I used Phil Woods Waterproof Bearing Grease.  A leftover I had from my time served as a bicycle repairer.

Lots of people use automotive wheel bearing grease.

Important part is to clean the bearing races and inspect them thoroughly.  Needs to be a smooth and consistent surface.


Will do

I use Belray waterproof grease and that is the correct amount.  Congrats on not losing any

Alright I am diving into this.  My AllBalls tapered bearings came today. 



Anyone have any advice on getting this bottom race off the steering stem?  No one covered it in any videos.  It's. Its not coming off and I don't want to damage it.

cut it off w/ a dremel.  you wont need it.

Freeze your stem before seating the bearings onto it.
Freeze the bearing races you install into the neck.
Makes it go together that much smoother.

The stem is frozen, but my dremel is many miles away.  But I am starting to think this thing isn't coming off without it.

You can use (carefully) a cold chisel and separate the race and get it to slip off after a bit of time in the freezer.

I might try putting a dremel wheel on this drill

Does it matter which bearing pack goes in the top and bottom?

I think the grease is fine. IIRC yes, it matters which is top and bottom - refer to the packing list and part numbers.

When you're putting the lower on you really only get one chance - so read, read, read and make sure you put the correct spacer underneath.

Others may disagree on the grease, or even methodology.  I just went through all this not too long ago.

I have never had to freeze anything.  You will need some well aimed whacks with a chisel and a punch.

I gave the shop tech $5 to press the lower bearing onto the fjr.

They look at you funny when you bring a "complex critical service" part to them without the rest of the bike.

I pressed it together with a threaded bar, some washers and the old lower race, ala someone else's video.  Worked like a charm.  I have it back together, now I just need to learn myself how to bleed the breaks properly.

Well, if anyone does see this looking for help, I think it was a success.  I still might take it down to have someone give it their professional blessing since I did disconnect the brake line to the front and the tachometer cable. 



I just propped it up on the center stand and put some books and wood to support the front for taking the front fork off.  I took off the front wheel by unbolting the front fork axle holders (retorque 13.1-16.7 ft lbs).  I slid out the forks by undoing both the upper and lower triple tree bolts holding them (also 13.1-16.7 to retorque).  I unscrewed the tachometer cable at the gauge and the break line at the caliper to fully remove the front fork. 

I took off the steering stem nut from the top, large nut in the top center by the handle bars.  It was 30mm so I had to go get socket.    Then I could pull off the handle bars.  I brought over the lawn mower and tied the handle bars to the mower handle so it wouldn't be hanging by the wires.

Next there is a spanner nut holding in the stem and bearings.  I got it off with some channel locks, I couldn't even find the right tool at the store.  Be ready to catch the stem and bearings when you take this off. 

I used a small crowbar wrapped with electrical tape and a small sledge to pound out the races left inside the frame.  I broke the old race pressed onto the stem loose with a small sledge and three chisels very carefully.




I got the All Balls tapered bearing kit 22-1011.  Inside the box the 99-3512 goes in the bottom and 99-3511 is the top bearing. 



It comes with two washers of different thicknesses.  Take the old lower race, upper race with a few bearings and some grease and measure them.  Do the same with your new lower bearing pack with the dust guard and choose the right washer to get the measurement the same within 1 mm.  My old bearing pack was 19 mm and the new one was 20 mm with the thinner washer provided. 





I put the steering stem and the new bearing packs in the freezer to get them to contract a little.  I took out the stem, height adjustment washer and dust seal and pushed the two down on the stem.  Then I took the lower bearing pack and carefully pushed it down on with a chisel and hammer, making sure I only touched the inner ring of the bearing pack. 

The new upper race went in very easily, I basically just placed it in and it tightened in there once the metal warmed up.



The lower race needs to be a little further up in there than I could bang it with a hammer, so I rigged up this gadget to press it in with the help of the old race.





Now you are basically done.  Grease up the bearings, put it all back together, retorque and bleed the brakes. 

Went for a test ride this morning and my wobbles were gone, so I think it was a success.  Then I found a snapping turtle and helped it cross the road.



I am no expert, so please only use this as one reference and watch some videos etc.

Yea I didn't touch it.  Just stood in the road and nudged it to the other side.  I've been seeing a bunch lately.  This one wasn't even half the size of one I saw the other day, I doubt I would have even gone near that one.  I really wanted a pic, but I was on the way to a job interview that day.

There was wood in there too.  Really bad idea?  It never felt like it was going to fall.

I have stopped to rescue a turtle before, don't think we have snapper turtles here, but I really regretted helping this one off the road cause it bloody pissed on me and it took days to get rid of the stinky smell on my hands!

I once successfully used my helmet to prop up the front of my bike while I took the wheel in for a new front tyre...
