REBUILDING A BMW AIRHEAD ENGINE IN 30MINUTES

In the last year, I meticulously disassembled, cleaned, and diagnosed the classic BMW R60/5 airhead engine from a 1970s motorcycle, embarking on a journey to restore it to its former brilliance.
Throughout the process, I repaired numerous internal components, ensuring their optimal condition for seamless reassembly.
Given the odometer reading of well over 90'000 miles on the original engine, an extensive rebuild became a necessity to revive this vintage masterpiece.
Join me in the fascinating restoration of this iconic motorcycle, where every part tells a story of its enduring legacy on the road.

The print shows the cylinders staggered, Great job.

[@WorkshopRebuild]

This engine features staggered cylinders and the blueprint highlights it well. The blueprint is a factory drawing from 1968 and it showcases an R75 which is a 750cc engine. Thanks for your feedback!😃👍🏼

[@oldleatherhandsfriends4053]

Those WW2 engineers really carried BMW into the 90's. That engine is beautiful and you can see the quality.

[@WorkshopRebuild]

You are right! They left behind some great technology and great manufacturing methods. There were numerous changes that took place between ~1960’s and 1995. I will share more details in an upcoming video series😃👍🏼 Regards Andreas

As a retired Dealership Harley-Davidson mechanic (not a damn technician) with over 55 years of service and repair under my belt it is wonderful to see young people doing work with the attention to detail as I have seen you preform on this engine. Nicely done. I wish there were more young people such as yourself in the shops in my years. With work ethic such as yours I know you enjoy doing it for year to come. I hope only the very best for you. God bless, Most Sincerely, Pops

[@user-wz8gm5rk9u]

Im doing all my engine work, slow and thoroughly, but the maddafackas bossing around with me hates it, ive never got a complaint from any customer yet though 😊. I love doing my absolute best, every time and i take pride in learning from the elderly (or youngsters) who is proud, quality minded mechanics that do their best eeeeevery time doing engine work. It is the absolute best feeling, to deliver a piece of work, that you just know, wil last a very long time and perform the same or even better than a new engine if taken care of proper.

This engine contains numerous M6 and M8 bolts that directly thread into aluminum. I prefer not to risk using an impact gun on them, as stripping the threads could lead to a challenging day, to say the least! Thanks once more! Regards Andreas

[@Freba66]

In the nineties I was team leader of the Police motorcycle team in Amsterdam. We had 35 solo motorcycles and 23 sidecar motorcycles. All R60/5. Lateron the K75 and sidecars from EML with R75/5. And in 1969 I learned to ride a motorcycle with the police with the R50, which at the time also had a sidecar. Great things to transport the detainees with their heads down in the sidecar during the student riots at that time.

[@WorkshopRebuild]

Wow, what a story! Thank you for sharing this in the comment section, Sir!😃👍🏼 Besides the Police team, did you own a personal BMW Airhead or possibly a K-Bike? Regards Andreas

@@WorkshopRebuild I have owned a K100RS twice myself. Lots of vibrations in the 4 cylinders. Oil consumption. I enjoyed the Honda VFR and the KAWA ZZR 600/1100 more.

[@WorkshopRebuild]

Did you own the one of the early K100RS bikes with 2-Valves per cylinder? Very interesting bikes, unfortunately I‘ve never been on one of them before. The K75 doesn‘t get as much love as it should, because everyone is automatically drawn towards the 1000cc engines…maybe that will change as time passes☺️ Thanks for sharing!

[@grandmagrandpasbucketlist]

Well done, Andreas, I like your attention to detail, from, “what looks the vapor blasting of each piece”, and finished with what I am guessing is a Cerakote, to your “special” assembly tools, the initial assembly lubrication and temporary plugs, all these are signs of a good artisan. Given the age of the motor, I am amazed at the perfect condition of the thread on the aluminum head exhaust port. My 2c, as a firm believer in “copper slip grease”, I used to use that on the aluminum exhaust nut to aluminum head thread, as well as on the spark plug thread.

