Description
Snow Wolf M82A1/M4 Gearset (SW-02-12)
This is a Snow Wolf gearset, part number SW-02-12, listed for the Snow Wolf M82A1 and M4. The gearset is the heart of an AEG: the motor drives the gears, which in turn pull back the piston and compress the spring to fire each shot. If gears wear or strip, the replica will stop cycling properly, so a replacement set is a common and important repair part.
Snow Wolf is a Chinese airsoft manufacturer known for affordable replicas of less common firearms, including the M82A1 anti-materiel rifle, wartime designs such as the PPSh-41 and Kar98K, and film replicas. Owners of these replicas often find that factory spare parts are the easiest way to keep them running, as many internal parts are specific to the model. The SW-02 series M82A1 is an electric replica, which is why it uses a gearset like an M4-style AEG.
When to replace a gearset
Signs that your gears may need replacing include a grinding noise when firing, the motor spinning without the gearbox cycling, inconsistent cycling or visible damaged teeth when the gearbox is opened. Stripped gears are often caused by a jammed piston, a damaged piston rack or an overly strong spring, so it is worth checking those parts at the same time.
A replacement gearset is also a sensible spare to keep if your rifle is your main gun.
Fitting and shimming
When installing new gears, they should be shimmed so they spin freely without side-to-side play and mesh correctly with each other and the motor pinion. Correct shimming reduces noise and wear and helps the gearbox run efficiently. Gearbox work requires some experience; if you are unsure, have a qualified technician fit the gears.

Compatibility
Listed for the Snow Wolf M82A1 and M4. Gear ratios and dimensions vary between manufacturers and models, so please check your replica model before ordering, and compare the product images with your existing gears.
Care and maintenance
Always remove the battery before working on any electric replica. Keep internal parts clean and use appropriate gearbox grease sparingly on gears and moving parts; too much grease attracts dirt and can slow the mechanism.
Use good quality seamless BBs and a battery suited to your replica, as jams and an incorrect battery are common causes of gearbox wear. If you are not confident working on a gearbox, a qualified airsoft technician can fit the part for you.
