Removal of shatunno-piston assemblies

 PERFORMANCE ORDER

Before starting extraction from the engine of shatunno-piston assemblies, it is necessary to remove a head(s) of cylinders, the pallet of a case and the oil pump with a maslozaborny tube.

1. By means of a special vertical drill completely remove traces of step wear from the top part of cylinders - act according to the instructions of the manufacturer attached to a vertical drill. The step is formed on piston stroke border, approximately in 6.4 mm under the top cut of the cylinder due to mechanical production of metal and a nagaroobrazovaniye, it is possible to determine its existence to the touch by a finger nail. Attempts of extraction of shatunno-piston groups without removal of step development are fraught with damage of pistons.

2. Having finished preparation of cylinders, turn the engine upside down so that the cranked shaft appeared from above.
3. For the purpose of ensuring access to rods remove a maslootrazhatelny plate.

On 4-cylinder engines of a cover of radical bearings are united by the general bridge which then fastens to the block of cylinders. Check of an axial side play of a shaft on such engines has to be made before removal of this bridge (see the Section Removal of a Cranked Shaft) (and a maslootrazhatelny plate). The axial side play of rods on the necks can be defined through openings in the bridge. For removal of shatunny assemblies the bridge needs to be dismantled.

4. Before removing rods from a cranked shaft, estimate the size of their axial side play on necks of the last. Densely enter an edge(s) of the measuring probe into a gap between a sidewall of the lower head of a rod and a cheek of a crank, having completely chosen a rod side play on a shaft neck. Total thickness of the picked-up probe edges will also equal to the size of an axial side play of a rod. Compare result of the taken measurement to requirements of Specifications. If the size of an axial side play exceeds limit admissible value, this rod is subject to replacement. The axial side play of a new rod, or old on new to a shaft, can appear less than the lower admissible limit, in this case the rod can be pierced - consult with specialists of car service. Serially check all remained rods.

5. Make sure available on the lower heads of rods and their covers of identification tags of belonging to the cylinder - do not mix number of a rod with marking of the size of the shatunny bearing,

in case of need put tags independently by means of a small center punch.

6. In stages (on 1/2 turns for approach) weaken nuts of fastening of covers of the lower heads of rods so that there was a possibility of their otvorachivaniye manually. Uncover the first rod together with the bearing insert placed in it - try not to drop the last.

On 4-cylinder engines removal of shatunno-piston assemblies can be made only after dismantle of the bridge of covers of radical bearings (see the Section Removal of a Cranked Shaft).

7. Take an insert from the lower head of a rod, then, having rested the wooden handle of a hammer against a bearing bed in the lower head, push out shatunno-piston assembly at the top of the cylinder at the top of the block. At emergence of resistance immediately stop extraction of assembly and check completeness of removal of step wear in the top part of the cylinder.
8. In a similar manner take the remained shatunno-piston assemblies from the engine.

Installation of the rod which is subject to extraction coaxially to the cylinder is made by the corresponding provorachivaniye of a cranked shaft, - start extraction only after the rod is located strictly parallel to a cylinder axis!

9. In order to avoid casual mechanical damage of bearings and loss of components, establish into place inserts and fix covers of bearings on the lower heads of the rods, having by hand tightened nuts.
10. Do not remove pistons from rods (for more details see the Section Check of a Condition of Components of Shatunno-piston Group).
