Polaris Ranger 570 Engine Rebuild for 2022–2026 Models

If your Polaris Ranger 570 engine has low compression, excessive oil consumption, or bottom-end noise, this rebuild service brings it back. Instead of replacing the entire unit, this process restores your original engine and strengthens long-term reliability. As a result, your machine runs smoother and holds up under load.

Before You Buy — Verify Key Components

This rebuild uses a crankshaft that replaces OEM part number 2206356. The tapered end of the crankshaft measures 25mm just behind the threaded flywheel end. The cylinder head corresponds to OEM part number 3022860 and uses a flat graphite exhaust gasket with a flush-mounted header pipe.

Because Polaris made crankshaft changes in 2017 and mixed cylinder head usage starting in 2021, you should confirm both the MAG end diameter and exhaust port style before ordering. This step helps prevent fitment issues and ensures correct parts for your machine.
