Order of dismantling of the engine

It is the simplest to make dismantling of the engine at the portable assembly stand. Such stand can usually cheap be rented in a workshop of car service or special rental center. Before installing the engine on the stand it is necessary to remove from it a flywheel / a driving disk.

If an opportunity to use the stand is absent, it is possible to make dismantling of the engine after installation it on wooden blocks directly on half of the working platform. Observe extreme care not to overturn the engine on a floor during such dismantling.

If you decided to get and install the restored engine, first of all it is necessary to remove with old all hinged units and the service equipment - they have to be then are postponed for the new block - as though you were going to start capital repairs of the old engine. Here enter:

  • The generator with arms
  • Components of systems of decrease in toxicity of the fulfilled gases
  • Distributor, candle wires and spark plugs
  • Thermostat and cover of a casing
  • Water pump
  • Components of system of injection of fuel
  • Inlet pipeline and final collector(s)
  • Oil filter
  • Engine support
  • Assembly of coupling and flywheel / driving disk

At removal from the engine of hinged units and external components pay close attention to details of their installation which can be useful and important at their transfer on the new / restored block. Remember the adjusting provision of laying, epiploons, remote plugs, pins, arms, washers, bolts and other fine details.

If you are going to make installation of the reduced set of the block (see the Section Options of restoration of the engine), then the head (i) of cylinders, the pallet of a case and the oil pump have to be removed from the old engine.

If carrying out complete capital repairs is planned, the engine has to be disassembled and from it all internal components are taken. Adhere to the following order of removal of internal components of the engine:

  • Cover (and) head(s) of cylinders
  • Inlet pipeline and final collector(s)
  • Yokes and bars of pushers
  • Hydraulic pushers of valves
  • Head (i) of cylinders
  • Cover of the drive of the gas-distributing mechanism (chain)
  • Distributive chain with asterisks
  • Camshaft
  • Case pallet
  • Oil pump
  • Conrod and piston groups
  • Bent shaft and radical bearings

Before dismantling of the engine and performing procedures of its capital repairs make sure available the listed below components (see also lists of tools provided in the Section Engine Assembly Order after completion of its capital repairs):

  • Standard set of the metalwork tool
  • Set of small cardboard or plastic boxes for storage of components
  • Pro-masonry scraper
  • Vertical drill for removal of step wear of the top part of cylinders
  • Stripper of a damper of tortional fluctuations
  • Micrometers
  • Telescopic nutromer
  • Dial measuring instrument of plunger type
  • The tool for compression of valvate springs
  • Hon for processing of mirrors of cylinders
  • The tool for a clearing of flutes of piston rings
  • Electric drill
  • Set lerok and taps
  • Wire brushes
  • Brushes (brushes) for a clearing of oil galleries
  • Solvent
