3.1.2.9.2. Check коленвала

Check axial люфта

PERFORMANCE ORDER
1. Axial люфт it is checked before removal коленвала from the engine and can freely rotate in radical bearings.
2. Axial люфт it is checked with the help стрелочного the indicator. Displace коленвал to the full aside and establish an indicator scale on a zero. Displace коленвал in an opposite side and consider the indicator indication. Result compare to the standard. If люфт exceeds norm replacement of persistent half rings is required.
3. In the absence of the indicator axial люфт it is possible to check up щупом. Displace коленвал to the full towards a flywheel, then measure люфт, inserting щупы into a backlash between a cheek коленвала about 4th шатунной necks and a persistent half ring near to 3rd radical bearing.

Condition check

PERFORMANCE ORDER
1. Wash out коленвал solvent and dry. Carefully clean lubricant channels inside коленвала.
2. Check up presence on шатунных necks of traces of non-uniform deterioration, cracks, задиров and питтинга (poles).
3. Deterioration шатунной necks is accompanied by distinct metal knock on the working engine (it is especially well listened by pressing a pedal throttle заслонки at movement with small speed) and appreciable pressure drop of oil.
4. Deterioration of radical bearings is accompanied by strong vibration of the engine and a deaf roaring sound which accrues with increase in turns of the engine, and also appreciable pressure drop of oil.
5. Check up a roughness of necks коленвала, having spent on them a finger. Any roughness (which it is shown simultaneously with obvious signs of deterioration radical and шатунных bearings) specifies in necessity of repolishing of necks коленвала or its replacements.
6. Check up palpation коленвала in the central part, having established коленвал in призматические support. If palpation exceeds norm коленвал it is necessary to replace.
7. If necks коленвала перешлифовывались remove agnails round lubricant apertures.
8. Measure diameter radical and шатунных necks and compare results to the standard. Define ovality of necks for what measure diameter in several points on a neck circle. Check up конусность, having measured diameter about opposite cheeks of necks. Compare the received results to the standard.
9. Check up a condition of condensed necks коленвала. If on these necks there is the deep flute formed in a place of working edges of an epiploon consult at the expert as it is required either repair or replacement коленвала.
10. Two repair sizes for radical bearings (with reduction of diameter on 0,25 and on 0,5 mm) and for шатунных bearings (0,08, 0,12 and 0,25 mm) are provided three repair sizes. If on sale there are repair loose leaves, and deterioration of necks коленвала exceeds standard so that the further repair is impossible, it is expedient to get repaired коленвал and to establish repair bearings. About that what actions to undertake further consult in service of car-care centre or at the expert.
