I used epoxy but it wouldn`t stick unless i sanded the shoe and the teflon but its stuck well now

poo i think you have been too cautious with the weights in the clutch if you have a hardened steel 4mm hex wrench cut four 8mm bits from it and stick them in along with the 1mm thick teflon and you will be hitting third every time and real early too

i sanded all the edges of the teflon once it had stuck to the shoes to reduce the risk of it peeling off

my mip temp guage normally reads 220-255 degrees
i use to be running my truck at higher temps before i done the third gear mod trying to get enough revs to change into third

i really will get a video posted this weekend

I only have 2 4mm allen keys, a long and a short, so I'm waiting till I strip one out and I'll use that next time if I need to. I also think it's best to try as many different ways to leave options open for everyone else. I'm hitting up the hardware store today, while I'm there I'm going to look into other ideas if I have time/remember. I just hope they have teflon there so I don't have to order some.

You could also use a 4mm hardened bolt in the same manor if your hardware store has them

I would really recommend a hardened piece of metal as it seems to have the right weight to it and mild steel/ stainless steel is too light

to do a proper job on it

the 1mm teflon is available on ebay real cheap if the hardware store don`t have any

i`d like to hear the other ideas you had in mind when you get back

good luck in finding what you need

just received the nemesis body i ordered it looks great on the truck

I'm looking to make a center skid plate along with a wheelie bar. I'll have to see what else gives me a idea there.

Do you have the center diff lock fitted ?

I had it in mine locked for about six months but got tired of the truck flipping over every time i would give it some gas

until i made a wheelie bar and then i really enjoyed its wheelies

i have removed the center diff lock at the moment, just removed it so i could actually climb over things,
and am running 500k silicone oil in the front, rear and center diffs

500k all around, wow.

I'm still slowly in the middle of doing my diffs, clutch mod, cleaning, now this skid plate and wheelie bar. I'm going with 120k center, 50k front and rear. If I get some 40k or 60k before I'm done I'm going to swap the diff's around for what I want to do. Heavy in the front for mud and climbing or flip them for dry flat racing and bashing. I'm hopeing the 120k will still put the wheels in the air but let me be heavy on the gas.

I still haven't found any teflon around here. I'm going to make a few calls tomorrow and see where that gets me. Most likly getting if from online though. I can't get this skid plate out of my mind so I might get to that sooner if I can find the right tools.

filled each diff right up but after a few tanks of run time it all frees up

so its not as hard as you would think to get diff movement still have the front wheels pulling when i nail it

it`ll wheelie a bit on grass and any thing grippy but i`ve done all the diffs on my trucks this way even put a little into the mg16

gona get this vid posted tomorrow of some real third gear changes, clear as day when the truck hits third it dips its ass and takes off!!!

Not really up to speed on inch to milimeter conversion,but if its about 1mm thick should be good togo

went to the link i got it from but they dont have it anymore, but heres some info of what i purchased

1mm x 300mm x 100 mm PTFE Sheet
Excellent chemical resistance
Excellent non stick properties.
Extremely low frictional properties.
Wide temperature range for a plastic (-260 to 260 deg C)
Excellent electrical insulation

If your stuck PM me and ill stick some in the post at least that way you know you`ve got the right stuff
it was real cheap so don`t worry about it costing you anything

the part about the none stick is the reason you have to give it a real good sand papering but it will stick once this is done

just want you to get the mod done as i have and to get it running good

I'm going to cut up more stuff to see what wieghts I can get to stuff in the shoes.

I'm lucky that teflon stuff I got is the same, all I saw was .040 x 24" x 8" for under $8 so I jumped on it

Just got the video uploaded to rcu videos

http://www.rcuvideos.com/item/X736D9NVZPNBLWRZ

i had the third gear set at 7.5 turns out but tightened it up to 6 turns out as it was comming in a little early,

think i`ll` losen it to 6.5 turns out that should be sweet,

but at least the video gives you an idea of how the truck should sound if your getting all 3 gears to work

as you can clearly hear second and third comming in each time without having to blow up your engine

to get the 3rd gear working

hope this helps all the people who are not sure their getting third gear

oh, man i really have lots of things to do my gst is not even shifting nada, zero,0 lol i have to buy some supplies and make this mod thanks, sparky and poo
but on the other hand, dogman if you said that gst's are rarely heard shifting into second but they clearly shift into third how come sparkies video i hear both shifts? can it be that its shifting into second but not third and you think that its third and yes i know that the second shifted early on that video. Also does any body know the default settings for the 2 speed shifting point? im planning on stoping spending more time with my other trucks and familiarising my self more with my gst.

just my .02 arc

PS have you guys tryed grubscrews?? 5mm by 8mm or less i have some im going to check with those but first i have to order my teflon sheet.
