I can’t remember the condition of this final drive when I assembled my 77 R100s back in 2003. When I had my rear tire replaced recently, I noticed how terrible the splines are. The splines on the wheel are better then the final drive but they will need replacing someday too.
I found this drive with the same ratio and cleaned it up and replaced the spline. Now it is time to swap the drives.
While it is apart, I am taking the opportunity to pull the tranny back and lube the clutch splines as well.
Back to Beemers…
I’m working on a project bike for a friend and had the items powder coated satin black. I’m very excited to see how this bike will turn out.
And yes, I have a very messy garage/workbench at the moment.
I removed the wheel bearings and the races with lots of heat, and the help of a press.
Then went to the powder coat shop and gave them the masking instructions.
Here are some photos of the install.
Not pictured is the process of checking and testing the bearings in the race to make sure they spin smoothly.
If not, clean them, re-test, and clean them again, etc…
Then grease ’em good!
Also not pictured is the process of cleaning the inside of the hub REALLY well. Especially since they were sand blasted.
And.. then there is the process of pre-loading the bearings, freezing them for a day, heating the hub and then ‘plop’, you are done.
The manual available for this bike is old, with terrible photos. So I am snapping shots of everything while I take it apart. How would this happen in the film days??? Expensively I guess…
Pixels are cheap.
More Photos to come…
I have no idea what draws us to certain bikes… but I saw this for sale, cheap, and I had to get it. I think the toaster tank had something to do with it. It is a 1967 Bridgestone 175 Hurricane Scrambler.
I’m waiting for a bunch of custom BMW parts (in development), that this seemed like a good place to put that antsy restoration energy.
Supposedly, Bridgestone made such great bikes that they were pressured by other Japanese motorcycle companies to stop making motorcycles, otherwise the other companies would stop buying the Bridgestone tires.
This bike arrived a bit rougher then I expected. With some help of a mechanic genius at the Oshmo shop, we got it running.
It had a weak spark so I waited about a month for some parts to arrive, replaced the coils and with the help of my daughter, we got it fired up with one kick.
I have no idea why I am going to sink time and money into this bike… but she is going to get torn down for a complete restoration with some custom bits thrown in.
Stay tuned for some 2 stroke updates…
Just an update… I have 3 bikes in the works but they have been taking longer then expected. I’m trying to customize many features vs buying the available parts out there.
And, I’ve been busy over at Oshmo.com helping to develop some Airhead aftermarket parts that look good, and function, for customizing these old BMW’s.
Recent additions are rear sets, and top clamps… more ideas to come!!
