Check
Crankshaft
Wear of the crankshaft
|
|
By means of the tsiferblatny indicator measure wear on a neck in the center. Slowly rotate the crankshaft. If wear exceeds limit rates, replace the crankshaft. Limit of wear of the crankshaft: 0.06 mm (0.0023 inches). |
Gap of the persistent bearing of the crankshaft
|
|
|
|
- Measure this gap when the crankshaft is regularly in the block of cylinders, i.e. when the persistent bearing (1) and covers of a pin of bearings on a place.
|
|
|
- Use a tsiferblatny measuring instrument to take readings of a deviation in the axial direction of the crankshaft. If the deviation falls outside the limits norms, replace the persistent bearing on new the standard size or the bigger size to receive a standard gap.
- Gap of the persistent bearing of the crankshaft
- norm: 0.11-0.31 mm (0.0044 – 0.0122 inches)
- limit: 0.38 mm (0.0149 inches)
- Thickness of the persistent bearing of the crankshaft
- norm: 2.47 mm – 2.52 mm (0.0973 – 0.0992 inches)
- Repair size (0.125 mm (0.0049 inches)): 2.533-2.583 mm (0.0998 – 0.1016 inches)
|

|
Ellipsnost and bias (non-uniform wear) crankshaft necks
|
|
The difference speaks about non-uniform wear of a neck of the crankshaft in diameter of cross-section section or along its length (or both that, and another). This difference if that is, is determined by indications a micromeasure. If one of necks is strongly damaged or if the general non-uniform wear, in that plan as it was explained above, falls outside the limits norm, переточите or replace the crankshaft. Limit of an ellipsnost and bias of a neck of the crankshaft: 0.01 mm (0.0004 inches). |
Crankshaft bearings
General information
Crankshaft bearings 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 differing from each other by the admission.
|
|
The top half of the 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 of the crankshaft the arrow and number is stamped. At installation of each cover of the bearing to the block of cylinders send to the shooter towards a pulley of the crankshaft 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 bearings about an ulceration, scratches, wear or damage. If any defects are found, replace the top and bottom halves. Never replace one half, without having replaced other half. |
Gap of bearings of the crankshaft
|
|
- Check a gap by means of plaster solution, having executed the following procedure.
- Remove covers of bearings.
- Clean bearings and crankshaft necks.
|
|
- Put a part of plaster solution (1) for full width of the bearing (parallel to the crankshaft) on a neck, bypassing oil openings.
|
|
|
- Establish covers of bearings as it was shown above, and evenly tighten bolts of covers by the specified rotating moment. The cover of the bearing should be fastened according to technical requirements to provide the correct indications of a gap. The rotating moment of an inhaling: a bolt of a cover of the bearing of the crankshaft (and) — 54 N • m (5.4 kg-m, 39.0 pound on foot).
|
|
|
Do not turn the crankshaft with plaster solution inside. |
|
|
- Uncover and by means of a ruler (2) measure width on a plaster covering (1) in the widest point. If the gap 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 gap. If it did not occur, it is necessary переточить a crankshaft neck in order 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 a gap repeatedly.
- Gap of the bearing of the crankshaft
- norm: 0.02-0.04 mm (0.0008 – 0.0015 inches)
- limit: 0.060 mm (0.0023 inches)
|
|
|
Choice of bearings of the crankshaft
Standard bearing
|
|
- If the bearing in failure condition or if the gap of the bearing falls outside the limits norm, choose the new standard bearing according to the following procedure, and establish it.
- At replacement of the crankshaft or the block of cylinders for any reason choose new standard bearings to establish them according to numbers printed on the new crankshaft, and/or the letters printed on the interfaced surface of the new block of cylinders.
|
|
|
- At first check diameter of a neck by means of the following procedure. On cheeks of the crankshaft of cylinders No. 2 and No. 3 five figures are printed. Three types of figures («1», «2» and «3») represent the next diameters of necks.
