Float chambers were covered with thick layer of residuals.

All inner cavities of fuel system contained certain amount of dirt.

We disassembled fuel filter for defect detection and repair.

Strainer of the fuel filter almost completely was clogged by dirt.

All removed steel parts and fitting were cleaned by glass beads and sent for galvanizing or painting respectively.

For detailed inspection and repair we completely disassembled filter housing.

We had to replace damaged rubber items.

For detailed inspection and repair we completely disassembled chambers of the vacuum system.

Damaged components were listed among parts to order.

For detailed inspection and repair we completely disassembled carburettors.

Still usable components of the carburettors were cleaned and painted, if appropriate.

For detailed inspection and repair we completely disassembled thermostat housing.

Respective parts after cleaning were sent to powder-coating.

For detailed inspection and repair we completely disassembled air filter housing.

We separated housing parts to weld internal cracks and fissures.

All weld seams were grinded.

After rinsing of the cooling system channels, we removed pump and additional piping from the block.

We removed old paint before block was sent to paintshop and machining.

We sent prepared block to the paintshop.

We continued disassembling of the carburettors.

All components of the carburettor control linkage we cleaned and painted.

We restored all accelerator system components.

For defects detection and repair we disassembled distributor.

There was obvious erosion of the distributor cap electrodes.

For defects detection we partly disassembled fuel pump.

It was necessary to replace just some rubber components of the fuel pump.

For defects detection we disassembled fuel tank.

Inner surface of the fuel tank was in acceptable condition.

We disassembled for restoration rocker cover with oil filler cap.

Fuel pipe connecting carburettors was leaking.

We soldered leaking fuel pipe and sent it to the galvanizing workshop.

Prepared parts of the engine and components we sent for powdercoating.

Coated parts were prepared for assembling.

We acquired new pistons and sent engine block for re-boring.

We prepared for painting engine head cover.

We completely disassembled engine head for following machining.

We installed new air filter insert.

We assembled restored air filter.

We assembled restored oil filter.

We assembled restored valve unit.

We assembled restored coolant pump.

Prepared components were shelved until assembling.

We machined surface of the engine head and reworked seats of the upper valves.

We inserted valves in valve guides for tightness test before final assembling.

After successful tightness test we continued assembling of the engine head.

We installed valve springs and inserted removed studs.

We received new genuine valves for assembling of the engine block.

We prepared new pistons for installation.

We joint pistons and connecting rods.

Arrived current parcel with parts for assembling of the engine.

We attached restored engine block to the assembling rig.

Before assembling, we opened crankshaft plugs for inspection of oil channels.

Thick layer of debris covered inner surface of the oil channels.

We carefully cleaned all oil passages in the crankshaft.

We assembled inlet manifold.

We assembled restored throttle.

We installed throttle on to the inlet manifold.

We finished preparation of the connecting rods attaching new big end bearings.

We inserted into block new pistons, valves and prepared crankshaft.

We continued assembling of the motor installing transmission gears and damper unit.

We attached to the block lubrication system components.

Motor block was furnished with head and oil sump.

We attached to the motor cooling and ignition system components.

We assembled restored control bars and leavers.

We disassembled for restoration lubrication system of the chassis.

Arrived batch with components for assembling of the engine and chassis.

For restoration, we completely disassembled Powersteering pump.

After cleaning, we discovered serious damages on external motor pipework, so we manufactured new piping.
