  1. Fitting Mousse's with a guide to proper sizing and selection to suit a particular tyre and what lube to use and how much.
  2. What Have U Done To Your Bike This Week

    I made up a dedicated cradle for the top of my jack this week, found it hard to swing on spanners with the bike moving around on me.
  3. Axle bearing question

    Contact seals Radial shaft seals are contact seals that are used, above all, for sealing oil-lubricated bearing arrangements.. These ready-to-mount elastomer sealing components normally have a metal reinforcement or casing. The sealing lip is usually a synthetic rubber and is normally pressed against a counterface on the shaft by a garter spring. Depending on the seal material and medium to be retained and/or excluded, radial shaft seals can be used at temperatures between –60 and +190 °C. The contact area between the sealing lip and counterface is of vital importance to sealing efficiency. The surface hardness of the counterface should normally be at least 55 HRC and the hardened depth should be at least 0,3 mm, the surface roughness to ISO 4288:1996 should be within the guidelines of Ra = 0,2 to 0,8 μm. In applications, where speeds are low, lubrication is good and contamination is minimal, a lower hardness can be acceptable. To avoid the pumping action produced by helical grinding marks, plunge grinding is recommended. If the main purpose of the radial shaft seal is to prevent lubricant from leaving the housing, the seal should be mounted with the lip facing inwards (fig 9). If the main purpose is to exclude contaminants, the lip should face outwards, away from the bearing (fig 10). fig 9 fig 10
  4. Axle bearing question

    It wont make much difference to me as I dont ride that often or far. When I install seals arse about in certain kinds of pump I always pack the spring groove with Coppercote and this seems to protect the spring from corrosion. Sadly I wont be doing it this weekend as the bearings and one seal in the All Balls kit I got are right but the other seal is the wrong size.
  5. I am about to change the rear wheel bearings on my WR250 Husqvarna and I am after opinions as to which way to orient the lip on the seals. Working in the mining industry I rebuild machines that must endure the most severe conditions and years ago I was instructed by an Engineer in the Pilbara to fit seals to bearings in housings with the lip (spring side) to the outside as it was more important to keep moisture and dirt out than it was to keep the grease in. Not possible when with such things as gearbox oil seals as the oil will come past the seal. I have not looked to see which way they are currently fitted but my guess is the lip faces in.
  6. Ignition Diode Question

    Thanks for that, l suspected it may be more than just a diode, l shall keep an eye out for a wreck. This might do the trick as it looks identical, I searched regulator instead of diode.

    I made up some new Stainless Steel axle adjusters for the Husqvarna WR250 as it came with both jacking screws broken off in the swing arm.
  8. Ignition Diode Question

    l reckon the one I put in would carry much more current as it is physically about 4 times the size and has heat sink fitted, if I can find a replacement I will but no luck on ebay unless l want to pay $189 plus postage.
  9. I am almost embarrassed to admit it but one of my bikes is a Yamaha AG100. It stopped running on me last week and after noticing no spark I traced it to a broken terminal on a diode mounted under the tank. I only had a much larger industrial diode on hand complete with heat sink so I mounted that in its place. Is the broken diode only a diode or is there something else in the epoxy? The bike runs again just dont want to cook something.
  10. bike rack clamp to stop rack shaking.

    If I was designing and making one I would prolly work it so it pulled diagonally into a corner, I have found that clamping 2 box tubes together works best when the clamping screws push the inside box into a corner. I would make mine using at least 10mm threads and High Tensile if possible.
  11. Hi to all out there, I am getting back into riding the dirt after a break of 30 years. I have a Husqvarna WR250 that is about as worn out as I am and I hope to find some folks to ride with from the Ballarat area. I have twice ventured out into the Enfield State Forest alone as I can ride there from where I live but felt a little insecure alone far down some narrow trail not sure where I was and up the fuel tank in ruts. In my youth I rode Enduro's and Desert Races and my last big ride was the Birdsville Track but these days I would be happy just to make it back to the trailer in one piece.
