Het Patanga,

Thanks very much for the comprehensive info/tips.

I have wanted one of these since they were launched (I was 12 then), and love the bike, so I would hate to screw up the beasty!

I am changing the big end shells whilst I am there, even though no excessive movement (seems to be the conventional wisdom on ADV). Any tips on this?

Where are you in Qld? I come up occasionally, and would love to stop by with a refreshment to say thanks.

Very grateful,

Toby

No worries 'Freeagain'... I wish you success with the build and many happy k's from there. Got your PM so we might catch up when you come to sunny Qld.......... Quick question for you... Got any tips on who's going to win the 'Origin' game tonight?

I think patanga's advise has a big no no in it. Heating up the crank sprocket till if changes colors is softening the sprocket's temper! That sprocket wears enough as they come! Personally, I am very careful not to change the color of even the very tips of the sprocket teeth for the same reason. If I do, I get a new sprocket. It's very easy to do too heating them up with flame!

Installing the master link? Use the old master link to hold the chain together and push it out with the new master link. That is the best way to deal with that issue IMO.

The most finicky part of the timing chain for me was getting the master link in from the rear of the chain. I had not done this before and I think I took at least an hour of attempts before I thought of this. I took a bit of wire - a straightened paper clip - and super glued one end of it with a tiny drop of glue to the back side of the master link. I bent the wire to the right angle and slipped it in place as easy as pie. After the link was secured a twist of the wire and the glue broke free.

I hope it is as easy for you now.

You're totally correct there supershaft. What you are looking at in the pictures is an old gear and set up for the purposes of the photo guide. In heating them for removal I'm less concerned as they aren't going to be reused. I'm very careful not to over cook them pre fitment. Can't hurt to say it again though... Don't heat the sprocket or bearing too much....

+1 You can easily mess up roller bearings heating them with flame. One race expands more than the other and it dents the races/flattens the balls. That's what they make bearing heaters for. I wish they weren't so expensive!

Right again.. The cost of bearing heaters is crazy money but obviously the ideal. I prefer to use the hot air gun on the roller bearing than a flame. Still not the ideal I know, but less risk of damage with hot air is my theory.

The cheap way to heat them up evenly is in a can full of old motor oil on a hotplate on low. Get it nice and hot and dunk the bearing in there for a bit. A heat gun makes less of a mess though.

supershaft · 06-13-2012, 09:58 PM

Or your handy shop toaster oven. That's the best way IMO. (Minus a bearing heater.)
