The recommended oil for the Yamaha Grizzly 550 is Yamalube 4 10W-40 or any 10W-40 engine oil that meets the API service classification of SJ or higher.
The air filter should be inspected and cleaned every 1,000 miles or 160 hours of operation, whichever comes first. Replace it if it is damaged or excessively dirty.
To adjust the drive belt on the Grizzly 550, first remove the left side cover. Then, check the belt deflection and adjust the position of the secondary sheave if necessary. Ensure the deflection is within the specified range in the service manual.
If the Grizzly 550 is having starting issues, check the battery charge, inspect the spark plug for wear, and ensure the fuel supply is adequate. Also, verify that the starter relay and starter motor are functioning correctly.
The recommended tire pressure for the front tires is 5.0 psi and for the rear tires is 5.0 psi. Adjust if necessary based on load and terrain conditions.
Regularly check the coolant level and top up with a 50/50 mix of antifreeze and distilled water. Inspect hoses for leaks and ensure the radiator fins are clean and free of obstructions.
The recommended spark plug for the Grizzly 550 is NGK CR7EB, and the gap should be set to 0.7-0.8 mm (0.028-0.031 in).
Inspect the brake pads for wear and replace them if the thickness is less than the specified minimum. Check brake fluid levels and top up with DOT 4 brake fluid if necessary.
While aftermarket parts are available for the Grizzly 550, it is recommended to use OEM parts to ensure the best performance and compatibility.
To prepare your Grizzly 550 for winter storage, clean it thoroughly, change the oil and filter, add a fuel stabilizer, and disconnect the battery. Store it in a dry place and cover it to protect from dust and moisture.
