Front fork oil seal change...

I have a '02. Do I need Kawi's specialty tools to disassemble my front fork and change the seals? I have the manual(which is not very helpful), and it claims I need 3-4 tools. Help!!

I have never done forks so please forgive my ignorance. :P

I bought the ninjette three weeks ago(already leaking freely out the top of the dust seal) and I have put 400 miles on it. Stunningly, the front suspension doesn't feel right. Please advise! I would appreciate any tips or tricks from those who have done forks before.

Thanks--Brad

I highly recommend getting the Motion Pro Seal Driver. They have a really cool on that splits in half.

I also recommend getting the Motion Pro Fork Oil syringe so you can properly set the air gap

The Damper Rod holding tool you can get from Amazon for like $20. The brand is Pit Posse

You can get copper crush washers anywhere. I actually bought a box from Harbor Freight for like $2. I do a lot of fork oil changes for multiple bikes so this was a no-brainer. It comes with a lot of various size copper washers, so I use them for for crush washers for oil changes as well as brake lines. Plus, at $2, its cheaper than buying 2 washers from the dealership.

Fork seals I bought from Racetech. It may be a good idea to get the inner and outer bushings just in case they are worn out. They take a while to wear out, but if they are they need to be replaced. Otherwise you will get vertical burn/scorch marks on your fork tubes. If your dust seals/wipers look like crap, change those out too.

I highly recommend using an impact driver to get the damper rod holding bolt at the bottom off.

Does this look right for the damper holder?

Yep, that's it. You will need a long socket extension or bunch up your extensions. I actually bought really long extensions from Harbor Freight specifically for this job. The damper rod holding tool needed to be hammered into the socket extension. I didn't worry about needing to remove it since I bought the extensions specifically for this use.

I bought OEM seals two weeks ago.

I found a Motion Pro 36mm seal driver for $39 on ebay.

There's a how to already posted on here with good pics. It's pretty thorough...however I have no objections adding to the DIY knowledge pool.

I guess it's up to Alex...aka "god"

The current DIY for fork oil and seals is done with a newgen(at least the one I saw). I will take pics as I go and will post anything useful I learn.

The internals are identical afaik. The only difference is the size of the forks and the oil level/spring rate/etc.

That was great.

I am wondering, though, did I miss it or did he not use any specialty tools? Does the PVC replace the seal driver? And is the front fork holder replaced by the bench vise?

Yes, the PVC replaces the driver. Go for PVC if you don't plan on working on forks too much.

The the damper rod is the purple thing in the picture. The rod can spin when you are taking on/off the bolt at the bottom. To stop the damper rod from spinning, you can insert a holder from the top to stop the spinning.



Its not always necessary to use the holder, sometimes the springs under preload exert enough friction on the rod to stop it from spinning.

Thanks for the clarification. I did already buy the tools. :-/ But you can never have too many tools.
