crank mods
Danger4u2:
Shot peening really works. The parts you see are change over subs, it's used for changing from one thread type to another. The parts you see are used for boring holes under the road bed of streets and highways for the gas and electric companies. These parts without shot peening break off the pin end from fatigue cracks after about 2 months of use. With shot peening they rarely fatigue crack, and use shoots up to 9 month to a year.
With the naked eye all you can see is the shine has been removed. With a 30x lenses you can see small dents in the metal. We do a 150% to 200% blast coverage to make sure the whole area is covered. And yes I have done connection rods and cam shafts for friends ( on weekends, off the clock, with the boss's permission ). The part on the left has been peened.

I have not had the cases open on a kx500 engine. Is there any area of the crank case that can be stuffed :?:
