NEW PROCEDURE FOR SETTING OF HYDRAULIC POWER LIFT SENSING MECHANISM SENSING MECHANISM AS 
PER DMN 8491.
1. Mount Bearing Bracket (B 00 875 386 00 18) on the Hydraulic Power Lift Housing.
2. Mount Swinging Yoke (B 00 875 386 0019) and Bearing  Pin (B 00 875 386 0709) on the Bearing bracket.   
3. Fit one of the plate out of the three thickness (B 00 875 386 04 13 / 08 13 / 15 13 ) in between sensing  
   Spring & swinging Yoke which should get inserted just by thumb pressure ( Slide Fit ). Remove Feeler Gauge .
4. Fit one of the stopper plates out of the three thickness ( B 00 875 386 00 20 / 02 20 /03 20 ) on the  
   sensing spring.               
6. Insert a Feeler Gauge of 2.5 to 2.9 mm thickness between the mating surface of Bearing Bracket &  
    Swinging Yoke. 
   Secure Sensing Spring (B 00 875 376 03 12) on the Bearing Bracket.
      
7. Measure the gap between the sensing spring & the flat portion of the stopper plate 
   which should be Between 6.7 mm & 7.6 mm. For measuring this gap a metallic strip 
   can be made locally as a gauge  which will have a width of 6.7 mm at one end and 
   7.6 mm at other end.
8. After insuring above procedure, set the position and Draft Angles ( 15 to 20 degrees 
    & 40 to 50 degrees respectively ) as per regular method.
