Is There Bearing Buddy that is Slightly Smaller that Size for 1.98 inch Hub Bore

Question

Question:

I own a Mastercraft 1998 SportStar. The trailer is a 1998 SS-19 single axle equiped with brakes and the Bearing Buddy Axle. VIN is 19MC31S18W2000374. Trailer rating is 3740 lbs. One of the Bearing Buddies recently fell off while trailering. Can you tell me what size Bearing Buddy fits this trailer? I tried an after-market 1.98 and it was slightly too big. Thanks.

Hey David, so the next smallest sized Bearing Buddy is the part # BB1968 and then # BB1938. That's just a little smaller than the 1.98 size you tried so that is PROBABLY what you need but it would be best to measure first to be sure.

I don't think that's correct. Per the Bearing Buddy website, there is also a 1.968 and a 1.938.

@David You're right! We have them with part # BB1938 and # BB1968. When I looked at our list of Bearing Buddies for some reason that size wasn't being shown yet we definitely do carry them so my apologies. I would use a caliper like # PTW80157 to get an exact diameter of your hub bore to be sure.

Answer 1

Believe it or not, the outside diameter of the Bearing Buddy is designed to be a bit larger than the inside diameter of the hub bore. Typically, a Bearing Buddy sized to fit a 1.98 hub bore will actually be about 1.986 in diameter, which means yours…

Answer 4

If there is any corrosion built up on the hub, it could be built up corrosion built up on the hub bore making the hole read smaller. Grease caps do not have to be very deep. They only have to go in far enough to fit snug and tight inside the hub…

EZ Lube Dust Caps, like #DC200L-DCRP, have a rubber plug that can be removed to access the zerk fitting. The rubber plug can be removed by gently prying it up with a flathead screwdriver. If your dust cap is in good condition and you want to avoid…

Both the 4.80/4.00-8 and 5.70-8 tires sizes will fit the same wheel size, 8 x 3-3/4 inch. The 5.70 is taller by 2 inches and wider by 1.2 inches. If you have more than 1 inch of space between the tire and a fender and more than 1.2 inches between the…

Answer 7

We may have a grease seal that will work in your application however, my research had conflicting measurements for the Hadco 3122 that you referenced. I contacted my technical contact at Redline to verify that the Redline Grease Seal #1105-100-031…

Answer 8

It sounds like the Grease Seal #1105-100-031 that you referenced would be the correct seal for you. This seal has the same inner and outer dimensions your seal has. This seal has a inner dimension of 1.750 and an outer dimension of 2.35.

It sounds like you currently have #L44649 bearings with an inner diameter of 1.063" and a grease seal like the #34823 with an inner diameter of 1.249". For a hub that matches these, along with the 4 on 4 bolt pattern, we have the CE Smith…

Answer 11

The closest grease cap we offer to what you would need is the part #F001524 that is designed to fit hubs that are 1.943 inches. 1-15/16 inches in decimal form is 1.9375 inches.

Answer 12

While the #L68149 most likely corresponds to the inner bearing number of your hubs. If this is the case, you have either a 3.5k or a 4.4k axle. In order to know absolutely sure, you need to know the corresponding outer bearing number or the inner and…
