Engine and engine auxiliaries repair

We installed delivered engine onto the assembling rig for inspection and assembling operations.

After inspection oil sump was attached to the block using corrosion-resistant fastenings.

Corrosion-resistant fastenings were used attaching restored engine block side covers.

Tachometer drive gear was assembled using new bearings and restored components.

Tachometer drive was installed onto the engine block. Note – timing pointer is completely missing. It is required for engine tuning before it starts!

Restored fuel pump with drive mechanism was installed onto the engine.

Using corrosion-protected fastenings filter housing was attached to the block.

Restored plate with carburettor control linkage pivot was attached to the block.

We assembled and attached restored thermostat unit.

Broken pivot was improperly welded to the attachment bracket. To repair it we cut off previous weld and painted repaired part after welding.

We disassembled or inspection both heater units.

Cardboard housing was damaged.

We restored functionality of cardboard housing.

Recovered housing was painted for assembling.

Heater valves were not operable so we completely disassembled radiators for detailed tests.

After cleaning we conducted pressure tests of both heater radiators.

Radiator was damaged and leaking so after cleaning it was sent for core replacing.

Heater fan motor as disassembled for restoration.

We reconstructed for unknown reason shortened water pump outlet.

Broken handle was soldered to the dipstick breather.

None of delivered exhaust brackets was usable.

We reconstructed exhaust bracket for our project.

Carburettors were partly disassembled and cleaned in ultrasonic bath.

For restoration we completely disassembled both delivered carburettors.

Each and any part was inspected and cleaned.

For restoration we disassembled intermediate pipes.

Surfaces of the flanges had been seriously worn out and we had to machine these surfaces to achieve adequate sealing.

Restored alternator and water pump were installed onto the engine.

We machined worn out surfaces of the intermediate pipes.

Machined intermediate pipes were assembled into assembling unit using renovated components.

We restored exhaust manifold.

Restored manifold and intermediate pipes were attached to the engine.

We replaced core of the cooling radiator and tested it for the leakage.

We repaired and tested heating system radiators.

After successful passing of the leakage tests radiators were painted.

We assembled restored heating system air valves.

Certain components were painted in specific colour.

We received yellow-galvanized parts for assembling of Solexes.

We used restored components for assembling of the distributor.

Ignition system components were attached to the engine.

One stud for attachment of clutch control mechanism was damaged, another one was missing completely.

We exerted damaged stud and placed order at supplier.

We bought missing intermediate starter motor attachment piece.

Unfortunately it did not fit to our starter motor so we had to machine inner diameter.

Restored alternator and starter motor were attached to the engine.

We installed prepared engine onto our test rig.

For tests we installed onto rig also restored cooling radiator and all other components of cooling system.

We used new diaphragms and gaskets for assembling of carburettors.

We prepared carburettors for installation.

Restored carburettors were installed onto the engine and connected to control system.

Fuel return pipe was broken.

We restored before installation fuel return pipe.

Fuel supply system was installed onto the engine.

All electrical appliances were connected together for tests.

Heating system components also were installed for tests.

Restored gauges were installed and connected to other systems for tests.

Already first cranking revealed serious problem hidden into supplied for installation engine. Coolant leakage through exhaust outlet and pressure building into the cooling system signalled about possible damage of engine head gasket or faulty engine head.

Removed all ancillaries we found that leakage has occurred in the combustion chamber of the 3^rd cylinder. We had to remove engine head for further investigation.

We found corroded hole of around 3 mm into the combustion chamber of the 3^rd cylinder. We had to disassemble engine head completely to investigate possibility save this valuable part of the engine.

Engine block had also un-grinded corrosion damages on the top surface though those were not a reason this time for given problem.

We machined head after restoration and prepared it for installation.

We assembled motor on the test bench once again.

Motor and ancillaries were installed on the test bench joined together all systems.

We started reborn engine and successfully completed first run-in tests.
