FE 501 2002 - Front Tire/Axle Repair/Refurbishment

Hi folks,
just wanted to share some Husaberg 2002 front wheel repair stuff. The last time I checked my front tire I could feel some play in the bearing-axle-parts. Anyway, the bike is already 15 years old (Husaberg FE 501 2002), I don't know how many hours it made, what the bike was used for in the past and if the first owner ever exchanged parts. I decided to do it now. Actually it's not a complicated thing - maybe somebody will find this info somehow useful...

The front tire was available with or without mechanical speedometer. That's why there is two different types of wheel hubs, one symetrically (37mm sealing on both sides) and the other one with
37mm sealing on the brake disc side, 52mm on the speedometer side. Since I'm planning to use an electronic speedo with the magnet mounted in the brake disc, I want to remove the mechanical speedo. Actually it is broken (plastic housing), looks ugly and causes dirt entering the sealing. There are also some serious cracks in the speedometer housing, the rubber sealings for the bearings are old and hard. Enough reasons to do something about it.

Before ordering anything I checked all parts, especially for wear and play. I my case I decided to replace everything (not only bearings and sealings, but also axle, spacer tube, spacer bushing and axle nut).

I ordered the following parts from my KTM supplier. (images also with article numbers):
  • Spacer Bushing 20x26x27,8 / 2000 (50309012000): 4,88€
  • Nut Front Axle M16 / wrench size 27 (50309082100): 7,85€
  • Front Axle USD43, 185mm, 2001 (50309081200): 31,36€
  • Bearing Spacer Tube Fronthub 20,5x25x63,3 (50309011100): 5,71€

In my case the Husaberg shares many front axle parts with older KTM models (two strokers like SX, SXS, EXC, and LC4, EXE). That's why there are still new parts available. In case you cannot find the parts at your KTM dealer site, try out a Husky-supplier/Husky-dealer site and add "-HVA" to the end of each article number - works somehow in Germany.

Sealings, bearings and shims I ordered from a local bearing supplier:
  • 2 x SKF 61904 2RS: 13,70€ each
  • 1 x shaft seal ring 26x37x7: 1,89€
  • 1 x shaft seal ring 40x52x7: 2,77€
  • shim ring 40x50x0,15: 0,20€

The ball bearing with the number 6904 is somehow obsolete - replacement is 61904-2RS.

When installing the bearings be careful not to damage them. Do not bring forces against inner and outer ring of the bearing at the same time! You can take off the brake disc, heat up one side of the hub using a hotplate or hot air blower and carefully press the bearing into the hub, using little force only on the outer ring of the bearing (e.g. using a socket wrenc and soft hammer). Install the circlip. Center the bearing spacer tube using your axle and install the other bearing the same way.

Since I would like to get rid of the old mechanical speedo, I found a solution from a german company, called "WP-Spezialteile". The make an adapter spacer that one could use instead of the old speedo.

It's made from aluminium - I also measured the part. Pictures attached below. I'll update this post when I fitted the part.

If you have access to a lathe you can also use a shaft seal ring 26x52x8 (width 7 is not available) and make yourself a spacer bushing like the one for the other side - with slightly different measurements.

I've bought one of those before - almost certainly from the same supplier. They also do one for the even earlier 17mm spindle (got one of those too!)
