Repair or deep cleaning of a Soviet refrigerator Zil 64 often require complete or partial disassembling the unit. Despite the considerable age of this model, many copies continue to work properly, but over time they need to replace the seals, thermostat or compressor. The correct sequence of actions will avoid damage to fragile elements and will simplify access to internal components.
The dismantling process begins with preparing the workspace and disconnecting the device from the power supply. Refrigeration unit it weighs a lot, so for safe work you may need an assistant, especially when removing heavy metal doors. A careful study of the design before starting work will save you from unnecessary mistakes.
In this article we will consider in detail the disassembly stages, paying special attention to specific components of the model Zil 64. You will learn how to get to hidden fasteners, safely remove the door and gain access to the compressor-condensing unit without the risk of damaging the copper tubes.
Preparation for disassembly and safety precautions
The first step is to completely disconnect the refrigerator from the network and defrost it. There may remain refrigerant residual pressure inside the system, so any manipulations with the tubes are carried out only after they are completely released. If you plan to replace the compressor, make sure that you have access to a fresh portion of freon and oil filling equipment.
For the job, you will need a standard set of tools: flat-head and Phillips screwdrivers, wrenches, pliers and, possibly, a knife to carefully trim the seals. It will not be amiss to prepare a container for collecting water and a rag for wiping surfaces. Wire insulation must be checked before connecting new components.
⚠️ Attention: Before starting any work with electrical components, make sure that the plug is removed from the socket. Residual charge in capacitors can be dangerous, so do not touch the contacts immediately after disconnecting.
Arrange for sufficient lighting of the work area. Shadows can hide small fasteners or cracks in the metal. If you are working in a garage or workshop, ensure good ventilation, especially if you plan to solder pipes or work with solvents.
☑️ Preparing to disassemble Zil 64
Dismantling the door and removing shelves
For ease of access to the internal volume and reducing the weight of the structure, it is recommended to remove the door. In the model Zil 64 hinges can be hidden with decorative overlays or require unscrewing the screws from the bottom and top. Carefully remove all removable shelves and trays so that they do not interfere with manipulations with the body.
The door is held on two or three hinges that are attached to the main body. When unscrewing the top hinges, you must hold the door so that it does not fall and damage the floor or its own corners. Threaded connections Over the years of operation they could have become stuck, so use penetrating lubricant (WD-40 or analogues) in advance.
It is better to put the removed door in a safe place place, leaning against the wall, to avoid deformation of the canvas. The sealing rubber on older models often hardens and cracks. When disassembling, inspect its condition: if it is brittle, it is better to replace it immediately, while access to the fastening channel is open.
- 🔧 Unscrew the screws securing the upper and lower hinges using a suitable bit.
- 🚪 Remove the door, holding it with your second hand or asking an assistant.
- 📦 Remove all internal shelves, drawers and storage guides.
- 🧹 Clear the freed space of food debris and ice.
After removing the door, access to the inner walls of the chamber opens. It is important here not to damage evaporatorif it is built into the back wall or ceiling of the camera. Any impacts or punctures will lead to depressurization of the system.
Disassembling the internal volume and removing the ceiling
The inside of the refrigerator Zil 64 may have removable finishing elements. The lighting lamp, if provided by the design, is usually secured with latches or screws. To remove it, carefully pry the edges of the plastic diffuser with a flat screwdriver wrapped in a cloth so as not to leave scratches.
If your modification has a freezer with a separate door or an evaporator box, the process of dismantling them requires caution. The fastenings can be hidden under decorative plugs. Thermoregulator Often located inside the chamber or on the external panel, and replacing it may require partial disassembly of the internal volume.
Hidden shelf fastenings
In some modifications ZIL there are 64 shelves can be held not on standard guides, but on hidden plastic clips that need to be pressed simultaneously from both sides.
When working inside the camera, be careful about the wiring. wires can run along the walls and be secured with clips. Do not pull the wires by force - it is better to carefully snap off the latches. Electrical wiring in old refrigerators they are often made of materials that lose elasticity, so the risk of breaking the wire is high.
| Element | Type of fastening | Tool | Features |
|---|---|---|---|
| Door | Hinges with screws | Key/Screwdriver | Heavy, needs an assistant |
| Lamplight | Latch/Screw | Flat screwdriver | Fragile plastic |
| Shelves | Guides | Without tools | Remove carefully |
| Thermostat | Nut/Latch | Wrench 10-12 mm | Carefully with capillary |
Access to the compressor-condenser unit
The back of the refrigerator Zil 64 hides the main technical components. There is a compressor, a capacitor (coil) and a start-up relay located here. To access them, it is often necessary to remove the rear metal panel, which can be attached to many screws around the perimeter.
