RE: What is needed?
RBH her are the steps that i took to get this mod done.
Step 1
You must have three diff housing colars per differential.
Step 2
Disassemble suspenions system down to the bulkheads.
Take a dremel or sand paper and sand the inside of the
collar until it fits snug onto the losi 1\8th diff.
you must cut off the ears that are on the collars also on
two of them. Take your third one and do the same thing but
do not cut the ears off.
Step 3
Take your bulkheads and sand the hole where the diff sits
and sand it out so the collar on the diff fits in snug inside
the bulk head. You do the same for both sides of the bulk heads.
Then you take both bulk heads and slide them over the diff.
Now you take the collar that you didnt cut the ears off and cut
an angle in the ears so they fit inside the hole on the bulk heads.
That is all there is to the diff conversion.
Step 4
This is where it get tedous. Now its time for the drive shafts.
As you know the cups on the losi diffs are about 1\4 of an inch
to short. I came up with that fix, i had the THS drive shafts on
my Maxx so i took those off and took the drive shaft apart. I took
my muggy drive shafts apart also. I took the THS cups and grinded the
inside of the cup out until the muggy shaft fit inside of the cup. Its
not much at all. Now you can either put them back together with the THS
pins that are holding them together, or you can drill them out to fit
the muggy pins they are also just a little bit bigger also. Then you put
them back together make sure you use loc tite when you tighten the grub
screw. Then you are ready to go. The only thing i havent done yet is use the
shafts that come with the big block kit to see if they fit on the input shaft.
But that should be just as easy as the rest of it.
