Mitsubishi Galant

1. Whereas during the running cycle pistons do not reach the top cut of the cylinder, in the end of their course on a mirror of cylinders the step which presence stirs to extraction of shatunno-piston assemblages is formed and can be the reason of damage of new pistons at their installation in the engine.
2. Some types of the vertical drills applied to removal of step deterioration of cylinders are issued, all of them are among concerning inexpensive tools.
3. Turn a cranked shaft so that the piston of the corresponding cylinder has fallen to the bottom position.
4. Cover the bottom of the piston with a rags protective layer
5. Prepare a vertical drill and, adhering to instructions of manufacturers of the tool, process the top part of the cylinder, having removed with it step deterioration.

Try not to be overzealous and not to damage a mirror of cylinders in its working part!

6. Take a vertical drill, rags and the sawdust formed as a result of processing.
7. Operating in a similar manner, remove step deterioration from mirrors of all cylinders.

1. Establish the engine on the assembly stand or a strong workbench. Alternatively lay the unit on a garage floor on pair wooden blocks (a surface interfaced to transmission downwards). Engine position should provide an easy approach to fixture of covers of the bottom heads of rods and possibility проворачивания a cranked shaft. All provided by a design of the unit of a cover should be removed from the engine.
2. Remove from the engine components of drive ГРМ and a head of cylinders. Remove the pallet картера and маслозаборный knot. In case of need remove a drive of the oil pump, balancing and auxiliary shaft.
3. Remove traces of step deterioration in the top part of cylinders (see above).
4. Turn the engine so that direct access to a cranked shaft has opened. With the help чертилки or кернера mark rods according to their accessory the to cylinders. Similarly mark also covers of radical bearings.
5. Again turn the engine, - this time the first cylinders upwards. Turn a cranked shaft so that the piston of the first cylinder has appeared in the bottom part of the course. Release fixture and remove a cover of the bottom head of a rod of the first cylinder (track that the loose leaf шатунного the bearing remained in a cover).

6. Pull on fixing hairpins pieces of a fuel hose, having provided with that protection of a neck of a shaft and a mirror of cylinders against damage to extraction process шатунной assemblages.

7. The wooden handle of a hammer push a rod upwards approximately on 25 mm and take from bed in its bottom head the top loose leaf of the bearing.

8. Continue to tap cautiously assemblage upwards until from the cylinder piston rings will not be liberated. In case of resistance occurrence immediately stop percussion of assemblage and make sure of completeness of removal of traces of step deterioration in the top part of a mirror of the cylinder!

9. Manually definitively take shatunno-piston assemblage from the block. Enclose bearing loose leaves in bed, establish into place a cover of the bottom head of a rod, slightly having tightened fixture.
10. Operating in a similar manner, take from the block the remained shatunno-piston assemblages.

At service of V-shaped engines assemblages from of the same kind cylinders at first are taken, then the engine turns over upwards the second row and the remained assemblages are taken.

12. At the given stage the cranked shaft should appear the only thing remaining in the block a component. In stages in regular intervals ослабьте fixture also remove covers of radical bearings (with the loose leaves enclosed in them).
13. Cautiously take from the beds in the block a cranked shaft.
14. Make careful cleaning of all removed components. If be not going to start immediately engine assemblage, lay the block in a pure polyethylene package.

1. During check of a condition of components of the block of the engine some special tools be required. Into number of such tools enter:

· Two or three micrometers for measurement of diameters of pistons and necks of a cranked shaft;
· Циферблатный a measuring instrument плунжерного type;
· the Machine tool for an estimation of degree of deformation of rods.
2. At absence near at hand necessary toolkit it is necessary to charge performance of check of a condition of components to experts of car-care centre.
3. Attentively examine the block on presence in it of cracks and other mechanical damages. Ways of revealing of latent defects are described in Section Regenerative repair of a head of the cylinders, devoted to check of a condition of a head of cylinders. Will charge most correctly performance of check of a condition of moulding of the block to experts of car-care centre.

1. Check up beds of radical bearings in the block and covers on presence of traces of an overheat, задиров and agnails and other mechanical damages. In case of need give the block in проточку, or make its replacement. Easy defects can be removed by means of a file with a small tooth.
2. Check up centering of beds of bearings in the block by means of a planeness measuring instrument, having laid last along an axis of a lining of a cranked shaft, - in case of revealing люфта or backlashe
