TLT Axle Diff Lock

[TWINSET]

Ok, the easiest way is to get hold of the G parts from a XC or CC kit

Part number 9005422 ( £7.00 per axle from Time Tunnel)

The G frame contains bits to lock 1 axle.

The cheaper way

(but probably slightly less removable too[])

Get the diff ready

If used, clean off all grease or other lubrication

Start with the gear assembled into the bigger half with the conical  protruberance at the back

Get some 2 part metal paste; JB Weld, Quik Steel or this one, Hard & Fast by Evo-Stik

(I'd actually recommend this one the least, this pack was very hard to knead together, and the outer 'skin' was quite crumbly)

Put a good sized blob over the gear, and spread it right into the corners of the 'tub'

Another way is just roll the blob into a 'worm' and lay it into the 'tub'

Press the 'spider' gears firmly into the metal paste, and start packing around the gears so they can't move.

Be sure to keep the top teeth (highlighted) clean of paste, to allow the other large gear to sit properly.

Place the top gear on, and 'dry fit' the cover, just to make sure the diff isn't over packed

This is fine

Pack paste into all the remaining 'air spaces' inside the diff, just to ensure the assembly can't work loose over time

Once it's well packed screw the cover on.

Don't expect the screws to be able to compress any excess paste - you'll break one of the tabs off of the cover [:$]

Finally, poke a small allen key or similar long, thin thing thru the

centre hole, just to make sure there's no metal paste stuck up there

A super easy way is to pack the diff with silly putty. It locks the diff, and when your ready, it is easily removed, leaving no mess at all. For those of you not familiar with this, silly putty is a kids toy, silicone putty. It is stretchy, bouncy, and can pick up ink images from newsprint. It cost about a dollar for a little plastic egg full,, and thats enough to do 2 diffs.

You can use an extra small bevel gear (BM2) placed between two of the ones in the diff to lock it.  If you don't have any extras, you can just use one of the original 3 in the diff & put it between the other two (which is what I did).  This will lock it, seems to me to be the simplest way, & is reversable.

Biggus sent me some very handy packaging material which also works superbly!

Pack the diff fully, and you get a 1/4 wheel turn (as the material compresses) which gives better initial steering response (compared with a fully locked diff) but also provides the funtionality of a locked diff and is REALLY quick to reverse.  No damaged teeth or anything to unstick / de-gunk.

Seems the best way to do it as the diff worked perfectly when unlocked (worked as it did when new - no noise, sticking points etc).  If too much strain goes onto the diff, the material is likely to give way before the diff so also adds extra protection for your metal bits [].

LOL - again with this?

gettin' the original diff lock parts are so unbelievable much easier - keeps your rig original and reversable and less messy and so on and on and on... BTW, I picked up several spurs for only a couple of $ each a while back, probably still avaiable at the same cost if you know where to look...

well well, I have switched scale models anyways, working on my 1:1 Land Cruiser BJ42 now, not much different from working on Tamiyas, parts are only soooo much bigger I am about to lock the diffs on this baby now, maybe I will try silly putty or rubber string...nah

[jerrywasaracecardriver]

Going to need ALOT of silly putty for that big ole cruiser.

Before you lock them permanently on the 1:1 one transfer it off road, as you will never be able to drive on road again, 1:1 steering and tranny don't forgive different rotating speeds at turns like our little overdimensioned cars [][]

You could fill the diffs on the Toyota with rubber bands, you would get an LSD effect so you could still drive it on the road then []

[DJTheo]

Or better Tamiya AW grease, propably 500 little tubes per diff at $5 each LOL

Cheers

Theo my man, I was only kidding about lockin' the diffs - I am gonna install ARBs hydraulic difflocks on this baby... It's not a crawler and I use this as a daily driver. It kicks *** off road like it stands now, but locks are essential.
