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!!
“Ran When Parked”
“Just needs gas and a tune up”
Ahhh… the phrases I am seeing in the ads when people are selling a complete hunk of crap. I bought the last restoration candidate knowing I was going to do a full rebuild but the owner’s ad and conversations were trying to sell me on the fact that the bike could run with an afternoon’s worth of work.
WRONG. I found all sorts of surprises when rebuilding that engine (and elsewhere throughout the bike).
The bike was an R75/5.
One issue was a deep in the engine when taking out the cam shaft. The lobes were severely pitted rendering the cam useless. The bike still would run but doing a complete rebuild was necessary to make this bike ‘right’. I have a stash of spare parts and happened to have an extra cam shaft lying around. Here are some photos of the bad cam. If you ever get this deep into the engine block (or at least have the cylinders off), take a look at the cam lobes. If they are pitted, the lifters probably need replacing too.
Here is a simple oil filter change fault.
If you don’t know the history of the bike, it is good to do a complete fluid change as soon as possible. When replacing the oil filter, make sure that the entire old oil filter comes out.
In this case, the gasket and end of an old oil filter were jammed into the rear of the oil filter galley. I’m assuming that an old filter got removed, those parts were left inside, and new filters were installed on top of them, thus jamming them in there even further. It took me nearly 20 minutes to devise chopstick like tools, with hooks on the end, strong enough to pull this stuff out.
Just another reason that the used motorcycle market is overpriced on 30-40 year old machines. Unless you know the bike has ZERO issues like this deep down inside, the cost of repairing these motorcycles is much too high compared to the asking prices these days ($4000 for an old Honda? why?).
In addition to the engine needing a rebuild, the steering bearings were rusted (which is dangerous), the splines and driving dog were almost gone on the final drive and rear wheel, and LOTS of other repairs were necessary. Again, I planned on doing all the repairs anyway but beware of the “Just needs a battery and a tune up” ads.
