Case 1570 pto gears identify??

Have a puzzler here. I took a set of PTO idler gears out of an early 1570. Part numbers should be A138184 & A138185.
They should have one snap ring between the bearings. These gears have 2 snap rings. The bearing hole is 2-7/8" dia. These gears should be used in early 1570, middle ser# 1370 & late 1270 but all those parts books only show one snap ring. Does anybody know what I have here? I'm just trying to get them cataloged with the right part numbers. Thanks for any help!!

I am not positive but I think those gears do have 2 snap rings even though the book might show only one. Could be a mistake in the picture. I will check the books tomorrow. Rod.
 
No I had another set and they only had 1 snap ring. Then the bearing races are flush with side of gear. On these with 2 snap rings the bearing races stick out wider than the gear and wouldn't fit in the housing. I dont have the housing that these gears were originally in so I can't compare that.
