Installation of shatunno-piston assemblies and check of size of working gaps in shatunny bearings of a cranked shaft

Try not to touch surfaces of new inserts barehanded in order to avoid undesirable contact of bearings with always with the traces of oil and chemically aggressive substances which are present on fingers.


1. Before installation of shatunno-piston assemblies of a wall of cylinders have to be carefully wiped, from their upper edges traces of step wear are completely removed and is chamfered. It is meant that the cranked shaft is already installed on the regular place in the block.
2. Uncover the lower head of a rod of the piston of the first cylinder (be verified with the factory or put in the course of dismantle tags). Take inserts of the old bearing from a head of a rod and its cover and carefully wipe their beds pure nevorsyashcheysya rags.
3. Wipe a back of a new top insert and put it to bed the bearing in a rod head. Track that the directing uvula of an insert got to a reciprocal flute in a rod. At all not to a zastukivayta an insert in a bed a hammer. Grease with nothing the bearing at this stage.
4. Wipe a back of the second insert and lay it in a cover of the lower head of a rod. Again track that the uvula got to a reciprocal groove. Do not apply any greasing – extremely important that the interfaced surfaces of the bearing and a rod remained absolutely pure and dry.

5. Arrange piston rings locks as it is shown on an accompanying illustration.

Have no locks of rings to coaxially piston finger AT ALL, or perpendicular to its axis.

6. Pull on bolts of fastening of a cover of the lower head of a rod pieces of an old fuel hose for protection of a mirror of the cylinder and a neck of a cranked shaft against casual damages to process of installation of shatunno-piston assembly.
7. Grease the piston and piston rings with pure motive oil and put on the piston a tool mandrel for a staving of rings. Leave a skirt of the piston acting from a tool mandrel approximately on 6.4 mm for free gas station it in the cylinder. Rings have to be pressed out aflush with the forming piston surface.
8. Turn a cranked shaft so that the neck of the first crank appeared in situation NMT. Oil motive a mirror of the first cylinder.

9. Having developed assembly by a tag in the form of deepening or an arrow on the piston bottom on the engine forward (see an accompanying illustration), accurately fill a rod in the first cylinder of the block. Bring a piston skirt to the cylinder, having densely pressed to a block surface bottom edge of a mandrel of the tool for a staving of rings.

10. Tap the upper edge of a mandrel for a guarantee of dense pressing it to the block on all perimeter of bottom edge.

11. Accurately tapping on the piston bottom with the wooden handle of a hammer (see an accompanying illustration), enter the piston in the cylinder, at the same time directing the lower head of a rod on a neck of a crank of a cranked shaft. Piston rings can unexpectedly jump out from under a tool mandrel therefore constantly watch density of its pressing to the block. Act without hurrying, at emergence of the slightest resistance immediately stop a piston zastukivaniye. Find out the reason of jamming and eliminate it. Do not make at all attempts to push the piston in the cylinder by force, is can lead to its mechanical damage or destruction of piston rings.

Check of a working gap of the shatunny bearing


1. After introduction of shatunno-piston assembly to the engine, before final installation of a cover of the lower head of a rod, it is necessary to check a working gap of the shatunny bearing of a cranked shaft.

2. Cut off a piece of the calibrated plastic wire from the measuring Plastigage set, length width of an insert of the shatunny bearing are slightly shorter, and lay it along the first shatunny neck of a cranked shaft, parallel to an axis of the last (see an accompanying illustration).

3. Wipe a bearing surface in a cover of the lower head of a rod, remove protective hoses from fixing bolts and establish a cover on a rod. Track that the tag on a cover was turned in the same party, as a tag on a rod.
4. Previously having oiled, screw nuts of fastening of a cover and tighten them with the demanded effort. In order to avoid jamming of a key, use a thin-walled face head. At emergence of signs of jamming of a key between a nut and a rod, slightly raise a head and continue a tightening. Do not allow a provorachivaniye of a cranked shaft in the course of a tightening of fixture of a cover of the shatunny bearing.

Do not allow a provorachivaniye of a cranked shaft in the course of performance of all procedure.

5. Turn off nuts and carefully uncover a rod. Try not to damage the flattened-out piece of the calibrated wire.

6. On width of the flattened-out wire measured on the scale printed on packing to the Plastigage set (see an accompanying illustration), determine the size of a working gap in the bearing. Compare result of measurement to requirements of Specifications.

7. If the size of a gap exceeds the limit of admissible range before looking for inserts of other standard size, check, whether got under backs enclosed in beds in a rod and a cover of inserts dirt/oil. Once again measure diameter of a neck of a shaft. The wire flattening since one end more than from another speaks about existence of conicity of a neck.

Final installation of shatunno-piston group


1. Carefully scratch out a nail or edge of an old credit card all traces of the calibrated wire from a surface of a neck and/or the bearing.
2. Make sure of absoluteness of purity of both bearing surfaces, then evenly grease them with a thin layer of molibdensoderzhashchy assembly motive greasing. For ensuring access to a surface of the top insert it is necessary to push a little the piston in the cylinder, – do not forget to put on rod cover bolts protective hoses in order to avoid damage of a surface of a neck of a shaft. Try not to allow vyskakivaniye from the cylinder of piston rings.
3. Return a rod into place, having carefully put on it the lower head a neck of the crank, remove protective hoses from bolts, establish a cover and in two stages tighten fixing nuts with the demanded effort.
4. Repeat all procedure for the remained shatunno-piston assemblies.
5. Do not miss the following important points from attention:
   a) Watch that on backs of inserts and their bed in rods and covers dirt did not get;
   b) Watch that each assembly was established in the cylinder (even in case of installation of new components as gaps of piston rings were adjusted to concrete cylinders);
   c) Pistons have to settle down a tag/arrow on the bottom on the engine forward (towards the GRM drive);
   d) Do not forget to oil before installation of assemblies motive a mirror of cylinders;
   e) Before final installation of covers of bearings after check of working gaps in the last do not forget to grease bearings.
6. Having finished installation of shatunno-piston assemblies, check freedom of rotation of a cranked shaft, having turned it several times manually.
7. In summary it is necessary to double-check an axial side play of a cranked shaft (see Removal of shatunno-piston assemblies).
8. Compare results of measurement of an axial side play to requirements of Specifications. If the side play was in norm before dismantling of the engine and old shatunno-piston assemblies are used, no surprises should be. In case of a side play size exit out of admissible limits after replacement of rods, the last need to be removed from the engine and to give to a workshop of car service for the corresponding machining.
