It came to my attention that there is a possibility that the front and rear diffs in the RTR versions of the Hyper 7 (RTR, PBS and PCR RTR) may not have lube in from the factory. This was noticed after I opened up a few diffs on peoples new rides. This only seems to be affecting the Standard diffs and not the Spiders, If you have one of the said buggies then I strongly recommend opening up the diff to check. This will also cause a loud squealing noise when in motion and premature failure of the unit.

Just looking after your pockets.

yeah man, i opened mine up and there was a tiny bit of grease in there.... good thing i opened them to clean and add new silicone weights, or i'd be really unhappy....

hi when you said jst looking after your pockets what damage could have been done.
Thanks

You could've had to replace all the diff internals. At your own expense. You would not be covered by any waranty for this as you are told to inspect the buggy before running in in the instructions.

Yep, I opened mine up to fix another problem and noticed there was very little lube in there. I ran accross this tread while looking for info on what lube to use for the diffs.

Can some people post what they use especially for all around conditions....mostly bashing!! I have looked on Towers web site at what they had and damn there is a lot of choices. []

what kind of oil do i use. My inferno is making the afformentioned squeling noise. Can i use shock oil?????

or do i use silicon based grease?

OK i use silicone diff lube! i have a bit of a strange set up but works well for me

10,000 in Rear Diff

5000 in my Center Spider Diff

7000 IN the front diff

35 wight for shock oil all the way round

Blue medium springs

Hope this helps!

depends on the track you run on ? if its a long sweeping track then you want to have a tight rear end , use 7 to 10 k silicone or of its a tight track then use 1 k silicone. one problem though , they will leak very easily and you will continually be filling them up. i use Prepsol light grease and a squirt of singer oil. not too much either and it works great in the rear. i use the same in the front but i have my front diff locked because i run on a tight flat track, and in those situations you need front end pull.

i run 5k up fron, 7k in the middle, and 1k in the rear. It is on rails down the straights...... and i can slide the rear end out if i want to around the tighter corners. it really grips.... and transfers the engines full potential to the ground. I was amazed at the difference between the stock grease, and the ofna diff fluids.

I havent recieved my new Hyper 7 PBS Yet so i dunno how involved this process is. However is it a pain to open up these diffs to put the lube in them? Im used to working on T-Maxxes and I know the buggies will be more complicated and tight but I hope its not too bad. Thanks.

Ben you have a center Spider diff (unless you bought and fitted one today). The give away is the word SPIDER written on it. And you only run grease in a Torsen, or 1000 wt max.

Anyone else wondering A good starting setup I find is 3000wt Front, 5000wt Center and 10,000wt rear. These are all Silicone Diff Lock Oils. And yes you could run shock oil in there but it is so thin that the car would handle like crap and the diffs would need rebuilding every session.

Graham i dont know what u are talkin about i said that

Ben... how does it handle with that 10k in the rear? Just curious always trying new stuff

just put a 053 pipe on it aswell but havent had a chnace to run it cause of the storm this weekend here in spain, i will let you know mid week if the waether clears up

wait a minute, why would you want heavy oil in a diff for a tight track??? you wouldnt get any diff action. now if the track is really slick then i could see where this wouldnt be a bad idea.

What the deal there Alex man, you say 10k rear, Ive never heard anyone recomend any higher than 1k, even when you check out the pro's set up sheets from some of the nationals (on CML's web site) you rarely see above 1k in the rear............. 10k would induce silly wheel spins on the rear tyres during turns making turning less predictable would it not?
