08' Honda 400ex, loose rear brake rotor/axel lock nut & collar

Recommended Posts

I have an 08' 400ex, and have some issues with the rear brake rotor and axel lock nut. The rotor has almost an 1/8 of an inch of play both left to right and up and down(i tried to tighten the allen bolts that hold the rotor to the hub, they are tight), and the axel lock nut and "collar" (the piece to the left of the nut, w/e it may be called) have a bit of play as well, yet they are not loose enough to be spinning on the axel. Both the nut and the "collar" are moving, but they are still together, with no play in between each other. What could this be? axel bearings? bad threads on the axel?

I know on my 450r, there are two nuts that on on the threaded collar. Make sure the outer (one closest to tire) is tight. Then snug the "safety nut". Maybe get an antifade locknut/brake hub to eliminate the stock locknut assembly.

i have had the same problem on my 400ex and i put some rtv sylicone on the threads and it keeps the lock nut from backing off ... and the spaces tube in the housing can also cause it to move if it has some ware on it ...

I replaced the axel in my son's 05 400EX. I used some thread locker on the threads and used two large wrenches on the nuts to lock them inplace. Good luck.

      I have a 1988 Kawasaki 220 bayou. I removed the skid plate and misplaced the 4 bolts. Anyone know the size of these bolts, 3 dealers could not find any information. Can you please help?

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
       
      Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
      Are my valves siezed or not working properly 
      or is my timing off causeing valves to not open in correct order with fire 
      PLEASE HELP all help is appreciated

      I loosened the allen bolts on the carrier and when I went to put my driver in the alot to pull back and tighten the chain, I noticed the holes were facing the front of the bike. I tried to slide a driver in and tighten the chain but the thing would not budge. I nearly ripped the tip off the driver in the slot. Any suggestions?

      Am i better off to just replace the bearings or buy the whole carrier?

      Anyone know a place i can find a used stock pipe for a 400ex?  I would love to find a take off

      The title is for attention. I’m prepping my cylinder head off of an unknown year 400ex to install on my quad. And I’m examining it and there’s literally a Jewish start( Star of David) protruding from the metal on the camshaft side of the head. It’s not imprinted or etched/ engraved. It’s coming out of the metal. DOES ANYONE HAVE INFORMATION ON WHY ITS THERE??? I’ve attached a picture
