PROBLEM

Show/hide table

The stack up of tolerances on the 307-8803 and 308-5077 Hose Assemblies in the 269-9190 Air Conditioning Lines Group is allowing the hoses to rub the frame on certain 770 and 772 Off-Highway Trucks. This can lead to vibration and premature failure of the 3E4053 and 187-8661 A/C Fittings.

The 269-9190 Air Conditioner Lines Group has been updated. The 307-8803 Hose Assembly has been replaced with a 3472470/">347-2470 Hose Assembly and the 308-5077 Hose Assembly has been replaced with a 3459891/">345-9891 Hose Assembly.
