Ok, I guess this is a bit of a continuation of my earlier post regarding the front wheel bearings of a 54 9430. I found the B45 bearings new, and a set of NOS B46 bearings, but to my suprise when I recieved them they had the same wear groove on them as the ones I am replacing. Initially I thought that the wear groove was bad as only one of my bearing races had it and the other one did not. Now when I cleaned up the cosmoline on the NOS bearing races they have the same groove. I am now wondering if I bought these bearings for no reason if the groove on the race is "normal". Looking for some help on this one please. Is that little grove on the inner race normal on new bearing sets? The original bearings are the New Departure and these look like a 909046 from Sweden (pre SKF) I am thinking. First Picture is original ND front left, second picture is original ND front right and the third picture is the NOS part.[img]https://www.stovebolt.com/ubbthread...822/filename/20210120_205842_resized.jpg[/img]
I wouldn’t be hesitant to put any of those bearings back into the truck The bearings is low speed and well sized for its load. And Even if or when they fail it’s not catastrophic, you’ll hear it screaming for a month and the vehicle will still be drivable.
May as well use the better one now that it’s apart
Just follow the service instructions to properly preload the bearings when installing it Use good grease, not the cheap stuff for the joints on the cultivator.
And make sure to hang the old bearing on the shop wall as a warning to the other bearings in the truck -s
Hi TrevorC, this is what my set looks like and it is going back in soon. After degreasing, I was amazed to see this after 69 years. Best of luck on your reassembly Ricster
I will relate my experience with a failed front wheel bearing on my 1951 1 Ton. I was coming back from a summer show and as I slowed down in a nearby town I could feel that something was wrong with the passenger's side. As I applied the brakes to pull over to the side I heard some strange noises. I got out and noticed the bearing was smoking. After a ride home on a flatbed I discovered that the bearing had failed, partially melted and was welded to the spindle. It took me almost a whole day carefully grinding and filing to get the assembly apart. Luckily I was able to save the spindle but it was a close one.
Thanks for the pics Ricster. I am just baffled by the little ring mark that is no doubt a tooling mark. But why are they there on some races but not others? I have no doubt they will be fine I just dont like surprises.
Any wheel bearing grease that has a "DB" rating is far superior to the original grease that was specified for stovebolt trucks, both in load carrying capacity and temperature tolerance. "DB" stands for Disc Brake, and discs and the bearings associated with their hubs operate at extreme temperatures and loads that drum brakes never approach, even under max load weights and hard braking.
