[@pliedtka]

I was stuck in the middle part closer to the east side. We had Trabby - ackwardly the service manual was half useless - our car needed more advanced ignition timing and bigger gap on points to work properly - once I adjusted everything according to manual and my family almost killed me for messing up the car. Our Trabby run on 87 Oct 1/50 premix Ave 6.5L/100. I could take any Fiat 126 or Szkoda from light on 2nd gear. The crank common problem on with this engine but you pay for simplicity of the engine design - I also had Jawa 70 or 80 cc engine with carburetor mounted on the side of where the intake port was old and closed in exactly the same manner as on Trabby.

[@ams718]

Robert, I have serviced these (and other) engines numerous times. I would have a couple of suggestions that you might find useful. (1) Before you take apart an engine, after careful inspection, wash it thoroughly. (2) Before you remove any parts, make sure that you have collected all bolts, nuts, washers and other small mounting parts. Put them in a resealable bag, and use a duck tape to stick them to their corresponding part. After that, ALWAYS remove them from where they were mounted, especially when you are working under the car. Put them in separate plastic storage boxes. When needed, you can even stack them to save floor space. (3) When you remove a Trabant engine, you don't have to take out the transmission. Just lift up the transmission with a hydraulic jack and they come apart easily. (I can't exactly remember, but you might have to remove the transmission's mounting nut from the rubber shock absorber in order to gain adequate clearance.) Remove the cooling jacket, turbine, starting motor, dynamo (yours is a 6V DC generator though), ignition system, while the engine is still in the car. And yes, you can take it out on your own, without using an engine hoist. :) (4) When you are servicing a any small engine, mount it in a bench vice. It will save you from an awful lot of struggle. For the Trabant, you can us a simple L-beam. (5) Those 2 large holes on the flywheel are made precisely for that purpose. Only that, you MUST turn the crankshaft to a position when they line up horizontally with the engine's block. (so that you wont break the ring underneath) Put two bolts in them, tighten them firmly, then put a short piece of brass rod inside the crankshaft's centre hole and hit it with a hammer. The fly wheel just pops off the taper without making any damage. (6) The side way movement on the left conrod is just on the edge of being faulty, the right one is good. (7) The crankshaft bearings do need a replacement. If you have the replacement bearings, you can pay a local machine shop to do it for you or buy a refurbished assembly. Some European machine shops who service them, even buy your used crankshaft. So don't take it to the junkyard. Remember, this is Trabant, everything is serviceable. (8) I see your window wipers are not resting on the bottom of the windscreen. Spray some water on the windscreen and observe whether the wipers can reach the bottom. If they do, you can adjust that behind the dashboard on the end of the wiper motor's shaft. (it's pretty tight in there, though, you might want to ask someone with smaller hands) Loosen the clamp, turn on and off the wipers. Allow the motor to return to its default position, also move the wipers manually to where you want them to rest. Tighten the clamp. If the wiper test reveals that the wipers don't reach the bottom, then you have to adjust the wipers individually. Fold them up and use a flat screwdriver to loosen them. Move them manually where you want them to be, then tighten them up. Good luck.

[@TheWinjin]

I'm just dropping in to say that you've done the Lord's work and this is what Internet is really for. Thank you.

[@tedmoss]

Everything you say only applies to organized people, I know about you guys, every nut and bolt accounted for, I prefer to exercise my mind and remember where every part goes, if you don't have some parts leftover, you are not doing the job right.😁

[@MProper]

I've repair Trabant engines in the 80's, when I was young. Not for fun, I was a car mechanic. At the age of 19 I quit the job, never touch a Trabant anymore ... :D You say:"I don't really know what I am doing!" But you know how the 2 stroke engine runs, and I guess that's mutch more then the most people know. ;) BTW It's possible to remove the engine alone, without the gearbox. By hand! I have done this a hundred times ... The flywheel goes loose with a few decent (1 Kilo / 2 pound) hammer whacks near the starter gear rim. And of course, there is no reason to remove the whole exhaust! :D Important when assembling: The rotary valves must be installed with the missing corner in the direction of rotation. Align the cylinders with the exaust manifold, and then tighten. Otherwise the elbow on the manifold flange may break! (It's made of cast iron.)

