PROBLEM

Show/hide table

The existing pipe assembly in the cooling lines group may need to be replaced on certain 330D, 336D, 336D2, 340D, and 340D2 Excavators. The existing pipe assembly may have a crack by stress concentration on the weld toe end of the bracket. It may cause the engine to power down due to intake air leaks from the crack.
