Chain Care


MicroBlue Chain Care

NEVER immerse chains in any hydrocarbon based or water based solvents. When this happens, the net result is you wind up washing the lubricant out and washing dirt particles into the pins and bushings. This will inevitably remove the coating and cause pin seizure. Instead, use compressed air to remove any dirt build-up in and around the side plates. This is the dirt you see, what you care about is what’s going on inside the pins and bushings. These rarely have dirt in them.

NEVER use any pourable oil, Tri-Flow, WD-40 or any other spray penetrates. There’s two problems with those. First they’re not thick enough. Remember one, the only thing holding two surfaces apart is viscosity and two, lower viscosity with contact is always much more drag than higher viscosity with no contact. Think about this: The effective width of the pin is between 1/4 and 3/8’s inch. And the contact width is maybe 1/16th inch. The same goes for the bushing bore.

Now typically the load is carried by 2 1/2 to 3 chain links. So do the math. What is the total square inches here that represent the bearing area? Not much, very little in fact. Now do you think for one minute that any of the above lubricants have anywhere near enough viscosity to keep that pin from grinding into the bushing? Absolutely not.

The one thing we have seen for years is people going too far in the “too thin” zone when it comes to chain lubes. Sure it may roll free on the stand, but what about under acceleration coming out of a corner? If there’s one place where you need “no contact”, that’s the place. Even for low horsepower applications such as karts and quarter midgets, the “thinnest” lube should be the equivalent to a motorcycle “O-ring” chain lube. Why is that? Because it comes out alcohol thin, but tacks off to a very nice thin grease thickness that keeps those pins and bushings from making contact.

Because of this, we recommend the use of PJ-1 O-Ring Lubricant (Blue Label) for karts, quarter midgets and Bandoleros, etc. You’re not limited to PJ-1, any motorcycle o-ring lube will be sufficient. Good luck and be fast!
