Defect
On the loader's intercooler, the intake air supply hose was improperly selected. Repeated pressurization of the hose during operation may cause the hose to crack or fail. This results in insufficient boost pressure, leading to reduced engine output and exhaust emissions that may no longer meet regulatory limits.
Corrective action
Replace the intercooler hose outlet side on all vehicles with a corrected part.
