The engine S63 TOP has a volume flow rate controlled oil pump with pressure stage and compression stage in the same housing. The oil pump is securely screwed onto the upper part of the oil sump.
The oil pump is driven via the sleeve type chain from the crankshaft. The sleeve type chain is kept under tension by a tensioning rail.
A pump is used as a vacuum stage, which delivers the engine oil from the front oil sump area to the rear oil sump area with an additional intake pipe.
The volume flow controlled pendulum slide cell pump is used to supply the engine with oil pressure. The intake snorkel is positioned in the rear area of the oil sump to ensure safe oil supply.
The graphic below shows the oil sump components and their drives.
