Polaris Ranger 900 Engine Rebuild Service (2013–2016)

The Polaris Ranger 900 earned its reputation by putting in work day after day. When the engine starts to lose power or consistency, it doesn’t just affect performance—it slows everything down. A full rebuild gets it back to doing what it was built for.

Instead of replacing parts one at a time, we go through the entire engine. Every component is inspected, corrected, and brought back into proper working condition so it runs the way it should from the start.

What Gets Corrected During the Rebuild

This process focuses on restoring internal condition—not just swapping parts, but fixing wear across the engine.

• Complete teardown and inspection of all components
• Cylinder head rebuilt, cleaned, decked, and set to proper specification
• Exhaust valve guides upgraded with manganese bronze material
• Intake valve guides inspected and serviced as needed
• Valve sealing surfaces corrected and vacuum tested
• Camshaft components cleaned, polished, and inspected
• Crankshaft verified within OEM tolerances
• New high-babbitt main and rod bearings installed
• Cylinders inspected and reconditioned to restore proper finish
• New moly-coated pistons and rings installed
• Timing chain and oil chain inspected and serviced
• Refurbished oil pump assembly
• Engine cases inspected and machined where required
• All gaskets and seals replaced
• Final assembly torqued to factory specifications

Built to Stay Working

This engine is meant to handle real use—hauling, towing, and long hours. That’s why every build goes through two sets of eyes before it leaves the shop.

One technician assembles the engine. Another inspects it. That extra step helps prevent problems before they show up in your machine.

Warranty Coverage

Every engine includes a 1-year warranty. If you want added protection, a 2-year no-fault option is available.

Review full details on our warranty policy.

Core Options

Send in your original engine core or choose the refundable $1200 core option. Once your core passes inspection, the deposit is returned.

If you need your engine first, ask about our exchange options and we’ll walk you through the process.

Looking for Parts Instead of a Full Engine?

If your engine doesn’t need a full rebuild, you can find top-end kits, bottom-end components, and individual parts for this machine in our
Polaris Ranger 900 parts catalog.

If you’re not sure which route makes the most sense, reach out to our team and we’ll help you figure it out.

Before You Put It Back to Work

Break-in matters. It helps everything seat properly and sets the tone for long-term reliability.

Follow the engine break-in procedure or review the FAQ page if you need guidance.
