Ok I am not the brainiac How to guy, But I do like to see pics and gather tips. here is my how to on the Transfer case oil change I did on a 07 102 Yours will be similar.
Tools you will need, 1/2 drive ratchet, extension, 13mm short socket, I used a large washer covered by some paper so as not to scratch chrome when turning Fill Plug.... and who the hell knows what Allen wrench that is for the Check Hole?
This is how much Transfer Case Oil you will need. right from OM. Any Questions? 1 US Qt. will get you two changes.
This is spec on Oil right from the OM any debates? Plenty in a search to read.
In debates, It was determined Not all GL 5 can meet GL 4 Spec. So be careful what you use. Be sure it meets GL 4 Spec, This Lube does both and says so right on the container.
It also says good for Motorcycles, so, of all on shelf this was only one that said GL 4 and good for motorcycles, it was 2X's more expensive than Mobile One at $15.99 US dollars on 3/28/2009 At Auotozone.
This is what I landed on. Royal Purple, yes sir, nothing but the best for the Amsoil dealer!
First find out how bad a shape you are in now, Bike must be very level for a correct reading, on the kick stand won't get it, on a jack on a level surface will. Then remove this plug with proper size Allen wrench and some fluid should creep out. That means you were good. Large marked hole above check hole is fill hole.
this is Drain Plug hole right side of bike folks, just above brake line in SIDE of transfer case, not bottom. A 13mm socket will remove this.
This gives you a better shot at location.
Ahhhhh I wish I read here somewhere I should have had a crush washer handy for this job, but I missed it somehow so I had to re-use mine even though it is against my religion. (Whatever that is)
While the Warm oil is draining, remove the Fill hole plug with a large washer with some tape or paper over it so as not to scratch your Chrome.
Pic of three plugs you have cleaned and set aside where you will kick it into the drain at some point.
Ok now re install the drain plug after all fluid has drained out. Pay attention to the torque, it's not nearly what you you think it would be. I bet it would be easy to strip, so get your torque Wrench out I forgot to mention.
While we are on that subject the Check Hole requires even less torque! (but leave it out just yet.)
Now fill using the Gear Lube you choose with every ounce of your conscience. (Whatever your heart desires)
When it starts to come out the Check hole, your there! Now put check hole plug back in for now and give it another little bit of Gear Lube.
Now put the fill Plug back on and Run the bike a Bit in gear. I did mine on the jack, but I like to live on the edge, nothing that is almost as thrilling as a good ride than Sitting on your bike aimed at a steel door and running through the gears and watching the speedo top 80 and wonder what would happen if this thing falls off the jack right now! You may want to try it. Anyways, Spin it a bit and re check level through the check hole. Fluid should be at bottom of check hole with bike level side to side and front to back. (worry more about side to side)
Now take her for a 10 mile spin and re torque all the plugs to spec. I would not skip on this. And I would re check in 50 miles.
This is a 15 min Job, You should never pay to have this done. It's a 10th of a Wrench in difficulty.
