I also need to put a new radiator and electric fans in the 1958 Station Wagon, and do a few things to the 1976 Motorhome to get it ready to sell… And I work 6 day weeks til mid april.

So….. Not likely I will be “done” when the weather gets warm, but I will be CLOSER!

Das Bike Project: Pulling Down the Final Drive

As you may remember fluid is moving from the Driveshaft Tube into the Final drive, bad news as this fluid overfills the final drive and then gunks up the brake shoes.

So today we pull the final drive apart to replace the seals and check the gear wear!

The captions tell the story.

Das Bike Projekt: Oil Pump Cover and Flywheel Re-Install

As you MAy remember I had to use rather destructive means to remove the oil pump cover, and had to order newer parts that had proper bolts. This has held up my putting the Flywheel and Clutch back together, well, no longer! MAXBMW has sent me the parts, and on they go! Click to enlarge….

Das Bike Projekt: Trans Input Shaft Seal

I found a cheap trans, but the input shaft seal area looks about as gunky as mine, so I am going to replace the seal as long as I am in there. The old one it very hard and brittle. An easy fix while I have things apart. I replaced the throwout bearing and seals while i was in there, too. And moved over my /2 kick lever and shifter.

Das Bike Projekt: Yank My Flywheel!

Next step is pulling the flywheel to replace the rear crank main seal, and the oil pump seal.

Todd helped me fab up a flywheel stop, and puller adapter, and also helped when the old style phillips head oil pump cover screws refused to budge and we had to resort to heat and cutting. Good news is it all got done, bad news is it took all day, and i will have to order a few more parts! Click photos below to enlarge.

Next time: Transmission clean-up


Das Bike Projekt: Motorbike Archeology

Just a quick post about some markings that I found stamped into the engine block, just below the flywheel.

As you may remember this engine has the Big Bore kit in it, well the previous owner punched the specs into the engine block, where they can only be seen once the transmission was pulled!

Das Bike Projekt: How to Build a Better Clutch

So from our previous entry, we saw that the stock R75/5 clutch components were not up to the power of the hopped up, high compression, hot cammed Reg Pridmore engine.

How to get a clutch designed to deal with more grunt? Not as hard as one might think.

The stock 1973 engine put out 50HP and 44 ft lb of Torque. But using the same block, in 1973 to 1976 BMW built the sporty R90S with 67HP and 56 ft lb of Torque. After doing some research, I found that BMW designed a heavy duty clutch, which is still available for the R90s and later bikes, and that it would all fit on my bike, without modifications. Below are comparison pictures of the old and new parts, click to enlarge…

Das Bike Projekt: Inspecting the Clutch

Pulled the transmission to get at the clutch, found lots of gunk in the bellhousing, something is leaking, and once the clutch was apart we can see that, yes indeed, it has been “slipping a bit” kind of a BIG bit, actually. Click on photos below to enlarge!

Das Bike Projekt: Inspecting the Final Drive.

Well the deeper we get, the more we learn, right? SO, In a nutshell we have fluid leaking from the driveshaft tube into the final frive, then out of the final drive into the brake drum and onto the brake shoes. So I will buy the tools to blow apart the drive and replace some seals. Also we have an alignment issue. Remember that the earlier /2 bikes, and the later /5 bikes have very different frames. The motor looks like a bolt in, but it isnt. one issue we have is that the driveshaft is too short, so you either have to insert a spacer, or use the shaft from a later bike. I remember asking which method he used. I think i remember him saying he replaced the shaft. He did not. The input drive gear is heavily worn JUST on the front 1/3rd of the gear. So thats 2 more expensive parts i need to order, the gear, and the spacer.
