OK... Took the top nut off, that released the upper tripple tree. Now there are two very thin nuts holding the stem in. What's the trick? The manual talks about special tools (thin wrenches I guess) what's everyone using to get these out? I don't NEED to get it off, but I kinda want to paint it. Thanks!

When you get the exact wrenches sorted out . . . let me know cause I want to get some. The wrenches are thin like in cone wrenches. Bicycling term for bearing cone wrenches. Thus a bicycle shop might be able to get some for you or try Bike Nashbar Deon neon might be able to tell you the sizes you need. Airguy (Keith) wrote Quote:
Those adjustment nuts are 38mm. If you do the conversion it is almost exactly 1.5in.
Bike Nashbar doesn't have spanners large enough...
Jack Lilley has them.

can get a whole set of cheap big wrenches from Homier for less than that. 1" through 2" then just take the one or ones you need and grind them thin.(better to make them thin on a shaper but not many members probably have one.I imagine Harbor Freight has some cheap ones too that you could do the same thing with. I an 3,000 miles over due for my 12,000 mile service and thats part of the service so I'll be doing something soon myself.

Let me know what you end up doing. Harbor freight is a good idea... Might take me a while with an angle grinder I really only need one thin one I suppose, since I could use a regular wrench or socket on the top nut.

What stinks about the price is that for 7 bucks you can get a 37mm or a 39mm or a 40mm easily. The 38mm is a very odd size for bearing spanners.

You should think about replacing the oem headset bearings with the sealed headset aftermarket bearings when you take your tt apart.

no. some leg work still needs to be preformed. I was hoping you could put the final touches on that search. verbage...I want to write this up but Paul failed to give me the lower bearing sets pressed race, i.e. the cone. Going to google, I found Peter Verdon's web page, discussing exactly these bearings AND replacement tapered bearings. Firstly my prefire's headset bearings are Top: Koyo SAC2647-1 Bottom: Koyo SAC3055-1 The 1995 Honda CBR600RR has the exact same bearings. The website referenced above list replacement tapered bearing and seals for our bikes (really for the Honda CBR600RR). Can you guys help with extracting the information from Peter's site? Help I ask? Well confirm this for me please: Tapered Headset Bearings & Seals Cross Referenced bearings are All Balls Bearings Top 99-3520 Bottom 99-3519 Cross referenced seals are Clark Seals Top CSL CY32005X Bottom CSL CY-32006 JR I relied on Peter's measurement for the bottom bearing set as I do not have the bottom set's cone. (pressed race). Dimensions Top Tapered Bearing Set ID=26 mm OD=47 mm Width=15 mm (verified with caliper) Bottom Tapered Bearing Set ID=30 mm OD=55 mm Width=17 mm

I used channel locks and a crescent wrench, but in this thread TomV said he used car brake spring pliers to hold the bottom nut, and used a 1 1/2" socket to remove the top nut. Here's a pic of the brake spring pliers, and you should be able to find them at any auto parts store for $10 or less.

Good idea!! So they won't be a perfect fit, but should offer good leverage.

How thin does the wrench need to be? I have these Martin wrenches and they are about half the thickness of a standard wrench

They would probably work... Not sure exactly how thin, but I think the triumph tools are actually stamped steel, so pretty thin. The nuts themselves appear to be in the 3/16 thickness neighborhood, but something a little thicker would probably work.

Got a wrench lent to me by OldRoadie today, and it worked perfectly! Used a Ford wrench for the top nut. I was a little skiddish with the whole bearing thing, but I was just REALLY careful. They are fine. Spent an hour or so sanding just to smooth it out a bit, I think it looks MUCH better. Got some primer on it too.
By the way, a dremel with a fine wire brush on it takes that powder coat off REAL fast and is great for getting the nooks and crannies.
