Should I spray my snowblower with WD-40?
Yes, you can spray a light coating on the Craftsman 486248462 snow thrower attachment to help reduce snow sticking and to help protect bare metal from rust. For best results on the chute and housing, we recommend a silicone spray or a non-stick protectant; original WD-40 works short-term but does not last as long.
What to spray (and what not to)
Use a light coat and keep spray off belts, pulleys, and any friction surfaces.
- OK areas: inside of the discharge chute, inside of the auger housing, chute ring contact area (lightly)
- Avoid: drive belt and auger belt, idler pulleys, clutch/idler assembly, any braking or traction surfaces
- Best choices: silicone spray (longer-lasting slick film), seasonal non-stick spray made for snow equipment
- If using original WD-40: treat it as a quick water-displacing, short-duration option
- After washing: a light oil film on exposed metal helps prevent rust during storage
For model-specific lubrication points and where the manual calls for oil vs spray lubricant, follow the lubrication section in the 486248462 owner's manual.
Quick steps for the Craftsman 486248462
- Shut off the tractor engine, remove the key, and let moving parts stop.
- Brush out packed snow and ice; let the attachment cool to outdoor temperature.
- Apply a thin coat to the inside surfaces (wipe excess so it does not drip).
- Cycle the chute rotation and tilt to spread the film.
Where the manual focuses lubrication
The manual emphasizes oiling pivot points and using spray lubricant on controls and cables; it also notes that a light coat of wax can help prevent sticking inside the housing and chute.
| Area | What to use | Goal |
|---|---|---|
| Chute and housing interior | Silicone or non-stick spray | Reduce clogging and sticking |
| Pivot points and idlers (as specified) | Oil (per manual) | Smooth movement, less wear |
| Belts and pulleys | Nothing | Prevent slipping and belt damage |
Why it matters
A slick, dry film inside the chute helps wet snow slide through instead of building up and clogging. Keeping lubricant off belts and pulleys prevents slippage that can reduce throwing performance.

Are snowblower shear pins universal?
No, snowblower shear pins are not universal. For Craftsman model 486248462, the augers are designed to use a specific shear bolt and lock nut so the bolt breaks at the right load to protect the auger shaft and gearbox; using a “close enough” pin can cause damage.
What this means for Craftsman 486248462
In the 486248462 owner's manual, the spiral augers are secured with shear bolt 710-0891 and hex lock nut 43064. Those specs matter because the bolt is intended to shear if the auger hits a foreign object or jams in ice.
- Match the OEM part number (not just diameter and length).
- Avoid substituting a standard hardware-store bolt; the grade and shank style can be wrong.
- Replace only the sheared bolt(s); inspect the auger and housing for damage first.
- Keep spares with the attachment so you are not stuck mid-storm.
Quick fit check (what must match)
| What to match | Why it matters | What can go wrong if wrong |
|---|---|---|
| Diameter and length | Ensures proper fit through auger and shaft | Slop, binding, or won’t install |
| Shear rating (bolt grade/material) | Controls when it breaks to protect driveline | Gearbox damage or constant breakage |
| Shank/threads placement | Keeps shear point in the correct location | Bolt may not shear correctly |
| Nut/retainer style | Prevents loosening during vibration | Lost bolt, auger stops turning |
Why it matters
A shear pin is a sacrificial safety device. When it breaks at the correct torque, it helps prevent expensive damage to internal components like the auger gear assembly and shafts.

How many years should a snowblower last?
A snowblower typically lasts 15 to 20 years with normal residential use and consistent maintenance. For the Craftsman 486248462 46-inch 2-stage snow thrower attachment, lifespan is driven less by “age” and more by wear items (belts, skid shoes, scraper) and off-season storage; see the maintenance schedule in the 486248462 owner's manual.
What most affects lifespan
- Maintenance and lubrication: keeping pivot points and moving joints lubricated reduces wear.
- Belt condition and tension: worn or loose belts slip, overheat, and shorten component life.
- Surface type: gravel and uneven surfaces accelerate wear on the scraper plate and shoes.
- Impacts and jams: hitting hidden objects can shear bolts and stress the auger/gear housing.
- Storage: washing off salt and storing dry helps prevent rust and seized hardware.
Wear items to plan on replacing
On the 486248462 attachment, these are common “life-extenders” because they protect the housing and keep performance strong:
- Snowblower scraper blade 24309BL3 (takes the brunt of ground contact)
- Snowblower attachment skid shoe 24279BL1 (sets ground clearance and reduces housing wear)
- Belts and hardware as needed (inspect before each season)
Quick rule-of-thumb table
| Condition | Typical outcome | What to do |
|---|---|---|
| Maintained, stored dry | 15 to 20 years | Follow seasonal cleaning and lubrication |
| Heavy use, poor storage | 8 to 12 years | Replace wear parts early; prevent rust |
| Frequent impacts/jams | Shortened life | Inspect augers, replace shear bolts promptly |
Why it matters
A snow thrower attachment can run for decades, but only if the “sacrificial” parts wear out instead of the expensive assemblies. Replacing skid shoes and the scraper blade on time helps prevent damage to the auger housing and keeps the tractor from working harder than it should.

