DKW KS WH

The cylinder is removed from the engine. The surface shows signs of corrosion. The indentation is small but clearly worn out.

A lot of carbon deposit was here. This engine was used with a bad oil. The cylinder ducts were plugged. One of exhaust ducts was completely blocked.

Carbon deposit and settlements have been removed. There was a lot of dust here, so the cylinder has been pressure-washed, dried and painted.

The piston was seized. The rings got stuck in grooves.

Piston has been cleaned. The lowest ring is to be replaced, at the front side it got "baked" into its groove.

If this piston is meant to be in use again, it would be best to replace all rings. The bolt in the piston is a bit too loose.

The clutch shaft shows signs of damage.

The crankcase is damaged, too, at the point where the ring is inserted to hold the shaft bearing.

The shaft was renovated some time ago. Connecting rod end without clearance. Shaft pins were polished. Oversized rolls in the bearings (13x6,07 + 2x 5,75). In one bearing there are signs of corrosion, to be removed.

All parts to be cleaned and checked.

The left crankcase was fixed once. It was welded where the ring is inserted. There are visible signs of the impact force. The engine was probably fixed after a road accident quite long ago. Later it worked for a time until it got abandoned and dried completely. It was probably the gear changer that got blocked.

The alternator is complete and shows no mechanical damage. Wire is damaged and brushes must be replaced.

The engine cover is complete, in a good condition.It needs repair at the point where the kickstarter's spring is attached.

The right engine crankcase is good.

The left engine crankcase has been repaired once. The bearings could be inserted on glue, so that the insertion ring doesn't have to work so hard.

But this crack is disturbing: it is at the point where the starter release pin should be screwed in. Here, the shock loads are expected.
