front fork tube rust pits

Postby lbman » Sat May 07, 2011 8:02 am



OK Guys,
Just what does a person use to fill in Pits on the fork tubes.?
I had to replace my bent forks . picked up a pair from a buddies wrecked wing yesterday. but it had been sitting for years had lots of rust pits. I used a file to take off the edges. but if I run my hand over pit's they do not feel smooth!
Could I Solder them and file down?
thanks

I have seen this done on Hyd. Cylinders Rods that were pitted & it did stop the leaks & lasted. Solder in the pits and take emory cloth to smooth out the solder & install new seal kits. Worth a try. Good luck.

I've heard of people using JB-Weld, putting it on to fill the pits, and smoothing the rest off, so all that remains is what is in the pits. I can't see a reason why that wouldn't work, I'd be tempted to try it myself.

thanks,
I will try Solder and JB Weld.. I will take some pics and post them.
I left the old seals on the tubes. they felt and looked good. plus, if it tore them up I wouldn't feel so bad. I think this will be one of those," Time Will Tell," Posts.
One Thing I have going for me is the Progressive Springs. I Won.t be running Max Air Pressure.
I've used progressive springs before on my BMW R90. I was Impressed. Put the bike up and inch. No More Diving front end when braking.
With New Springs front and back and OMG straight Fork's. I Will have a new Bike.
Thanks to all your Help. It's nice to bounce things off folks Who understand.

Re: front fork tube rust pits ate seal.

Well after putting on 100 easy miles back and forth to work and checking nuts and bolts I figured it was time to take the back Ruff Road, home on a hard ride. Dang it fork with rust pits started to leak! Go Figure. I will order new seals, try to straighten fork tube and swap it out.
my buddy from work builds race cars and says He can straighten it! NO PROBLEM. will be easier than trying to fix Pits. I believe. but while I am waiting for seals I will try soldering and JB weld just to see how it goes.
I have read a couple of posts that stated not to use as much fluid if progressive springs are installed.
Any Fact to this?
I did put in a couple of pounds of air. I will see if it held. Doubt it! and run No air.
Looks like I ain't done working on bike Yet. I get to practice taking apart front shocks on my old bent one. cant hurt nothing on that.
manual says to take that year of shock to dealer. special tool? I will try the regular method I've seen in these posts
any input sure appreciated.
