Hi

Got a slack in both my forks.
Any tips on replacing the guiders.
BTW: will replace the sealings too, even if they are not leaking after 35kmls with rubber booths from R75/7.

Reason for slack in the fork, we do have a lot of cracks and holes in our tarmac due to frost damages in the spring and
from time to time I use to travel on gravel roads.
That's how it is in notherst sweden, kind off alaska climate here.

It's radial slack that you sence at the sealings AND while riding.
Front wheel are takiing it's own path, kind of, it's so bad but at more agile riding it gives a fleeing of unsecureness.

Sounds like a steering head bearing problem to me.

If there is play in both the forks, seems like you'd want to replace the bushings - part 31422310347

Hi

Will make a wrencing party and replace the Bush'es ( as I refere to as guiders kind of swedis-english .. sorry ).
Nope I have not replaced them yet.
Diagnose took two persons one rocking the front wheel and the other placing the finger tips on the streering head respective the sealing on the fork.
No slack noticed at the sterring head but at the seelinig.
The other person assisting when detecting the slack are earning his $$ as a gov. car and bike and truck-inspector.
Will take some pictures replacing the guiders and probably in the end also forced to renovate the steeringhead Smile

Hi

Meet that BITCH before and will take it relaxing, some bottle of beer, nice fellow wrenchers and a big piece of paper under the front of the bike.

Hi
Renovated the fors today. 1 bushin absent the rest 3 well used.
Pls. don't ask where the missing where, can be a mistake from my side, or any previous mistake. Anyhow it's more stabel now, anmd noticed that the steeringhead needs a renovation too, not critical but noticabel when turning the forks w/o frontwheel and breaks installed. No slack but a change of resistance by turning at the centre position.

Replacing the bushins are basically the same as replacing the forkseeling, only adding the replacement of bushin and giude bushin.
A note do not mount the upper sealing on the fork slider instead slip it on to the fork leg and while pressing the bushin togeter slide the the fork slider upp on the leg.
Secondly grind of the upper sharp edge of the fork leg bush first and then compress the bush by decrease the diameter with one edge of the bush over the other before mounting on the fork leg.

On getting out those .."bitch".. snap rings, use a highrew grinder and grind a out a bit of the forkslider above the snap ring se: http://wbsp.arb.ltu.se:8020/Private/k11-tech-pictures, then tap a small screwdriver behind the snap ring and take it out. Makes life a bit easier.

Filled the forks with 7.5 weight fork oil, mixed 50% 5 and 50% 10 fork oil.
Used hydraulic oil from Citroen before nad decided to use fork oil this time.

PS. installed rubber boots from -76 R100 to protect the fork legs from dust+small stones+ mosqitos. Seems to work well but gives a funny sound at forkcompression. Opend up a small hole it the rubber boots to not have them blowed up at compression.

Total workingtime appr. 2 hours. Mostly with tools from the tool kit. exept for a hammer Smile

and a allen-key alike tool to dismount the ABS-pickup.
And a beer Very Happy

Any plans you both will be on a small tour next time I need to fix my forks?
It's only a litle detour from central europe, a bit east of FL.
On the way to nordkap, does it sound tempting for a holliday. Wink

Yes I know there are people with magic touch in their fingers and a lot of patient, as for us other this could be a tips.

Made a 300km test ride today.
A significant more stable chassi at more agreesive ride, think I will stick to it at least this summer.
Was in the mode to swap it for a -06 and on 156HP GT.
