I had pics but haven't found them yet.
But I used the level hole small allen, and after draining used the level hole with oil pump can to put fluid in.
I just hit my 600 mile mark on my raider and now its time for the dreaded gear oil
I heard from every one that the pipes must be removed , thats not true i just did mine
and it was easy ,
first off what drain plugs are what , the drain plug is on the side of thetransfer case
hidden behind that ulgy foil crap , so use some pliers and unclip the zip ties,
the drain plug is a t-40 torx,
next is the fill plug this is the big silver plug on the side to remove this i used a
10mm allen that i cut to about 1 1/2 inch and i used a 10mm wrench to turn
now for the little level plug this is the allen bolt under the big fill plug i used a 1/4 inch
socket with a allen made for my drill gun .
so dont remove your pipes . drain the transfer case and plug it back up
now fill with .58 quart sae80 api gl-4 hypoid gear oil (per the owners manual)
fill in the big hole untill the little fill level hole starts to drip .
please pass on this info .
