PROBLEM

A bypass orifice needs to be drilled in the manifold on certain 815F Soil Compactors and 816F Landfill Compactors. A batch of 7V6589 Manifolds missed a manufacturing process to drill out a bypass orifice. This orifice allows viscous oil to bypass in cold operations. If this orifice is not drilled, the result will be higher operating pressure in the steering system, which could cause leaks or damage to hoses and the hydraulic oil cooler.
