Snow Blower Copper Worm Gear 19mm ID 70mm OD 20 Teeth
This is the copper worm gear from the auger gear case of a two stage snow blower, sized 19mm ID by 70mm OD by 18mm thick with 20 teeth, and it is bought by service workshops, dealers and importers who repair gear cases rather than replace whole machines. The copper gear is the sacrificial part in the drive: it is deliberately softer than the steel worm so that a jam in the auger strips the gear instead of breaking the shaft or the housing. A stripped gear means the auger stops turning while the engine still runs, which is the most common reason a snow blower comes into a workshop mid season. The matching worm measures 22*149mm, so the pair can be ordered together and the gear case rebuilt in one go.
- All four dimensions published, 19mm ID, 70mm OD, 18mm thickness and 20 teeth, so fitment is checked before you order
- Matching 22*149mm worm available so a stripped gear set is replaced as a pair rather than mismatched
- Rebuilding the gear case is far cheaper than condemning the machine at the end of its first season
- Held as a shelf spare, it turns a stripped gear into a same day workshop repair
- Ordered alongside the rest of the snow blower accessory range in one consolidated shipment
- Single piece sample orders accepted so a workshop can trial fit before buying volume

Application Scenarios
- Dealer workshops rebuilding auger gear cases after a jam has stripped the gear

Problems It Solves
- A stripped worm gear leaves the auger dead while the engine still runs, and the machine is unusable
- Sourcing an odd gear size mid season often means a long wait through an OEM parts channel
- Fitting a gear without checking tooth count and bore leads to rapid re failure
- Replacing a gear without the matching worm leaves a worn pairing that strips again
- Scrapping machines over a single gear destroys the margin on a rental or dealer fleet

How It Compares
Against Replacing the complete gear case assembly
Changing only the copper gear is a smaller part to ship, store and fit, and it suits a workshop that is already opening the case.
Against A steel gear of the same size
The copper gear is intended to be the softer part in the pair so that a jam sacrifices the gear rather than the worm or the auger shaft.
Against Buying spares through the machine's original dealer chain
Buying direct lets you hold your own stock at manufacturer pricing, which is what keeps a repair inside the same working day.
Use Guide
- Confirm the bore, outer diameter, thickness and tooth count against 19mm, 70mm, 18mm and 20 teeth before ordering
- Stop the engine and disconnect the spark plug lead before opening the gear case
- Inspect the 22*149mm worm for wear at the same time and replace both if the tooth faces are marked
- Refill the gear case with the correct grease or oil before closing it
- Turn the auger by hand through a full revolution to check engagement before restarting
