Front Wheel Bearing Orientation
#31
You can screw around getting the second bearing depth right by bringing the bearing in close then testing fit but this doubles the time for wheel bearing install and leaves the chance for error. I'm sure most of the tools are screwed up like this as many times the wheel bearings appear tight if checked when changing the tire.
If George want to do it right he need to cut the pressing surface flat then only hog out the clearance between the 2 races. As stated tho, the seal rests below the bearing races. Some might be even but even that won't hurt.

Just a tool observation: George's and maybe some others use a thrust bearing to relieve some of the friction of screwing down on a tight bearing (if its a Harley, it should be tight), but Pit Posse (what I have) and most cheaper ones just have plain flat washers. It really takes a lot of bind out of the tool to grease every surface that rubs, including the screw threads. Also helps to put a film of anti-seize on the outer bearing race, I've seen non Harley cast wheels that really corroded around the bearing. Freezing the bearing just before installing it shrinks it a little, and can make it draw in easier, too.
Nice to have something to hold the wheel, too.

What lubricant is recommended for the outer race of the wheel bearing and the hub area when pressing the bearing in? I've seen both wheel bearing grease and anti-seize mentioned. Do I use the same lubricant in both locations? This is the first time I'm replacing a sealed wheel bearing, hence the question.
TIA

I actually found a few sealed aircraft bearings that had no grease at all in them, but I also looked in thousands of bearings over the years. Still, even a tiny percentage that will definitely fail is alarming in aircraft and motorcycles.

Guys, could use a hand here. I purchased a set of 2011 Road Glide wheels and had them powdercoated. They’re supposed to go on to my 2017 FLHTK.
I bought a Pit Posse bearing removal / install tool set for this project, and encountered absolutely no issues with pulling the bearings prior to sending the rims out for powdercoating. I also picked up a set of All ***** bearings, part number # 25-1691, for bikes with ABS.
After taking note of which side of the wheel had the HD and DOT cast on it (in this case the left or “primary” side) I installed the bearing seat tool from the right side through to the left, put the ABS bearing (with the magnetic sensor green side facing out) on the left side of the wheel, and tightend the nut to draw the ABS bearing in from the left side of the wheel until it fully seated. Next, I installed the spacer in the center of the wheel, reversed the seating tool to pull a non-ABS bearing in from the right side of the wheel, and tightend the tool until I felt the bearing touch the spacer.
However, my right side bearing is sticking WAAAY out:
My left / primary side (with the ABS bearing) has the bearing seated considerably deeper:
Is the ABS bearing supposed to be seated that deep? Did I somehow seat the left side bearing too far? Also, you can see that the spacer isn’t properly aligned with the bearing inside the hub. How are you supposed to keep that alignment when drawing the right side bearing in until it first contacts / kisses the spacer?

FL, you got your "Primary Bearing Side" mixed up and installed that First bearing on the wrong side
Where in your FSM instructions does it say to use the "DOT or "HD" Markings? (they are used in some cases) ... BUT your Original wheels and the 2011 28-Knuckles are marked on opposite sides
The machined groove indicates the Primary Bearing side (the Shallower bore depth side).
And like Max says, you really should clean off the Mounting Surfaces. They should have been Masked before the PC

I guess The Moco should have picked a better word than "Primary" side when referring to wheels. It often leads to confusion. Just to point out for the uniformed...the "Primary" side of a wheel has nothing to do (other than possible coincidence) to the "Primary" chain side of your bike. The MoCo uses the word "Primary" according to it's definition "Main" or "First".
So in the case of your front wheel the "Primary" side of the wheel is placed to the Left (which just happens to also be "Primary" chain side)...What about the rear on your Touring bike? The "Primary" side is placed on the Right-side...what side is the "Primary" chain side on again
The Moco trys to make it easy in their instructions of those Enforcers by stating ...
"The left side of the wheel has DOT markings to identify the primary bearing side."
But there are other designators on those '09-later Touring such as the "Primary" side of the wheel will the more shallow bearing bore and the rotor mounting surface will have a machined groove (won't see it unless the rotors aren't mounted)
