Tune Your Drive with the Hobbywing 17T

The Hobbywing 17T 5mm 32P Steel Pinion Gear 86040000 is made for drivers who want repeatable gear swaps to match track or terrain. The steel build is aimed at longer service life under hard use and frequent ratio changes.

Ideal Models and Setups

Common fits include 1/8 scale monster trucks like the E-MAXX, E-REVO and SUMMIT and many 1/10 machines such as the SLASH 4x4. Changing to the Hobbywing 17T lets you balance low end torque against top speed so you can set up for tight technical runs or faster circuits.

Specification Highlights

Key dimensions are a 5mm bore and 0.8mm modulus, and the pinion is produced from 40CR steel for accurate tooth profiles and improved wear resistance. These specs support consistent gear engagement across sessions.

Do I need new bearings when fitting this pinion?

Not always, but inspect bearings for play or roughness during installation. Worn bearings can cause poor mesh and premature gear wear.

Is this suitable for high torque brushless setups?

Yes, the 40CR steel construction handles higher loads better than softer materials, though proper cooling and motor tuning remain important to protect the drivetrain.

How should I check gear mesh after installation?

Fit the pinion and spur, add a strip of paper between teeth, tighten the pinion, then rotate gears to seat them and remove the paper. There should be a slight amount of clearance across the teeth.

Can I polish or modify the pinion teeth?

Minor deburring is fine to remove machining marks, but avoid reshaping teeth as that can affect mesh and cause uneven wear.
