General Information

Drain Plug, Left (2):

NOTE: The engines 117.960 (1st version) with intermediate flange, up to end No. 001681, with the exception of engine end No. 001613-001617 and 001636-001640, were fitted with a one-piece oil pan together with a gasket coated on one side with graphite, similar to the engine 117.985, however with additional supporting angles between engine and intermediate flange.







The engines 116.960 and 117.960 (2nd version) as well as 116.962 and 117.962 are fitted with the one-piece oil pan, the engines 116.961/963 and 117.961/963 are fitted with the two-piece oil pan, both with integrated supporting angles, together with a gasket graphite-coated on one side.

The hole pattern for the oil pan of all engines 116.96 and 117.96 are identical and differ from the hole pattern for the cast-iron engines 116.98 and 117.98.

A protective bead was added in the area of the oil drain plug at the oil pan lower part in order to avoid engine cracks.

If the refrigerant compressor carrier is bolted to the crankcase during oil pan removal and installation it is necessary to ensure tension-free assembly.

The carrier (steel version) must be checked for distortion. There should be no gap between contact points of the support angle and the crankcase. This condition must be verified before attaching the angle. The bolts must be tightened in the following sequence:









a) Install bolts (17, 6 and 5) finger-tight.
b) Tighten bolts (17) at engine front.
c) Tighten bolt (6) and nut (5) at side of engine.
