)
@@kevinf92 Yes i dont think that Bolinder exported many of these to the U.S. But they was made here in Sweden so here is a couple, but still quite rare 🙂
I don't think so either, and it's very rare to see any hot bulb tractors here.
Seems like we went straight from steam to gasoline to diesel.
I would wager that not one of those was ever imported to the USA . I think it is supper cool.
There are some here in America. Ive seen them at a few tractor shows.
Good...🇬🇧🙂
Thank you 😊
This is a very interesting build!
You can buy a cheap tool for fitting rings on ebay , ring expander
Already got one, but i wanted to do it like this, a bit more careful. They dont sell piston rings for these, so you have to make your own in the lathe. I didn't want to make more than needed 😁
Yesterdays Machinery Ive never seen anyone make rings that would be a good video
@@bigears4426 Yes i have thought about that also. Will do in future.
I wouldn't want to use a typical expander with these cast iron rings. The rings break fairly easy. Putting them on by hand is easier on them than using an expander, in my opinion.
@@davelowets Ive made the rings myself because there is no new available. And as you say they are pretty sensitive. Mount them like this feels a little bit better. Even if a expander tool would save me like 60 seconds.
U.K. Built like a 'brick sh*thouse' (an old engineering term). Rather surprised at the design for 1947, looks like it should be much older. It must have been very reliable to have lasted so long. Nice job of restoration, I look forward to the start up.
