This Yokomo SG-6492 spur is crafted to 64 pitch tolerances and features 92 teeth for dependable engagement in RC transmissions. It must be used with 64 pitch pinions to ensure accurate tooth mating.
Proper installation emphasises correct mesh and backlash: set the spur and pinion so the load is distributed evenly across each tooth, avoid overloading gearbox bearings, and manually rotate the assembly to check for binding before operation. Also confirm pinion seating and bearing condition to minimise premature failure.
From a tuning perspective, the 92-tooth spur influences gear ratio outcomes and will change acceleration versus top speed characteristics. Remaining with 64 pitch components provides predictable wear behavior and smooth engagement.
