Corsa C

Crankshaft, Check Alignment (Z 18 XE)

  Measure

1.   Condition: engine dismantled
2.   Insert 10 crankshaft bearing shells
•   Observe identification and allocation
•   Note position of axial bearing
•   In cylinder block, crankshaft bearing cap
3.   Insert crankshaft
•   Into cylinder block
4.   Attach 5 crankshaft bearing covers
•   Observe identification and allocation
•   Tighten 10 bolts
Note:   Bolts do not have to be replaced when checking crankshaft alignment
– Tightening torque 50 Nm + 45° + 15°
Object Number: 2411365 Size: DEFAULT


5.   Attach MKM-571-B
•   Install MKM-571-B in bracket
•   Attach bracket to transmission side of cylinder block
Object Number: 2377841 Size: DEFAULT


6.   Adjust MKM-571-B
•   Attach probe to crankshaft flange
•   Attach MKM-571-B under pre-tension
•   Set MKM-571-B to "0"
7.   Measure crankshaft end play
•   Move crankshaft
•   Read off test value
Note:   Repeat measurement several times. For permitted crankshaft play see "Technical Data - Crank Drive, Cylinder Block"
8.   Remove MKM-571-B
9.   Remove 5 crankshaft bearing covers
•   Unscrew 10 bolts
10.   Attach MKM-571-B
•   Attach to cylinder block with bracket
11.   Adjust MKM-571-B
•   Attach probe to crankshaft bearing journal
•   Attach MKM-571-B under pre-tension
•   Set MKM-571-B to "0"
12.   Measure crankshaft concentricity deviation
•   Turn crankshaft evenly
•   Read off test value
Note:   For permitted crankshaft concentricity deviation see "Technical Data - Crank Drive, Cylinder Block"
Object Number: 2377840 Size: DEFAULT


13.   Remove MKM-571-B
14.   Remove crankshaft
15.   Measure diameter of 5 crankshaft bearing journals
•   Measure at 2 places per bearing using micrometer gauge
Note:   Note dimensions - if a dimension is outside the permitted tolerance, the crankshaft must be ground or replaced.
Object Number: 2387881 Size: DEFAULT


16.   Attach 5 crankshaft bearing covers
•   Observe identification and allocation
•   Tighten 10 bolts
Note:   Bolts do not have to be replaced when checking crankshaft alignment.
– Tightening torque 50 Nm + 45° + 15°
17.   Set up internal measuring instrument
•   Fit appropriate probe tip to internal measuring instrument
– Fit MKM-571-B to internal measuring instrument with approx. 1 mm of pre-tension
•   Slide internal measuring instrument between micrometer gauge test surfaces
•   Determine indicator turning point
– Oscillate internal measuring instrument between test surfaces
– Set MKM-571-B to "0" at turning point
Object Number: 2417763 Size: DEFAULT


18.   Measure diameter of 10 crankshaft bearing bores
•   Determine turning point in 2 places (I+II) per bearing
– Oscillate internal measuring instrument in crankshaft bearing hole
•   Note dimensions
Object Number: 2404420 Size: DEFAULT


19.   Calculate crankshaft bearing play (5 times)
Note:   The crankshaft bearing play is calculated on the basis of the difference between the crankshaft bearing bore and crankshaft bearing journal diameters. For permitted crankshaft bearing play see "Technical Data - crank drive, cylinder block"
20.   Remove 5 crankshaft bearing covers
•   Unscrew 10 bolts
21.   Remove10 crankshaft bearing shells
22.   Measure diameter of 4 con-rod journals
•   Measure in 2 places (I, II) using micrometer gauge
Note:   Note dimensions - if a dimension is outside the permitted tolerance, the crankshaft must be ground or replaced.
Object Number: 2418016 Size: DEFAULT


23.   Insert 8 con-rod bearing shells
•   Observe identification and allocation
•   In con-rod, con-rod bearing cap
24.   Attach 4 con-rod bearing caps
Important:   The mating surfaces of the cod-rods and con-rod bearing caps form an individual fit and must not be damaged or interchanged. Do not lay on mating surfaces.
•   Observe identification and allocation
•   Tighten 8 bolts
Note:   Bolts do not have to be replaced when measuring con-rod bearing play.
– Tightening torque 25 Nm + 30°
25.   Reconfigure internal measuring instrument
•   Remove probe tip
•   Fit appropriate probe tip to internal measuring instrument
– Fit MKM-571-B to internal measuring instrument with approx. 1 mm of pre-tension
•   Slide internal measuring instrument between micrometer gauge test surfaces
•   Determine indicator turning point
– Oscillate internal measuring instrument between test surfaces
– Set MKM-571-B to "0" at turning point
26.   Measure diameter of 4 con-rod bearing bores
•   Determine turning point in 2 places (I, II)
– Oscillate internal probe in con-rod bearing bore
•   Note dimensions
Object Number: 2404422 Size: DEFAULT


27.   Calculate con-rod bearing play (4 times)
Note:   The con-rod bearing play is calculated on the basis of the difference between the con-rod bearing bore and con-rod bearing journal diameters. For permitted con-rod bearing play see "Technical Data - crank drive, cylinder block"
28.   Remove 4 con-rod bearing caps
