Installation

Wipe with surface cleaner:

camshaft oil seal housing in the cylinder head,
mating surfaces of the camshaft oil seal.

Attention!

Do not scrape the mating surfaces of aluminum parts, as any damage to the mating surface may result in fuel leaks.

To ensure a seal, the mating surfaces must be clean, dry and free of oil (don't touch them with your fingers).

Parts that must be replaced:

Front camshaft oil seal.
Camshaft toothed pulley fastening nut.
Timing pulley mounting stud for camshaft (in case of turning away).

Screw the stud (12) of the device into the camshaft.

Install a new oil seal onto the camshaft.

Note: For supplied oil seals installed on the protective cover:

do not remove the camshaft oil seal from the protective cover,

install the casing together with the seal on the camshaft,

push the protective cover towards the cylinder head until the camshaft oil seal and the cylinder head touch,

install the oil seal on the camshaft in accordance with the instructions below.

1 - Initial installation of the camshaft oil seal

Replace the cap (13) and flange nut (14) of the device.

Tighten the flange nut until the cap contacts the cylinder head.

2 - Second installation of the camshaft oil seal

Depending on the circumstances, the spare parts include seals (15) with a spacer (16) among other parts.

Note: The spacer (17) is used to install the gasket (18) and is used together with the tool (19).

Note: The spacer (17) is used to install the gasket (18) and is used together with the tool (19).
