the portions between the oil seal retainer and main bear-
ing cap.
17. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while mov-
ing the rod back and forth.

If using a standard bearing, replace it with one having the
same number. If the number of the bearing cannot be de-
termined, select the correct bearing by adding together
the numbers imprinted on the cylinder block and crank-
shaft, then selecting the bearing with the same number as
the total. There are 5 sizes of standard bearings, marked
º1º, º2º, º3º, º4º and º5º accordingly.

INSPECTION
1. CLEAN CYLINDER BLOCK
(a) Remove the gasket material.
(b) Using a gasket scraper, remove all the gasket material
from the top surface of the cylinder block.
(c) Clean the cylinder block.
(d) Using a soft brush and solvent, thoroughly clean the cylin-
der block.

FLATNESS
Using a precision straight edge and feeler gauge, measure the
surfaces contacting the cylinder head gasket for warpage.
Maximum warpage: 0.05 mm (0.0020 in.)
If warpage is greater than maximum, replace the cylinder block.
3. INSPECT CYLINDER FOR VERTICAL SCRATCHES
Visually check the cylinder for vertical scratches.
If deep scratches are present, replace the cylinder block.
4. INSPECT CYLINDER BORE DIAMETER
HINT:
There are 3 sizes of the standard cylinder bore diameter,
marked º1º, º2º and º3º accordingly. The mark is stamped on the
top of the cylinder block.
