Can someone ID this?

[Kiwirider]

Howdy all.
Since riding weather is few and far between now days. Ive decided to do a little servicing. Ive pulled the clutch pack, cleaned and checked tolerances, cleaned out the primary.
Now what Ive noticed, is on the main shaft behind the clutch pack there was what appeared to be an old O ring. Now is this an O ring, or the remanence of RTV or some part of a warn seal. There are no leaks or any play in the main bearing area.
Its the orange looking ring. I've pulled it off and its fairly ragged. Ive also tried to match it up to anything in the Manual, but cant really pick it.
Any ideas?


Also on a side note. Im draining the Trans and have heard about people using Diesel to flush it out, then another flush with oil, then filling with the good stuff (enter favorite flavor oil here). Anyone have any views/thoughts on this?

Cheers all!!

That O ring seals against the inside edge of the flanged hub to prevent oil cross contamination.
Not to sure about flushing with diesel. I would just drain the fluid and fill it up again.

Thanks Kapt. I noticed on the inside of the clutch hub that it was bevelled, so I was leaning toward it being an O ring. Ill find a replacement at work and hopefully get it all back together this week (knock wood). I also have the swing arm off to replace the bearings (on order) as they are the last ones I know of that I havent changed since I got her. Have tried to service everything myself and have everything off except the Eng and Trans. Definitly a labour of luv lol.
Cheers Kapt!!

Don't forget to grease the clutch push before putting everything back together:up: I'm still learning

That O-ring you do not need and do not want to put back in!! It was actually a service bulletin to remove it if the primary was apart. It was shown to give false torque on the hub nut. You think it's torqued down to spec, but it's actually pushing against that O-ring (that's why it's all cut up) and after time, the nut will loosen up. You don't need it, it will not leak not having it, so leave it out.
As far as flushing the fluid, the time I have heard of this is either from having the bike go under water, or if someone was using Red line fluid in transmission. What are you running now? I would just let it drain overnight if the fluid is cold, then fill with Spectro 6 speed full synthetic 75-140 fluid.

Thanks for the heads up Tech. I can see how it would go that. It would compress under torque, then deteriorate and reduce the torque possibly loosening/or aiding the clutch nut to come loose. One less thing to worry about then lol.
As for the trans, last fill was HD semi synthetic. I've been looking for Spectro oils, but no one has it locally and to buy online I've found shipping needs a kidney and my left nut to get it to me. The reason I asked about flushing was when I drained and pulled the primary off, I was surprised to how much crap would have been left in to contaminate the new oil. As I also have the oil tank off, I drained that as well (squirted in a little brake cleaner) and a shit ton of sediment came out of that. Just thought the tranny might need the same treatment.

While i was dealing with my clutch issues i did pull everything out of my Primary side, and because it was coated in crud i elected to clean it with diesel because it would not dry out, maintain a barrier from corrosion while apart and would not adversly affect any oil that you are going to put into the system.
De-greaser requires water to finalise the cleaning process, who want to put water in their primary?
Petrol drys everything out and can cause rust areas, so once cleaned you have to coat it in some sort of inhibiter.
Basicly if Andrew say to do it like this or that, he is correct. The man knows his Dog's.

 

[Kiwirider]

Yup. Thats exactly why Im on this forum. Guys like Andrew and yourselves who know the tricks and traps of these beasties. Im lucky in that I can take parts to work and clean them in a parts cleaner bath or brake cleaner them shiny. Im a clean freak when it comes to maintenance and servicing. I like to remove ALL foreign material before I put them back together (time permitting). That way I can pick up any damage or wear that might otherwise be missed.

Thanks for your input gents. Ill do a write up once I get everything back together and running (knock wood).

What year did Baker stop using that 'O" ring?
I have a 07 K9 and wondering if I need to add this to my worries about my currently perfect running bike!

Let me put it this way! I have a 2008 and had it there when I took my transmission off. Mine is now gone...

Yours might still have it unless you can verify the SB was accomplished on your scoot...
