The main bearings are available in blue, black, brown, green,
yellow and pink of the size identification color in this order in
increments of 0.003 mm (0.0001 in).
4) Note that the oil clearance is set taking the enlarged
amount of the housing caused by crash into consideration.
The bearings are selected so that the oil clearance for the
No.1, 2, 4 and 5 journals is in the range of 0.017 – 0.041 mm
(0.0007 – 0.0016 in), and the oil clearance for the No.3
journal is in the range of 0.025 – 0.049 mm (0.0010 – 0.0019
in).
5) Check the oil clearance after installing the selected bearing
6) Align the projection of the bearing with the cutout in the
cylinder block or lower block, and install with care not to
damage the sliding surface.
• Do not determine the bearing simply by referring to the
selection table, but check the oil clearance.
• If the selection table shows two identification colors, use
a pair of the bearing of each color for the upper and lower
bearings.
