PROBLEM

Incorrect oil viscosity was mistakenly used to fill the differentials and final drives of certain 825H Soil Compactors and 826H Landfill Compactors during manufacturing. The correct oil viscosity is 5P-1228 SAE 50. The oil should be changed as soon as possible to provide the best oil film thickness protection for new component break-in and high load applications.
