Like I mentioned earlier, as an option I believe I found the best combo possible for the ball diff WITHOUT using the new diff adjuster.

Use the 46T FPS diff pulley (801395) or the 47T one (808396). You can leave out the 3 steel pins. The diff pulley seals the balls away from dust and dirt very nicely. You need to use the balls from the FPS diff which comes from the 15 x 28 x 9 thrust bearing (1374). Pop the balls as per the instruction at mytsn.

Instructions to build the ball diff so that you can adjust it externally WITHOUT the use of the new external diff adjuster is as follows;

1. Put locktite 242 (blue) on the threads of the long Diff axle (right side) (801432) and NOT on the diff adjustment screw (left side) (801433). No locktite on the grub screw (1259) either.

2. Assemble back the diffs without the grub screw (1259).

3. Leave the diff assembly for an hour or so for the loctite to cure and put the grub screw (1259) back in the right long diff axle (801432) to keep dirt out.

4. To adjust externally, make sure the left side of the diff axle (801431) and the hole of the diff adjustment screw (801433) align so that a 1.5 mm allen wrench can be put through the holes. Turn the right wheel to adjust diff setting. Clockwise to tighten and anticlockwise to loosen.

It doesn matter which pulley since they are exactly the same in thickness and size to mount those diff balls and 3 little screws. I think Serpent did modification on the externall diff adjuster itself (later production batch maybe) to host that diff plate since it would not wise for that plastic diff adjuster facing directly to the hard diff balls. I guess I need to permanently glued the plate with the diff adjuster.

Thanks for your reply.

This time, I think Serpent wrongly named their new External Diff Adjuster.
Should be Diff Cover Adjustable!!
Because, no matter what kungfu you are using to build it, when you tighten the adjustment screw it makes no diffing action for rear left wheel.

But it will cover your diff nicely.. and does not make your diff easily let go.. this word is being popular since Mike Myers keep on using it in his Ohio WC report.

BTW, Serpent should make it for both sides. So you we dont need to replace the diff if we want to switch between ball diff or solid axle.

Opphs, I forgot to add that the instructions above are a compilation of tricks from EVOLUTION and Proficar403.

I have not tested the external diff adjuster myself. Since I have successfully used the FPS diff pulley (acts more like a shield cover to the ball bearings because of the lip design) on the ball diff and used loctite on the ball diff as per the instructions, the ball diff does not "let go" even after I adjust it externally.

TP06 (=NRS52607) muffler in-line set, has anyone tried this? please kindly give comments. Thanks

Pyramid - I have it and it works wonderfully.

Look who's a "tech elite" now! I am probably going to try the FPS pulley trick.

Well, I give due credit when credit is due...

The FPS pulley will not have any side play and wobble like the stock ball diff pulley. I don't think you'll have problems with the belt slipping off too.

InitialD

You mean TP06 Outlaw = 52607 and TP06 EFRA = 52606? Are you sure they are the same?

EVOLUTION

I will take credit for sharing the info but the ultimate credit has to go to the author whom was a excellent local racer.

n1technik

any word on new 705?

I think you and me and almost everyone else here are holding our breaths and checking mytsn daily for a possible release, but in reality we don't know if it's this year or next, so I think we will have to be patient....
