The Grizzly 660 at a glance

Yamaha Grizzly 660 parts are easiest to choose by repair job for trail, property, hunting-season, plow, or winch work.

If the quad will not crank or stay charged, start with Batteries, Electrical Components, or Starters before moving to the engine, wheels, steering, driveline, and brakes.

PirateMX covers model years 2002 to 2008 with aftermarket parts and used OEM parts from its teardowns; check fitment for your exact year, make and model before you order, and read the note on any used part.

Get your Grizzly 660 starting and charging

A no-start stops plow work cold. For the Yamaha Grizzly 660, use Batteries for battery replacement, Starters for a starter replacement, or Electrical Components for the rest of the starting and charging system.

Clean and tighten the battery connections, then match the terminal layout, connector, and mounting points shown on the product page.

Engine and transmission

Rebuild the Grizzly 660 engine and transmission

Choose by how far the engine is coming apart. For a Yamaha Grizzly 660 piston or top-end job, use Top End Rebuild Kits or Pistons & Rings; if the repair reaches the crank, cases, gearbox, or more of the engine, move to Complete Engine Rebuild Kits, Engines & Parts, or Transmission & Parts.

Before combining parts, read what is in the box and any install note so you do not double up on a piston, gasket set, or other kit piece.

Tires and wheels

Start at the end of the ATV that needs work. On the Yamaha Grizzly 660, Front Wheels and Front Tires cover the front, Rear Wheels covers the rear, and Wheels & Rims or Tires & Tubes handles the broader wheel or tire job.

Match the tire size printed on the sidewall, wheel position, and bolt pattern to the product page, and buy tires new.

Play at the bars or wheel can come from several joints. For the Yamaha Grizzly 660, Ball Joints Bearings Bushings covers joint and pivot wear; Steering Components or Steering Stems & Columns covers steering damage, Shocks & Struts covers worn shocks, and Rear A-Arms covers rear suspension repairs, while Suspension & Steering handles the wider system.

Safely support the quad and move the wheel and steering through their travel to find where the play starts before choosing the part.

A torn CV boot calls for a closer look before the next trail or property job. Use Yamaha Grizzly 660 CV and Axles for that repair area, Drivetrain for the wider drive system, or Differential Bearing & Seal Kit when the differential needs bearings and seals.

Find the torn boot, axle play, or differential leak, then compare the axle position or kit contents with the parts coming off the quad.

Frequently asked questions

Should I look for used OEM or new aftermarket Yamaha Grizzly 660 parts?

Choose used OEM when you need an original Yamaha assembly, and consider new aftermarket parts for service items or a planned engine repair. Read the note on any used part for its stated condition. For aftermarket pistons, top end kits, and complete rebuild kits, check what is in the box and any install note so you do not order duplicate pieces. Check fitment for your exact year, make and model before you order.
