I need to clean out the slingers on my R69s Would it be a better idea to have it done or to do it myself. How much should it cost. How hard would it be to do myself, what would I need.

At a Minimum

You will need at least the Barrington manual, and about $500 or more in special tools, to start. Then you have to decide what all to refresh or replace when you are in there. There are all the gaskets for sure, and several bearings. Clearances on everything should be checked, you'll need the tools for that or pay to have it done. These engines are simple, and they're not. It takes a lot of study and patience to understand what is involved in a complete engine teardown. I'd say you'd have at least $1000-$1200 in doing it yourself, if you don't need any crank, cylinder or head work. Figure another several hundred to pay someone to do it all. If this will be your only rodeo, pay someone to do it.

Special tool list

Great response Dave. Is there a thread discussing about all of the tools needed for a complete tear down and assembly of a /2 engine? I haven't been able to find detailed info in the net.

Thanks

When I rebuilt the engine on

When I rebuilt the engine on my R69S. I bought the book ($100)? The all in one tool set $200, a propane torch, a hot plate. A blind hole bearing xtractor ( cam bearing stayed in the case) I wanted it out to replace. And just hand tools from my tool box. And you have the tools and book to do another time....Or bike. Cycle Works Has the tool kits/All in one tool.

R69S Slinger cleaning

Having recently finished a restoration on my R67/2 with R69S engine and still working on R69S for sidecar (engine complete)I wanted to share my thoughts.
The Barrington manual is a must have along with the "Many in one tool" that Cycle Works sells. The two engines I cleaned the slingers on needed the service. I was quite intimidated at this process since I'm a home hobby mechanic not a pro. Watching the video on DVD that outlines this procedure is quite helpful (from Cycle Works). My engines sat on a bench in the basement for two years before I did the work. I called around to see if I could have someone else do the work and was surprised at the number of real BMW mechanics that had never actually done it.
The Many in one tool worked perfectly for me, I also bought a special tool from Cycle Works that pulls the main bearings off. I replaced the piston rings, had the cylinders honed at a shop.The heads looked perfect so I took the valves out and cleaned all components and lapped valves in. I ordered a complete gasket set which you will need. I didn't replace the main bearings or the cam bearings. I pondered this decision for some time. The original bearings looked and felt fine to me so I used them again. On making this call several guys said they would absolutely replace all bearings and several told me they would reuse the originals. That call is all yours. The actually job was easier than I would have guessed, I found the Barrington manual, as wonderful as it is to sometimes get way too technically specific beyond necessity . Just my opinion on that. The R67/2 project has been finished for several months and I've ridden the bike over 800 miles. First kick starts which may helped by upgrading coil and alternator. I sent the magnetos to a shop in Maine to be remagnetized , inexpensive and something I would also recommend .I converted the electrics to 12 volts with the high output alternator from Motored Electric. (recommend).
I have a Google drive of my entire restoration included slinger work I can email if interested. Michael

With all parts/crank

With all parts/crank rebuild,etc.,look for $2k-$2500.00 even when doing it yourself. You have to pay for the new pistons,$4-$500.00,crank rebuild,$600.00,tools $400.00,boring cylinders,new bearings,coil,clutch,etc,it all adds up.

I thought

My assessment of what you would need is on the conservative side, I thought. Thomas is absolutely correct in his estimate if you do everything possible. My guess is your bike needs something in between. It is foolish to do just a slinger clean on the 'cheap', while neglecting something else that needs attention.

The factor that tipped me

The factor that tipped me towards paying someone to do the slinger clean/rebuild was that the bike will be worth quite a bit more if I ever decide to sell and can show receipts showing the work done by a pro instead of me in my garage. I know when I buy something that has been "rebuilt" by the owner I assume its a mess inside.

The labor is a relatively small part of the cost on a rebuild of these motors, once I bought the needed tools I would have saved less than $1000 doing it myself.