[@manfredschmalbach9023]

Sounds reasonable. "Can't build it bullet proof? Then build it easily workable and repairable at least!"

[@captainchaos3053]

john jay The problem with all modern engine repair is the electronics. BMW v 12 is still only a rotating mass with valve control system and ancillary components. Maybe more to understand but still mechanically quite ordinary. 2 strokes may only have a few moving parts but setting one correctly can be difficult and performance 2 stroke engines are a lot harder to tune than 4 stroke engines.

[@captainchaos3053]

john jay Yeah, modern cars have gone backwards in my opinion. I had a lot of older cars and bikes that did better mpg and like you say started ran and never give trouble. The BMW model you speak of is such a low stressed motor and that's why it has little problems. The components are capable of taking double the stress of the factory tune.

[@captainchaos3053]

john jay Or do like I did as a teenager and resell it into a kit car and if you really want to leave skid marks (on the road not yer pants) run it on the 14" rims from an older 3 series. Speedo needs changed or ignored cos it will be wrong and you will lose about 25kmh top speed but the are like a go kart.

Trabant, the German Muscle Car ^^ mit der Kraft der 2 Kerzen :)

[@bunberrier]

I love simplicity. That is a work of art. What a fantastic car.

A few things about two-strokes: 500cc when well tuned (or even 600cc) on double bangers can produce an astounding amount of power (250cc on a single cylinder can produce well over 45HP). There's no such thing as a "factory tuned/jetted carb" or even a stock jetting, use the stock jetting as a North and adjust from that. Every two-stroke is different and you have to go from what the engine and spark plugs tell you. If the engine sounds like it's cutting revs at wide open throttle, it's rich. If it starts to lose power at wide open throttle, it's lean. A light-dark brown plug color is ideal. (And yes, when tuned it's still going to chug through an entire tank of gas like nothing) Change every goddamn seal you find, otherwise you will regret it. Hard starting is very caracteristic of: I. Low carb float level; II. Rotary or reed valves not sealing right; III. Too small of an idle jet. A good idle is set so that the engine doesn't take long to return to idle after a good rev-up, but doesn't drop to idle too fast. If it drops too fast, that means the idle is rich and will you also feel a sluggish and delayed engine response, leaning it to the right point should result in crisp and quick engine response. Just blipping the throttle when coasting is enough to lubricate the engine. (Just give the gas pedal a very, very quick pump every 5 seconds or so, no biggie). Two-strokes like to rev a little high (Well, the Trabant's redline has to be around 5000RPM or so) and have absolutely no torque below their tuned RPM, when you reach the tune RPM you will feel like someone opened a NOS can into the engine (Unless the exhaust is restricted like stock mufflers normally are, which in a way makes the engine feel to have a much wider powerband. Try searching for an alternative "racing" expansion chamber if you can.)

[@tauncfester3022]

Andre: You know very little about these old school, Schnerle ported engines.. They're rotary valves so no reed valves, they're old school long stroke and make most of their torque from about 2000 rpm up, very tractable and wide powerband. much like a Jawa 250 or Vespa 200. You can also just shift to neutral or open the enrichment ( choke control ) a small amount on a downhill. Blipping the throttle while it is in gear is stupid, it unnecessarily peak loads the engine bearings and drive train. These engines don't like to be revved "a little high'. It does them no good to wring them out, you unnecessarily are wearing the piston ring lands over revving it. The recommendation of expansion chambers is the dumbest suggestion. The exhaust manifold heats the interior, you'd lose your heater and defroster, and you'd spend over twice the cost of the car having a custom shop build a pair of chambers for this, and once finished the tuning involved would take that nicely tuned, broad powerband and make the car nearly undriveable. Oh and my bona fides? Oh about 20 years of driving and repairing SAAB 2 stroke cars.

