Engine and engine auxiliaries repair

Separated engine unit was stored till detailed defects detection.

Sensitive components were cleaned by glass beads before further surface treatment - galvanizing or painting.

Engine was completely disassembled. During disassembly specific components were marked accordingly.

There were noticed serious soot deposits in the combustion chambers and on the valves. Cylinders were removed.

 There were traces of the erosion on the cylinder surfaces and soot deposits on the pistons. There were traces of the wear on the piston jackets.

Oil sump plug full with debris was signalling about hard work with no appropriate maintenance. Strainer was almost completely filled with engine mud. Similar deposits were covering whole internal surface of the engine block.

All engine components were cleaned in the washing device. Strainer again can provide some discharge capacity.

All engine components were carefully tested before further repair actions.

Cylinder heads requiring machining after cleaning were sent to the specialist workshop.

Alternator was completely disassembled for overhauling. Bearings were worn out and stator winding coil insulation was rotten and falling off. Alternator bearings were replaced and rotor collector received maintenance. New stator winding coils were installed.

Starter motor, solenoid switch and freewheeling clutch were overhauled similarly to alternator.

Carburettors were disassembled for detailed defects detection. All components were sent to ultrasonic cleaning before assembly. 

Engine heads were received from overhauling. Assembling was started using new seals, gaskets, washers. Valves were fixed into the place.

Preparing components for assembly it was discovered that rocker pivot support has a crack and it was needed to make it anew.

 Oil pump base plate was frayed. Oil pump base plate was grinded to achieve needed smoothness of the surface.

Both halves of the engine block was assembled together, new bearing shells were used. Prepared in advance pistons and heads were installed onto engine block as we proceeded further in engine assembling process.

Renovated and new engine ancillaries were installed onto the engine. Restored clutch was installed onto the engine.  

Restored engine cooling system shrouds, as well as new exhaust system components were installed onto the engine.

Chromed oil filler neck had a crack at the filling pipe junction and we used brass welding to eliminate this defect before new chrome layer was spread on.

Filter housings were chromed, but layer was damaged and those had to undergo re-chroming.

One of cam covers was missing breather pipe and, since such unit was not available as spare part, we had to manufacture exact copies of missing items. As our copy was welded into the place covers were sent for powder coating.

Restored accelerator control linkage elements were installed onto fan shroud.  

 Lid in the luggage compartment was missing one corner because of severe rust, so we hammered out missing piece and welded it into the place. Restored cam covers were received after surface galvanising.  

 We manufactured new rocker pivot support to substitute original one which was broken. Engine heads were assembled and initial clearance adjustments were carried out.

Alternator was assembled and installed onto the engine.

Missing cover plate was self fabricated and installed in the engine compartment.

Restored carburettors and fuel supply pipelines were installed onto the engine.

Received automatic carburettors heating system components were installed onto restored engine plate. Carburettors heating control thermostat was installed and adjusted as prescribed.
