All parts are cleaned and oil rings, locking plates and gaskets replaced.
The oil pump clearance is still within specification (inside 8/100, outside 8/100) and can be reused.
All parts need to rebuild the oil pump
Below the oil pump before and after the restoration process.
The oil sump is one of the last parts which will close the lower part of engine block. Today I tried to mount the oil seal ring at the rear cover and found out that this part should be installed just before the crankshaft is installed. After measuring all parts a came to the conclusion that it should work if;
The advantage is that it will always be possible to remove it again 🙂 The oil seal ring, which consists of two halves, is shown in the picture below.
All parts for rebuilding the oil sump
Lower engine block almost finished
When all oil sump parts are mounted the lower engine block looks almost complete. Only the oil cleaner, crank shaft damper and engine brackets are missing on this photo. I still have to decide what the next assembly parts will be!
Because my car was missing the starter, I bough one several years ago on ebay.
Although it is still looking in good shape I decided to take it apart to see if there are any problems inside.
The bush on the drive end side has some play (0.12mm) but it is not clear to me what is allowed. On the commutator end the play is only (0.05mm) Based on the original bush ID measurements it makes no sens to replace them, the difference is in the outside diameter of the axle. Because the axle, on the places where the bushes are located, looks normal and not worn, I will reused the available bushes.

Parts needed to rebuild the starter
As can be seen on the above picture the armature just looks like new. The length of the brushes are still in good condition with a length of 0,51″ or 13.0mm. (a new one measures 0.53″ or 13.5mm)
After everything has been put together again. the starter motor has been mounted onto the bell housing.
First everything has been cleaned (some steel and aluminium parts are glass bead blasted)
The oil seal and gaskets are replace with fresh ones.
All sprockets still look fine (all teeth still have a the flat surface on the top)
All parts needed to install the timing gear
Front engine without the timing gear
In the below picture the timing gear is installed completely. Also the timing gear cover and dynamo adjustment bracket is mounted. The Engine is now ready to receive the engine head.
The position where the water pump will be mounted, with 9 bolts, is clearly visible now.
The water pump, in this photo located between fan and front part of the engine, will be restored completely. The cooling capacity of these cars is not very over engineered so to keep the engine cool the water pomp need to be in top condition.
My first idea was to reuse the impeller, originally they have 4 blades, but removing them is a difficult job. Because the impeller is made of cast-iron and pressed unto the bearing axle it is almost impossible to remove them with breaking. Secondly I could not find the correct water sealing ring.
So I decided to buy a water pomp repair kit (SBS7272) with:

After the impeller and carrier for the pulley are pressed onto the bearing axle the water pump can be mounted onto the front side of the engine.
