Removal of shatunno-piston assemblies

Before starting extraction from the engine of shatunno-piston assemblies, it is necessary to remove a head of cylinders, the pallet of a case and the oil pump with a maslozaborny tube (see. Parts engine Repair without extraction from the car - the Civic models or engine Repair without extraction from the car - the Integra models of the present Chapter).

PERFORMANCE ORDER

1. By means of a special vertical drill completely remove traces of step wear from the top part of cylinders (see an accompanying illustration) – act according to the instructions of the manufacturer enclosed to a vertical drill. The step is formed on piston stroke border, approximately in 6.4 mm under the top cut of the cylinder at the expense of mechanical production of metal and a nagaroobrazovaniye. Attempts of extraction of shatunno-piston groups without removal of step development are fraught with damage of pistons.

2. Having finished preparation of cylinders, overturn the engine upside down so that the cranked shaft appeared from above.
3. On all engines, except В18В1, for the purpose of ensuring access to shatunny assemblies it is necessary to remove the bridge of covers of radical bearings (see. Removal of a cranked shaft).

4. Before removing rods from a cranked shaft, estimate their size axial люфта on necks of the last. Densely enter an edge (I) measuring щупа into a gap between a lateral wall of the bottom head of a rod and a crank cheek, having completely chosen люфт a rod on a shaft neck (see an accompanying illustration). The total thickness of the picked-up edges щупа also will equal to size axial люфта a rod. Compare result of the carried-out measurement to requirements of Specifications. If the size axial люфта exceeds limiting admissible value, this rod is subject to replacement. Axial люфт a new rod, or old on new to a shaft, it can appear less than the bottom admissible limit, in this case the rod can be pierced – consult with specialists of car-care center. Serially check all remained rods.

5a. Make sure available on the bottom heads of rods and their covers of identification labels of belonging to the cylinder – do not mix rod number with marking of the size of the shatunny bearing (see an accompanying illustration).

5b. In case of need put labels independently by means of a small center punch.

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

7. Pull for the ends of hairpins of fastening of a cover pieces of a fuel hose to exclude any possibility of casual injury of a neck of a shaft and a cylinder mirror in the course of extraction of shatunny assembly from the last (see an accompanying illustration).

8. Take from the bottom head of a rod the loose leaf, then, having rested the wooden handle of a hammer against a bearing bed in the bottom head, вытолкните shatunno-piston assembly at the top the cylinder outside from the engine. At resistance emergence immediately stop extraction of assembly and check completeness of removal of step wear in the top part of the cylinder.
9. In a similar manner take from the engine the remained shatunno-piston assemblies.

Installation of a rod subject to extraction coaxially to the cylinder is made by the corresponding povorachivaniye of a cranked shaft – extraction start only after the rod will be strictly located parallel to a cylinder axis!

10. In order to avoid casual mechanical damage of bearings and loss of components, establish into place loose leaves and fix covers of bearings on the bottom heads of the rods, having by hand tightened nuts.
11. Do not remove pistons from rods (for more details see. Check of a condition of components of shatunno-piston group).