[@WorkshopRebuild]

Your comment means a lot to me and it also keeps me going! You mentioned every step from the preparation to the final result, which means you have been watching many videos. Thank you for your support!! The cylinder head threads were not reconditioned whatsoever, just cleaned and prepped for the coating. I was actually impressed by the condition, because many airhead owners have to build them up with weld and recut them! I fully agree with you about copper slip grease (copper coating). This should be applied to all fasteners along the exhaust system, including the exhaust nuts. I will be doing this once I install a brand new exhaust system to this bike. Have a fantastic day and I hope to see you in 2024. All the best - Regards Andreas

I've never seen a motorcycle engine with a brushed alternator before. I would imagine it has a very robust charging system. Outstanding work on the build!

The alternator is quite robust and it feeds enough power back into the system. If one would want more lights or go above and beyond the original setup, then it’s well worth upgrading the alternator.

[@carlyleporter5388]

Took me back a long way. I never worked on that part of my R65. I put 200,000 miles on it and sold it. They say you can't wear a BMW out, but mine was wore down to the nub. But I took the engine for granted. Never had any problems but for the rocker arm assemblies wearing out. And I worked on it a lot. Clutch cables, brakes, forks, alternator problems, throttle gears, fairing mount welds cracking and those back sub frame welds cracking. Always cleaning those Bing carbs. But I guess they're one fine motorcycle all considered.

[@WorkshopRebuild]

It sounds like you had quite the journey with your R65! Putting 200,000 miles on a motorcycle is a testament to both the rider's dedication and the machine's durability. Despite the wear and tear you encountered, it's impressive that the engine remained steadfast. Your experience highlights the maintenance and care required to keep a motorcycle running smoothly over the years. It seems like you've had your fair share of adventures and challenges with it, but as you mentioned, BMWs are renowned for their resilience. Thank you for sharing your story! Regards Andreas

[@carlyleporter5388]

To be truthful, the 200,000 miles is just a close estimate. The odometer stopped working at 31,000 or so miles. But I knew how many miles I had to buy a new rear tire, seems like it was close to 10,000 miles thoroughly worn out. I kept the old tires in a stack in the corner of my shed and when I finally sold the bike and hauled them off, it was close to a pickup load. The mufflers like to rot out on them too. Not inexpensive to operate. Seems like 45 mpg was about as good as I could get driving like grandma. The full fairing was probably responsible for the gas guzzling. In summer, feet get uncomfortably hot on long rides. If caught in the rain, the fairing would keep you dry with the right posture as long as you could keep moving. Boots would fill with water however. Hydroplaning would scare you into a coma. Once you get familiar with them, they're really simple to work on. But if you use one to commute, plan on working on it. Yourself. Unless you're rich. @@WorkshopRebuild

That’s a lot of care assembling an engine with an aluminum crankcase so porous that its bottom always has oil on it - seeped right through the metal casting itself. I used to own a 1969 airhead and I was amazed that the metal quality of the crankcase could be so bad. The drive shaft housing was the same. Nice set of special tools used!

[@WorkshopRebuild]

I heard about this issue with the early models from 69/70. Most engine castings would leak around the engine mounting stud bores. They quickly made changes to the 70/71 model engines to improve the castings. I haven’t heard of issues with the swing arm nor the final drive. Maybe it was just the gasket that was placed between these two parts. Thanks for sharing your experience and leaving a comment! Regards Andreas

I have a full engine rebuild video about this engine, which shows every step of the assembly. Fun fact: Piston rings rotate on pistons and within the cylinder bores. Even when installed 120º apart from each other there is no control over the ring gaps after that. It's very possible they line up after every now once the engine is running.

As a kid I thought these engines were ugly. In my fifties I see a work of art. Those 2 pins at the start would cause a lot f damage in the wrong hands (driving them through too far and protruding behind beyond the thickness of the thrust bearing). Great work mate.

