Ok I got the rear shock off and after struggling with the lower mounting screw, I finally found out that it is reverse threaded!!! I am just wondering why they didnt note that in the instructions or not made it more clear (i will look at the instructions more closely in the am.) also why not drill all the optional mounting points? I only as these questions as I am still very new to R/C. as this is my 2nd car. is this normal? the shocks being..... is it broke? i dont know. I will take this one to a LHS and see what they say about it but I guess now that its off I will just rebuild them all if possible.

VNMSGT...... I know youre out there bro, so help me out, what should I be running keeping the local track in mind (Clermont) as far as shock oil F/R. and I am thinking that F/7 C/10 R/3 is pretty much standard? or at least a good starting point for the diff oils?

Please give me a hand - Ive got a half built diff!!

Just put the washer up to the side of the pic on the manual and see if it is the same exact size. All mine were and I had no misprints. Take some pics and post them would be better for us to help you.


Its definately the same washer, I put it on top of the diagram on the left and it was the same size.

I will take some pics tomorrow night (out for a few a Christmas drinks tonight).

Cheers vnmsgt!

Rican - The 7/10/3 combination has been recommended to me as a good starting point. Its what im going with.

jaywax,

Those are some great videos! Was that a friend of yours doing the videographer work? Whoever it was, they did a super job! One of the best I've ever viewed - great stuff!

There from a guy named Griz. He films in the Austin/San Antonio area. If you go to the member video section, you can see some more of his vids.

When filling the diffs with oil, how full should they be filled?


never to the top, heat inside expands the oil and causes massive failure. fill them just enough to cover the crosspins, about 1/2 way. anymore and you will have cronic leaks. trust me .

quote:

I filled mine basically nearly to the top, so that they would still fit together without having oil goup out all over the place


please let some out or there will be posts of diff problems with the st, i'm about 30 days away from ordering now.

anybody seen or thought of a pbs conversion on the st pro?

Ran my hyper tonight and I love this thing. Have not ran it too much because I had a fuel leak problem which was in my carb and then my steering servo fried and I put in a different one with a shorter servo arm and had steering problems till I put the longer arm on, but now it is good.

One think I have noticed is on short tracks with tight turns the truck likes to push out of the turn pretty good. I was told because it is from the center spider diff that the spider diff was meant for europe and not the US and is better running on grass and stuff and not the clay we run on, and that the hypers with the regular center diff were sent to europe by mistake and the spiders diffs sent here. Is that true?

Also would a regular center diff stop this pushing problem? Like I said only on short tight tracks, On larger tracks it is fine. I was told the spider diff tends to want to lock up the front and rear tires like a full time 4wd and not let them work more independently like a regular center diff.

VNMSGT - Here's some photos

The first one shows the manual with the washer.
Second one shows the end of the diff with the washer next to the bearing (where it should be)
Final one shows that the washer is big enough to slide over the diff cup - Surely this cant be right?

Yes that is correct. When you put the diff in the diff case the washer will be in between or sandwhiched by the diff case and the bearing. This is what shims it inside the case to the gear that the center driveshaft connects too. When the diff is removed the washer will fall off of the cup.

I'm pretty sure I left those rings out and shimmed it some other way - maybe one extra one inside the diff... Don't really remeber - but I didn't put those gold rings in.. At least there are two left in my little box of screws....

Well they do give extra's depending on how much you want to shim it. Some left over should be ok. I did it like the manual for now and it is ok.
