Rookie Ktm maintenance ?'s

[fremontguy]

Trying to get the wheel spacer,seal out of rear wheel. Pry and pound with screwdriver? Bolt rod inside swingarm to bell linkage stuck. Again, do I pound out with socket extension? Does anyone know the torques to the 17mm, 19mm nuts on linkage, use locktite? No wonder I put off these jobs, thanks in advance.

KTM maintenance

Plenty of WD-40, brass drift, and a hammer. Have fun

When you put your bike back together apply anti sieze to the swing arm shft.
This should be done on axle shafts also. This will end the tight shaft syndrone.
It is not a good idea to drive in the new wheel bearings on the KTM hubs.
Better to use a threaded rod. Run it all the way through placing a large washer and nut on one end and using a socket as a press head on the side you are putting the bearing in. Better to make up this press because I have seen the hubs form hair line fractures from pounding in wheel bearings.
These fractures end up getting worse and eventually the hub breaks.
Same type of press works good on the heim joint for the shock.

Good stuff so far, I'll get a brass drift. No Heim joint here, full on linkage:ugg:
Found a thread on wheel bearings here: http://www.dirtrider.net/forums3/showthread.php?s=&threadid=5497&highlight=wheel+spacer

Confused as Usual

I'm lost as to what is stuck?? " Bolt rod inside swingarm to bell linkage stuck Again." Does this mean he can't slide his axle out to get the rear wheel off? I need to know so I can go take mine apart and lube it properly.... I just got a 2001 300 EXC and any initial things I should do would be helpful. Any history as to these bikes needing the steering head bearings lubed from the get go??

Thanks, R.R.:cool:

Clarifying, 2 different stuck items: wheel spacers on wheel(axle comes out fine), and bolt inside swingarm closest rear wheel. Newer pumpkins don't have this linkage. Haven't attempted main swingarm bolt yet, assuming more fun there. The steering head was a piece of cake to lube, and looked great.

for the guy with the new 1: put anti-seize paste on the chain adjuster bolts & fork pinch bolts. put loc-tite on the shock bolts & sprocket bolts. check the sprocket bolts frequently, esp. at 1st. enjoy!

So back to the swingarm and Linkage. I removed swingarm and L shaped link from swingarm, internal tubes seem to be frozen or stuck in place. Is there a easy layman way to remove these bearings? I take it needle bearings also need to be replaced?

I noted in the thread you found some were debating the packing the bearing full thing. I can tell you that you should never fill a bearing housing of any kind more than 60-70% full of grease in any situation, high rpm's or not.

Ok, part of the mystery is solved. I was able to knock out the endcaps, bearing sleeves on parts. Now it's just a matter of cleaning the bearings and re-greasing inside linkage. It sucks doing things the first time.
