Folksvagen Sharan/Sharan repair>> Engine VR6>> Cranked shaft and radical bearings>> Check of a cranked shaft
Check up a cranked shaft, carrying out following operations:
- Examine a cranked shaft. Cracks in any place of a cranked shaft are not supposed. On the surfaces interfaced to working edges of consolidations, scratches, забоины and risks are not supposed;
- Make exact measurements of necks radical and шатунных bearings. At their repair it is possible перешлифовывать to three times with reduction of diameter. After that repair loose leaves of the increased thickness are established;
- Clamp a cranked shaft between holders of a lathe (or establish extreme radical necks on two prisms) and check up the indicator palpation on a radical neck of an average support. Palpation should not exceed 0,06 mm, otherwise it is necessary to replace a shaft;
- Measure backlashes in radical and шатунных bearings, for what:

Fig. 83. The Installation site of a plastic wire for backlash measurement in radical or шатунном bearings





- Carefully clear working surfaces of loose leaves and a corresponding neck and put a piece of a plastic wire on a neck surface (fig. 83);
- Establish on a neck a rod with a cover or a cover of the radical bearing, depending on a kind of a checked neck, and tighten nuts or fastening bolts. Nuts шатунных bolts tighten the moment 30 Нм, and bolts of fastening of covers of radical bearings the moment 30 Нм;

- Uncover and on a scale of the measuring ruler entering into complete set Plastigage on flattening, in the widest place of a plastic wire (fig. 84), define backlash size;
- If a backlash less limiting these loose leaves can be used again. At a backlash, большем 0,1 mm, replace on these necks loose leaves new. If necks of a cranked shaft are worn out and ground till the repair size loose leaves replace repair (the increased thickness).
