The United States Lawn Mower Racing Association is on the cutting edge of racing tech and driving strategy and advice! In this ongoing feature, “Tech and Driving Advice”, some of our fastest drivers and most knowledgeable gear-heads will share with you their mower racing secrets!
This slide show, by USLMRA Vice President Kerry Evans, shows the process of converting a Peerless 820-022 to a 820-017 racing transaxle.
Here are the steps detailed in each photo:
- Shows the 820-022 transaxle and location of the unit ID Plate.
- The transaxle with the top cover removed and the parts that will be used to up-grade to and convert to a 820-017.
- Shown are the gears that are removed that will be changed.
- Gears that will be reinstalled for the upgrade.
- Rear Axle to change out from a Differential to a Straight Axle.
- All gears are in-place for alignment… final setup!
It should be noted that the 820-022 has a ratio of around 12:1 and the 820-017 has around a 4.2:1 High Gear “Final Ratio”. This setup will allow you to use smaller pulleys in the front and close to a 1:1 pulley drive in the back. Remember to install your detent ball & spring in the set screw hole after the top cover is in place, and fill with your favorite gear oil!
