Car dismantling and determination of defects

Work process

1. Car dismantling and determination of defects

Work began in January 2007. Upon beginning to dismantle the car, we concluded that in spite of the car's venerable 50 years of age, its body was still in good condition visually and technically.
The underside of the car and its sealed cavities had been treated with anti-corrosion coating and therefore there were virtually no corroded places or elements on the car's body.
During the dismantling process, we documented the condition of the car's components, the rebuilding work carried out by the previous owner, and parallel to the determination of component and system defects, we compiled a list of the components to be replaced. 

 BMW 501 1956 body before restoration

 

We began the dismantling process by removing the car's big body panels. We then dismantled the left side doors and rear wing, and removed the rear window and rear ventilation panes. All window apertures are in satisfactory condition. The rear arch had not been ravaged by rust. We found rust around the lower hinge of left side rear door. By treating this place with a sand blaster, we will be able to ascertain whether it will require welding work during the restoration process.

We removed the headlamps, engine cover and decorative front fenders. We discovered that the places where the lamps were fastened had not been affected by corrosion. The cooling system radiator is in good condition.

 

.BMW 501 1956 front dismantling process 

 

We removed both front wings. The prior anti-corrosion treatment had been carried with sufficient care and no rust had affected these body parts.

We dismantled the book section cover mechanism with number lighting. The threaded parts of screw connections are not rusty and are in good condition. We intend to order replacements for both sealing rubber parts, and to carry out polishing on the handle.

 

 

We removed the side decor fittings and running board rubbers. Over the course of time, the car's rubber components have lost their elasticity - we intend to replace these. The aluminium mounts are deformed - we are currently restoring them to their original form. If this doesn't work out, we will need to order these components from new.

 

 

The fastening bracket on the right side rear wing is slightly deformed. After treatment with a sand blaster, it will be necessary to restore them to their original form.

 

The fastening bracket on the left side rear wing is in better condition.

 

The front panel is equipped with all of the required switches, however unfortunately many of their plastic handles are blistered and will have to be replaced.

We dismantled the chromed rear bumper - it will require rechroming.

 

 

The rear left side wing was also removed. The inside of the arches has been treated with anti-corrosion resin that has protected the metal from corrosion.

 

 

 

Inspecting the car's running gear, we checked the ZF gearbox. New support cushions are required. No oil leaks are visible from the gearbox - the input and output valve glands do not need replacement.

 

 

Inspecting the clutch-gearbox connection valve with elastic compensation elements, it is evident that they have been changed quite recently and therefore they do not need to be replaced right now.

 

 

Inspecting the clutch operating cylinder, we noticed that it had an oil leak. Therefore, a set of repair gaskets is required, as well as a new feed-pipe.

 

 

The exhaust system ducts have been affected by corrosion, but even so they are still technically in working order.

 

The hand brake mechanism requires renewal of its cable protector.

 

Rear left side suspension torsion and hand brake actuator.

 

Rear right side torsion and shock absorber. The torsion bearing is in good condition without excessive free movement.

 

Rear cardan next to axle reducer. One of the four fastening screws had become unscrewed. The cardan joints and their packing glands are in good condition and do not need to be replaced.

 

16.02.2007.
During our determination of the car's defects, we ascertained that the following items were missing or needed to be replaced:
1) Door window crank handle;
2) Salon thermometer (attached to the ceiling);
3) Radio panel.

We continue to dismantle the car's running gear and salon equipment.

 

We began to empty the engine cavity by disconnecting the engine systems and removing the engine together with the clutch block. When the engine had been dismantled, we inspected the front section of the car's frame and ascertained that it is in good condition. The partition wall separating the salon from the engine cavity is corroded in a few places which had not received anti-corrosion treatment, but these defects are superficial and surface treatment will be all that is required to rectify the damage.

 

 

After removing the engine, we removed the remaining component, tubes and wire bundles from the engine cavity, documenting their mutual positioning and condition prior to restoration.

 

 

 

The main brake and clutch cylinders were removed first. They will be taken apart later so that we can determine whether there are any defects.

 

 

 

The side doors, front and rear wings, windows and components in the engine compartment have been removed from the body frame. After careful inspection, we conclude that welding work will not be required - individual existing corrosion zones will have to be cleaned and prepared for the painting of the surface.

 

 

 

We checked the dismantled components separately. The front wings do not require welding or smoothing work - they can be prepared for painting.

 

 

Engine cover and rear wings. We found small signs of rust in rear wing lamp fastening places - additional surface treatment will be required here before painting.

 

 

Upon removing the boot partition upholstery, it becomes clear that it has been infiltrated by water. There are no rusted-through components here either, but the damaged zones will need to be cleaned of rust and have to undergo anti-corrosion treatment.

