Belts - Inspect/Replace - Air Pump belt
The air pump belt must be replaced at 1000 hours. Refer to Disassembly and Assembly, "Belt (Air Pump) - Remove and Install" for more information.
Belt Tension Frequency
The belt for the air pump must be checked with a suitable belt tensioner meter. The meter checks the vibration frequency of the belt in order to determine the belt tension.
Refer to table 1 for three cylinder engines. Refer to table 2 for four cylinder engines.
