Maybe. The internal parts might be different (remembering as best I can) The larger one is a spline about 1941 and later or dog style if early 41 or earlier. An adapter to the larger sixe is easiest.
If one is jumping out, Pull it out and you will see if it is dog driven or spline. Tranny countershafts must be changed to match the PTO drive style. Jim

You may be able to get a pto adapter that will lock on the smaller one to make it the same size of the larger on.

There are 3 different PTOs in H the breaks are serial number 501-45613, 45614-117999 and 118000 and later, the latter 2 will interchange, the latter 2 will not fit early tractor unless you change transmission countershaft.

The easiest way is get the spacer that goes on the small one making the standard 1 3/8. I have one if you want it.
