Gx 340-390 | 300-Hour Maintenance Kit

It is extremely important to follow the manufacturers maintenance schedule! These engines and pumps will last a very long time with proper maintenance and care. Remember, oil is cheaper than an engine!

At 300 hours Honda recommends an oil change, cleaning or replacement of the air filter, and a new spark plug. Whether you are running a Comet, GP, AR, Udor or any other pressure pump, the pump oil will need to be changed every 300 hours. 

This kit includes everything you need to perform this simple maintenance on your own.

• 1 Quart Mobile1 full synthetic 10W-30
• 1 Quart premium high pressure pump oil
• Gx 340-390 air cleaner replacement 
• Replacement spark plug pre-gapped to Honda specifications
