Gentlemen, this is superb information
You learn something new everyday.
Thanks Proficar. I knew you still had much information to share with us even though you're not running the 705
Thanks to EVO too for affirming and providing the information
EVO, I think for the Serpent ball diff, the right is left and left is right for the description you wrote, right?
Ok, this is what I have summarised as below from the postings. Correct me if I'm wrong.
1. Put locktite 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.
Ok, the last question is after doing the above, do you still screw in the grub screw (1259) tightly to lock the diff setting or just snugly screw the grub screw in? Modellor would put it in but Proficar does not use it. I think screwing in the grub screw (1259) tightly will make it difficult to adjust the diff externally as outlined in step 4.
