HOW TO SELECT PISTON AND BEARING
1. "Main Bearing Selection Table" rows correspond to bearing
housing grade on rear left side of cylinder block.
• If there is a corrected stamp ma rk on the cylinder block, use it
as a correct reference.
2. Apply journal diameter grade (A) stamped on crankshaft front side to column in "Main Bearing Selection Table".
3. Find value at crossing of row and column in "Main Bearing Selection Table". CAUTION:
• There are two main bearing selecti on tables. One is for odd-numbered journals (1, 3, and 5) and
the other is for even-numbered journals (2 and 4) . Make certain to use the appropriate table. This
is due to differences in the specified clearances.
4. Apply the symbol obtained to "Main Bearing Grade Table" to select. NOTE:
• Service parts are available as a set of both upper and lower.
When Cylinder Block and Crankshaft are Reused:
1. Measure inner diameter of cylinder block main bear ing housing and outer diameter of crankshaft journal.
2. Apply measurement in above step 1 to the "Main Bearing Selection Table".
3. Follow steps 3 and 4 in "When New Cylinder Block and Crankshaft are Used".

release onto fuel tube.
ii. Insert the quick connector release (A) into quick connector (2) until sleeve (B) contacts and goes no further. Hold quick connec-
tor release on that position.

• Pull quick connector (E) ho lding position (D) as shown.
• Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth beforehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installati on/removal.
• To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
