Service Information Document Title: Checking the compression pressure Function Group: 211 Information Type: Service Information Date: 2014/4/17 Profile: Checking the compression pressure Op nbr ST332270 Adapter for pressure gauge Figure 1 1. Set the control lever to a position in which the fuel supply is interrupted. 2. Disassemble all glow plugs and install adapter (1) ST332270 with pressure gauge (2) to one of the cylinders. 3. Crank the engine with the starter. Compression pressure, see table [Invalid linktarget] The measured compression pressure depends on the starter speed during the measuring process and the altitude of the engine location. Limit values can therefore not be specified precisely. The compression pressure measurement is only recommended as a comparison measurement for all cylinders of an engine. If a deviation of more than 10% is found the respective cylinders should be disassembled in order to detect the cause. 4. Insert all glow plugs and tighten with 17.2 2.5 Nm.
