Easily replace motorcycle fork seal quickly without taking forks completely apart

When changing a leaky fork seal, most videos show the entire fork being dismantled . They take out the lower hex screw and use the stanchion to hammer the seal out.
The lower hex screw is very difficult to remove and there is then an increased chance of fork oil leakage at this point.
This video shows removal of the fork seal and replacement using the old fork seal as a driver.

it's easier to remove the bottom bolt. better safe than sorry. one scratch on that shaft and you'r leaking for life

Thanks for the comment .
I had a look at the bottom bolt and my Allen key wouldn’t budge it . I know an impact gun on a suitable hex adapter would have done it but that requires more tools to buy or borrow.

yes if you dont understand how it works but still wont to work on it wy not just take the fork apart its not hard to do

[@Dentinvent]

I watched the correct videos in fork disassembly and understand it all .

I think I had massive patience. I had fun and at least my fork doesn’t leak . That was the aim.

7:29 ... yes it does have that spring, but you can't see it on this type of seal, as it is 'build in' behind the rubber lip

Thanks for letting me know . Maybe mine now has two springs ?

That’s so much more work than removing the bottom damper cartridge bolt and separating the stanchion from the slider. How else are you going to check the tubes for bends with a dial indicator? Or did you skip every single important step in the service manual?

[@Dentinvent]

True what you said .
I only wanted a new seal and my bike mechanic said the method would work . It worked so if there are tube bends the bike mechanic can deal with that .

I did it a similar way but i made a hook out of coat hanger wire and put that though the drill hole and just yanked the seal up. Used length of plastic drain pipe a bit longer than the stantions and just slightly wider than the seal, then cut a slot about 3mm wide and about 50mm long so it would squeeze into fork leg and press on outer edge of new seal then just tap it down with a mallet.

Nice. Must be many ways around it but not a lot of info on the internet .

Brave

Probably because I’d never changed one before 😊.

DO NOT do this unless you are ready to take a long time and have massive patience.
All the steps he is doing are what you would do anyway to properly do a fork seal change/inspection.
I have done many without removing the fork at all. Wheel and brakes off, good support, remove the lower bolt and seal clip, tap them out by extending and lengthening the fork leg. Install can be done with a piece of pvc/nylon pipe cut in half as a driver
This is the improper way to service a fork. If you see someone do this in a shop or even as side work, RUN

Thanks for your comments.
I did have massive patience and enjoyed changing the fork seal. It is satisfying to see the new seal does not leak now.
I never say this is the correct way to do things. It was just the way I did it and my main aim was the stop the fluid leaking out.
I assume with your method , you need to drop the fork right out to get the old seal off and to get your pvc pipe in place to push the seal down.
