Refine Your Gear Ratio with the HOBBYWING 19T Pinion

The HOBBYWING 19T 5mm 32P Steel Pinion Gear 86040010 is a compact way to refine how your RC truck delivers power. Built from chrome steel, it allows gear swaps to prioritise either stronger torque or higher speed while remaining simple to install.

Pinion Tooth Count and Drive Behaviour

Changing the pinion tooth count alters the gearbox ratio. A smaller tooth count amplifies torque at the wheels for quicker acceleration and better low speed control, whereas a larger tooth count moves the balance toward top speed for straight sections.

Compatibility Notes and Material Details

The component has a 5mm bore, a 0.8mm modulus, and is manufactured from 40CR steel for enhanced durability. It suits many 1/8th scale monster trucks including E-MAXX, E-REVO, and SUMMIT models, making it a versatile choice for different driving conditions.

Which shaft sizes are compatible with this pinion?

This pinion has a 5mm bore so it fits motor shafts of the same diameter; confirm the pitch is 32P to ensure correct engagement with your spur gear.

Will changing the pinion void warranty?

Altering gearing is a common modification; check your vehicle or motor warranty terms, but swapping an aftermarket pinion is generally an accepted tuning step when installed correctly.

How do I check gear mesh after fitting?

Set a small tooth-to-tooth clearance using the motor mount, apply a thin film of gear marking compound or grease to test contact, then adjust until the contact patch is even across teeth.