How to tell the year of a Craftsman snowblower?
For the Craftsman 486248462 46-inch snow thrower attachment, the “year” is not reliably determined from the model number alone. The most accurate way is to read the serial number from the decal on the attachment and use that serial format to identify the manufacturing date.
Where to find the information on model 486248462
We look for the identification decal attached to the snow thrower attachment itself (not the tractor). The owner’s manual calls out that the model and serial numbers are on a decal on the snow thrower.
- Check the attachment frame or housing for a decal that lists MODEL NUMBER and SERIAL NUMBER
- Record the serial number exactly as printed (letters and numbers)
- If the decal is dirty or faded, clean the area and use a flashlight to read it
- Keep the serial number with your paperwork for future parts lookups
For diagrams and the identification note, use the 486248462 owner’s manual.
How Craftsman dating typically works (general guidance)
Craftsman serial numbers are not all encoded the same way across product lines and years. Some serial formats include a date code (month/day/year or month/year), while others require cross-referencing the serial with the manufacturer’s production records.
Common serial-number patterns you may see
| What you see in the serial | What it often means | What to do |
|---|---|---|
| A serial that starts with digits that look like a date | May include month/day and a year digit | Try decoding, then sanity-check against purchase date |
| Letters mixed with digits | Often a plant/line code plus date info | Use the full serial when looking up age |
| Separate engine tag (on self-propelled units) | Engine has its own model/serial | Use the attachment decal for 486248462; engine tag applies to the engine only |
Why it matters
Knowing the approximate manufacturing year helps when you are matching parts, belts, skid shoes, and hardware revisions. For example, wear items like skid shoes and scraper blades are commonly replaced over the life of a snow thrower attachment.
If you are also shopping wear parts for this model, examples include the snowblower attachment skid shoe 24279BL1 and the snowblower scraper blade 24309BL3.

Why won't my snowblower auger move?
On the Craftsman 486248462 46-inch snow thrower attachment, the augers usually stop moving because a shear bolt has broken, the auger belt is loose or broken, or the belt routing/tension is incorrect at the clutch/idler assembly. Use the Craftsman 486248462 owner's manual troubleshooting and belt-routing diagrams to confirm the exact setup.
Safety first
- Shut off the tractor engine and remove the key
- Disengage the attachment clutch
- Wait for all moving parts to stop
- Keep hands out of the auger and chute; use a wooden stick to clear packed snow
Quick checks (most common causes)
- Shear bolts: If you hit a hidden object or ice jams the augers, the attachment is designed to shear the bolts so the gearbox and auger shaft are protected.
- Auger belt condition: A frayed, glazed, stretched, or broken belt will slip and the augers will not turn.
- Belt tension and routing: On this model, the auger belt must be routed over the auger pulley and twisted 1/4 turn to run under the two side idler pulleys; incorrect routing can stop the augers.
What to inspect and what it means
| What you observe | Likely cause | What to do next |
|---|---|---|
| Tractor PTO engaged but augers do not move | Shear bolts sheared | Replace shear bolts and lock nuts (use correct size and install fully) |
| Belt squeals or slips under load | Belt loose or worn | Re-tension using the tensioning chain; replace belt if damaged |
| Belt looks intact but jumps off pulleys | Routing/keeper issue | Re-route belt and verify belt keepers are positioned correctly |
| Auger shaft turns but spirals do not | Shear bolts missing/broken | Replace shear bolts and confirm alignment holes are matched |
Parts that commonly relate to this symptom
If you confirm the belt is the issue, the compatible replacement for this model is the agri-fab lawn tractor snowblower attachment ground drive belt 46961.
Why it matters
A non-moving auger is often a deliberate protection event (shear bolts) or a belt/tension problem. Fixing the root cause prevents repeated failures and helps protect the auger drive components from damage.
