Replacing the camshaft housing/removing and installing the camshaft (OHC) (Opel Kadett D)

Attention: The camshaft is installed by WIG. When installing this shaft in engines with numbers up to:

• 13N-814741
• 13S-814742
• 16N-17702
• 16S-95245

an additional oil channel is made in the camshaft housing (in factory conditions). Other engines have this channel. If the camshaft is replaced, then the levers are also replaced (catalog number 640579) and the oil is changed. Oil "SF" I5W-40 is poured in and replaced after 1000 km. All sliding surfaces of the levers and camshaft are coated with MoS2 grease (OPEL 1948565).

Removal

Remove the cylinder head, see p. 1.5.



Place the camshaft housing on two wooden blocks and remove the camshaft housing cover.



Unscrew the camshaft wheel, holding the camshaft with a wrench to prevent it from turning.





There are flats for a wrench between the intake cam of the 3rd cylinder and the bearing, See the figure below.



Unscrew the ignition distributor from the camshaft housing.



Where available, unscrew the fuel pump.



Remove the camshaft limiter plate.



Remove the camshaft back from the crankcase.



Pry and remove the oil seal from the crankcase.

Installation

Attention: For engines of type 13S-, 16SH, if a new camshaft is installed, the starter automatic cover should be replaced and the carburetor starter automatic should be adjusted.

After installing the WIG camshaft, it must first be run in for 4 minutes in 4 stages at variable speeds in the range between 3000 and 1500 rpm:

• Stage 1 - 1 min. at 2000 rpm.
• Stage 2 - 1 min. at 1500 rpm.
• Stage 3 - 1 min. at 3000 rpm.
• Stage 4 - 1 min at 2000 rpm.

Attention: Running-in is mandatory.

Wash all assembly parts in gasoline. Clean mating surfaces.

Before assembly, carefully coat all sliding surfaces of the levers and camshaft with MoS ₂ grease.

Place the crankcase on wooden blocks.



Insert the camshaft together with the limiter plate into the crankcase.



Secure the plate.



Install the ignition distributor. Make sure that the groove on the distributor shaft points to the marking on the distributor housing.
