Properly Adjusting the Slipper Clutch

Adjusting the slipper clutch is crucial to performance and reduced drive train failure. If the slipper clutch is set too tight, you stand a greater risk of tearing up your spur and transmission gears. If the slipper is set too loose, your acceleration will be softer than you'd like due to the slipper spinning excessively.

The slipper setup of the Revo is very different from earlier Traxxas models, and does not suffer from the "melted spur syndrome" that could occur when the slipper was set too loose. So while you'll want to set your slipper as tight as the circumstances dictate, you shouldn't be afraid of leaving the slipper a little loose as a safety cushion when needed.

Since the slipper clutch for the Revo is different from most other Traxxas models, the procedure for adjustment is different as well. You'll want to use a 2.0m hex driver to hold the slipper clutch's shaft in place on the opposite side of the transmission from the slipper clutch. Then tighten the slipper clutch nut down with an 8mm open end wrench. A good starting point for the slipper is to tighten it down to where you can slowly turn the spur gear by hand while holding the slipper shaft with the hex driver. From that point adjust the slipper clutch tension as needed.

It's important to note that you should never lock the slipper clutch on the Revo as a starting point, or anytime for that matter. Doing so can permanently damage the slipper components as well as cause frequent replacement of the spur and transmission gears.

As a side note, the Revo's spur gear can be swapped out without altering the slipper clutch setting. Once you remove the three screws surrounding the slipper nut, simply pull the spur off and replace it. This is a big advantage to the slipper clutch setup found on the Revo.