The compressor in this model is usually fixed to the frame using shock-absorbing rubber washers or springs. Before removal, it is necessary to disconnect the electrical contacts and carefully bleed the refrigerant (if the system is still sealed). Motor-compressor is a heavy unit that requires reliable fixation during dismantling.
⚠️ Attention: When removing the compressor, do not turn it over or tilt too much, as this may cause oil to enter the refrigerant circuit, which will make subsequent starting difficult.
The condenser grille is attached to the rear wall of the housing. If it is contaminated with dust and fluff, it can be carefully washed with water, having first disconnected it from the pipelines, or blown with compressed air. Heat transfer directly depends on the cleanliness of these elements.
Replacing the thermostat and electrical parts
Thermostat (temperature regulator) is one of the most frequently replaced elements. B Zil 64 it can be located inside the chamber or brought outside. To replace, you need to remove the regulator handle and unscrew the fixing nut, then carefully pull the capillary tube out of the seat.
The starting and protective relay are attached directly to the compressor housing. They are removed by simply disconnecting the block and removing it from the terminals. When installing a new relay, it is important to maintain the correct orientation (the "UP" arrow must face up), otherwise the compressor will not start or will burn out.
When working with electrical equipment, check the integrity of the wires. Old insulation can crack at the slightest bend. Contact groups should be cleaned of oxides if you plan to use old connectors, although it is better to replace them with new ones.
- ❄️ Carefully remove the sensitive element (capillary) of the thermostat from evaporator.
- 🔌 Take a photo of the wire connection diagram before disconnecting.
- 🛡️ Install a new thermostat with similar characteristics.
- 🔘 Check the operation of the contacts with a multimeter before assembly.
Assembly and initial startup
After repair work or deep cleaning, assembly is performed in the reverse order. Make sure all screws are tight, but not too tight to avoid stripping the threads in the old metal. The door is hung last, after checking the operation of the mechanisms.
The first start after replacing the compressor or breaking the tightness of the system requires evacuation and charging with freon. Without this step, the refrigerator Zil 64 will not begin to cool. If only the thermostat was changed or cleaning was carried out, it is enough to plug in the device and check the cyclic operation.
Pay attention to the level of noise and vibration during the first start-up. If the compressor hums more than usual or gurgling sounds are heard, there may be air left in the system or the amount of refrigerant is incorrectly selected. Tightness connections are a key success factor.
⚠️ Attention: After filling the system with refrigerant and turning it on for the first time, do not load food into the refrigerator immediately. Let it run idle for 1-2 hours to reach the operating mode and check the stability of the temperature.
Check the tightness of the door around the entire perimeter. If you removed the seal, make sure it fits straight into place. A loose fit will lead to the formation of ice and increased load on the compressor.
Is it possible to disassemble the ZIL 64 refrigerator alone?
Theoretically It's possible, but the door and compressor are quite heavy. It is highly recommended that you have a second person to safely remove the door and work on the rear panel to avoid personal injury or damage to the frame.
Does it need to drain the oil from the compressor during disassembly?
If you are simply removing the compressor for replacement, there is no need to drain the oil if the compressor is working properly. If the compressor burns out or you change it to a new one, the old oil from the system (if it gets into the circuit) must be removed by purging with nitrogen.
Where can I find the electrical connection diagram for ZIL 64?
The diagram is usually located on the back wall of the refrigerator or inside the chamber on a sticker. If the sticker is lost, the diagram can be found in the technical data sheet of the model or in specialized reference books on the repair of Soviet refrigeration equipment.
What to do if the hinge screws are rusty and cannot be unscrewed?
Treat the threads with penetrating lubricant (WD-40, kerosene) and leave for 15-20 minutes. Try slightly heating the metal around the screw (be careful with the enamel) or use an impact screwdriver to remove the rust from its place.
