A) Using a lever gauge, measure the inside diameter of the camshaft bearings.
Bearing inner diameter (starting from the front):
- No. 1 - 46.500 - 46.570 mm
- No. 2 - 46.250-46.320 mm
- No. 3 - 46.000-46.070 mm
- No. 4 - 45.750 - 45.820 mm
- No. 5 - 45.500 - 45.570 mm
b) Subtracting the previously obtained values of the diameters of the necks (see above) from the obtained values of the inner diameters of the bearings, determine the amount of radial clearance in the camshaft bearings.
- Nominal clearance - 0.025 -0.111 mm
- Maximum clearance - 0.14 mm
If the clearance is greater than the maximum, replace the camshaft bearings. If necessary, regrind or replace the camshaft.
2. If necessary, replace the camshaft bearings. Attention: each bearing has its own outer diameter.
A) Remove the plug.
b) Using a puller, remove the camshaft bearings.
V) Install new camshaft bearings.
Pre-align the oil passage holes in the bearings and in the cylinder block.
Using a suitable tool, install the bearings.
G) Check the clearance in the camshaft bearings.
d) Install the plug.
Apply sealant to the bore surface of the cylinder block and tap the plug with a hammer until its surface is flush with the edge of the cylinder block.
