Order of dismantling of the engine

It is simplest to make engine dismantling at the portable assembly stand. Such stand usually cheaply can be rented in a workshop of car-care center or special point of hire. Before establishing the engine on the stand from it it is necessary to remove a flywheel / a driving disk.

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

If you decided to get and establish the restored engine, first of all it is necessary to remove with old all hinged units and auxiliaries - they should be then are transferred on the new block - as though you were going to start major maintenance 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 casing cover
  • Water pump
  • Components of system of injection of fuel
  • Inlet pipeline and final collector (ы)
  • 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 appear useful and important at their transfer on new / the 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), should be removed from the old engine a head (and) cylinders, the pallet of a case and the oil pump.

If carrying out complete major maintenance is planned, the engine should 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) heads (ok) cylinders
  • Inlet pipeline and final collector (ы)
  • Yokes and bars of pushers
  • Hydraulic pushers of valves
  • Head (and) cylinders
  • Cover of a drive of the gas-distributing mechanism (chain)
  • Distributive chain with asterisks
  • Camshaft
  • Case pallet
  • Oil pump
  • Shatunno-porshnevye groups
  • Cranked shaft and radical bearings

Before the beginning of dismantling of the engine and performance of procedures of its major maintenance make sure available listed below components (see also lists of tools provided in the Section the Assembly order of the engine after completion of its major maintenance):

  • Standard set of the metalwork tool
  • Set of small cardboard or plastic boxes for storage of components
  • Prokladochny scraper
  • Vertical drill for removal of step wear of the top part of cylinders
  • Stripper of a damper of krutilny fluctuations
  • Micrometers
  • Telescopic nutromer
  • Tsiferblatny measuring instrument of plunzherny type
  • The tool for compression of klapanny springs
  • Hon for processing of mirrors of cylinders
  • The tool for pro-cleaning of flutes of piston rings
  • Electrodrill
  • Set lerok and taps
  • Wire brushes
  • Brushes (ершики) for pro-cleaning of oil galleries
  • Solvent
