Message The grades for the mains were pretty straight forward but am a little confused on the rods.

If someone can check my work:

Main bearings:

Front half:

Rear half:

From front to rear:

Front crank lobe(first half):

Front crank lobe(second half):

So if I understand the FAQ correctly:

F1001
+F1110
=F2111

So I should order:
1st(front): Grade 2 = 12207-30P02
2nd: Grade 1 = 12207-30P21
3rd: Grade 1 = 12207-30P21
4th(rear): Grade 1 = 12263-30P01

For the rods:

First off, my rods were not numbered 1 through 6. From front to rear they were numbered 1,2,3,6,5,2. Does this mean this engine has had some rods replaced at some point or is it normal to not have rods numbered 1 through 6?

From front to rear:

Ok, for the numbers on the rods regarding bearing:

All of the rods except the rear most rod had these markings:

The rear or last rod:

The rear rod has a 0 for the rod and a 1 for the cap

rodF000000
capF000001

And this is where I am a bit confused.

From the rear crank lobe:

First half looks like 111111 but i am thinking they might actually be zero's since the pairs of 1's are so close. (didnt capture the third pair of 1's but they are there:

And then there is a 1 0:

And finally one more 1:


This shows the spacing:

11___11___11___1___0___1

Am I correct in thinking the 1's that are paired together are supposed to be zero's?

if so:

cap F000001
+F000101
=F000102

So for the caps I should order:
Grade 0 = 12111-31P00
Grade 0 = 12111-31P00
Grade 0 = 12111-31P00
Grade 1 = 12111-31P01
Grade 0 = 12111-31P00
Grade 2 = 12111-31P02

rod F000000
+F000101
=F000101


So for the rods I should order:
Grade 0 = 12111-31P00
Grade 0 = 12111-31P00
Grade 0 = 12111-31P00
Grade 1 = 12111-31P01
Grade 0 = 12111-31P00
Grade 1 = 12111-31P01
