One "other thought".
Did you rummage through the metric or SAE collection of retaining rings when you were at the hardware store ?
I am thinking that it is "POSSIBLE" that there is a SNAFU somewhere between the manufacturer, the parts counter suppliers and wherever else.
Without knowing whether specs (if any) are listed in metric or SAE and who complies with what wherever the groove is cut, where the retaining rings are bought in from, etc.
It could be a mess.
Probably metric in the country of manufacture, but who knows how torqued up things might get when spares are spec'd for the US market.
Maybe this isn't a_NOTHER thought, since your post had a mixed inch/metric reference in it ?
(-:
"the closest size, 1.5", which is about .6 mm smaller than the metric size.
That is WAY smaller than 40mm
Ummm,, 38.1 ?
I would guess that MIGHT be for a groove in a 40mm SHAFT ?
I would also guess that a 40mm ring would fall right off a 40mm shaft, but you seem to already know that (-:
