Identifying the correct component
Stock number 303160987A is what to quote if you email us to check a fit, because it removes the guesswork entirely. Model names persist for years while the components underneath them do not.
Check the mating surfaces and fasteners while the assembly is open. Photograph the arrangement before you strip it.
Where to find the stamped number on each part is covered in the snow blower repair guide. If the stamping has worn away, a clear photograph of the part in place is usually enough for us to identify it.
Signs it has reached the end
If the machine is doing any of the following, this is the component to examine first.
- play or movement where the assembly should be solid
- uneven wear across a surface that should wear evenly
- a noise that follows machine speed rather than engine speed
- a repair that did not hold through the season
- a component that is visibly worn, cracked or distorted
Replaced once, correctly, this rarely comes up again. Order before the first forecast moves demand and the item is on a shelf rather than on a backorder.
Fitting it
Isolate the machine before you start. Nothing on this job needs the engine turning. Photograph each stage as you go. It takes seconds and saves an hour at reassembly.
Work clean. Grit introduced during a repair is a failure two winters later. A side by side check catches the small dimensional differences that photographs never show.
Use the clearing tool clipped to the handle. That tool exists because a stored impeller does not care how careful you are. The same rule applies whenever the auger housing is open.
Canadian winters and this part
Canada is not one snow market. In Atlantic Canada the pattern is depth, wind and salt air arriving together. Stock moves quickly once the snow starts, which is the only real argument for ordering early.
Freight across the country slows once the first storms arrive, so autumn is when a spare actually reaches you quickly. Thirty year normals for your own station are published free by Environment and Climate Change Canada.

Reading the listing

This line is 303160987A. Get that right and the rest of the order takes care of itself.
What else to check
A repair is cheapest when everything that needs doing is done at the same time. Do not close the assembly without checking the fasteners you have just disturbed. Look at the bearings for play and roughness before you close it up. Give the seals at every shaft exit a proper look while access is easy.
None of those are expensive, and snow blower parts has them by number. the maintenance checklist sets out the seasonal order to work through them in, and the snow blower repair guide covers what to do when one of them turns out to be the real fault.
Planning ahead for February
There is a short list of components that fail during a storm, and every one of them is inexpensive if bought before the storm. Keep the stock numbers written inside the machine cover and reordering takes under a minute.
All of it sits on snow blower parts and ships Canada wide from stock held here. October is the quiet month for this. February is not, and freight times show it. Store it off a bare concrete floor. Concrete wicks moisture and rusts steel from the underside where nobody looks.
People shopping for a snow blower anti usually start with price and end with availability. The sensible order is the reverse. Establish that a snow blower anti of this type suits your surface and your typical snowfall, then compare what the market charges for it.
The market for a snow blower anti in Canada is thinner than it should be, which is part of why we stock this properly. A snow blower anti that nobody carries parts for is a machine with an expiry date.
Common questions
What are the symptoms that this needs replacing?
a component that is visibly worn, cracked or distorted; a fault that returns after the obvious causes are eliminated; play or movement where the assembly should be solid. Any one of those is worth acting on before the next storm.
Is a generic equivalent acceptable?
Sometimes, and often not. Pitch, grade, profile and length are all specified. Where a genuine part is unavailable we will say so rather than sell you a guess.
How quickly does it ship?
Stock items leave the same or next business day. Ordering in autumn rather than mid storm is the single biggest factor in how fast it reaches you.
Can I fit it myself?
In most cases yes. Check the mating surfaces and fasteners while the assembly is open. Work with the plug lead pulled on a petrol machine and the pack out on a cordless one.
What else should I check while it is apart?
Whatever the component touches. Bearings, seals, fasteners and belts are cheap while the assembly is open and expensive once it is closed.
How do I know this fits my machine?
Order by stock number 303160987A. The same model frequently ships with different components across production years, so the stamped number is the only reliable identifier.
