- Then unscrew by hand and remove together with oil filter insert.
- Remove oil filter insert -2- from oil filter housing center tube -4-.
Sealing ring, removing
Warning!
The oil filter housing sealing ring -3- must be replaced each time the oil filter insert is changed -2- or every other time the oil filter housing is loosened.
The sealing ring is equipped with a so-called "service flag" -A-.
The sealing ring can be gripped at the "service flag" -A- with a suitable tool and then removed from the seal groove.
- Remove sealing ring -1- from oil filter housing seal groove -2- by pulling sealing ring out with needle-nose pliers -3- on the "service flag" -arrow-.
Sealing ring, installing
- Lubricate sealing ring -3-.
- Lay sealing ring in oil filter housing seal groove so service flag -A- is aligned toward top.
- Press sealing ring into seal groove and check whether ring contacts entire groove evenly by feeling above sealing ring with finger -arrows-.
Oil filter insert, installing
- Press new oil filter insert -2- onto oil filter housing center tube -4- as far as stop.
Oil filter housing, installing
- Install oil filter housing -4- with new sealing ring -3- and new oil filter insert -2- by hand until almost on oil filter housing stop -1-.
- Tighten oil filter housing -2- to 25 Nm.
- Install dust cap -arrow- hand-tight in oil filter housing.
Replacing oil filter (Diesel engines)
Removing
Note: Observe waste disposal regulations! Oil new O-rings before installation.
- Loosen sealing cap -arrow- e.g. using ring wrench AF 36 or using socket insert AF 36 T10125.
Note: Loosen cap before draining/extracting so that engine oil can flow out of filter housing.
- Clean sealing surfaces at cap and at oil filter housing.
Installing
- Install oil filter -3-
- Replace O-rings -2 and 4-.
