CRANKSHAFT AND CONNECTING RODS

4. Select:

• big end bearings (P

1

 ~ P

2

)

NOTE:
• The numbers 

a stamped into the crank-

shaft web and the numbers 

b on the con-

necting rods are used to determine the
replacement big end bearing sizes.

• “P

1

” ~ “P

2

” refer to the bearings shown in

the crankshaft illustration.

▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼

For example, if the connecting rod “P

1

” and

the crankshaft web “P

1

” numbers are “6”

and “2” respectively, then the bearing size
for “P

1

” is:

▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲

“P

1

” (connecting rod) – “P

1

” (crank-

shaft web) =
6 – 2 = 4 (green)

BIG END BEARING COLOR CODE

5. Measure:

• crankshaft journal diameter 

a

Out of specification 

→ Replace the crank-

shaft.
