Wheel Bearing Size
 
I'm going replace my wheel bearings, yet another winter project.

The victim: 1991 single axle Mastercraft factory trailer, no brakes.

After researching this, I have not located the bearing kit size. Would like to pre-order the 2 bearing kits online.

Any help here?

TIA!

Not sure if this will help, as my trailer is a '96 single axle Mastercraft but my bearings and seals are as follows:

Spindle size OD= 1 3/8" x 1 1/16"
Inner bearing L68149, inner race L68110 (koyo)
Outer bearing L44649R, outer race L44610 (koyo)
(UFP kit 07007U0)

Seal size is 1.688" x 2.328" x 1/2" wide. Should use a double lip seal, UFP 07027U.

Heres what I used on mine. It's a tandem axle with breaks for an 89 tristar 190 made by sweetwater metal products. Instead of the L68110 I used the L68111 because there was play with the L468110. But that could have been from the bearing explosion From when I talked with Dwayne at SWP they used the same on breaks and no breaks. Actually I have one axle with and one without.

brighac, does your trailer "porpoise" with one axle having brakes? I have same year, guessing same trailer as you - '89 tristar 190 riding on tandem axles.

Nope. Barely notice it back there. Is the boat sitting on the trailer right? I have noticed it seems to be a 2 person job to get the boat on the trailer right. I have found the sweet spot to back it in where the water line is between the two tires on the fender. Even then it's challenging to get it to stay up all the way. Easy way to check is to make sure the bunks are flush at the back of the boat. The trailer has a pivot between the two springs

With the pre greased option, can one just unbolt the old and bolt in the new?

Thanks!

And while you're there, put a set of Bearing Buddy (and bras) on hubs.

A new hub assembly is my preference.

I have BB and BB bras on right now.

Just looking to spend more money on my money pit.
