CIH, in all of their lack of infinite wisdom, failed to put any of the W/O/I tractors during the letter-series era into their computerized parts books. I'm pretty sure that the W-400, W-450, W-350, 600, and 650's, and possibly more aren't either.
Probably 1 in 20 CIH dealers have a paper W-6 parts book laying around. Probably 1 in 5 have anyone with any knowledge of a W-6 tractor ever existing.
If I'm reading my W-6 parts book (TC-33B, dated 5/9/49) correctly, there is:
1 bushing in the top of each spindle, 55 236 D (shows up NLA and no sub numbers at Messicks website), no sub number in paper superceded parts book (4-1984)
1 outer race in each spindle (goes toward the top, inserted from the bottom of the spindle in the picture) (for serial numbers 501-2636), 55 414 D (NLA)
1 outer race in each spindle (goes toward the top, inserted from the bottom of the spindle in the picture) (for serial numbers 2637 up), 59 836 D (shows up as $127 at Messicks)
(Book tells you for 55 414 D to order 59 836 D, so the early race subs to the later one anyway.)
20 pivot balls per spindle, D 2615 (book says same as 1110 C) (both show up as NLA at Messicks). Both D 2615 "ball" and 1110 C "ball" sub to 16 012 R1 in my 1984 superceded parts book. 16 012 R1 is listed as a "3/8 inch grade 2 chrome steel ball" (came 50 to a pkg.), (and is also NLA on Messicks site) in IMP-1 parts book dated 12/1968. "Grade 2" was +/- .00005 of any specified diameter. "Grade 1", which was +/- .000025 of any specified diameter doesn't have a 3/8 inch option listed in the IMP-1 book, but in the paper superceded parts book 16 012 R1 "ball" subs to 17 012 R1 "ball" which judging by other numbers in the IMP-1 book, could very well be a "grade 1". 17 012 R1 "ball" subs to 87016924 "ball" at Messicks, and is listed at $2.23. 87016924 replaces a bunch of old numbers, but 16 012 R1, D 2615, and 1110 C aren't on that list at Messick's website.
1 inner race per spindle, (picture shows it at the bottom of the spindle), 55 413 D (shows up as a $73 "flange" at Messicks)
and 1 felt washer per spindle at the very bottom, 55 412 D ($8 at Messicks)
The balls should be available from an industrial or bearing supply house if you have a measurement. You may have to buy 50 or 100 at a time, though.
The "Parts Depot" may have parts available that are NLA from CIH, and may have parts available that may retail cheaper than the bearing race prices from Messick's website above.
Just because a part shows up with a price at Messick's website doesn't guarantee it's current availability in any way, shape, or form.
None of the races, or the balls themselves show up in my bearing parts catalogs (dated 3/1958 and 10/1976). IH could have manucactured these races themselves.
Some people's idea of "inner" and "outer" races may be different than the way IH used them here. They confused me a bit at first, and that's why I tried to explain them the way I did.
