a) Using a dial indicator, measure the inside diameter of the camshaft bearings.
Inner diameter of bearings (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) By subtracting the previously obtained values of the journal diameters (see above) from the obtained values of the internal diameters of the bearings, determine the value of the radial clearance in the camshaft bearings.
- Nominal clearance - 0.025 -0.111 mm
- Maximum gap - 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. Note: Each bearing has its own outside diameter.
a) Remove the plug.
b) Using a puller, remove the camshaft bearings.
c) 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.
d) Check the clearance in the camshaft bearings.
d) Install the plug.
Apply sealant to the cylinder block bore surface and hammer the plug until its surface is flush with the edge of the cylinder block.
