Note

♦

The sealing flange with PTFE oil seal is fitted with a sealing lip

support ring. This support ring acts as an assembly sleeve and

must not be removed before installation.

rotated out of position after removal from packaging.

♦

The sender wheel is held in its installation position by a locat‐

ing pin on the assembly tool -T10134- .

♦

The sealing flange and oil seal are one unit and must always

be replaced together with the sender wheel.

♦

The assembly tool -T10134- is held in the correct position rel‐

ative to the crankshaft by a guide pin which is inserted into a

hole in the crankshaft.

of flats -A-.

– Clamp assembly tool -T10134- in a vice on tightening flats

-A- of threaded spindle.

– Press assembly housing -C- downwards so that it lies on hex‐

agon nut -arrow-.

• Inner part of assembly device and assembly housing must

align (be level) with each other.

– Remove the securing clip -arrow- from new sealing flange.

Note

The sender wheel must not be taken out of the sealing flange or

rotated out of position.

• The locating hole -A- on the sender wheel -C- must align with

sealing flange must align -arrows-.

– Place front side of sealing flange on assembly tool -T10134- ,

so that locating pin -B- can be inserted in hole -A- in sender

wheel.

• Ensure the sealing flange lies flat on the assembly tool.

– Press the sealing flange and sealing lip support ring -B- onto

the surface of the assembly tool -T10134- while tightening the

3 knurled screws -A- so that the locating pin will not slip out of

the hole in the sender wheel.

• Ensure that the sender wheel remains fixed on the assembly

• Crankshaft flange must be free of oil or grease.
• Engine is at “TDC” position.
– Screw hexagon nut -B- to end of threaded spindle.
– Press the threaded spindle of assembly tool -T10134- in di‐

rection of -arrow- until the hexagon nut -B- lies on the assem‐

bly housing -A-.

– Position flat edge of assembly housing towards sealing sur‐

face for sump on cylinder block.

– Secure assembly tool -T10134- to crankshaft flange by screw‐

ing hexagon socket head bolts -A- approx. 5 threads into

crankshaft flange.

– Screw two bolts M7×35 mm -item A- into cylinder block to

guide sealing flange.

C - Securing assembly tool -T10134- onto crankshaft flange:
– Press the assembly housing -C- by hand in the direction of the

-arrow- until the sealing lip support ring -B- lies on the surface

of the crankshaft flange -A-.
