PROBLEM

Show/hide table

Certain 320D 2 Excavators have experienced excessive wear of the 138-2053 Valve Lifters (Image 1) resulting in the inability to adjust engine valve lash to within the specified serviceable limits through tappet adjustment alone.
The accelerated wear of the valve lifter may also lead to accelerated wear on the camshaft (Image 2).
New 464-6253 Valve Lifters is an improved part against wear.
