hi all,
i'm still reconditioning my m47. i pulled the old m47 front countershaft bearing out (p/n 1209392) without pulling the shaft out, which was easy without a puller. After that, i was ready for a machine shop to cut a groove in my new bearing for the clip the old bearing has. the new bearing, nu304 ecp, is the same in all respects as the original, nla bearing but without the groove for a clip.

i contacted 3-4 machine shops asking if they can cut a groove into my 2 new bearings (one as a spare) which they can use the old bearing as a template.

i didn't receive a reply from any of them. so, i decided to use my old, still-good condition, original bearing but with the new bearings and cage. i did check on the inside of the old bearing and it's in fine condition, reusable.

i would prefer to use the new bearing, but i can use this "rebuilt" bearing for now and maybe cut the other new one, later.

the bearings are easy to remove from their polyamide, pliable cage. the cage is a smaller diameter than the bearing, so it can be easily removed and dropped in.

i took some photos to show that something can be done about nla bearings with a polyamide cage.

here, i'm removing, pushing out each bearing carefully using a small flathead screwdriver. i don't want to scratch or mar any of the new bearings.


next photo shows all the bearings and the cage out of the new bearing.


final check of the old bearing, front back and the inside and dropping in the new cage in it after the check.




here, popping in the new bearings, easy because the cage is not brittle.


my "new," now available, volvo in-stock, "skf" bearing. finished with the new skf bearings and cage in the old outer bearing with the clip already in place. i couldn't find any bearing name on this old bearing, front or back, strange. i'll use the money i saved to buy a case of good cold beer for this texas heat.


regards,