[@WorkshopRebuild]

Was it because of the boxer layout or the overall appearance of BMW motorcycles? Indeed, the dowel pins that locate and secure the thrust bearings are vital components of the assembly. Both the depth at which they are tapped and their length are crucial.

This video will feature all details of this engine assembly...custom tools, torque specifications more video angles etc. I hope this will be helpful to you for the engine main bearing installation within the engine case. If you need more information about the main bearing on the opposite side, I made a separate video about that: kzbin.info/www/bejne/p6CxZn99Zq6Ye6M Thanks for tuning in and leaving a comment. Regards Andreas

A little advice from an old timer: Don't use lithium grease to assemble new or rebuilt engines, especially if the cylinders are rebored. Use petroleum jelly instead. Lithium grease grabs and holds onto the tiny pieces of metal that will be coming off the cylinder walls on break-in and any chunks of it will hold onto those microscopic pieces of iron wherever it is and cause undue wear, the rod bearings most critically. Petroleum jelly will dissolve instantly with the first oil going through and that's actually what you want. Engine oil is better than lithium grease for that matter. Lithium grease doesn't melt away as fast and can hold onto those first small pieces of iron for minutes before the temperature rises enough to melt it. Detergent is the key and lithium grease is very anti-detergent. It's why it's so good when used as a grease and not good as an engine assembly lube. We want to suspend those tiny pieces of iron and run them through the filter, not have them hanging around in the rod bearings polishing away thousands of miles worth of clearance.

[@ladamyre1]

Same thing goes for all greases: graphite and moly included. If it's "grease", you don't want to use it as an assembly lube. Greases are supposed to be anti-detergent and are made to be that way. Sticky is the main desirable attribute of a grease.

Superb !!!

[@simianwarthog]

Beautifully clean workshop. I threw a conrod on one of these on a journey, but it kept on running and got me back to town! I replaced the entire cylinder from my spare bike on the pavement outside my house.

[@WorkshopRebuild]

Thank you for your great comment! It’s actually incredible and quite amazing that nothing else seized up. In the end you were able to repair your bike and that’s what counts! Regards Andreas

Outstanding video! This was the first video of yours that I’ve seen and I am now a subscriber. Your video was clearly filmed and well paced and no unnecessary chatter, thank you very much! Your workspace is so clean and orderly and you are very methodical in your approach. This was the best video of this type I’ve seen. Looking forward to watching more of your channel! 😃

[@WorkshopRebuild]

Wow, thank you for your overly generous comment about my video! It’s much appreciated!! I tried something new for this video and I’m glad you enjoyed it. There will be more BMW related content up until the completion of the BMW R60/5 motorcycle. I hope you enjoy the rest of my videos and please let me know if you ever have any questions or concerns about my content😃👍🏼 Regards Andreas

splendide bravo tres belle mecanique beau et bon boulot !

[@WorkshopRebuild]

Thank you very much! Regards Andreas

[@simonchilli2088]

Awesome job Andreas!! You made that look as easy as a Meccano build. You didn't drop a single tool or small engine part onto the floor. If it was me that would be the order of the day as I'm clumsy. I was interested to see where the starter motor was housed as that was a problem on my R65 back in 1980. The dealer I took it to did a full service on it and charged me about £240 which was a lot of money back then. They didn't fix the starter problem tho🤗

[@WorkshopRebuild]

Thank you, Simon! It wasn’t as easy as a Meccano assembly, but with the right tools it’s a breeze. No parts nor any tools were dropped during this assembly😁 The starter is typically very accessible, as it’s beneath the started cover. Some starters had issues on the Airhead engine, because they needed to be lined up with the starter ring-gear. If they weren’t lined up correctly, the starter would get damage or in worst case scenario it would break the engine block! Oh wow, £240 is very expensive! Do you still have your R65?

[@ccoates1064]
