Will this gear fit the stock Savage 21 transmission?

Yes, the gear is intended for the Savage 21 transmission as a like-for-like replacement, but check mesh and shims after installation to ensure proper engagement.

How should I set the gear mesh with a Delrin main gear?

Start with the pinion and spur parallel and use a shim or business card method to achieve minimal backlash, then run and recheck after a short break-in period.

What maintenance helps Delrin gears last longer?

Keep the gearbox clean, inspect teeth for wear periodically, and avoid prolonged exposure to heavy impacts which can accelerate wear on plastic gears.
