1/10 Scale working 5 speed transmission for 1/10 22RE motor

thingiverse

Update: After checking the scale it's actually close to 1/10 scale, maybe a bit larger. This is a remix of Ericthepoolboy's working 5-speed transmission for the 22RE motor. I resized the files to 1/10 scale to work with my resized 1/10 22RE Toyota motor. Many of the files were changed to accommodate the new hardware. All the hardware used was the same as the 1/10 scale 22RE motor. Almost all parts were printed at .1 resolution. This project will test your printer, modeling skills, and patience. It was fun. Some of the changes are: No washers are used. Bearings used were 5x2x2.5mm (MR52zz) acquired from Banggood.com The shift collar gear no longer uses set screws. You must assemble the transmission and note the location of the collar gear, then glue it in place. Gear 1 top also glues into place on the input shaft. If you can source small set screws, suggest using a set screw. The shift collar gear 5th also glues in place. Shift forks and collar forks also glue in place after assembly. Top Rail is gears 1-2 collar fork, bottom rail is gears 3-4 collar fork. See the picture for instructions. Depending on the rod used, you will have to clear holes. I used 1.5mm and 2mm carbon fiber rods. Shift collars outside surface that contacts shift forks need to be sanded to a smooth finish. You will have to clear the inside so it slides on the collar gears easily. I lubricated all collars and transmission gears with gun grease. If you're going to use my spur gear from the 22RE motor build, you'll have to shave the bell housing a lot where the pinion goes in or it will rub the bell housing and stop the motor from turning. https://youtu.be/x5OagnD-HUs This is not an easy build. Due to the small size and printer variances, you may have to sand, file, or ream parts for fitment. Entire project can be printed and assembled in 2 days.
