That count I'm definitely right on. Sheesh! Read your own subject line. You started this silly thread, Ted. > I wasn't looking for a step by step guide, I already have that.

So? You were raised by your sisters and there wasn't much male influence in your formative years? Does that explain all this hysteria you're posting?

Oh, you are SO superior, Ted! But *why* are you jerking our chains with question about " a quick and dirty way to do fork seals without a press?" Any pragmatic home mechanic knows how to build a simple tool to do that simple job.

Well, fair enough, but a quick read suggests that that's pretty much the procedure I've used on '81, '83 and '86 Hondas with no problems. I suppose the '80 CB750 might be radically different, but it seems unlikely. (Except I wouldn't call it "pulling" the stanchion, more hammering it outwards, if you see what I mean. Impact needed to drive the top bushing and fork seal out.) -----sharks

I've done this successfully many times. It sometimes helps if there's a second person handy to twiddle the nut the first few threads while you push it down. -- Trophy 1200 750SS CB400F CD250 Morini 500 Sport GAGARPHOF#30 GHPOTHUF#1 BOTAFOT#60 ANORAK#06 YTC#3 BOF#30 WUSS#5 The bells, the bells.....

Jim says: I hold the cap down with one hand (supporting most of my 205 lbs with that hand) and turn the fork tube with the other hand to thread the cap on. This is easier for me than having to readjust my grip on the cap as it screws into the tube. The only thing that I have ever used the press for in rebuilding forks is (if I only want to replace the seals and change the oil) to push out the seals. To do this, I: a. remove the circlip which retains the seal. b.remove the cap and fill the fork (extended) with cheap oil. c.compress the fork with the press (with the bottom of the fork sitting on a block of wood in a wash tub and a rag wrapped around the fork at the seal area), which causes the oil to push the seals out of the fork legs. .. |
