G'day all.
Does / has anyone got the numbers for the headstock bearings? Replaced rear set last week as they collapsed (6304 and 6305). Headstock has play, greased em 2 yrs ago ( roughly) and as its my daily ride for work don't have time to pull it down get numbers rebuild it ride into town and pull it down and rebuild it again.
If I can get numbers I can get them from bearing shop. Help is greatfully appreciated.
Will post pic of failed wheel bearing as in no pic didn't happen thing .
Cheers
Neil
Here us the RPM steering head bearing kit that includes the lower bearing seal.

This was for a 1990 FJ.
For reference the upper steering head bearing is a KOYO......32005JR........Timkin 32005X
The lower steering head bearing is a KOYO ........................32006 JR with a bottom seal.
If the post isn't to steep RPM also has them.
Neil, the lower race is a bugger to get out. There are different ways to get it out. I used a dremel with about a dozen small cut off wheels and sectioned it out... Some have carefully welded a blob on to provide a shoulder for a punch. The top is easy to get out with a punch or drift.
Just a heads up on the bottom. Don't be in a hurry.....

If you got access to a welder for the bottom race, its a 5 minute job. Weld around the race in the middle, then wait for it to cool and shrink and pry it out or weld a drift to it then tap it out.

G'day
Thanks for the numbers and information, randy if it wasn't an emergency you'd have my order but I need them as in tommorrow . The pic above is my rear from a week ago, was coming home, 100 k zone so kookaloo cruising, comes to an 80, blip the throttle down a gear and roll to 80. 3 k later a 60, same again throttle and down a gear roll to 60. A bit up the road needed to stop at IGA, pulled brakes on and the bike went graunch and pulled to the right and felt like I copped flat rear tyre. Pulled up, looked, looked ok went IGA to get smokes, rode home a k an a bit, did it again at turn to my house, got home put on centre stand, rocked rear wheel and almost fainted. Lucky I didn't touch the brakes from 100 ish to 80. I put those bearings in so at a minimum I got 90 thousand k's out of them.

Uh!, excelent price!
No problem, I see George has posted the numbers of the individual parts. Fortunately, the steering head bearings are not ball bearings, but caged tapered roller bearings, so you should not see failure like you did with the ball bearings used in the wheels.
I just posted up the kit as an option for you.

Great read! I too learned the hard way last fall (seems like the only way I learn anything) that it's much easier to break the bead BEFORE cutting the tire.
Just waiting for the snow to melt...

G'day again
All good as you can see, bearings buggered, brinelling and scoring. I like the way the PO ground 2 grooves.....
Used a stick welder on lower race, general purpose rod, ran a weld round race, talked bullshit to my dad for 5 mins, tap tap tap clunk. Race out. You were all right though, be a bugger to do any other way..!
Cheers again for the numbers,all good even bought skf feeler gauges lol !
Did fork oil change, bled brakes and clutch, fixed leaking rh cover, ( ask about that later I will ) and a general clean. Attack plastics with bog tommorrow to fix broken panels from my inertia stopping bitumen moments.
Cheers again

Look's like you got it done Neil ! I dislike overhead welding... Not my favorite way to weld.
George
Its the little tricks you learn along the way that make life a hell of a lot easier! I got taught this way of removing bearings and the like when i was 15 and have never forgotten it. Great stuff.

I just did some overhead welding this past week for the first time. Wow...did that take a lot of practice! By the fifth piece, the welds were looking respectable, but not fun at all like a fillet weld on the bench. Very narrow margin of error on the stick out, distance, wire speed, voltage, angle, pattern and the weld speed. Get them all right and you're good. Get one or two wrong and you have welds that look like bubble-gum. :shok:

You could just about fill a book with tips and techniques but "heat and hammers" will get anything (automotive) apart and makes most special tools designed to do so redundant, and in many cases, less efficient.
