Frame grinding and the tool of awesomeness!

| January 9, 2012 | 0 Comments

I ground off the left over air breather hanger and finally started sanding (sounds weird when it comes to metal) the frame to remove the left over welds.  I’m using a Ryobi hand held grinder that rotates at the handle in 90 degree increments.  Thing is bad ass! I think it turned out pretty good for my first time using a hand grinder –

Removing the steering shaft has been a pain in the ass.  What the Clymer manual calls for is a ‘Pin Spanner’ to be used on these nasty adjusting nuts.  I don’t have any of the original tools, and from what I read they were crappy anyway, but this spanner seems to be a rather unique tool –

Not only have most established motorcycle dealership parts departments I’ve visited looked at me like I didn’t know what I was talking about, but even on-line no one seemed to know where I could get one.  The most common response was “just use a screw driver and hammer to pop it off”.  Well, tried it, and the damn thing didn’t budge an inch. Plus, for reassembly, you need to apply a specific amount of torque to both adjusting nuts, so an adequate tool is necessary.

I did find an adjustable ‘Pin Spanner Wrench’ at the Yamaha Sports Plaza website, but it is backordered until February.

Fortunately I found a small local motorcycle/atv repair shop finally that not only knew what I was talking about, but also let me rent their tool over the weekend for a security deposit –

Pin Spanner Wrench - the tool of awesomeness

Learning from my previous experience, I WD40’d the shit out of it first and let sit for about 5 min.  Then, wacking the wrench with a rubber mallet I was able to finally remove both upper and lower nuts.

With steering shaft removed I looked over the bearing races and they’re both rusted and gouged.  Looks like I be replacing both bearings and races.

Although I continue to make progress on this bike, at times it feels a bit overwhelming. I am enjoying the process, and I’ve got plenty of time before riding season starts.  I guess like anything, the first time is always the hardest.

Next up is tearing down the wheels and preparing them for sand blasting and powder coating. I’ve decided that any bearings I come across will get replaced.
