Too much slip

[What's_nitro?]

Is it possible the diff body isn't threaded far enough to allow full travel of the tightening ring?

It was greased well and tightened easily, it is tightened so that the springs are almost perfectly flat. The ring is so tight there are only threads on the bottom half of the ring. There is absolutely no way to tighten it any mroe than it is now so if thats the only solution this will not work for me at all.

It could be a possibility.

only possible if the slipper side(large) endcap isn't completely tightened flat to the diff cup(this would also result in a leaky diff of course). Everything is sized to allow assembly with minimal spring tension and also allow full tension when tightened - the nut will partially disengage the threads when fully tightened, but will not thread itself completely off the threaded portion of the cup.

Given it was designed for racers with lighter vehicles, your setup may just be a bit too much for the slipper, in which case add an extra wave spring. You shouldn't run out of thread then.

I just tried to tighten my wave springs down some more and I just broke them. My truck will most likely be even heavier than your truck so I might be in the same boat. I am interested to see if you will need extra wave springs. What holds the wave springs together? Are they glued, soldered, or welded? Both spring came apart at the overlap sections. everything else seems to be OK. I have more springs on the way, but if I can fix the ones I have I would like to.

The springs are simply overlapped - not welded, glued or otherwise at the overlap section. You didn't break them at all - they came that way. :)

Thanks, Mike. I just got home and took it apart. All is well.

So I would like to know if you tried the third wave spring and if so did it work?,or did you get it worked out some other way?

To be honest I haven't tried it myself, haven't felt I need to. Though I do have a spare set of springs so I can try it, just won't be able to drive it until parts get delivered

I got the third spring on last night and with the third spring and it tightened all the way down it works! The front end comes off the ground a little tiny bit on launch but no more flips or wheelies and my drive train should be safe now. So I guess with 3 springs it will work good on a huge truck like the muggy. Im happy with it now. Im running a 15t pinion, 4 cell A123 batteries and a 40 x 82 mm 2000kv 4 pole leopard motor. It moves pretty good! I will try to get some video posted when it stops raining.

What diff fluid are you using in the slipper?, and do you know how much you truck weigh's?

[jamesban]

I was using 50k but last time I rebuilt it I had no fluid left so i just used diff grease. I have no idea how much my muggy weighs. Im guessing around 13lbs.

Pity I didn't spot this thread sooner as I had the same issue with the slipperential in a Savage and solved it the same way

One thing note is to make sure the overlap points in the 3 wave springs are evenly spaced out when you put them on. This seemed to be part of the issue with just two as when they were really tightened down it seemed to create uneven pressure on the slipper.

I could actually use 4 springs on mine if i wanted more adjustment area cause I got the springs flattened now. But im good with it where it is
