Is the OEM spares List Right?

[Lordbob]

 Hi All

Finished Stripping down the cylinder head and gave it a good clean and found the part No 67-25. Some time ago I bought an OEM spares list manual thinking that this would be the bible for the renovation project, so out of curiosity I checked the spares list only to find that the listed number in the book was  67-24. This fills me with doubt now that the book is different to what I actually have particular for ordering spares.............................. or am I over reacting.

Cheers Bob

G'day Bob.
The casting/forging number is one away from the part number.

Thanks Muskrat

So i understand does that mean that the part number starts from the list number and then as each head is produced the number increases ?
(Does that sound thick?)

Have a good one

Cheers

It means the raw casting has one number and the finish machined part has the next. The second part is made from the first.
Does that make sense?