Well, what do you know. I did say "Rotary/reed" mentioning that a two stroke can use either depending on the application. What is the redline of an engine like this one? Does this engine have a "wide powerband" because they limited the engine where it could peak like a normal two stroke or is that a característic of the exhaust or what? I did say "every two stroke is different" and I come from the motorcycle world.

[@immikeurnot]

@ Looks like the Trabant revved to maybe 5000 RPM. Info I found shows torque peak at 3000 and HP around 4000. That strongly suggests that you're right about the typical 2 stroke power band. Closing the choke going downhill is not the best idea. Good way to flood the engine before you reach the bottom. Better to occasionally declutch and blip the throttle.

@@immikeurnot You are right, peak power at 4000RPM. Wow, that's disappointing for such a promising engine. I would guess it's a supply problem to the cylinders due to less than ideal porting sizes, position and finish. Anyway, two-strokes have come a long way since the early 60s in these aspects, and being a cheap car, they didn't care about a lot of R&D to make these cars more powerful, they just wanted something cheap to last, and I would *love* to see someone improve the design and make perhaps a 100HP trabant some time :D

And yes, it would make the car literally undriveable without some common sense.

[@jocking3]

The first "muffler" in the exhaust system is actually not there to muffle the sound of the engine. It is a resonator. 2 stroke engines need a resonator for optimal work. If you try to run your Trabi without a front muffler, the engine will become less powerful (yes, even more), and it will damage the engine very quickly. Around the resonator is an outer layer, it's like a "muffler in a muffler", which collects the HEAT (not the exhaust gases, this system is isolated from the exhaust!), which is used to get some warmth in the interior.

[@Z4Zander]

@TheJR1948 , actually I understand completely. It is there to create a vacuum on the outlet of the exhaust and is tuned to the engine to accomplish this. This is called exaust gas scavenging, and is part of tuning the car for optimal power with such a small engine to get good fuel economy. Thing with the two stroke vs 4 stroke is that each time the piston goes down is a power stroke, and a 4 stroke it is every other time the piston is going down.

It was so nice to see this video (and of course, all of the othet ones too), keep up the good work. :) The Trabant will last forever! :) Greetings from Budapest, Hungary - from where this Trabant came from

[@Kryndon64]

I have no idea how I came across this video but I do have personal story which involved a Trabant. My great-uncle (grandad's brother) used to own one, but he had stripped everything in it (including the passenger seats) so he could load up food supplies for his little grill-place. One time he took me for a ride in it when I was real lil' and I was basically standing upright where the passenger seat was meant to be. Bless his soul, he made the best meat-sticks (it's a super common national thing) in the entire town. He did pass away quite a few years ago but I will always remember him for these things.

I'm from eastern germany, was born in the GDR. I love what you are doing! It's an oldtimer and it's worth fixing it. If i had only the time and the tools...

[@davidprice7162]

I've seen Robbie Coltrane lift out a trabant motor (minus the gearbox) out of a trabbie by hand, in his Coltrains planes and automobiles show from the 90s in the 2 stroke engines episode. So apparently it CAN indeed be done.

[@andrewretaylor]

Ok one final last thing... so your crank is the older style... the centre bearings can be fixed, you just need to remove the centre section cover, its just held together by the spring clip around the outside, you can then slide the bearing races to the side, as they are free floating.. remove the rollers, replace and put it back together... you can also replace the end bearings... (I would recommend recondition what you have, e.g. send your crank back to germany to have it professionally reconditioned. Danzer Autoteile is great and Trabantwelt do a good job as well. if you go the reconditioned crank route (there is no new cranks) they are all the newer style and therefore you also need a piston ring style oil seal on the pulley side, and you need to use a lathe to take a few mm off the pulley to accommodate the new seal type, you also need to drill a hole in the top half of the engine case to fit the centre locating pin on the newer style cranks.

