Checking the radial play of the crankshaft
1. Install the main bearing caps. If the cover is installed correctly, its tab should be offset to the left when viewed in the direction of travel (those. be on the side of the intake manifold).
2. Measure the diameter of the crankshaft hole in the cylinder block (with main bearing caps installed) in directions A, B and C.
3. Measure the diameter of the hole in direction A and write it down. Let, for example, 62.51 mm.
4. Remove the main bearing cap.
5. Measure the diameter of the main bearing journal. Let, for example, 57.95 mm.
6. Calculate clearance:
Hole diameter (62.51 mm) - Diameter of the neck of the main bearing of the crankshaft (57.35 mm) = 4.55 mm.
From this result, subtract the nominal value of the radial clearance of 0.04 mm (talk to Specifications table) and get 4.51 mm. Divide this result by 2 and get the liner thickness of 2.255 mm.
7. Select an appropriate liner thickness. For example: liner thickness 2.255 mm. As required Specifications choose an insert by color. In this case, it's a blue liner.
8. Insert the connecting rod bearings into the connecting rod cap and secure with bolts.
9. Measure diameter of the bottom head of a rod with loose leaves.
10. Measure the diameter of the connecting rod journals and determine the radial clearance in the crankshaft bearings from the measured value. Connecting rod diameter (with liners) - Diameter of the connecting rod journal = Radial clearance of the crankshaft.
Checking the axial play of the crankshaft
1. Measure the width of the crankshaft main bearing journal.
2. Determine the thickness of the end play adjuster. The thickness of the axial play adjusters varies from 2.15 to 2.40 mm in 0.05 mm increments.
3. Install end play adjusters. The oil passages must be lubricated and installed forward.
4. Measure the end play of the crankshaft and, if necessary, adjust it.
