Replacing the Throttle Bellcrank Bushings

The Revo comes stock with plastic bushings installed in the throttle bellcrank. At first these are fine, but over time they will wear and need replacement. Instead of using the stock plastic bushing as a replacement, you can use 5x8 bearings. You'll need 2 5x8 bearings such as these offered by Traxxas. Not only will this eliminate having to replace a worn bushing later, but you will be rewarded with a throttle bellcrank that operates much more smoothly.

All you need to do is to remove the throttle bellcrank from the Revo's motor mount. A single screw holds it in place. Once the screw is removed, pull it loose from the motor's carburetor. It's not necessary to fully remove it as I have shown in the pictures below, as that was done for purposes of clarity.

This picture shows the stock bellcrank with its plastic bushings.

In this picture the bushings have been swapped for 5x8 bearings. Keep in mind that there are two bearings that need to be replaced. You'll find one on each side of the bellcrank.

Once the bushings have been replaced with bearings, reinstall the top portion of the bellcrank, followed by the screw. Make sure you don't overtighten the screw, as it can cause the assembly to bind.
