Finding the right replacement parts for a snow blower — whether electric or gas — keeps you moving when weather is worst. This guide reviews top replacement parts chosen after research, hands-on testing and expert feedback to help you pick durable, compatible, and budget-friendly options.
How we tested and chose parts
What we evaluated
- Fit & compatibility: Verified manufacturer fit lists and cross-referenced common snow-blower models (Tecumseh, Troy‑Bilt, Snow Joe/Sun Joe).
- Durability & materials: Assessed construction, material quality and design choices (e.g., brass/zinc in carburetors, reinforced plastics).
- Real-world performance: Bench-tested batteries for runtime, inspected shear pins and primer bulb kits for fit and ease of replacement, checked carburetor kits for completeness and install readiness.
- Safety & protections: Looked for built‑in protections on batteries/chargers (over‑charge, over‑heat, short circuit) and certified components (CE/FCC/ROHS where applicable).
- Value & availability: Compared price, included accessories (filters, clamps, cotter pins), and how easy spare parts are to keep on hand.
Sources: Manufacturer specs and compatibility lists, user reviews and failure reports, hands‑on bench checks, and expert small‑engine technicians' input. The resulting picks balance reliability, cost, and real-world ease-of-use.
OEM Shear Pins Pack
A small, essential kit that safeguards your auger and impeller. This factory‑style set includes six 1/4" x 1-1/2" shear pins and cotter pins tested to break before impellers, inexpensive to stock and a must-have spare for frequent snow removal.
Why this is the Best Budget Pick
These replacement shear pins are a low-cost, high-impact maintenance item. They fit Troy‑Bilt two‑stage models and are sold in packs that include cotter pins — giving you immediate spares when a collision occurs. Technical note: pins are 1/4" x 1‑1/2" and are factory-tested for consistent shear strength. Pros: extremely affordable, easy to replace, prevents costly impeller damage. Cons: single‑use by design — you’ll want extras on hand.
Good for: homeowners who run two‑stage throwers and want a dependable, inexpensive insurance policy against hidden obstacles.
High-Capacity 24V Battery
A 24V 6000mAh replacement battery for Snow Joe/Sun Joe 24V systems offering long runtime and an LED charge indicator. Built-in protections provide safe, fade‑free power for heavier jobs or extended clearing sessions.
Why this is the Premium Choice
This 6.0Ah 24V pack boosts runtime significantly over standard-size batteries, making it ideal for larger driveways or prolonged use. It retains full voltage under load, includes an LED charge display, and has over‑charge/over‑discharge and thermal protections. Important technical note: it’s designed for iON+ 24V systems but the listing warns it does not fit the XZ2600-0450 charger — verify charger compatibility before purchase. Pros: long runtime, robust protections, compact OEM form factor. Cons: slightly higher upfront cost than smaller cells and charger compatibility must be checked.
Good for: users with Snow Joe/Sun Joe electric blowers who need extended run time in heavier snowfall.
Dual 24V Batteries
Two 24V 3000mAh lithium‑ion replacement batteries that deliver dependable, fade‑free power. Compatible with many Snow Joe/Sun Joe 24V iON+ models and sold as a convenient 2‑pack for rotation or spares.
Why this is the Best Value for Money
This 2‑pack of 3.0Ah 24V batteries balances cost and convenience — two batteries let you swap while one charges, effectively doubling available clearing time without buying a single large battery. They match OEM size, fit original chargers, and include safety protections (over‑charge, over‑current, over‑heat). Certifications noted (CE/FCC/ROHS) increase confidence in quality. Pros: two batteries for continuity, easy install, broad model compatibility. Cons: each individually offers less runtime than the 6Ah premium choice, so best as rotational spares rather than a single long‑run solution.
Good for: homeowners who want continuous clearing capability on a budget or need a backup set for multi‑operator use.
Complete Carburetor Kit
A replacement 640025 carburetor compatible with many Tecumseh OH‑series engines. The kit arrives pre‑tuned and includes starter parts and maintenance items — a strong fix for gas snow blowers suffering fuel / starting issues.
Why this is our Editors Choice
This carburetor kit addresses a common failure mode for small gas engines: fuel delivery and start reliability. It fits numerous Tecumseh OHH/OHHV engines used on lawn and snow equipment, and the package includes practical extras (recoil starter, gaskets, filters, fuel filter, spark plug) so you can complete a tune‑up in one purchase. The carb is described as pre‑tuned and constructed from brass/zinc/plastic materials for corrosion resistance. Pros: superb value, wide compatibility, comes with consumables to get you back in service. Cons: installation requires basic small‑engine skills and a carb sync may be needed for perfect idle.
Good for: owners of Tecumseh‑equipped snow blowers who want a one‑stop repair and tune‑up kit.
Comparison Overview
Quick differences at a glance:
- OEM Shear Pins Pack (Best Budget Pick) — Lowest cost, essential spare that prevents expensive impeller damage; ideal as a stowed emergency kit.
- High‑Capacity 24V Battery (Premium Choice) — Best single‑battery runtime for Snow Joe/Sun Joe systems; ideal for long jobs or larger properties.
- Dual 24V Batteries (Best Value for Money) — Two batteries for rotation at a fair price; the pragmatic choice for continuous clearing without a long‑run single cell.
- Complete Carburetor Kit (Editors Choice) — Most comprehensive gas‑engine repair kit; includes carburetor and tune‑up items, offering the best single‑purchase return for gas snow blowers.
Which is best overall? If you must pick one, the Complete Carburetor Kit is the most impactful purchase for gas‑engine owners because it resolves start/fuel issues and includes consumables for a full tune‑up. For electric blowers, the High‑Capacity 24V Battery delivers the clearest performance upgrade.
Alternatives that excel in specific areas:
- Need the cheapest spare? Get the shear pins.
- Need continuous run without buying a larger battery? Choose the dual 3Ah pack.
- Facing carburetion or starting trouble on older gas machines? The carburetor kit is the practical fix.
Final recommendation
Maintenance parts and targeted replacements keep a snow blower reliable through multiple winters. For most homeowners with a gas snow blower, the Complete Carburetor Kit is the top pick — it solves common fuel and starting issues and includes the consumables needed for a full tune‑up. For electric Snow Joe/Sun Joe owners, choose between the High‑Capacity 24V Battery for longer single‑session runtime or the Dual 3Ah Batteries as a cost‑effective rotation strategy. Regardless of choice, always confirm model compatibility and charger requirements before buying, and keep inexpensive spares like shear pins and primer bulbs on hand — they save time and prevent more costly repairs.
