MOTO1988 Water Pump Rebuild Kit for Polaris 2002–2017 (OEM 3610075) — Impeller, Seals & Driver

Complete water pump seal rebuild kit that replaces impeller, seals, bearings and driver to restore reliable pump operation on many Polaris Ranger, RZR and Sportsman models (2002–2017).

If your Polaris is losing coolant circulation, showing overheating symptoms, or the pump housing leaks, this MOTO1988 rebuild kit supplies the common wear parts needed to rebuild the water pump without buying a full assembly. The kit includes a machined aluminum impeller, bearing, mechanical and oil seals, a cover/backside seal and the driver—matching OEM reference 3610075—so you can return flow and sealing performance to spec when installed correctly.

Which Polaris models will this rebuild kit fit?

This kit covers a broad range of Polaris machines built between 2002 and 2017, including Frontier, RZR, Ranger and Sportsman variants. Use the model list and OEM number 3610075 to confirm fit, since year and sub-model trims (EFI, EPS, 6x6, LE, Walker Evans editions, etc.) affect compatibility.

• Frontier: 2002–2005 (Touring, Classic)
• RZR: 2008–2014 / 2010–2013 RZR 800 EFI family
• Ranger: 2006–2017 various 700/800 and 6x6 models
• Sportsman: 2003–2014 600/700/800 series (multiple EFI and twin versions)

What parts are included and what do they do?

The package supplies the commonly failed components inside the water pump so you can rebuild the unit rather than replace it wholesale. Each part addresses a specific failure point: the impeller moves coolant, the mechanical seal prevents shaft leaks, and bearings keep the rotor running true.

• Aluminum impeller — restores correct flow and reduces cavitation
• Bearing — supports shaft rotation and reduces play
• Mechanical seal & oil seal — prevent coolant and oil leakage
• Cover seal & backside seal — ensure housing-to-housing sealing
• Driver — couples the impeller to the pump shaft for reliable engagement

How difficult is installation and what should I check before buying?

Installation complexity ranges from moderate to advanced depending on your mechanical experience and tools. Expect to disassemble the pump housing, remove the old impeller and seals, and press or seat new bearings and seals; shop manuals and basic press tools simplify the job. Always compare the OEM number and inspect the pump housing and shaft for wear—severely damaged housings or scored shafts may require replacement instead of rebuild.

• Confirm OEM part 3610075 and year/model references before purchase
• Inspect shaft, bore, and housing for corrosion or scoring
• Use a seal driver or press to avoid damaging new seals
• Have coolant, gasket sealant, and torque specs ready for reassembly

What materials and quality cues should I expect from this kit?

MOTO1988 supplies an aluminum impeller for strength and corrosion resistance, along with factory-style seals and a precision bearing. The kit is intended as a direct-fit service option that meets typical OEM form, fit and function standards for the listed Polaris models—but always verify part fit visually before installing.

• Aluminum impeller resists corrosion and maintains blade geometry
• Pre-sized seals and gaskets for direct replacement fitment
• Single bearing matched to OEM diameters for proper rotor alignment
• Driver included to match impeller coupling design

Who is this for: This rebuild kit is built for Polaris owners, ATV/UTV mechanics and DIY enthusiasts who want to restore water pump performance without buying a full pump assembly. It’s ideal when the impeller, seals or bearings have failed but the pump housing and shaft are serviceable. If you’re restoring circulation, fixing leaks, or performing preventative maintenance on compatible 2002–2017 Polaris Frontier, RZR, Ranger and Sportsman machines, this kit supplies the essential replacement components. If unsure about fit, match your OEM number (3610075) and model details or consult a technician before installing.
