There's probably a "spec" for that.... and a call to Morrison would answer what you need for clearance. Just to make sure your bearing and race is the right size for the tube.

Mic the housing - and mic the race.... do a little math and find the difference. There will be a + or - number which your number needs to be "within". But they're not "press in".... it should just fit in snuggly.


I'm ASSuming you have TAPERED BEARINGS.... not the sealed BALL bearings.... Ball bearings have a different assembly procedure. I say ASSuming because there's no picture but I can assume you know the difference and have stated "tapered".




The assembly process for a tapered-roller, bigbearing wheel end is similar to that of a ballbearing style, but there are a couple of differences. The tapered-roller, big-bearing style is not sealed but shares the oil with the axle. Do not install a seal in the axle housing or the bearing will be starved of oil. The bearing comes pre-assembled with a pre-lubed bearing and seal as one unit plus the axle-retaining ring. These take the place of a ball bearing. There is still a retention plate and in some cases, a brake specific spacer ring is required on the axle shaft. So when you install these on the axle shaft, they go in the following order: retaining plate, spacer ring, seal/bearing (with seal toward the spacer ring), and retaining ring. The seal outside diameter is a slip-fit in the axle housing end and when you tighten the T-bolts in place, it draws the whole assembly into a preloaded condition. This preload causes the outer diameter of the seal to expand and seal into the housing. This is a very robust wheel end bearing, but it’s tricky to disassemble. You can re-use the seal, but be very careful when getting the already expanded outside diameter in the housing.
