BMW R35

Post by luca.stere »

Hi guys,

After this forum was updated my other topic about BMW R35 was "broken" and I can't fix it. So I will begin another one and I will ask the admin to delete that one. This was the bike:

Looks like a nice project. We are also working on an R35 at Scottie's Workshop. Big project due to the bike being in poor condition. Many sub-projects in the restoration, including crankshaft, cases, new forks, new rims, ring and pinion, 2 gearboxes into one, custom nickel plating, glasurit paint, custom seat, custom stripes, etc. Here are some pics.

I don't have any helpful information to add, but I just wanted to say that the bike Luca.stere posted is one of the coolest bikes I've ever seen! If you don't mind my asking, how much did it cost you to get that bike, which I assume you bought in it's current condition?

Hello,
I've bought an R35 in the UK. They were never imported here (rejected by the importers as gutless). My purchase turned out to be a collection of u/s parts dressed up to look like a near-complete bike (from Dutch Lion), so plenty to do. I bought an engine/gearbox from Belarus, which turned out to be a much better prospect. Still need entire final drive and many small parts, so will be going to Mannheim.
My initial engine/frame are from 1947 and the engine/gearbox from 1949. I'm not obsessed with pre-war or exact date or originality but I do want to know what I'm buying. Luca Stere has said on his youtube that, for instance, there is a lug on the crankcase above the crank to cam drive. This is on my 1949 but not 1947 engine. There are other differences, if someone can help with them. I also think I have later forks and front mudguard.
Best wishes, Charlie.

It is not my bike and I don't know the price for the bike. Initialy the bike was incomplete, the owner made an efort to make it like you see in the pictures and functionaly but it was not in a good shape. So after he succeded to make it functional and with the proper documents he decided to rebuilt the bike. That is how and why this bike arrived in my garage in order to be rebuilt. I will show later the progresses that I have already made.

Thanks Luca, also on one engine the mounting for the contact breakers is on the alternator drive cover, on the other there is a spigot from the cam chain cover passing through the alternator cover. Then the spindle that screws into the crankshaft to hold the cam chain sprocket and the alternator drive pulley, one has teeth to locate the cam drive sprocket and the pulley is located with a woodruff key, the other has a hex and the pulley is held on a taper. One engine is '47, the other '49.
Charlie.

The spindle from the right is the first model made before the war and it is threaded on the right: http://www.oldtimergarage.eu/catalog/pr ... ts_id=6497. The one on the left is the second model made after the war and is left threaded.

That means also you have also first and second model crankshafts, the puleys did not have keys on the tappered zone, is just an "improvement" because of the problems with the tappered zone.

Thanks again. Next problem is, I'd like to take the gearbox apart. There is a large bronze bush on the gearbox mainshaft, clutch side. I presume that's the first thing to remove (plus its 4 bolts). Is this an interference fit in the casting, so I have to heat the casting and tap the mainshaft from the final drive side?
