How much does a Craftsman 5000 watt generator cost?
A Craftsman 5000-watt generator price depends on the exact model, condition (new vs. used), and included features (electric start, fuel tank size, outlets). For your Craftsman model 580327181 (a 7500-watt AC generator), use the parts list and specs in the owner's manual to confirm what you have before comparing prices.
Generator pricing varies widely, but these factors drive the biggest swings:
- Wattage class (5000 running watts vs. 6250, 7500, etc.)
- Starting watts (surge) capability for motor loads (well pump, compressor, A/C)
- Condition (new, refurbished, used) and maintenance history
- Features (electric start, wheel kit, multiple receptacles, circuit breakers)
- Local market and seasonality (storm season demand)
Your model page is for a Craftsman 580327181 7500-watt AC generator, so it is not the same as a “Craftsman 5000 watt generator” listing.
| Item you are pricing | What to verify | Where to confirm |
|---|---|---|
| “Craftsman 5000 watt generator” | Exact model number on the unit | Owner's manual (model ID format) |
| Craftsman 580327181 | Rated wattage and load guidance | Owner's manual (specs and wattage reference guide) |
If you compare prices using only “5000 watt,” you can end up looking at the wrong generator class. The 580327181 manual also highlights that many motor-driven tools need higher starting watts than running watts, which affects what the generator can realistically power and what buyers will pay.
A generator that starts easily and runs smoothly typically sells for more. Common maintenance and repair items for model 580327181 include:
- Spark plug 72347 (tune-up and hard-start issues)
- Nikki carb 0A4600 (surging, fuel delivery problems)
- Fuel cap 846987 (fuel system sealing and venting)
- Breaker 87962GS (output protection and nuisance trips)

What are the parts of a simple electric generator?
A simple electric generator is built around a rotating conductor (armature/rotor) moving through a magnetic field (field windings/stator) to produce electricity; current is collected through brushes and a commutator (or slip rings). For your Craftsman 580327181 generator, the owner's manual shows the main user-facing components such as receptacles, breakers, and engine controls.
Most basic generators include these electrical building blocks:
- Armature (rotor): the rotating windings or conductor where voltage is induced
- Field windings (stator): stationary coils that create the magnetic field
- Brushes: spring-loaded contacts that transfer current between stationary and rotating parts
- Commutator or slip rings:
- Commutator is common in DC generators
- Slip rings are common in AC alternators
- Voltage regulation (varies by design): helps stabilize output as load changes
The 580327181 is a 7,500-watt AC generator with multiple receptacles and protective devices. Common components called out in the manual include:
- Circuit breakers (push-to-reset) to protect against overload
- 120V and 120/240V receptacles for powering tools and appliances
- 12V DC receptacle for charging a 12V battery (not for starting an engine)
- Run/Stop switch and choke lever for starting and stopping
- Idle control switch to reduce speed when no load is present
| Simple generator term | What it does | What it looks like on a portable generator |
|---|---|---|
| Rotor (armature) | Spins to generate voltage | Internal rotating assembly (not usually visible) |
| Stator (field windings) | Creates magnetic field/output windings | Internal stationary windings |
| Brushes | Transfers current (if used) | Internal wear item on some designs |
| Breakers | Protects from overload | Reset buttons near receptacles |
Knowing these parts helps you troubleshoot “no power” problems logically: engine running but no output often points to the alternator section (rotor/stator/brushes/regulation) or an open breaker, not the fuel system.

How do I find the model number on my 580327181?
The model number for your Craftsman 7500-watt AC generator is printed on the generator’s identification label; it will read 580.327181. Use that exact number when ordering parts, matching diagrams, or following procedures in the 580327181 owner's manual.
Check these common label locations on portable generators like model 580327181:
- On the control panel area (near outlets and breakers)
- On the frame rail near the engine mount
- Near the recoil starter housing or engine shroud
- On or near the fuel tank support area
- On a metal tag or durable sticker attached to the cradle/frame
Record the full model number and any extra identifiers on the tag so you get the right Craftsman generator parts.
| What to capture | Example | Why it matters |
|---|---|---|
| Model number | 580.327181 | Ensures correct parts list and wiring diagram |
| Product description | 7500 Watt AC Generator | Helps confirm you are in the right manual |
| Part/document number (if shown) | B1901 (manual part no.) | Helps match the correct documentation |
- Wipe the tag with a damp cloth and mild soap; dry it fully
- Use a flashlight at an angle to make faded printing stand out
- Take a close-up photo and zoom in
- If the sticker is damaged, compare your control panel and frame to the diagrams in the manual
Craftsman generator parts can vary by model and production run; using 580.327181 helps you match the correct wiring diagram, control panel components, and engine-related parts.
