Quick OFNA Truggy gear pitch question
I'm converting an old MBX R2 (truggy conversion years ago) to brushless. Neither 32P or 48P mesh with the spur gear. What pitch do I need?

I feel like a broken record:

That link I posted is the most economical part that is likely compatible from the same OEM
According to this manual here for the Ultra MBX R2 they specify the stock spur as #31040

I've ran enough HongNor cars that chances are you may get a full diff to work as well if you measure the bearings and distance between the slots in the diff mount then ask someone on RC Tech to measure and confirm:

After you take your measurement (outer bearing to outer bearing) and verify bearing diameter, then ask someone on this thread to confirm measurements:

I still have the original center diff and it includes the 31040 spur gear. When the truggy kit was installed, it included a solid shaft to replace the diff and an ONFA 18163 65T spur gear to compensate for the larger tires. Neither the 31040 or 18163 spur gears have a 32 (or 48) pitch. The bell clutch / 31040 and 18163 spur gears have a 22P. So purchasing the 31040 will not work when converting to brushless.
