Wear of an axis of yokes
|
|
Using V blocks and the dial indicator, check wear. If wear exceeds admissible norms, replace an axis of yokes. Standards of wear of an axis of yokes — 0.20 mm (0.008 inches). |
Gap between a yoke and an axis of yokes
|
|
Using a micrometer and a kruglomer, measure diameter of an axis of yokes and internal diameter of a yoke. The difference between two indicators makes a gap between a yoke and an axis which norms are specified. If norms are exceeded, replace an axis or a yoke, or both. |
Internal diameter of a yoke
norm: 15.996 – 16.014 mm (0.6298 – 0.6304 inches)
Diameter of an axis of yokes
norm: 15.969 – 15.984 mm (0.6287 – 0.6292 inches)
Gap between a yoke and an axis of yokes
norm: 0.012 – 0.045 mm (0.0005 – 0.0017 inches)
limit: 0.09 mm (0.0035 inches)
Wear of a cam
|
|
Using micromeasures, measure cam height. If the measured height is lower than norm, replace a cam-shaft. |

|
Wear of a cam-shaft
|
|
Place a cam-shaft between two "V" blocks, and measure wear, using the dial indicator. If wear surpasses norms, replace a cam-shaft. Standard of wear of a cam-shaft — 0.10 mm (0.0039 inches). |
Wear of a neck of a cam-shaft
|
|
|
|
Check necks of a cam-shaft and cases of a cam-shaft regarding corrosion, scratches, wear or damage. If some malfunction is found, replace a cam-shaft or a head of the cylinder with a case. Never replace a cylinder head without replacement of a case.
|
Check a gap, using plaster plaster solution.
This procedure is as follows.
Wash up a case and necks of a cam-shaft.
Establish a cam-shaft on a cylinder head.
Put a part of plaster plaster solution on the full width of a neck of a cam-shaft (parallel to a cam-shaft).
Establish a cam-shaft case, having addressed item 7 of the procedure of installation.
|
|
Fix cam-shaft case bolts in such order as it is specified in the drawing in the small portions until they are completely fastened to the specified rotating moment. The rotating inhaling moment: a bolt of a case of a cam-shaft (a) — 11 N • m (1.1 kg-m, 8.0 pound on foot).
|
|
|
Do not rotate a cam-shaft while plaster plaster solution lies. |
|
|
Remove a case and, using a large-scale ruler (2) on the surface of plaster plaster solution (1), measure width of plaster plaster solution in the widest place.
Cam-shaft neck gap:
norm: 0.040 – 0.082 mm (0.0016 – 0.0032 inches)
limit: 0.12 mm (0.0047 inches)
|
|
|
If the measured gap of a neck of a cam-shaft goes beyond norms, measure diameter of the chiseled opening of a neck (case) and external diameter of a neck of a cam-shaft. Replace a cam-shaft or knot of a head of the cylinder depending on where the divergence with norms is more.
Diameter of the chiseled cam-shaft neck opening
norm: 28.000 – 28.021 mm (1.1024 – 1.1031 inches)
external diameter of a neck of a cam-shaft
norm: 27.939 – 27.960 mm (1.1000 – 1.1007 inches)
