Removal of a cranked shaft

Removal of a cranked shaft probably only from the engine taken from the car. It is meant that a flywheel/privodnoj a disk, a pulley of a cranked shaft, газораспределительный belts/chains with gear wheels/asterisks, the pallet картера, маслозаборник, the oil pump, the bridge of covers of radical bearings a cast crosspiece / balancing assemblage/maslootrazhatelnaja a plate (depending on a complete set) and shatunno-piston groups are already dismantled (the Part of Procedure of repair of petrol engines SOHC without their extraction from the car, Procedure of repair of petrol engines DOHC without their extraction from the car or Procedure of repair of diesel engines without their extraction from the car see).

PERFORMANCE ORDER

Before to start extraction of a cranked shaft from the engine, measure its size axial люфта. Fix a measuring instrument циферблатного type on the block to coaxially cranked shaft, having rested it плунжер against a cheek of one of cranks or in an end face of a pin of a shaft Measurement of size axial люфта a cranked shaft with the help циферблатного a measuring instrument плунжерного type Push a cranked shaft against the stop back and null the device indicator. Now push a shaft in an opposite direction and consider the measuring instrument indication. The size of a free wheeling of a shaft in a longitudinal direction also is its axial люфт. Compare result of measurement to requirements of Specifications in the Head Engines. If люфт exceeds the maximum admissible value, check up on presence of signs of excessive deterioration persistent surfaces of a shaft. In the absence of obvious signs of deterioration, installation of new persistent washers usually helps to correct a situation. At absence near at hand циферблатного a measuring instrument it is possible to take advantage usual щупом лезвийного type. Accurately shift a shaft against the stop forward on the engine, then define size of the formed backlash between a cheek of a crank and a half ring of the persistent combined loose leaf of the third radical bearing, densely having planted in it of a corresponding thickness an edge () щупа Alternatively axial люфт a shaft can be measured with the help щупа лезвийного type (the paragraph text see) In a diagonal order, in stages (on 1/4 turns for the approach) ослабьте bolts of fastening of covers of radical bearings so that there was a possibility of their reversing manually. Depending on necessity put on covers of radical bearings of a cranked shaft identification marks (take advantage кернером or a marker). On the majority of engines on manufacture covers of all bearings with 1 on 5 in ascending order from outside drive ГРМ are marked. Cautiously обстучите covers of bearings a hammer with soft brisk also remove them from the engine block. In case of need take advantage of bolts as levers. Track, that at dismantle of covers there were no lost loose leaves of radical bearings enclosed in them. Cautiously take a cranked shaft from the engine, - in view of relevancy of weight of assemblage it will be reasonable to secure with the help of the assistant. Track, that loose leaves of radical bearings remained in the beds in the block and covers. Establish covers on the regular places on the block, and by hand tighten fixing bolts.
