Re: AndyMark Nano Break In

Just a quick update on two observations after receiving our NANOs over the weekend.

First, we used a 5/8" retaining ring to fill the "wiggle" on the last stage output shaft. It slipped right over the hex shaft and was the perfect thickness to reduce the wiggle but still be free of binding.

Second, we noticed that there is also a little slop in the first 50 tooth input gear that the CIM pinion mates with. This was causing the gear to contact the two washers on the CIM shaft for positioning the pinion. This caused significant binding and may be the cause of the high current draw that some people have observed. The solution was to assemble the CIM pinion with only one washer behind it.

After assembly we ran in for 15 minutes and the gearbox was humming along with the CIM only drawing 2.4 amps!

We are direct driving our kicker off of the NANO and have made many kicks so far with no signs of wear or tear. The thing works beautifully!
