1983 BMW R100RS Install Push Rod Tubes & Head Studs

[@lorettam8924]

As a warning for others, I just did this job with same push-rod tubes into Siebenrock cylinders. The collars are positioned by a machined shoulder on the tube. On 2 of them the collars moved away from the shoulders, and as result after I thought I was done, the tubes had been over driven and I had to revisit the job. The collars are just press fit and either the cold shrinking or the whacking with the hammer moved them. As you do the installation you have to move your head and look under the collar to make sure the collars remain in place against the shoulder. Thanks Brook I enjoy visiting your site.

Thanks Brook, I've been watching all of the RS videos for maintenance on my 1983 RT. It is very helpful to see the work being done live.

Jason, I hope the rebuilds and documentation I published on my web site (www.brook.reams.me) over the past 12 years can help you keep your RT on the road for many years to come.

Thanks for another great video! Always look forward to them. it's nice that you explain what tools you use and where you get them. You are a very busy guy!

Hi Mike, As a retired old fart, I do have time to devote to this work. And, it keeps me out of the bars ... well, most of the time. :-)

[@johnashcraft2724]

This makes much more sense now. Great video! Keep ‘em coming please.

[@BrooksAirheadGarage]

John, Cool beans. Maybe you can get another airhead. I know a guy who has a couple :-)

[@vespasandengines]

This video and the tips contained saved my build... can’t thank you enough...!

[@BrooksAirheadGarage]

Hi Andey, Cool Beans. It's satisfying when my mistakes can help others avoid them. :-)

[@assessor1276]

Interesting! In theory, very simple but lots of details to keep track of....

[@BrooksAirheadGarage]

Hi Peter, Indeed, "It's easy when you know how." :-)

[@malcolmnash5850]

Brilliant once again, so straight forward and easy to follow.

[@TheRv1890]

Excellent videos! Keep them coming. I look forward to each one.

[@BrooksAirheadGarage]

Silver Fox, well, there certainly is a lot more work to be done before I get to ride this project for the first time.

[@pjpankras]

Great tip with the paper towel trick!

[@BrooksAirheadGarage]

Peter, It works well to keep that end of the tube cold while driving it in.

[@pjpankras]

@@BrooksAirheadGarage Thanx! I will do it the way you showed. Love your channel, really valuable information!

[@bradyspage]

Holy shit that is A LOT of loctite! All you need is one line of it down the threads. When you run the stud in the loctite will be dragged across the entire threaded surface

[@jeroendevl7825]

Thank you for your video’s they are very helpfully! Keep It up 😊!

[@BrooksAirheadGarage]

You're welcome Jeroen. Thanks for stopping by.

[@jordananastasov309]

Thank you.

[@BrooksAirheadGarage]

You’re welcome Jordan.

Great video! Can you drive out old push rod tubes and replace with the stainless steel ones? And is the measurement of 1.8-1.9mm the same for a 75/6?

[@BrooksAirheadGarage]

Hi Andey, I show doing that work here: kzbin.info/www/bejne/oZSwlnmVidKDotk The cylinders, push rod tubes and push rod tube seals changed in 1976 when the 99 mm cylinder sleeve was introduced in preparation for the 1000cc motor introduced in 1977. That said, I've been told by Tom Cutter that the 1.8-2.0 mm clearance is a good distance for all the airhead push rod tubes. Best. Brook.

When water freezes it expands. Feels contradictory with the shrinking of the pipe. It's only a thin-walled pipe so I wonder who wins: the ice or the metal.

[@BrooksAirheadGarage]

Koen, the metal wins and the water extends out the ends.

[@rustynuts82]

I’ve done this job twice, both times the seals split! I can see why now. I have noticed that the old seals are a different shape to the newer version.

[@BrooksAirheadGarage]

Bikers Welcome: I'm glad this is helpful. IIRC, the seal shape changed when the 99 mm cylinder bores were introduced in 1976 to support the 1977 1000cc motors. So you have to select the seal shape for your cylinders.
