Sealing Flange With Sensor Wheel, Installing

Courtesy of AUDI OF AMERICA, LLC

• The sealing flange with PTFE-seal is equipped with a sealing lip support ring -2-. This support ring serves the same function of a guide sleeve and must not be removed before installation.
• The sealing flange and sensor wheel -1- may not be separated or rotated after being removed from the replacement part packaging.
• The sensor wheel retains the installation position by being located on the locating pin of the :T50010  .
• The sealing flange and seal are one unit and may only be replaced together with the sensor wheel.
• The :T50010  maintains the installation position to the crankshaft via a guide pin, which is inserted into the crankshaft hole.

-- Install the nut -B- just up to the tension surface -A- on the threaded spindle.

-- Tension the :T50010  in a vise -1- by the tension surface -A- on the threaded spindle.

-- Push the assembly bell -D- downward in direction of -arrow- so that it touches the nut -B-.

• The inner part -F- of the assembly tool and assembly bell -D- must be on the same level.

-- Place the sealing flange on the front side on a clean level surface.

• Do not turn the sensor wheel or remove it from the sealing flange.

-- Press the sealing lip support ring -1- downward in direction of -arrow- until it rests on the level surface.

• The sealing lip support ring upper edge -1- and the front edge of the sealing flange -2- must be flush -arrows-.

• The sealing flange must lie flat on the assembly tool.

-- Remove the knurled bolts -H- from the sealing flange -1-.

TIP:

Only the two knurled bolts shown in the illustration can be installed.

-- Push the sealing flange and the sealing lip support ring -2- onto the surface of the :T50010  while tightening.

-- This way the locating pin can no longer slide out of the sensor wheel hole.

-- Make sure the sensor wheel remains fixed inside the assembly tool when installing the sealing flange.

Secure the :T50010  with the Sealing Flange -1- on the Crankshaft Flange:

• The crankshaft flange must be free of oil and grease.
• The engine is at "TDC".

-- Install the nut -B- up to the end of the threaded spindle.

-- Press the threaded spindle on the :T50010  in the direction of -arrow- until the nut -B- touches the assembly bell -D-.

-- Align the flattened side of the assembly bell with the oil pan side sealing surface of the cylinder block.

-- Secure the :T50010  together with the sealing flange -2- on the crankshaft flange -1-.

-- To do this insert the hex socket bolts -E- to approximately five threads on the crankshaft flange with a hex socket wrench -3-.

-- Push the guide pin -C- in the crankshaft flange.

-- Install two M6 x 35 bolts -1- into the cylinder block to guide the sealing flange -2-.

-- Slide the assembly bell -D- in the direction of -arrow- by hand until the sealing lip support ring -2- touches the crankshaft flange -1-.

-- Check if the guide pin -C- is seated correctly in the crankshaft hole. Thereby the sensor wheel is retained in the final installation position.

-- Install both hex socket bolts from the :T50010  with the hex socket wrench -3- hand-tight.

-- Install the nut -B- far enough onto the threaded spindle by hand until it touches the assembly bell -D-.

-- Tighten the :T50010  nut -B- to 35 Nm.

• After tightening the nut to 35 Nm, a minimal air gap must still be present between the cylinder block -2- and the sealing flange -1-.