[@mxss115]

I have just watched all four parts of your video and saw you happy in the end, thanks for the entertainment ! I had a Trabant a long time a go and I kind of miss it. I have never met a Trabant owner who was dissatisfied, you get what you pay for. As for the driving, never gear down to slow down, it will rev the engine with out gas/oil = lubrication (the freewheeling in 4th is for a purpose). Also fine adjust the gascable and idle to get a better response, a Trabant is very simple and needs basic adjusting to do its "best".

[@ChaosWolfJoe]

Aight buddy. I've seen a lot of your vids. Your attitude is realistic, albeit positive usually with a joke behind it. I hope you know that you look good doing what you do, and it's fun to watch and learn with you. Great vids. Keep 'em up, even now in 20203+.

From a news post on the Firefox browser home page (google "Trabant fervent") to watching you drive the car and now watching the complete engine tear down. Though I have worked on basic car maintenance I have no interest in rebuilding or even this car but ... it was a well done video and very interesting to watch. Great seeing it started and worked better than before after this task. I fix the odd appliance and it is always a great felling to succeed in keeping something going by using your own hands. Thanks!

Ok, so the things I noticed: - You can get the engine out without the gearbox. All you need to do is tale off the transmission's front mounting point's nut, and pull the mounting out it's hole, up and then right (towards driver side, which is right in front of you). That way there will be enough space for the engine to come out (don't forget to disconnect the ignition coil cables from the bottom). It is also easier to take everything off the engine while it's still in the car (generator, starter, carb, manifold, cooling vent and housing). - On the manifold, there's that "box thingy" around it which is part of the heating system. On the side which goes toward the vent, there should be a short rubber pipe between the manifold's "box" and the coolant housing around the engine. Without that short rubber pipe, the heating is waaaay less effective, so get one if you don't have one. Btw, the manifold is a thick cast iron, it can't rust through and let exhaust gasses into the interior. The part that can rust though causing that danger is the front muffler. - You don't have to take the exhaust off to remove the engine, just disconnect the manifold from the front muffler. Also, you can take off that black heating part from the front muffler to gain some space in the engine room while doing repairs. - You could've pulled that rubber ring out of the gearbox instead of cutting the gear lever. Also, try pulling from the inside next time instead of hammering the end. - All the bearings were shit on the crankshaft, even the first one you tried, it was just "less shit". They shouldn't have any noise whatsoever, they run in complete silence if they are good. - Don't forget to replace the 2 seals at both ends of the crankshaft, because their fault also can cause lean mixture. - When you reinstall the rotary valves into the engine, pay close attention to the direction you are installing them, because you can put them in the wrong direction. - The 2 crank case sides weren't "glued together by dirt", they were glued together with a sealant/adhesive. If you don't have anything similar, you can always use wood lackquer (no joke). But you can use that paste kind of sealant they use when they assemble a differential e.g. - When you put the pistons back on, pay attention so the PISTON RINGS' ENDS MUSTN'T BE ON THE SAME SIDE AS THE EXHAUST PORT. I used uppercase, because this can easily kill the engine, it's very important. Btw, the "thingy that connects the piston to the connecting rod" is called a Piston Pin. :) - When you put back the air vent, don't forget that rubber strip that was placed between the vent and the cooling housing, so the vent and the housing can't rattle when they touch each other. - If you didn't loosen the front elbow pipe part of the carb, then tighten it up when you put back the carb, because it shouldn't come off that easy. - In this car, since it's only 6V, the 'alternator' is called a "generator", or a "dinamo" as germans (and I think most eurpeans) use it. A car's battery stores DC, and every elecric stuff in the car runs on DC. The difference between the 2 kinds is that a generator/dinamo makes DC and sends it directly into the battery. An alternator however makes AC, and a rectifier on the alternator turns that into DC before powering the car's electric stuff. Every 6V trabi has a "dinamo"(before 1983 if I'm correct), and every 12V has an alternator. I hope this tips will help you with the reassembly of the car/engine. :) (Btw, I don't know where are you buying stuff from, but if from trabantwelt.de, then it will be a nice pile of money, at least 600 usd with all the replacement parts and shipping. In the case if you buy the crankshaft from them of course.)
