Spline Lube, Carb rebuild and rear bearings.

Julio,

I have ample 0.05mm shims and a variety of different sized wedding bands for the 17mm diameter axles I'm happy to send out to you if you have any problems obtaining them.  It's your call, just let me know.

Any of you interested in the pull test procedure of preload determination...I've attached a PDF copy I've created for my own use in my previous post.  You are welcome to it and give it a try.  I used the pull test procedure for numerous bearing jobs to determine the correct feel for proper preload.  It's a valuable procedure in my opinion and gives an eye-opening hands-on account of the tolerances involved and what a huge affect 0.05mm (0.002") can have on the bearing operation and preload determination.

I had three wedding bands machined from steel with widths 6.5mm, 7.0mm and 7.5 mm each.

Mike took me step-by step on the proper procedure to get the wedding band with the proper preload. It took me 30 minutes to remove the rear wheel, replace the race, clean and lightly oil everything. I did the shake the wheel test and ended up with the 7.0mm wedding band and at least 40 figure-8 laps around a 360 grit sandpaper.

With my new wedding band already in place, I increase the axle nut torque by 5Nm(as my torque wrench only ready Nm), any wheel wobble went away at around 25Nm, as I further torqued it to 30Nm(around 23Ft/lb), the wheel resistance did not change as confirmed by a pull scale.

I swear, this wedding band was quite easy when you get the preload stuff all sorted out in your head.

As for the Final drive temperature.... I will get back on that, after today's ride, somebody(   ) "accidentally" pulled the drum too much, causing it to drag all the way.
