Stator Part Number issue

PostAuthor: DBK81 » Mon Jun 29, 2020 2:14 pm

I have a 1984 XV750 with a bad stator, the issue I’m running into is when I go to order because this bike wasn’t sold in the USA it doesn’t show up on any parts microfiche, I assumed that the stator was either the same ast a 81-83 XV750 or the same as the 84-86 XV700, so made it easy as both those bike although the stator part numbers are different 42X- & 4X7- both seemed to be interchangeable. So I order an arrowhead AYA4003 which is supposed to be a direct replacement for those numbers, I get the part today and it is narrower and a larger circumference, so it will not slide into the magnetic case, so now I’m at a loss on what part I need, inspected my trashed stator for a part number and there’s nothing. I’ve emailed arrowhead to see if they can provide measurement specs to see if I can narrow it down. Super frustrated, waited 2 weeks for this stator to come in and it’s the wrong part.

1984 was a transition year for the virago --- '83 = Gen-I & '84 = Gen-II

as Yamaha used up as many of its' off-the-shelf parts possible there are sometimes slight diffs in bikes as up-grades were made - fer instance the G-II stator.
had a different 'width' with a collar/spacer up-grade. ('84 - '86) [visible on new replacement in pic]

none >>> https://www.mrcycles.com/oemparts/a/yam ... /generator

vs.

#3 >>> https://www.mrcycles.com/oemparts/a/yam ... /generator

during that time there was also a variation on wires/connectors, too. later, even pick-up coils
sadly, I can't remember which had which right now (senior moment) ...

Mark75, there is a big difference between the ‘84/‘85 700 and the ‘86 700 in your second link. The OP has an ‘84 750.

The one from the ‘86 certainly looks more like the one in my bike. Very interesting. Going to have to try and get someone to measure and send me the specs on the 4PP-81410-00-00 from the ‘86 to see if it matches the measurements for mine. Thank you.

Usually when Yamaha parts interchange, they are noted in the parts fiche. Such as the ‘81 to ‘83 used 4X7-81410-20-00, it would be noted that 42X-81410-20-00 superseded the prior number.

The ‘86 covers are bigger to accommodate the larger stator. More rounded, the ‘85/85 are flat.

The issue is I bought the arrowhead AYA4003 which is stated to be for 81-83 750 and 84-86 700 but it’s approx 1/4” taller than the stator in my bike as well as narrower. I’m at a loss.

I understand what your issue is, I stated what is known to be true.

Perhaps some side by side photos would offer some insight.

yep.
that was my point.
if I read it right; the OP was thinking they are the same
they can be fitted, but are not identical.

Let me try another explanation. If the stator from the ‘84/‘85 XV700 would fit the ‘81 to ‘83 XV750, then Yamaha would add the superseded part number to the ‘81 to ‘83 parts fiche. Since it doesn’t, I don’t know how Arrowhead says it will fit both.

Another scenario is possible, that’s why photos of what you have are important, a previous owner converted the starter to the later model, in which case the engine side cover and stator would be different.

Maybe even an entire engine swap. Do the numbers on the engine match the frame numbers ?
