(f) Install the new EIPC 79-35-21-01-090 FACE SEAL (4) between the ODM sensor (1) and the tube (LR03) flange:
1 Examine current face seal to see if it can be used again by the procedure that follows:
a No raised material on the metal surface.
b Rubber that is not bonded to the metal surface is not permitted.
c Rubber that is missing is not permitted.
d Examine rubber seal for separation from the metal surface.
e Rubber that is cut or damaged is not permitted.
f Make sure that the rubber material is above the metal surface.
g Replace the EIPC 79-35-21-01-090 FACE SEAL (4) if necessary.
(g) Attach the bracket (3) and tube (LR03) to the housing with the three bolts (2).
(h)
