DESCRIPTION
When replacing the high-pressure fuel pump (1) or transferring the high-pressure fuel pump during an engine replacement, it is very important to make sure the tension collar (2) is installed before reinstalling the fuel pump. The tension collar (L3K9-12-615) can either come off together with the fuel pump or remain in the housing (3) on the engine. Failure to install the tension collar will result in excessive engine noise and the subsequent failure of the high-pressure fuel pump and the camshaft cam lobe the tension collar rides on.
