Longer Hoses Used At Radiator Lower Hose Connections{1380}
Usage:
3408 and 3412 Industrial Engines
Description of Change: Longer hoses are now used on the radiator lower hose connections of 3408 and 3412 Industrial Engines. The longer length permits more hose to fit under the clamps. This gives a larger area for the clamp to grip and hold the hose in position.
Adaptable As: Direct replacement as shown in the chart.
