Procedure
- Transmission removed
-- Remove the flywheel. Refer to FLYWHEEL, REMOVING AND INSTALLING .
-- Remove the intermediate plate -1- from the alignment sleeves -arrows A-.
-- Guide the intermediate plate -1- upward.
-- While doing so, remove the retaining tab -arrow B- for the intermediate plate -1- from the opening behind the sealing flange.
-- Position the engine in the "TDC position for cylinder 1". Refer to VALVE TIMING, CHECKING .
-- Remove the oil pan lower section. Refer to OIL PAN LOWER SECTION, REMOVING AND INSTALLING .
-- Remove the oil pan upper section. Refer to OIL PAN UPPER SECTION, REMOVING AND INSTALLING .
-- Remove the Engine Speed Sensor -G28-. Refer to Engine Speed Sensor -G28-, REMOVING AND INSTALLING .
-- Remove the bolts -arrows- for the sealing flange -1-.
-- To press out, install three M6 x 35 bolts -arrows- in the sealing flange -1-.
The sealing flange -1- is pressed from the crankshaft -3- together with the sensor wheel -2-.
-- Tighten the bolts alternating a maximum 1 /2 turn each in the sealing flange.
-- Remove the sealing flange -1- together with the sensor wheel -2-.
Sealing Flange with Sensor Wheel, Installing
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 -1- retains the installation position via being located on the locating pin of the : T10134 . Refer to SEALING FLANGE, REMOVING AND INSTALLING, TRANSMISSION SIDE - Locating Pin .
The sealing flange and seal are one unit and may only be replaced together with the sensor wheel.
The : T10134 retains the installation position to the crankshaft via a guide pin, which is guided into the hole of the crankshaft. Refer to SEALING FLANGE, REMOVING AND INSTALLING, TRANSMISSION SIDE - Guide Pin for Gasoline Engines (Red Handle) .
Installing the : T10134 .
A - Tension Surface
B - Nut
C - Assembly Bell
D - Locating Pin
E - Hex Socket Bolt (Quantity: 2)
F - Guide Pin for Gasoline Engines (Red Handle)
G - Guide Pin for Diesel Engines (Black Handle)
H - Knurled Bolts (Quantity: 3)
I - Inner Panel
Sealing Flange with Sensor Wheel, Securing on : T10134 :
-- Install the nut -B- just up to the tension surface -A- on the threaded spindle.
-- Tension the : T10134 in a vise -1- by the tension surface -A- on the threaded spindle.
-- Push the assembly bell -C- downwards so that it touches the nut -B-.
- The inner part of the assembly tool and assembly bell must be on the same level.
-- If equipped, remove the securing clip -arrow- from the new sealing flange.
Do not turn the sensor wheel or remove it from the sealing flange.
-- Place the sealing flange on the front side on a clean level surface.
-- Press the sealing lip support ring -1- downward in direction of -arrow- until it rests on the level surface.
- Sealing lip support ring upper edge -1- and the front edge of the sealing flange -2- must be flush -arrows-.
- Position the sealing flange -1- with the front side on the : T10134 so that the locating pin -D- sits in the hole -3- on the sensor wheel -2-.
- The sealing flange must lie flat on the assembly tool.
-- Remove the knurled bolts -H- from the sealing flange -1-.
-- Push the sealing flange -1- and the sealing lip support ring -2- while tightening on the surface of the : T10134 .
-- 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 : T10134 with the Sealing Flange -1- on the Crankshaft Flange
- The crankshaft flange must be free of oil and grease.
- The engine is at "TDC". Refer to VALVE TIMING, CHECKING .
-- Install the nut -B- up to the end of the threaded spindle.
-- Press the threaded spindle on the : T10134 in direction of -arrow- until the nut -B- touches the assembly bell -C-.
-- Align the flattened side of the assembly bell with the oil pan side sealing surface of the cylinder block.
-- Secure the : T10134 together with the sealing flange -1- on the crankshaft flange -2-.
-- To do this insert the hex socket bolts -E- to approximately five threads on the crankshaft flange with a hex socket wrench.
-- Insert the gasoline engine guide pins (red handle) -F- in the crankshaft flange.
-- Install two M6 x 35 bolts -2- into the cylinder block to guide the sealing flange -1-.
: T10134 , Attaching to Crankshaft Flange
-- Slide the assembly bell -C- in direction of -arrow- by hand until the sealing lip support ring -1- touches the crankshaft flange -2-.
-- Check if the guide pin for gasoline engines (red handle) -F- is seated correctly in the crankshaft hole. Thereby the sensor wheel is retained in the final installation position.
The guide pin for diesel engines (black handle) must not be inserted into the threaded hole in the crankshaft.
-- Tighten both hex socket bolts on the assembly tool hand-tight.
-- Install the nut -B- far enough onto the threaded spindle by hand until it touches the assembly bell -C-.
Installing the Sensor Wheel on the Crankshaft Flange with the : T10134 :
-- Tighten the nut -B- for the : T10134 to 35 Nm.
- After tightening the nut to 35 Nm, a minimal air gap must still be present between the cylinder block and the sealing flange -1-.
