  1. The climate is the cause for their early demise. Road salt, temperature fluctuations below and above freezing point, condensation, grit etc. Move to a dry and warm land and your wheel bearings may outlast you. My solution avoids costly relocation and ensures bearing seal is wettet in grease and wiped clean whenever I inject grease or oil. Got a poor seal on one front bearing where over greasing wets brake disk. Still no problem after nine years in service. Replaced both front brake discs a few weeks ago after about nine years in service. Only 0.5 mm under size but brakes were still fine. These discs had been off the car a few times to remove built up rust resembling Saturn’s rings.
  2. There are several threads about unSmart wheel bearings. Here are two: Front bearings Rear bearings Both mods described in above posts were done more than ten years ago and I have not yet changed any of those bearings. No unbearable bearing noise and my Smart has clocked 250,000 km. Proof these mods work.
  3. My grandmother told me a woman if attacked by a bear can bare her bum and bear will become bashful and quietly walk away. Not so many bears any more around here so not much chance to test this method but my mother still carries a whistle that she keeps blowing in to announce to bears she is about. Just wonder if you Canadians have tried baring your bums in the presence of bears and whether this had any effect on the bear.
  4. Grass not green. Why?
  5. The method allegedly only works for women with proper child bearing hips. Not yet proven if method works for cross dressers. Willy may want to try?
  6. I hope to take mine all the way to the Moon. Have so far covered 2/3 of the distance.
  7. Mine has just passed 250,000 km.
  8. A few photos of my DIY auto knob: Nylon 66 button. Momentary switch soldered to home made circuit board. Cable from switch to SE drive is from an old Nokia head phone. view inside knob. The botton pin that makes contact with switch is just visible in right hand side of photo. Botton is sprung outwards with short length of carbon brush spring. Botton bottoms out in knob and cannot overload and damage switch. This is a mod I made ten years ago in 2007 and has stood the test of time.
  9. Electronically the pedals are just the same. Kickdown pedal for the automatic has a 2nd spring which gives driver the feel of kick down. I converted mine to auto myself. It uses the standard pedal and works just fine. Made my own auto button too. Turned it on a lathe out of white nylon 66. A standard bell switch will work equaly good as would any momentary switch but nice to have switch fitted on the gear knob. I'll post a few photos later.
  10. Book contains about 205 pages. Blick ins Buch allows you to read about 38 pages.
  11. Those sufficiently Smart can read these manuals online. Unsure if below link works. If not try this one and click "Blick ins Buch" Zum Glück war ich während meines Deutschunterrichts in der Schule wach und kann daher Deutsch lesen.
  12. SAR dog training?
  13. Not sure if you can code cruise control on the later models. Seems like you need to be networked to MB in Germany to do the simplest thing.
  14. ABS in Delphi only works for older Smart cars like mine.
  15. These sprockets are flame hardened. Some sprockets obviously bypassed the flame hardening process without anybody noticeing. Easiest way to check sprocket hardness is by using a sharp file. Compare with a good sprocket. File should not bite if sprocket is good.
  16. No point hardening these toothless sprockets now. Lucklily mine still has its teeth intact just like me.
  17. Of course I never bother cleaning off the protective grease on new discs. Took the Smart for a quick spirited drive testing and bedding in the brakes. Passed the annual motor vehicle test shortly after with flying colours. Was told my Smart still looks like new underneath. All rust well hidden behind tons of black bitumen.
  18. Changed my brake discs first time in twelve years. They were getting thin measuring only 7.5mm thick which is 0.5mm below the minimum. The new pair of discs only cost me £22, pads included. Decided not to renew pads at this time as still a few mm remaining before they are worn down to the backing plates.
  19. Some disagreement between the two sensors. Check wiring again using my method. Remove and check smoothness of shift drum turning angle sensor using a multimeter set to read Ohms.
  20. Removing the whole EGR valve from the 450 Cdi is a very complex and time-consuming procedure, which is strictly not required. You can remove and clean EGR valve in situ by removing actuator and steel valve cartridge from aluminium housing. Removing cartridge is made easier if you have in your possession a suitable tool that can turn cartridge and break it free from soot and hard deposit inside housing. Removed cartridge after cleaning using elbow grease and Mr Muscle Oven Cleaner. T25 Torx bit, 1/4" ratchet with short extension and special home made tool used to rotate and break free cartridge in housing. I have later been advised the bolts actually have 4 mm Allen heads. T25 Torx bit is therefore not the right for these small bolts and will damage the heads and make it difficult to fit the right 4 mm Allen bits. The area where the tool fits measures 28.09 mm in diameter. The slot is 5.85 mm wide. ID of tool 28.25 mm and width of tooth 5.6 mm. Tool is also guided in aluminium housing. You have to keep twisting cartridge until it moves freely and can be pulled out with pliers. I have drilled 6.5 mm radial holes in my tool so I can turn tool using a screwdriver. Exhaust inlet into valve cartridge. Exhaust outlet from valve cartridge. Exhaust flows out of the slot in above photo and out of its tip, see photo below. Close up view of seat and disc. Note that seat is serrated and burnt. It may be possible to repair by machining but cartridge can’t be easily disassembled since valve at end is TIG welded to valve stem. This valve won't seal but no major problem since I've blanked off exhaust supply at exhaust manifold. View from engine space and EGR valve aluminium housing with actuator and internals removed. Valve cartridge fits with slot facing the lower bolt hole (the most inaccessible bolt). Blanking off exhaust supply to EGR valve will ensure there is no need to open out and clean in the future. Tool is made from a brass pipe fitting. Its tooth is stainless steel and silver brazed to slot filed in pipe fitting. Tool is turned down to 39.3 mm on the OD where it is guided in aluminium housing. One can chamfer the cartridge as shown in below photo but diametrically opposite slot (12 o'clock, 6 o'clock is position of slot). Initially I chamfered 60 degrees anti clockwise from slot when viewed from actuator side but found that was no good due to my chisel interfering with car body. A sharp chisel can now be wedged into the chamfer to pry cartridge out making next time EGR clean a whole lot easier and no need for any special tools that are unavailable unless you make your own. Those lucky to have access to a metalworking lathe can chamfer the whole circumference but leave at least 0.5 mm of land.
  21. Housing is intact so can be reused. A big problem over here is the mounting lugs drop off leaving actuator dangling from its lead and the poor owner asking me why his Smart does not run. Have seen that many times now.
  22. In fully extended position the clutch diaphragm pushes hard on the rod making work easier for clutch actuator motor to drive rod back to retracted position.
  23. Spring inside actuator holds mechanism in its retracted position. It works very much like a toggle.
