Bearing Buddy size

[toolz]

Anybody know what size Bearing Buddy fits on a 1998 single axle M/C trailer with 6 bolt wheels? The boat I hope to buy this weekend is 4 hours away, and I'd like to take a pair along for insurance for the drive home.

I have a 1993 PS 205 with stock trailer/wheels and i just replaced mine with a 1.80

why don't you wait until you buy the boat, then pick up bearing buddies on your way out of town? Or buy two sets, return the one you don't need.

Picking the boat up on Sunday- not sure who is open. The common size I found in the parts places today was 1.980, and will take those with me, but I thought the 6 bolt hubs might not be a common size.

Oh, yeah, I can help you with this question.
If you have the 6-bolt hubs from 1998, you have a UFP 5200 pound axle. The information you're looking for is:

Drum: Unique Functional Products #42 (HD-1750)
Inner Outer
Spindle 1.75" 1.25"
Bearings BR25580 LM67048
Bearing cups BR25520 LM67010
UFP Bearing kit 07009U

Hub Seal OD 3.265" 2.328"
Hub Seal ID 2.125"
Hub Seal Model 326-213-sp2-1 or UFP 07029U
(NOK Equiv AD7131E)
(Transcom equiv 21325TB)

Bearing Buddy Model #2328

OEM Brake Backing Plates: Dico 12"x2", standard.
Brake shoes: FMSI #62

Hope this helps. The Bearing Buddies won't help you at all if the bearings are in need of grease - they barely supply any grease at all to the outer bearings, and none at all to the rear bearings. The grease that you inject with the buddies does three things:
1. It pressurizes the inside of the hub, to give you all the water-rejection features that Bearing Buddies are good for. You could use compressed air for this function.
2. It puts grease between the piston and the bore in the bearing buddy to keep the pressurized air from leaking out.
3. It makes you feel like you're greasing the bearings. You're not.

If the bearings look iffy, pumping up the buddies won't help.

Thanks for taking the time to post all that. I wish all trailer bearings were set up like my newer enclosed trailer- it has the EZ Lube hubs with a zerk on the end of the spindle and injects grease between the bearings. Wish I would have thought of that.

[FrankSchwab]

Yeah, I saw those hubs and thought it was pretty slick...

No problem on the post - I just cut-and-pasted from the info sheet I keep on the computer for the boat. If you're looking at a 200VRS (as the boat listed in your profile), Here's the rest of the info I have. Some of it won't apply to an LT-1, but ya gets what ya pays for.
