Mk 2 Steering head bearings - tech details

[fallenmikethebike]

Oi ' FFS their only little dainty size 8 's , just for that I'm going to include my Y- fronts into the deal , now there's real penance , as my ever and , long suffering trouble and strife would confirm
And i want proper Dubin ,non of your cherry blossom nonsense .

Let's hope KK has done a sterling job on FMTB's under-crackers....................

Now then, steering head bearings.........

Anybody got any bright ideas on how to get the bottom inner race off the steering stem? The bugger is stuck fast and all I've managed to do so far is bend the bottom seal beyond all recognition.

I gave it a liberal dose of penetrating oil but it's still stuck. Thought about taking the stem off the bottom yoke and trying to drift the race downwards...........assuming the stem isn't stuck fast to the yoke (lots of pen oil applied).

What do you reckon?

Oh, yeah - presumable Mk2/3/AR stem, bearings, and races are all the same size????

Havn't we been here before ? ,i think the best advice was a dremel or some such mini cutter wheel and slice the beggar enough to weaken it , then set to it with a twatting mer

Yep, we have Mike..
Id quite highly recommend NOT pressing the stem out! With the right size drift and some accurate class 1 tw*tting, in a circle pattern, mine came up and off. Fraid you are bound to knacker the seal, but you get one in the All Balls kit...
The Dremel way works too..if youve got one...

Blunt cold chisel between the seal and the bottom yoke, beating the fek out of it with a hammer, and as KK say's, work around the stem in a circular motion. If that fails, cut the bottom race off with a dremel, or disc cutter, CAREFULLY.

For this I use a disc grinder
Not as bad as it sounds. Grind a flat on the race and just before you grind through it discolours. At this point stop and give the race a tap it will usually pull straight off. Obviously you need to take it easy and avoid touching the stem.

There you go RD,

You'd trust your missus with a grinder near your stem What if she had the bit between her teeth

Thus spoke the voice of bitter experience

I guess that so far I've only tried Class 2 tw*tting with the wrong sized drift............

I was a bit concerned about damaging the yoke where the stem fits in - after all you wouldn't want your stem to be a sloppy, loose fit, would you?

Unfortunately if your stem has been in and out a few time it may well be a bit sloppy by know however help is at hand , as there is a procedure available now that returns it to that good as new condition:lol: .

Pleased to report that a spot of class 1 tw*tting last night did the job and my stem didn't become loose either

I think what you are talking about Mike is that blue stuff that Loctite offer..its called 'Bye-aggro'...its chemical name is 'Mystemsafloppin'. Its quite expensive from specialist retailers, but apparently, so Ive been told, you can get it cheap on the internet.
Sounds like Mike knows all about it....

But dont get mixed up with a similar product called "cokloc", otherwise you will not be able to remove your nuts from the tip of your stem. Instead, try a spot of "scrote-slip", made by ass-troll. Excellent for the quick removal of your stem in tight situations.

Hope this helps
