Re: Kit Transmission
 

I designed the gearbox with the spacer, because I do not like set set screws. The spacer, combined with the screw and washer at the end of the shaft, positively locates the gearbox in the correct spot. When I did prototyping last year, I used PVC tube for the spacer and it worked fine.

The manual, located at the IFI website, describes all of this in detail and provides a drawing for the spacer. I have attached my original drawing for the spacer in this E-mail.

Re: Kit Transmission
 

My team has found a problem with the kit transmissions. They followed the directions for the standard one-CIM configuration, but upon further testing, we realized that the spring washer was rubbing against one of the gears. Has anyone else had this problem? We are planning on removing the spring washer, and just putting loctite on the set screw.

Some spring washers come in oversized and will cause this problem. Use the alternate assembly method using the setscrew with Loctite on the set screw and you will be fine.
