Alright, I am tearing it all down to strech it out. What do you guys use to lock these diffs? I wish HPI made a spool

cotharyus · 04-07-2007, 07:42 PM

I used JB weld on mine. Worked well. Now if I only had a front diff...

hdcustomizer · 04-08-2007, 11:00 PM

i'm pretty sure you can add a third gear into the diff case to lock it up if you wanna be able to unlock the diff for any reson latter.

swhenrik · 04-09-2007, 05:13 PM

I don't think the "relocated 3rd gear" method will work with the WK. There are only 2 spiders, not 3 like the Tamiya. And the spiders are smaller then the side gears, so the space between gears isn't "just right" for cramming another gear in there.

cotharyus · 04-09-2007, 06:28 PM

I looked at a couple of options before I went with JB weld, including some presure tensive fluids. The problem is, these diffs aren't sealed, so anything that remains even slightly fluid stands a chance of escaping out into the axle and causing problems.

Would silly putty work?

If you want a locked diff, No.

It works like a limited slip, and that is in a TLT style with closer spaced gears. In a WK it would work even worse.

Just use the right stuff, JB or hot glue. I prefer hot glue.

.... and with hot glue, it is fairly easy to remove IF you ever want to undo it (like anyone would.)

4x4dodge · 04-09-2007, 09:44 PM

Oh well, it was just a thought

Ill probably hot glue mine then

Project Dad · 04-09-2007, 09:50 PM

Well I ended up getting some silicone and filling up around the gears. It took longer for it to dry since it was not open to the air. I use silicone so I could remove it if I ever wanted to. Plus after it dries it is like rubber so It will give alittle.

lowblueranger · 04-09-2007, 09:51 PM

I just got my 4x4 today, and just hot glued the rear diff. I am waiting until the weekend to get all the stuff together for the stretch. I ran it stock and it seems like it will do fine after I lock it up and add some new tires.

lonewolf039 · 04-10-2007, 08:31 PM

I tried the silicone in my rear diff when I first got my WK, and it broke down after a while. I ended up cleaning it all off and JB welding it.

Thanks for the heads up. Prolly just redo them during tuber build.

Curious.....has anyone ever unlocked a diff at a later date?

Yes. Pressure tensive fluids can be drained, but again, you have to be able to seal the diff to use them. They are liquid and run out when static, but the minute you try to compress it or move something through it fast, they become essentially solid. I'm certain everyone can see the potential advantages of using a fluid like this in a diff. Dump it out, wash it off, grease it up, it's unlocked.

roktoy · 04-12-2007, 12:37 PM

Why did you decide you wanted it unlocked?

Converting an electric street rig from dragster back to "streetrod". Not sure why you'd want to unlock the diff on a crawler

I like pie · 04-13-2007, 01:35 PM
