LOVE THE BEER CAN TRICK...NICE VIBE, MAN !..Thanks

[@joewilson2002]

I am trying to restore my fathers 1975 BMW r90s. My father passed away a few months ago so I'm more determined then ever. The bike sat outside, under a rotting tarp for 35 years and I'm doing a frame up restoration. William is great at showing me how to do different things that under normal circumstances, even with a Clymer manuel, I wouldn't attempt to do. I wish I had Williams patients and his tool's!.

[@boxer2valve]

Hey Joe, Best of luck with your project! Your father would be so proud, I know!

[@joewilson2002]

@@boxer2valve Thanks again!

[@mikegover1260]

Always a pleasure to watch you work your explanations are clear and precise. I like the use of the correct tools to carry out the tasks. Please keep them coming I would like to see more of your work on the older BMWs.

[@CaskStrength777]

I'm taking my engine apart final drive transmission everything right now for the first time. I can't tell you how much this helps on top of the Blue book and the clymer manual with flatracer tools 👏👏👏 The pop can solution to that was genius. You're doing God's work man thank you 🎉 I have this exact make and model early 75.

[@fostermckeon9504]

absolutely loved the soda can trick! So entertaining watching and listen to you work. I have a 90/6 '74 that needs to be getting back on the road. You inspire me.

[@ramsayward6582]

Brilliant channel. Thanks for posting these videos. They've been invaluable on my project.

[@duncandorris884]

Extremely helpful - I used this to reseal my R100/7. Thanks so much for the excellent explanation!

[@boxer2valve]

Great to hear !

[@joewilson2002]

By the way, I called Boxer 2 valve a year or two ago with some questions. A week or two later, I got a call from William. He was in Germany but because he is such a nice and dedicated man, he called from Germany to answer my questions.

[@boxer2valve]

Hey Joe, Thanks for the comment. We will help whenever possible. Doesn't matter where we are. Cheers!

also...this series of BMW videos is so helpful. thanks for making them!

[@edwinthompson159]

so plain, so clear... as you go along I have googled the tools -- amazing how reasonably priced needed tools can be bought -- lov the old school thinking of using a soda can -- great videos.

[@boxer2valve]

Great to hear!

[@thierryroullier8401]

At this point in the set of videos I know this read drive seal replacement task is beyond my skill and tool sets. This video will be a great guide to be prepared for a Tech day. Thank you for doing this.

Thanks for you input. Some procedures are more difficult than others. There is lots more to come so please be sure to subscribe!

[@jimkelleher4101]

Mine too Thierry - wonder what a BMW shop charges for this?

[@chromzwoodruff7325]

All the special tools together probably out value a decent condition complete air head. One large part of being a mechanic for many makes is the ability to improvise.

[@andrewsnyder2087]

love the soda can trick!

Hi Andrew, I was equally stoked to figure that one out! Thinking outside of the can!

Exactly what I need... thank you so much...

Great video. Noticed my 1980 r80 started leaking oil out of one of the pin hole drains so I'm going to change the seals.

[@leafygreens7318]

Hi William, Excellent videos with clear and concise explanations and great detail camera angles. I enjoy your use of mixing proper and shop made tools to get the job done, and of course your knowledge and use of tricks and tips. Quick question for you or your viewers; I have a 1995 r100 GSPD, and found oil dripping from the final drive. Not much but enough to get my attention. I took the rear wheel off, exposing the final drive seal, which did show a small leak. The seal was sitting proud about 1mm or less. I thought if the seal was not installed properly it could leak so I tapped it in a little bit more about another 1.5 mm. The question is, was it sitting properly and just a bad seal needing replacement or did I tap a bad seal in to far? Thanks again. Petr

[@garrysmith5024]

Another great video.

[@JM-sb4nb]

Excellent

[@ziaride]

Great video! Mine is getting fluid transfer from the drive shaft to final drive and needs this done. After watching this I think I'll pay someone to do it ;)

[@boxer2valve]

Look us up in North Carolina. We would love to help you out!

[@snake_hole2886]

maybe it wasnt allowed, but i posted that performance tool w1270 will work fine to get the slotted nut off the output shaft if you cut off 4 of the ears and its 10 bucks if you do a quick search

[@rotory2002]

Even the Dog was excited ! :)

[@leeprice7706]

i am working on a 1966 R60/2 .DO you have videos to halpe me?The Re-sealing the final drive is a big helpe.

[@clarkmorris3312]

I noticed that you use a heat gun to expand the rear drive to remove and put the bearing back in. Is there a particular reason you use a heat gun.... and not say a Map Gas torch? Would not a Map gas torch get the job done faster? Or do you use the heat gun to keep from using too much heat? Just curious.

[@boxer2valve]

We use the heat gun because it applies an even and relatively low heat. We don't want to exceed 100C. Also I have not tried a MAPP torch, so that might be better yet.

[@MatiasCorea]

Torches are very agressive and can warp things. Also they can melt and deform the seals. Faster is not always better. I was taught only with a heat gun, also you could say it's safer and you're not taking that much longer...

[@antoniomarzoanotlevsen5343]

I am re-watching your videos, and it has been nice to hear you when saying“PERFECTO”!!. I am Spanish (&50% Danish), that’s it! (MOTOWERKE at Instagram).

[@boxer2valve]

That's awesome!

[@edwardj456]

Is there any difference in procedure for the 1979-1984 R100RS/RT bikes? Great videos, bing watching :) Thanks

[@MiteyMOofyearsAgo]

Love these Videos! I have these tools that I bought at dealer auction back in the 80's. I never knew what they fit. I have a rear end (37/11)from a '74 r60/6. (my 1st Beemer). Splines are 40%. Can you give me an Idea what a rebuilt drive would fetch and the cost of parts. I can do the disassembly and reassembly. Thank you again

[@classiccycleconnection9334]

Q: is it possible to only replace the ring gear seals and gasket (not the piñon seal) while the final drive is still in the bike or must it be removed ? Thank you for all the great info !

[@jezwatson8211]

Great video, I’ve just bought a 1985 R65, is the final drive the same? And does it have the same weep holes? Thanks, Jez.

[@boxer2valve]

Hi, the 1985 final drive is entirely different. It does not have weep holes. We will actually be taking one apart pretty soon. Check out our new series of videos about the R80RT. The final drive repair will be uploaded late October or early November 2019.

[@clarkmorris3312]

I see you are using an electric heat gun..... Is there a reason you are NOT using say a MAPP gas torch? Would this not heat the metal up faster (allowing the outside to expand quicker than the heat could get to the inside)... and let the bearings fall out faster? OR do you not do this for a reason? Not complaining ... just wondering from your experience...

[@boxer2valve]

We use the heat gun because it applies an even and relatively low heat. We don't want to exceed 100C. Also I have not tried a MAPP torch, so that might be better yet.

[@AuliaRahmanAR]

can someone help mention the size of the large oil seal? having difficulties in finding one. thx

[@KapteeniMahtava]

Q: What is the torque spec for the output shaft cover?

[@KapteeniMahtava]

@@DummiesGarage I think I torqued them to 20Nm or 10Nm? Haven't leaked yet..

[@johnboy515]

Excellent video William, thanks from across the pond. I've lost count on how many times I have viewed and reviewed. I'm just about to re-assemble and have found some lateral movement in the drive shaft pinion bearing (33121230247) on my 82 R100. Any tips on how I can removereplace it?
