Checking/Correcting Basic Setting of Compensation Elements
NOTE: The test gauge serves to find the basic position or a plus (+) or minus (-) deviation of hydraulic element.
In the event of a plus (+) or minus (-) deviation, the installation of a thinner or a thicker thrust piece (4) permits to reattain the basic position.
Since December 1982 the hydraulic valve clearance compensation elements have been set with a modified preload size (previously 0.7 - 1.9 mm; now
1.2 - 2.4 mm).
This is achieved by adding a thicker thrust piece to the valve spring retainer.
Production Breakpoint: December 1982
The revised preload dimension is also valid for all previously manufactured engines 116 and 117, and must be taken into account when checking and
adjusting the basic position.
NOTE: Checking and adjusting should be carried out with the testing gauge 117 589 06 23 00 with revised measuring groove position.
Checking
1
With newly installed compensating element, crank engine with starter motor for approx. 30 seconds prior to checking.
