Genuine Polaris Crankcase Baffle Plate – RZR 800 (OEM Part 5253617)

Product Overview: Genuine Polaris Crankcase Baffle Plate

Maintain proper internal oil control and structural integrity within your engine block with the authentic Polaris Crankcase Baffle Plate (OEM Part #5253617). Engineered specifically for the 800cc parallel-twin engine architecture found in Polaris RZR side-by-sides, this internal component plays a critical role in managing oil splash, controlling crankcase pressure dynamics, and preventing excessive oil sloshing during aggressive cornering, hill climbs, and rough trail riding.

When rebuilding an engine or addressing internal maintenance, replacing worn or damaged baffle components ensures your lubrication system functions exactly as factory engineers intended. Available directly through PolarisPartCanada.com, this essential engine replacement component ships quickly right to your door anywhere in Canada.

Compatibility & Fitment

Precision-engineered by Polaris for specific 800cc side-by-side engine configurations:

• Primary Vehicle Compatibility: Fits Polaris RZR 800, RZR S 800, and RZR 4 800 models spanning model years 2008 through 2014.

• OEM Part Number: 5253617 (superseding legacy part #5249837)

• Application: Internal engine crankcase oil management and baffling.

Note on Fitment: Always verify your exact engine serial number, model year, and factory parts diagram before undertaking internal engine teardowns to ensure correct component matching.

How It Works & Functional Engineering

The crankcase baffle plate mounts internally within the engine block, acting as a physical barrier between the rotating crankshaft assembly and the oil sump pool.

By interrupting oil droplets churned up by high-speed crank rotation, it reduces oil aeration (foaming) and helps direct oil efficiently back down to the pickup area while maintaining balanced pressure zones across the crankcase chambers.

Performance Benefits

Equipping your engine build with a genuine Polaris crankcase baffle plate delivers immediate practical advantages:

• Aero-Control & Oil Protection: Minimizes oil foaming and aeration caused by high-RPM crankshaft rotation.

• Precise OEM Fit: Engineered with exact bolt hole patterns and clearance contours to drop straight into the RZR 800 crankcase without modification.

• Reliable Engine Longevity: Protects internal lubrication efficiency during extreme off-road angles, steep inclines, and heavy G-force maneuvers.

• Structural Integrity: Manufactured from high-grade factory materials designed to withstand continuous thermal cycling and high-stress engine vibrations.

Build Quality & Materials

Manufactured to stringent industrial standards under strict quality control guidelines:

• Material Construction: High-strength stamped steel or specialized alloy treated to resist oil degradation, heat warping, and chemical breakdown.

• Tolerances: Built to strict factory specifications to ensure proper clearance from moving internal rotating components.

Installation & Setup Instructions

Internal engine component—professional mechanical installation is strongly recommended:

1. Engine Teardown: Ensure the engine is completely removed, drained of all fluids, and mounted securely on an engine stand before splitting the crankcase halves.

2. Clean & Inspect: Thoroughly clean the crankcase mating surfaces and inspect all surrounding bearing journals and fastener threads.

3. Position Baffle Plate: Align the genuine Polaris baffle plate (Part #5253617) precisely with the factory locating dowels and bolt bosses inside the crankcase housing.

4. Torque Fasteners: Secure using appropriate thread-locker where specified and tighten all retaining screws to exact factory torque specifications in a cross-pattern sequence.

5. Check Clearance: Manually rotate the crankshaft to verify total freedom of movement and ensure zero physical contact against the newly installed baffle plate before closing the crankcase.

Durability & Canadian Climate Resistance
