U-Trak Noise

--- Quote from: Wikipedia --- * 50%: Stoddard solvent (i.e., mineral spirits -- primarily hexane, somewhat similar to kerosene)
* 25%: Liquified petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
* 15+%: Mineral oil (light lubricating oil)
* 10-%: Inert ingredients

* WD-40 is not contact cleaner. It leaves a sticky residue that can attract dust.
* WD-40 should never be used in locks for the same reason. Locks should be cleaned with isopropyl alcohol, allowed to dry thoroughly and lubricated with dry graphite powder.
* A sample of WD-40 that was sprayed onto a piece of steel plate and left outside at -25 for about 20 minutes froze.

This is why you can't use it on skateboard bearings. The solvent removes the real grease used in the bearings and just leaves the "light lubricating oil" which actually attracts dirt (from what I've heard.)

Tri-flow is an excellent lube and offers great chain protection but it does pick up a little more dust than others... on the other hand the teflon and ptfe additives makes removing that crud much easier as it just can't stick.
I get 3500-4500 km per chain and apply lube very sparingly... I use one drop per link and then I listen to Boheniam Rhapsody while I wipe the excess down with a rag.
:)
WD40 is better than nothing but it isn't a good chain lubricant... if you think this question gets asked here a lot come and work in our shop.
I should actually promote the use of Wd40 as then we'd sell even more new chains...especially in the winter months as it offers virtually no protection when things get ugly.

It seems that people have a lot of differing opinions on the use of WD-40...however bike chains and skateboard bearings are a lot different than a trackball...

WD40 should be fine. Its just a light oil with other stuff added, which evaporates leaving the oil:

But there might be some reason for the noise. One possibility is a small lump of dirt stuck to the roller at the point it contacts the ball. There is no problem with running smooth emery paper against the roller and spinning it, to eliminate anything stuck. The roller itself is unlikely to be damaged as its hard stainless-steel.

How do I access all this to lube it?
AndyWarne:
There are 4 screws recessed in to the base. Just remove these and the top lifts off, and then the ball can be lifted out.
Another thing you can try is swap over the rollers and/or bearings and if one bearing is noisy we can send a replacement.

Visitor Q:
From the top you say? Hmmm... Well that could be a problem. I don't think I have access to the top of my CP in that way.
I am not sure how I would be able to get to the top of the U-Trak when it is flush mounted. Guess I really need to take a closer look at it.
Ginsu Victim:
remove it from the CP and you can open it
