The G9U 730 engine is available with a power take-off that is driven by the engine accessory drive belt.
Power take-off is available only on vehicles without air conditioning. The engine accessories layout is the same as that for an engine with air conditioning, but the air conditioning compressor is replaced by the power take-off drive.
An idler pulley assembly (1) is installed on vehicles that are to have the power take-off service installed. The power take-off assembly replaces the idler pulley assembly.