 

 

We carried out a detailed inspection of the condition of the doors. Thanks to the anti-corrosion treatment performed on the internal surfaces, their overall condition is satisfactory - only the outer sealing rubber bolting flanges of the doors are rusty. It is possible that welding work will not be required, but we will only be able to determine this after the surfaces have been cleaned.

 

The legacy of corrosion on the sealing rubber bolting flanges of the doors.

 

 

Corrosion has also affected the door hinge brackets, particularly the lower ones, but it's superficial and welding work will not be necessary here.

 

 

19.02.2007
We removed all sealing rubber and internal door mechanisms - the rubber was worn, but everything else can be renovated.

 

The sealing rubber has lost its properties and will have to be replaced.

 

The insides of the doors are in relatively good condition

 

 

Corrosion is superficial and can be relatively easily removed prior to painting.

 

 

 

An inspection of boot compartment cover did not reveal any corroded places and it can be delivered to be prepared for painting.

 

 

20.02.2007.
We continue the process of taking apart the dismantled door components and assessing their technical condition.

 

In determining the defects of the chrome-lined front door window regulators, we decided that the door glass regulators, as the internal and external door glass rubber would have to be replaced.

 

 

The ventilation pane opening mechanism is very rusty. It will have to be taken apart and after the rust has been removed, a galvanized coating will have to be applied to its components.

 

 

The glass regulator bracket is not corroded. The aluminium regulators are in good condition.

 

27.02.2007. We studied the dismantled engine components to further determine any defects.
Upon visual inspection, it was immediately clear that the following items would require replacement:
1) Engine cushions;
2) Outflow receptacle gaskets;
3) Water pump gaskets;
4) Cooling system tubes;
5) Ignition distributor cover;
6) Sparkplug leads;

The cooling system will have to be washed - upon disconnecting the cooling system tubes, it is evident that the system has been infiltrated by an indeterminable brown coloured fluid.

 

Inspection of carburettor shows that the following items will have to be replaced:
1) all gaskets;
2) needle;
3) accelerator pump plunger.

 

 

We examined the electrical system's components. The front window cleaning mechanism drive motor is in working order and will be renovated.

 

 

 

Inspecting the fuel tank and its level gauge sensor, we decided that the gasket would have to be replaced.

 

 

We completely dismantled the electrical system and documented the positioning and connections of the wiring.

 

We began to dismantle the salon upholstery.

 

Upon removing the salon lining parts, we documented their positioning and type of fastening, because the decorative salon parts were completely worn out and would have to be replaced with brand new parts.

 

 

Front panel. Unfastened electrical installation wires were freely hanging in the lower section.

 

 

The décor of the chromed measuring instruments is in poor condition and will have to be rechromed.

 

 

The existing measuring instruments and their combinations in the panel were taken apart concurrently documenting the positioning and order of their connections.

 

Salon front panel with switches, relay switches and their decorative handles.

Decorative plastic handles were removed.

Upon removing the salon's decorative lining panels, we documented their condition and type of fastening. Front passenger side decorative lining.

Lower part of the frontal frame on the driver's side. Upon removing the decorative lining and door rubber, an area affected by corrosion becomes visible.

A new electrical device for the left side lamps will have to be produced, because the existing one is damaged.

The reverse lamp wires have been repaired previously, and they will have to be replaced.

The right side wires will also have to be replaced.

We took the steering wheel apart - a new sound signal button will be required.

Upon removing the speedometer panel, we concluded that the following items would have to be replaced:
1) Speedometer cables;
2) Speedometer cable packing rings.

In a few places, the previous owner had created new wire bundles - it will be necessary to restore the original electrical system.

The main front headlamp connection is in good condition.

The front right side headlamp wires will have to be replaced.

The front right side headlamp wires will have to be replaced.

No significant damage was discovered when we determined the damage of the steering wheel mechanism - regulation will be required when installing it.

The window cleaning liquid vessel is missing.

The previous owner has modified the brake equipment by installing an additional relay for the brake signal lamps - the original construction will have to be renovated during the restoration process.

Dismantling the electrical system, we carefully documented the positioning of its components and their mutual connections.

04.04.2007
We carried out an assessment of the salon lining components. The car's seat frames are in satisfactory condition, but they will have to be recovered. The internal stitching of the doors was not torn, but it was worn and dirty. New lining parts will be produced.

The crank handle of the window opening mechanism was deformed and could not be repaired; it will have to be replaced.

11.05.2007
The door hinges are still in good condition; i.e. without excessive free movement caused by wear and tear, therefore they will be treated with a sandblaster, primed and painted black.
