Outlander 450 4x4 seal blowing? This may help

Recommended Posts

Have you ever had your 4x4 seal literally pop out of the 4x4 housing on the Outlander 450?  You will want to try a simple fix to keep this from happening.  First, get the old seal out and clean the seal surface on the 4x4 unit with brake cleaner.  Take your new seal, and remove the spring.  Untwist it and clip off a half a centimeter or so of spring.  Don't clip off the wrong end!  I do this because these seals fail far too often and this seems to fix the issue.  Put it back together.  Tap seal into place.  This is where you get creative.  I was able to cut pieces of shelving metal that clamped against the 4x4 unit to prevent the seal from popping out and holding them in place with zip ties.  You can do whatever you think you can pull off with what you have on hand.  Just get something on the 4x4 that holds the seal in place on opposing ends.  Oh, and always replace the yoke o-ring.  Those never retain their shape and will cause leaks if you do not do so.  Inspect the wear ring on the yoke and replace if you can feel a fine groove where the seal rides.  Remember to use RED locktite on the yoke bolt and tighten that bolt tight as ****.  This is the one that always comes off during abusive riding.

      I just bought this thing and got the carb all cleaned today and it was running like a champ. There was a spare hot wire hanging down that was not hooked up to anything. I found it when I took all the covers off and did the carb work. Unfortunately I forgot it as well when I fired her up after cleaning and replacing the carb. While I was running her, the wire was lying across the exhaust pipe. The exhaust got hot, melted the insulation and next thing I know I see sparks flying everywhere Bike immediately shut down and all lights went off. I have nothing on the console now when I turn the key over. I fear I have fried my ECU. I found one fuse back by the box, a 30 amp, but it was good. Are there any other fuses on these things? Is there a way to test the ECU? Could it be the rectifier or voltage regulator?

      hey so never ran into this before but i recently got a 04 honda rubicon 500.  bought it from my doctor not running and the front brakes were locked up.   cleaned the carb and it fired right up and runs great.  these model atvs have drum brakes front and rear.  not a fan.  lost all brakes on this one when i hit some water and it got inside the rear drum case.  so i ordered new shoes for the rear end no biggie.  front is more complicated.  has hydraulic drum brakes not sure who thought that was a good idea but the pistons in the drums rusted and locked up from it sitting with moisture in the drums.
      so i had a choice to make- 1. buy new brake pistons ($120 for a set of 4) or 2. order super atv's disc brake conversion kit for $250.  i HATE drum brakes so i went with the conversion kit.  it said it was easy to install with no specialty tools.  so i order it and turns out i have to press the studs out of my hubs to get the disc on.
      anyone ever done this and if so how?

      I think my rear brakes are stuck.  Is these parts in the right position?  Any idea how I repair?  I have to give it more gas to go and I can't push it when it's in neutral.

      I've had a seriously annoying time trying to deal with the brakes on my rebuild. What size is the fitting that screws into the inverted flair cross and into the caliper? I plan on trying to make parts I need with braided steel hose.
