How to disassemble seal head on KYB's?

Recommended Posts

A friends KX125 93's shock is over and I want to give it a complete rebuild.

Everything went good so far but how to remove the oil seal in the seal head? There is a lip on top, bent inside so the inner metal plate cannot come out.

1. What to do to unpeen it?

2. What to do to peen it again?

i cannot replace them for cheap as i am in a country where this kind of parts are not available. i have to order from outside, this takes long time and costs...

therefore i need to open it.

Time = money...how much is your time worth? Whole seal head is around $35.00 US.

is it easier to get the oil seal instead of the complete seal head? :bonk:

@KTM-Lew

this one unfortunately is more expensive. it sells at 45 Euro (khan is from Turkey) which is +50US

I have rebuit these a few times, I just get out my Fordem porting tools or Dremel and remove just enough metal to get the bushing/seal out. Reinstall the new stuff, then peen with a punch atleast every 1/4 inch all the way around the where the old "lip" was. Never had a problem.

Worked for me but of course ,it might be safer to by the whole seal pack:ride:

i managed it!

just used a round iron which is quite big round and fits inside the seal head peened edge.

then hammered the round iron that it gives the edge a hit to bent out. done this all around the peened edge and that's it!

now I got all parts from it out, changed the bushing and will try to find a new oil seal.

thanks guys!

Good idea, I have a small lathe now, so next time I may take your approach of no metal removel. I can just machine up some kind of big punch.

Mx-tech.com has seals.

I use a small screwdriver to first pry the rubber out. Then I use a small set of "ignition" plyers and just grab the lip and peel it back. Go all around it with the plyers about a 1/4" at a time. Takes me maybe 3 to 5 minutes to rebuild a seal head including the bushing. 👍
