Removal of a cranked shaft

Removal of a cranked shaft possibly only from the engine taken from the car. It is meant that a flywheel / a driving disk, a cogwheel of a cranked shaft, a gas-distributing belt, the case pallet, a maslozabornik, the oil pump, a maslootrazhatel and (on B18B1 engines) shatunno-piston assemblies are already dismantled. Before removal of a cranked shaft it is also necessary to otboltit and separate from the block of cylinders the holder of a back epiploon.


 PERFORMANCE ORDER

1. Before starting extraction of a cranked shaft from the engine, measure the size of its axial side play. Fix the DTI measuring instrument on the block to coaxially cranked shaft, having rested its plunger against a cheek of one of cranks or a pin end face (see an accompanying illustration) the last.


Covers of radical bearings and their connecting bridge have to remain on the places, and their fixture will tighten with the demanded effort.


2. Push a cranked shaft against the stop back and nullify the device indicator. Now push a shaft in an opposite direction and consider the indication of the measuring instrument. The size of a free wheeling of a shaft in the longitudinal direction is also its axial side play. Compare result of measurement to requirements of Specifications. If the side play exceeds the maximum admissible value, check persistent surfaces of a shaft for existence of signs of excessive wear. In the absence of obvious signs of wear, installation of new persistent washers usually helps to correct a situation.

3. In the absence of near at hand dial measuring instrument it is possible to use the ordinary probe of lezviyny type. Accurately shift a shaft against the stop forward on the engine, then determine the size of the formed gap between a cheek of a crank and a forward wall of the persistent (fourth) radical bearing, having densely put in it the corresponding thickness a probe edge(s) (see an accompanying illustration).

4a. Besides serial number on covers marking in the form of cast shooters is usually provided. On correctly established covers of the shooter has to specify in the direction of a GRM drive belt. In stages (on 1/4 turns for approach) weaken bolts of fastening of covers of radical bearings and/or their connecting bridge so that there was a possibility of their reversing manually.

4b. On the Civic models check covers of radical bearings for existence on them adjusting marking. In case of need put marking independently by means of a center punch.

4c. On the Integra models check covers of radical bearings for existence on them adjusting marking. Covers have to be numbered consistently in the direction in front back on the engine (see an accompanying illustration).

5. Uncover radical bearings or assembly of their bridge. On the Integra models accurately tap the remained covers a hammer with soft brisk for the purpose of their separation from the engine block. In case of need use as levers fixing bolts. Try not to drop inserts.
6. Carefully take a cranked shaft from the engine (use the help of the assistant). Track that inserts of radical bearings remained in the beds in the block and covers. Establish covers on the block, then by hand tighten bolts of their fastening.
