Check

Коленвал

Deterioration коленвала

With the help циферблатного the indicator measure deterioration on a neck in the centre. Slowly rotate коленвал. If deterioration exceeds limit rates, replace коленвал. A deterioration limit коленвала: 0.06 mm (0.0023 inches).

Backlash of the persistent bearing коленвала

 PERFORMANCE ORDER

  1. Measure this backlash when коленвал is regularly in the block of cylinders, i.e. when the persistent bearing (1) and covers of a pin of bearings on a place.
  1. Use циферблатный a measuring instrument to take readings of a deviation in an axial direction коленвала. If the deviation falls outside the limits norms, replace the persistent bearing on new the standard size or большего the size to receive a standard backlash.
    • Backlash of the persistent bearing коленвала
      • Norm: 0.11 – 0.31 mm (0.0044 – 0.0122 inches)
      • Limit: 0.38 mm (0.0149 inches)
    • Thickness of the persistent bearing коленвала
      • Norm: 2.47 mm – 2.52 mm (0.0973 – 0.0992 inches)
    • The repair size (0.125 mm (0.0049 inches)): 2.533 – 2.583 mm (0.0998 – 0.1016 inches)

Эллипсность and a bias (non-uniform deterioration) necks коленвала

The difference speaks about non-uniform deterioration of a neck коленвала in diameter of cross-section section or along its length (or both that, and another). This difference if that is, is defined under indications a micromeasure. If one of necks is strongly damaged or if the general non-uniform deterioration, in that plan as it has been explained above, falls outside the limits norm, переточите or replace коленвала. A limit эллипсности and a neck bias коленвала: 0.01 mm (0.0004 inches).

Bearings коленвала

The general information

Bearings коленвала for repair are presented in the standard size and in the size less standard on 0.25 mm (0.0098 inches), and each of them is presented by 5 types of the bearings different from each other by the admission.

The top half of bearing (2) has a lubricant flute (3). Establish this half with a lubricant flute in the block of cylinders (1).
On each cover of the bearing коленвала the arrow and number is stamped. At installation of each cover of the bearing to the block of cylinders direct an arrow towards a pulley коленвала and establish each cover from this party towards a flywheel in ascending order numbers 1, 2, 3, 4 and 5. Fasten bolts of covers to the specified rotating moment.

Check

Check up bearings on a subject изъязвления, scratches, deterioration or damage. If any defects are found out, replace the top and bottom halves. Never replace one half, without having replaced other half.

Backlash of bearings коленвала

 PERFORMANCE ORDER

  1. Check up a backlash by means of a plaster solution, having executed the following procedure.
  2. Remove covers of bearings.
  3. Clean bearings and necks коленвала.
  1. Put a part of a plaster solution (1) for full width of the bearing (in parallel коленвалу) on a neck, bypassing oil apertures.
  1. Establish covers of bearings as it has been shown above, and in regular intervals tighten bolts of covers by the specified rotating moment. The bearing cover should be fastened according to technical requirements to provide correct indications of a backlash. The rotating moment of an inhaling: a bolt of a cover of the bearing коленвала () — 54 Н•м (5.4 kg th, 39.0 pound on foot).

Do not turn коленвал with a plaster solution inside.


  1. Uncover and by means of a ruler (2) measure width on a plaster covering (1) in the widest point. If the backlash falls outside the limits norm, replace the bearing. Always replace the top and bottom half, as a unit. The new standard bearing can create a necessary backlash. If it has not occurred, it is necessary переточить a neck коленвала that it was possible to use the bearing of the smaller size of 0.25 mm (0.009842 inches). Having chosen the new bearing, check up a backlash repeatedly.
    • Bearing backlash коленвала
      • Norm: 0.02 – 0.04 mm (0.0008 – 0.0015 inches)
      • Limit: 0.060 mm (0.0023 inches)

Choice of bearings коленвала

The standard bearing

  • If the bearing in failure condition or if the backlash of the bearing falls outside the limits norm, choose the new standard bearing according to the following procedure, and establish it.
  • At replacement коленвала or the block of cylinders for any reason choose new standard bearings to establish them according to numbers printed on new коленвале, and-or the letters printed on the interfaced surface of the new block of cylinders.
