Exclamation Taking on fork seal replacement procedure

I've looked everywhere for videos on how to replace the fork seals and I'm pretty confident that I'm ready to tackle the task. My only issue is that the videos I've watched only show the procedures of dismantling the forks itself, getting to the seals and reassembling.

My issue is that I don't know how to get to the forks themselves...

Would anyone have any video links of step by step videos of how to actually get to the point of getting to the forks? It'd be nice to know the step by step procedures of taking off the wheel, brakes, body, etc etc etc.

Help someone?

Would anyone know exactly how much fork oil I should put back into the forks? I have a 1999 Honda CBR900RR.

And some suggestions on which lifts are best to purchase to do repairs/maintenance would be great, too.

Gratzi.

I cant tell you how much oil to put in BUT, i know it is a specific amount so be tedious. ( i wanna say around 13oz but DO NOT quote me on that...lol) It might be nice to pick up a shop manual if you plan on working on the bike like this. Its no video tut but it damn sure shows you the assembly of the bike. That along with some common mechanical sense and you should be able to get it done.

Pitbull stands are good, yet put a dent in the wallet. As far as a bike jack idk.

On the post 2k bikes i think the disassembly is a two person job? Bueller? Bueller? idk about the older ones...if you have had no luck here, perhaps do a couple searches over at fireblades org if you haven't already.

Good luck!

Thanks for the heads up revilingfool. I might call the store where I bought my parts from and see if they're able to help me out with the amount of fork oil. Alls I know is that there is an exact specific amount I have to put.

I saw on a thread (forgot which forum) about a guy who screwed in I-Bolts to the ceiling and used ratchet straps to suspend his bikes. I already have the straps and I-Bolts are pretty damn cheap. I might go that route. Hopefully there's no major swingage while it's suspended like that.

I actually found a video of how to get to the forks. But his video was recorded after he already went thru the whole project of getting to the forks and he just basically summarized his whole process.

Thanks for the reply!! Fun fun project this Sunday!!

Getting the forks out is the easy part, currently my bike is sitting on a jack placed under the front of the exhaust manifold, and leaning on the sidestand, Seems stable enough. The free manual downloads give a numbered step procedure on how the get the forks out. But its pretty strait forward so i did not need it.
Its the forks themselves that gave me greif, and are currently at the shop.

@RedBaron

Hey thanks man. I looked around for a download of my service manual and found one available. I was trying to read how much fork oil I need and I read how much I need but have no idea what the hell it's telling me o.O

Here's what I'm reading:

FORK FLUID CAPACITY: 561 ± 2.5CM³ (19.0 ± 0.02 US oz, 19.7 ± 0.09 lmp oz)

Then underneath it says:

NOTE
- Be sure the oil level is the same in both forks.

FORK OIL LEVEL: 114 ± 4MM (4.5 ± 0.2 in)

O.O Can someone decipher this for me, please

Your welcome,

you will need 561ml each side,

The Fork oil level is the the air gap- distance from the top of the fork to the liquid= 114mm + - 4mm

you can also make a simple tool to measure the oil level in each leg. My Clymer manual lists a spec for the oil level once springs are reinserted - if you swap springs, they could have a different displacement, in that case you need a fork oil level gauge.

I made myself one from a wooden ring I cut out of scrap, a legnth of brass tubing, some silicone weedeater fuel line and a syringe.

Basically the brass tube you measure the distance below the ring down to the spec that the manual states. You add your oil til you think it is to the bottom of the tube, then use the syringe to remove oil til it quits sucking it up. do it for both legs and you should be equal.
