Fork seal cleaning tool

Postby John Hilmer » Sun Jan 27, 2013 1:57 pm

Folks,

Sometimes it is possible to clean the front fork seals enough to stop a leak. If enough soil builds up on them they weep.

Cut a piece of the milk or water jug where the radius is similar to that of the fork tube like below.

Insert this into the forks and rotate it around the tube a couple of times. While it won't cure a torn seal, if it is just a build up of soil it may restore the function.

Quick, easy and cheap, and best of all effective when soil is the problem.

Folks,

The soil you see on the plastic came from one of the forks on the VF 500 F. It had developed a weeping leak, actually both of them had. I cleaned both in this way and put on about 40 miles and returned home dry, so it worked on this one.

Nice application of a plastic bottle. Back in the old days we used 35 mm film, I have also used a .0015" feeler gage. Someone makes a little bit of plastic and actually sells it as a tool, but the company escapes me at the moment.

That little piece of plastic is called Seal Mate and comes from Motion Pro.

As long as we're on the topic of fork seals and improvised tools, I installed new seals in my project '04 R6's forks with an old shop vac extension tube recently :) Twist on the old PVC pipe trick for that, but it was free because it was amongst my hoarder's junk.
