Stainless Steel Gearbox Shim Set Ø3mm 60pcs – RetroArms

RetroArms stainless steel shim set with a 3 mm bore, for shimming the gears of an airsoft gearbox. Three thicknesses in one pack and each shim laser-marked: axial play can be adjusted precisely and the right thickness is recognised at a glance, even with the gearbox open on the bench.

How it works

Shimming removes axial play from the gears and aligns them with one another: less friction and noise, more even tooth wear and a gearbox that runs more smoothly and efficiently. By combining the three thicknesses, the required spacing can be reached on every axle in fine 0.1 mm steps.

In the workshop

It is the set to keep on the bench for gearbox overhauls and upgrades: the generous supply of all three thicknesses covers several jobs, and the laser marking prevents mixing up thicknesses during test fitting.
