Greetings friends,
This is a continuation of my series of posts documenting the restoration of my BMW R65. For the previous post, click here.
When we last left off, I had removed the front wheel and was finding a solution for the damaged forks. I took the wheel to The Wheel Master, having heard that if there was anyone who could fix it, it'd be him. To make a long story short, the dent in the rim was too great, resulting in severe cracking when he tried to bang it out..... so that meant I had to hit eBay for a replacement. I looked for an exact copy, since the distinctive "snowflake" pattern of these wheels is quite unique and I wanted to keep them matching. For the forks, I just bought a reasonably priced replacement which simply bolted right on. Not much choice here, since the existing forks were just too bent up to be useful. However, removing the old forks turned out to be a bit of a chore! Here's what went down..
Handlebars off, top yoke ready to remove.
I first tried loosening the yoke clamps to pull out the fork tubes, but they must have been jammed in place because they simply wouldn't budge. I decided I had to remove the bottom yoke and forks in one piece. First off, the handlebars had to come off, followed by the top yoke. Once the yoke was removed, I could pull out the bearings and remove the entire lower fork assembly. Let's have a look at them:
Now that's a lot of damage!*
With the forks off, I removed the bearings and thoroughly cleaned them with engine de-greaser. The old grease was profoundly oxidized and no longer provided any lubricating properties, so naturally it had to go. The old forks were pretty useless at this point and since they were stuck in the lower yoke, I just cut the yoke off and saved the forks in case I needed any spare parts down the road.
Beautifully clean bearing!
Since a lot of effort was saved by buying new forks, I was able to move directly ahead to installing them after I painted the frame. I used Green Grease at the recommendation of my mechanic; the water resistance that it provides is ideal in this application. Though I don't plan to take the bike out in the rain, I still want to make sure that all bearings are waterproof.
Greased up, the bearings went into the steering column followed by the forks. Surprisingly, it was all very easy to install and works like a charm! The forks themselves have some gunk on them and will need to be cleaned more later on, but for now they're totally functional.
Moving on to the swingarm, there's actually not a whole lot I had to do. I removed the wheel (since it needed a new tire) and removed it from the final drive assembly simply to replace the gasket connecting the two. The swingarm attaches to the frame using two pivot bolts, and these are held in place with large nuts. The shock absorbers then attach the swingarm to the subframe, comprising the rear suspension.
The whole rear suspension/swingarm disassembly process.
Sort of a poor picture, but this somewhat illustrates
how the swingarm attaches to the main frame.
This all came together pretty effortlessly, so aside from both wheels still needing new tires, the front and rear suspension are both complete!
Thanks for reading,
Juju
