Yamaha part number breakdown

[M.V.]

Found this while doing a little sluething for spare parts, may be handy!

I found this interesting:

1. Model Code Number Data: XX0-X000X-X0-X0
The first three digits within the general part number structure are model designation numbers.
Within this three-digit group, two numbers may be replaced with letters.
The major portion of letter substitution will occur with the second position of this three-digit
group (i.e.: 0X0-00000-00-00). This letter has no other significance other than model
identification. The model identification indicates the original model in which the part was
used, i.e.:
1A0-00000-00-00 Identifies RD 400 model
2A0-00000-00-00 Identifies XS 400 D model
3A0-00000-00-00 Identifies GS 340 model

2. Basic part number data: XX0-X000X-X0-X0
The second group of five digits is the actual parts group identification number (i.e. 11631 -
piston; 11311 - cylinder etc.). A «W» substituted in the first position of this five-digit group
(000-W0000-00-00) indicates a factory assembled kit which differs in content from the
original assembly used in production (i.e. 2M0-W0046-00-00 – Rear Break Pad Ass’y). The
first three digits of this five-digit group (000-XXX00-00-00)indicates the general sections and
areas of the models. The fourth and fifth digits of this group (000-000XX-00-00) indicates
the specific part within these general sections and areas. In the case of number overflow, a
letter will be substituted in the fifth digit position of this five-digit group (i.e. 1T4-2814A-00-
00 – Wire Tool).

So, essentially, if the 5 digits in the middle are the same, say a TRX mastercylinder part number 3GM-W2587-50(-00) & a 2003 R1 Mastercylinder part number 4SV-W2587-10-00, they should be interchangable...

I think...

The -10 & the -50 indicate that they are revisions or slightly different models though, so they may not be exact.

Well, 3GM is the code for the FZR1000 EXUP and 4SV is the code for the Thunderace. The FZR master cylinder is 5/8" and the Thunderace one is 14mm...

I think you're barking up the right tree, but the middle sequence only tells you the parts group, not the actual part. If you were in a warehouse, for example, you'd go to the 'W2587/master cylinder' section and then look for the '3GM' box for a TRX part or the '4SV' box for an R1 part.

So a google search shows a yzf 1000 RJ/c as a thundercat with bluespots??? Wouldn't this use a 14mm master cylinder???

Ah, so they could still be different parts... I make 5/8ths near enough to 16mm...

They are different parts

They are different parts

Sorry, I was a bit vague there!

First part was in relation to your statement, the second part was just mental garbage.
