Preventive Maintenance
RC cars have many moving parts which will wear over time. The normal wear of these parts as well as dirt from the track
and occasional crashes require you to keep your car well maintained for optimal performance. Weekly maintenance
should include:
Remove and clean wheels and tires. Check wear and glue joints.
Check for “gritty” ball bearings. Clean and re-lube or replace as needed.
Remove shocks from the car, remove springs from the shocks and check for normal movement.
With the tires and shocks removed, check suspension movement and make sure it moves freely but without too
much slop. Even a small amount of binding caused by a bent pin, dirt, etc can cause erratic handling.
Remove CVAs and check for excess slop or wear. Clean and re-lube.
If differential is not smooth, sand or replace rings and rebuild. Make sure differential is not slipping on the track.
Check for loose screws.
Check for any bent or broken parts.
To Convert to Mid-Motor
1. Remove the transmission from the car and disassemble.
2. Re-assemble the transmission with the topshaft, motor plate, and diff reversed.
3. Move the shock tower to the rear of the chassis.
4. Two (2) additional parts 2224 & 3553 are required to finish the conversion.
5. See illustration below.
