A brand new aftermarket generator stator built as a direct replacement for the original unit used across a wide span of the Polaris range - the Ranger 500, 570 and 900 utility vehicles, the RZR 900 and 1000 sport side-by-sides, and the Sportsman 570, 850 and 1000 ATVs. It is a compact three-phase stator with a single three-pin plug, restoring the charging output the machine was designed around.
Fitting is plug-and-play: the 126 mm outer diameter, the 54 mm bore and the 19 mm stack thickness follow the factory pattern, and the harness runs 85 mm from the stator to the grommet and a further 290 mm to the plug, matching the original routing so nothing needs extending or splicing. The windings are the highest grade copper insulated to withstand 200 degrees Celsius, laid on the highest grade lamination material. The connector and the rubber grommet are supplied fitted, and every unit is electrically tested before it is despatched.

Frequently Asked Questions
Will this stator fit without modification?
Yes. It is a plug-and-play direct fit for the Polaris models listed above. The 126 mm outer diameter, the 54 mm bore and the single three-pin plug match the original, and the harness lengths follow the factory routing, so no cutting or splicing is required. Because this stator covers a wide model span, the safest check is the part number on your original unit against the cross reference table.
What is included?
The stator with its harness, the connector and the rubber grommet, supplied fitted. The flywheel, the stator cover and its gasket are not included and should be reused from your machine.
How do I tell whether my old stator has failed?
With a multimeter set to ohms, measure across each pair of Black wires - all three readings should be about 0.4 ohms, within plus or minus 20 per cent, and should be close to one another. A phase that reads noticeably higher or lower than the other two has broken down. Then check each Black wire against the stator body: any continuity to earth means a winding has shorted to the case. The typical symptoms are a battery that will not stay charged, charging voltage that does not rise above battery voltage at speed, or a machine that dies as soon as the winch or lights are used.
Should I replace the regulator rectifier at the same time?
It is worth testing it. On these Polaris machines a failing regulator rectifier can overheat the stator windings and take the new stator with it, so if the old unit failed by shorting to earth, check the regulator before the replacement goes in.
