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
2 129150-42320 O-RING
2-1 129054-42320 O-RING
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.
