Sealey Ms016 Fork Seal Driver

Product Information

First, buy a section of thin walled pipe that is slightly larger than the diameter your need. Next, cut it in half/down the middle (top to bottom in the picture above) – the result should be two C shaped sections. Finally, clam shell them around your upper fork slider and secure them in place with a hose clamp. The hose clamp should be on the end of the fork seal driver furthest from the seal being driven – this will keep it out of the way as you are driving the seal into place. I have made a small video showing the 'hard bit' ... driving the new fork seal into place ... which shows how easy it is using home made tools. To drive the seal down I use a cut down plastic drain pipe as a slide hammer. Get a plastic drain pipe at least maybe three times the width of a hand, ideally more.

Not all upper and lower fork slider tubes are the same diameter, so this is going to take some patience on your part when in your local hardware store. If you can’t find something off the shelf like I did with the PVC coupler above, there is an alternative. Make sure the fork is pulled apart ¾ of the way, and wrap the lower fork with the paper, and tape in place. It did take a proper tug (oooer missus) ... thats why I mentiond to "not be afraid to give it some abuse" (or words to that effect). Rather than cutting it in half, in the past I’ve just ground down the outside and inside. The outside is fairly easy with a bench grinder – just push it against the grinder wheel enough that the seal spins fairly slowly with the grinder wheel still spinning fast. Then use a die grinder on the inside while clamped. Take fork upper and coat the seal mating face with seal grease (not normal grease). This is important as it will prevent the seal degrading and also the aluminium of the fork upper corroding.Ideally you’ll have used a section with a properly flat bottom, in which case you should be able to just drive straight down with a ‘slide hammer’ action (read wanking ), if it’s not properly flat at the bottom, you’ll need to keep turning the fork after each drive to ensure it stays evenly pushed down. Laser Fork Oil Level Setting Tool Setting the fluid level in front forks accurately is critical to the safe handling of your bike and this tool makes it a piece of cake.

Loosen top yoke pinch bolts – Keeping the lower yoke bolts done up – This allows you to easily undo the top cap on the forks. At this point it is important to note / write down how each part fits together – As you will be cleaning them all later on.Take off the top cap - Remove inner damping rod – It will slide out as you tip the fork oil out – And remove fork spring. It will feel as if it is catching on something and is unnerving at first – But this is simply the internal bushes/washer hitting the fork seal. Gaffa tape is like "the force" - it has a light side, a dark side, and it holds the universe together. Clean forks thoroughly before taking forks apart – This makes it easier to stop mud and grit getting into the fork internals when they are apart.
