Who can press steering stems for me?

[nzspokes]

Im doing the KDX/KX 125 fork swap. Who in Auckland can do the pressing of the stems? Would rather it done right over cheap.

Wouldn't let that coconut do it. He royally fucked up a shock for me and charged a heap for the service.

[Akzle]

cuz just grab yer fuken bottle jack out the back tha ute, get some shit thats the rough enough size, get the fat cuzzies to sit on the bonnet and press that shit against the chassis.


Or just put a box in the boot and cruise through some engineering shops looking for a press. Fuken easy.

Or take them to machinery house and ask for a "demo" on one of theirs!

Practically any motorcycle shop can do that for ya.

[gwynfryn]

I would suggest more engineer/fitter turner/ machine shop over motorbike shop. Must be someone out West who's competent, and let us know how you get on as I want to do the same swap some day.
Have heard it can sometimes take a bit (30 tonne) to push them out and that the kx triple may require knurling for the kdx stem to fit.

[bogan]

Do you mean press the bearing off the stem, or press the stem out of the bottom yoke? If it is the later, it is worth looking onto other solutions first.

Your about 15 years to late to this party. Be going since KDX's and KX's were about.

Yeah Ive been told about 9 tonne is when they let go with a little heat.

That may be, but it helps to provide all the info when asking for advice regardless...

As this is the offroad section and the replys have understood what im doing I reckon the question had all it needed.

Thanks Crasher, ive asked a couple of shops and they dont have a big enough press.

Looks like Tjebbe will get the little job, he cant do it untill mid March but it will take me that long to respoke the front wheel anyway.

[Brian d marge]

Ive done a couple and they aint in there that tight

warm the bottom yoke and make sure it goes in Square to the bearing ( plane) face

Fkin big ammer ( joke !)

Wot he says. That's why I said pretty much any bike shop can sort it. Bit sad if they can't actually.

Then I'd say they simply haven't done one before. Cause as Stephen has said...they ain't in all that tight generally. Certainly no worse than pressing a crank together in my experience anyway.

Ive got a mate with a 9 tonne press so may give it a shot on that. Ta

What could go wrong????

[scott411]

what year KX triple clamps and forks are you using?

I thought you could use the KDX bearings on the KX stem, but it was been a while since i have helped someone do this conversion,

braking the triple clamps

[nzspokes]

2000 KX125 and 06 KDX. Bearings are different.

[nzspokes]

I was more concerned about it slipping and hitting me in the nuts.

You don't want to bend the shaft either.

[scott411]

i know the bearings in different, but are in Inside Diameter different? i thought you could press the KDX bearing onto the KX shaft, but I am not 100% sure,

[nzspokes]

Everything I have read says no. Only fork thats a direct swap is KX500.

[Crisis management]

I know nothing about the swap you are doing but maybe try Pyramid parts for bearings that match the diameters you have. They have a huge range of odd size bearings just for these applications.

[scott411]

Everything I have read says no. Only fork thats a direct swap is KX500.

see if you can get the measurement, I am sure we did it before, it was with earlier forks than the 2000 model, but the KX's ran the same head bearings for a long time, and teh KDX/KLX were always different,

Can get the KX one tonight but the KDX still has its forks in at this stage. thanks for the help. I do know the kx stem is a bit longer.

i have been looking at the all balls fork conversion chart and it says that 91 and early KX125/250 forks will fit, which is what these forks might have been, it was 10/12 years ago we did this, and i have had a lot of good nights out since then,

[pete-blen]

It's a simple job....
I have pushed the stem out untold times
over the years... the only way to change the
bottom bearing...Unless yer want to start heating/hitting/cutting &
all sorts of other back yarder acts..
How do yer think shops change the botton head bearing..?

push it from the top "threaded end" so it comes out though the bottom of the
bottom yoke... theres a step on the bottom of the stem to stop the yoke falling off
if it was to work lose while instaled... the inner bottom bearing race will come off at the same
time don't try and remove it on it own... Just CHECK theres no retaining pins or dowls etc not
common but I have seen it....

I have only just done it a few months ago when I put Honda USD forks in my XT660R..

pitty yer not in CHCH... I would do it for... Only a 15min job...

[nzspokes]

I would have thought using a puller? But then Ive never had to do it.

[nzspokes]

Thinking of this another way, as im not in a hurry I may press the KX 125 one out and get it tuned down to suit the KDX bearings. Reason for that is its alloy over the KDXs steel one. Little weight loss.

You may find the reason the KX has larger bearings is because the alloy stem needs a thicker wall for structural integrity:eek5:

[noobi]

Is there an appreciable weight difference between the two? I bet not.
I dont't think modifying the stem to accept bearings is a particularly good idea, why not just buy some new bearings that will just work?

No such bearing is made is what I believe.

theres no gap between the inner race & the yoke to get a puller in... if yer pull on the bearing cage it will all come to bits
leaveing the inner race still on the stem.. Have to press the stem out...end of story..

Alloy stem.... the CR uses titanium... looks like alloy..


whats the ID & OD of the bearings you require for the conversion ?

[barty5]

Going back a few years but once had a kx250 set modified to fit a tt600 wanted the disc and usd forks on it. Simply had engneering shop trim the over all length as the stem was to long did have the cut more thread tho then a small amount of machining to get the right bearings to fit. Went that way as our 20 ton press wouldn't get the stem out of the yoke.

I had wondered if it could be turned down to suit the bearings with it still on the crown. I would have thought that would be impossible to do.

Cant think of the name of the place but it was in Olive road penrose bout half way down next to firestone western side. Cost stuff all and was the easyest way round the problem.

I have replaced countless steering head bearings.

I've never once had to press the stem out of the triple clamp.

Have to agree with you there even if the cage comes apart all you have to do is the place the clamp around the inner casing and press it off. Heat them right and the new one will faal back into place. Just watch the wifr isnt watchjng you using the oven as a bearing heater and dont over heat.

[bogan]

Use a mill to trim it down, then a live center to steady it while cutting the thread and new bearing fit on the lathe (at fairly low speed).

One I did a while back has those 45deg angular contact ones that come in 3 peices anyway, cold chisel and drift was needed to get enough separation on the bottom casing to even have a hope of getting a puller onto it. It was also a steel yoke with welded stem so pressing it out was a difficult prospect. Fucking kawasakis.

[nzspokes]

Have finally got round to getting this under way in between surgerys etc blah blah.

Even getting the axle modded so I can run the KDX front wheel.

Happy days.

Will give me a little project while I cant ride after my surgery. :niceone:
