Thanks Owen....... 1798276.....matched to Hyatt barrel roller bearings. To my knowledge, based on the GM manuals at hand, that shallow adapter was CMP use only!!!!!!

Nothing like that on this side of the Pond unfortunately..... However...... I am following up on an external clue.

It seems that the bicycle ball bearings are in most front axle of Civvy trucks and this stayed until at least the early 50s.

The clue to the HD axle and roller bearings is the cover in the center to wheel.... inside the 5 big wheel nuts..... the regualr axle model has a stamped/formed grease cover that is recessed into the hub..... the end of the cap is hex shape like a large nut....... on the HD...... they have a flat or domed sheet metal cover held by 4 or 5 or 6 small 1/4 -20 bolts........ the hub of the C15 has 6 little bolts holding the domed cap.

I am pursuing a Maple Leaf truck circa 41/42 that has a sheet metal cover over the bearing with 4 bolts...... waiting to get it home to take it apart and confirm my assumption that it has roller bearings......

Thanks for all your help Owen.......Alex and others who have replied on other threads.

Here the snow and ice as almost vanished which will let me get my hands on the 1940 1 1/2 ton Civvy Chev from the back field.....just need a wek or so for the ground to dry up or risk sinking to the belly of the tractor.

In the absence of original C15 HUBs I will get adapter plates that will allow me to bolt CMP rims to the adapter plate which in turn will bolt on to the 5 or 10 bolts pattern of the GM civvy Hub.
