Bearings; V-Belts - Norton GC55 Owner's Manual

Always refer to the engine manual for more detailed information on checking
the oil, changing oil, and oil capacity, air filter changes, and fuel type to use.
Use only Honda air filters. Do not clean the air filter with gasoline or other
flammable solvents. A fire or explosion could result. To clean, follow the
instructions found in the Honda engine manual.
Dry Cutting Engine Maintenance
• When operating the engine in dry cutting or dusty environments the
following is required:
• Engine oil changed more often.
• Every 50 hours (or more often if conditions require) clean all of the engine
cooling fins.
• Every 25 hours (or more often if conditions require) clean the engine pre-
cleaner.
• Every 100 hours (or more often if conditions require) replace the air filter.
If the engine is equipped with a reusable air cleaner, clean and re-oil it.
• Check and clean the air filter after each use. Replace as needed.
B. Bearings
The GC55 and GC25E are equipped with permanently sealed blade shaft and
wheel bearings that will never need any lubrication. These types of bearings
are designed for long life and minimum maintenance. If any problem occurs
with the blade shaft, or wheel bearings replace the bearing.
The only the Raise Screw and Cutting Head pivot point will need periodic re-
lubrication. Both of these points require just a squirt of a good quality NLGI
#2, aluminum complex type grease is recommended one time a month.
Check the function of the Hand Wheel and Cutting Head before each use.
Lubricate the Raise Screw and Cutting Head pivot point once a month or
when the it becomes hard to turn the Hand Wheel.
C. V-Belts
Warning: Never make adjustments to belts or pulleys while
engine is running!
1. The best tension for a belt drive is the lowest tension at which the belts will
not slip under full load.
2. Simply take up the drive until the belts are snug in the grooves. Run the
drive for about 15 minutes to "seat" the belts. Then impose the peak load.
If the belts slip, tighten them until they no longer slip at peak load.
