ABSTRACT:
A clamp (26) has a main body (30) that is attached to an engine block (28). A right-angled flange (32) extends from the main body to enter a downwardly open concave interior of an outturned flange (18) of an oil pan rim (16) and provides underlying support for an insert (46) on which the outturned flange of the oil pan rim rests. Fretting of the rim is avoided because the presence of the insert avoids any substantial contact between the flange (32) and the rim (16) that could lead to fretting.
