Setup and Adjustment Notes

The 3RACING CRA-115 adaptor is intended to give precise spur gear positioning on Crawler Ex Real chassis, helping builders achieve repeatable mesh settings during tuning sessions. Its straightforward interface makes it practical for setup changes between runs.

Compatibility and Tuning

Designed for the Crawler Ex Real series, the CRA-115 accepts common spur diameters used in competitive and club-level setups. Use it to fine tune gear engagement when testing different pinion and spur combinations to balance torque load and clearance.

How should I set backlash with the CRA-115 installed?

Set a minimal amount of backlash recommended for your gear pair and verify smooth rotation under load; small adjustments to shims or pinion position will refine engagement.

Are there recommended inspection intervals?

Inspect the adaptor and fasteners after initial test runs and again after extended use; check for any play or wear that could affect mesh consistency.

Can this part assist with fine tuning on the track?

Yes, it provides a stable mounting point that makes iterative changes to spur or pinion simpler and more repeatable when optimising performance for specific courses.
