Yanmar Part Numbers Help

[DivinaVitae]

I need help deciphering a Yanmar 4JH3E Parts List. The parts list that I have does not explain the use of the split part numbers, such as:

1 129670-42500 PUMP ASSY, WATER (1)

1-1 129670-42501 PUMP ASSY, WATER (1) R
(A=E/#22126)

1-2 129670-42510 PUMP ASSY, WATER (1) N
(A=E/#22643)


I understand the alpha notations in the far right column; and, the numeric notations when they appear. I also understand the “A” in the parenthesis indicates a specific engine within the series.

I am assuming that the “E/#XXXXX” is referring to a starting serial number for a European engine, wherein all engines above that number require the part number specified.

However, inasmuch as my engine’s serial number is lower than any number specified in the list, my assumption is questionable.

I have contacted Yanmar US and Mastry, without success. I have a number of parts that I will be ordering, so any assistance/information is greatly appreciated.

I will try to help.

I have 4JH3TE and all manuals and part number catalogs. I'm not sure exactly what you are looking for. I'm thinking there is a little bit of a language barrier. We can work through that.

Good Day Mike:

Thank you for the reply and your offer to help. My confusion is stemming from the hyphenated part numbers, for example:

Figure 27 Cooling Fresh Water Pump shows-

2 129150-42320 O-RING
2-1 129054-42320 O-RING
(A=E/#25450) ...

The Parts Legend indicates that the "A" in the parenthesis relates to my 4JH3E engine. However, thus far I have been unable to verify that the "E/#25450" relates to an "E" (European) prefixed, starting serial number to which the 2-1 part would be applicable.

If the "E" serial number assumption is correct, it will help me with approximately 6 of the 86 part numbers I would like to order. However, because my engine's serial number is E20830, it is much lower than most of the "A=E/#XXXXX"s provided in the parts list, it brings up the following question,

If the engine serial number is lower than the one provided with the 2-1 part number, do I fall back to the preceding part number- "2 129150-42320 O-RING," for my engine?"

The people at Mastry are very quick to respond, via email, with availability and price of the part numbers I provide. However, they do not advise as to which number is applicable to my engine. Thus far, my inquiries to Yanmar US have yielded not response.

I sincerely appreciate your thoughts/ideas on this matter. If I receive additional information from Mastry or Yanmar I will post my findings.

Thank you for your time.
