4.15. An order of dismantling of the engine by preparation it to capital repairs


Scheme of an arrangement of hinged units


Design of the block of cylinders

 

It is the simplest to carry out dismantling of the engine, having installed it on the portable assembly stand. Such adaptation can always be borrowed rather cheap in a workshop of car service. Before fixing the engine at the stand, it is necessary to remove from it a flywheel / a driving disk.

If an opportunity to use the stand is absent, dismantling should be made, having placed the engine on a strong workbench, or having reliably arranged it on a firm floor of a garage. During the work without stand you watch that the engine incidentally did not overturn.

If it is planned to make replacement of the engine by restored, remove with old all hinged units and external components and transfer them to the replaceable block. In number such, subject to shift, components enter (see the illustrations Scheme of an Arrangement of Hinged Units and Design of the Block of Cylinders):

At removal from the old engine of external components try to remember characteristics of their installation. Fix landing provisions of laying, epiploons, remote rings and plugs, pins, arms, washers, bolts and other fine details in a notebook.

At the choice of the scheme with use of the reduced set of the block consisting of the block of cylinders with established in it by a bent shaft and conrod and piston groups remove from the old unit also a head of cylinders, the pallet of a case and the oil pump (alternative versions of schemes of performance of capital repairs — see. Alternative versions of schemes of recovery repair of the engine).

When carrying out complete capital repairs of the old unit, make its dismantling and take all internal components. The optimum order of implementation of the procedure of dismantling of the engine is given below:

Before starting dismantling of the engine, prepare the following materials, tools and details (see also Assembly order of the engine):
