Description

The Polaris Scrambler 850 delivers strong performance, but when the engine wears out, a full professional rebuild is the most reliable way to bring it back to life. Each Rev6 engine comes standard with our No-Fault 1-year warranty, and you may upgrade to a 2-year No-Fault warranty for an additional $450. If anything happens during that period, we replace the engine—no questions asked.

ENGINE FEATURES & REBUILD PROCESS

Your remanufactured Rev6 engine includes the following:

• Standard 1-year No-Fault warranty, with an optional 2-year upgrade.
• OEM components restored and reused whenever possible to ensure reliable, long-lasting internals.
• Complete teardown, cleaning, inspection, and repair of all engine components.
• Cylinder head cleaned, sandblasted, decked, rebuilt to factory spec, and fully inspected.
• Valve guides inspected and replaced as needed.
• Valves and seats recut/refaced to ensure a tight seal and verified with vacuum testing.
• Camshaft lobes and journals cleaned and polished; replaced when necessary.
• Crankshaft inspected and verified to meet OEM tolerances.
• Main and rod bearings replaced with new high-babbitt coated bearings.
• Cylinders inspected for wear; bored and honed to oversize when needed or resleeved if required.
• New moly-coated pistons and rings installed.
• Timing chain inspected and replaced as needed.
• Refurbished oil pump assembly for proper lubrication.
• Engine cases machined, cleaned, and inspected for cracks, journal wear, or damage.
• All gaskets and seals replaced with new components.
• Engine assembled and torqued to manufacturer specifications.

THE REV6 QUALITY STANDARD

Every engine goes through multiple inspection stages and a final quality-control review. With over 60 years of combined powersports experience, our technicians follow strict processes to ensure every Scrambler 850 engine leaves the shop performing as good as new.

DOUBLE-INSPECTION GUARANTEE

Your engine is assembled by one master technician and then inspected by another. This additional layer of review helps ensure long-term reliability and premium build quality.

CORE OPTIONS

To receive your Rev6 engine, you must send in your original core or pay a refundable $1200 core charge. If your core passes inspection, the full amount is refunded. If you already have a good core ready, you may send it in before shipment. For customers who qualify, a core-exchange option is available if you prefer to receive your rebuilt engine before returning your own.
