Center gearbox case's? which is better

[ShiftPoint]

Hi,

I am putting together a savage X 4.6k kit, I have a couple different centergearbox's (plastic stock) I have one that is, well it only opens in half (it is from an assembeled 3-speed) the one that came with the kit opens in half but also looks like the top will come off. I need to install the 3-speed gearbox kit. and was wonderng,

Which one is better? which is newer? Does the removeable top make it easier for repairing it when the time comes?

guess what I am asking is which one should I use?

Thanks,

JohnI

The one that is modular is from an x ss truck and it is must with a 3 speed.

It looks a bit stronger in places to me, what's weird is the one that the top does't come off, it actually came from an assembeled 3-speed gearbox I bought. I guess maybe I got an old one or they were out of the modular ones when they were assembling them??


I am not to this point quite yet and haven't even read ahead in the instructions yet but I am kind of worried about adjusting the shift points, I hope there i a default or factory setting like the carb needles have. Iam a little worried about getting that set right.


Thanks,

John

Yes Wister,..
I believe the gears are already factory set for the correct tension.
You shouldn't need to mess with them. Just assembly the tranny and go.

Most shifting issues arise due to odd CB/Spur Combo's or an impropperly tuned engine. An engine needs to be aleast 90 % broke-in before propper shifting occures also.

Hi,

Iam having a bit of trouble with this kit, the step where you put the 3 gears on the driveshaft then a spacer, then an E-clip, I don't have a spacer that fits there?? It doesn't show one in the pic of the kit but there is one on the driveshaft that I removed and the spacer is there but it is too long? I really don't understand what they want us to do here.

Anybody know?

thanks,

John

Hi,

Here's an update on this spacer issue. I called HPI to see what was going on and make sure I wasn't doing something wrong, where the old spacer should fit.

Ok, I learned someting anyway, the pictures of the parts in the instructions books are made to exact size or actual size which will help in this case.

Also the first guy I spoke with didn't have a clue, I had to ask for someone else he was telling me I had to buy a 3-speed case and all kinds of stuff that just didn't jive. the next guy first said the spacer should be in the kit, but I informed him it wasn't in the picture

Ok, believe it or not HPI called me back, I had not left my number or expected a call so that is pretty good customer service, he called back to tell me where the spacer is, (at first he was telling me to grind down the old spacer) the spacer is molded with the big plastic gear, so you have to break it out of the center. That's pretty cool they called back.

Later,

John

yea.. I remember having that same issue come up when I installed my three speed...
I remember eventually figuring it out but didn't find the shorter part until after I grinded the old part to size...
That's cool that they followed up on your conserns, bud
The instructions are good in some ways yet leave abit to be desired in things like this sinario...
Keep wrench'in my friend...lol

Hi,

Do you guys put grease in the center gearbox? The instructions don't show any places to grease, and there wasn't any in the 2 speed I opened, however on the assembeled 3-speed I bought it didi have grease in it??

Just wondering, seems like it would be good to have some in there but I know in some cases it just collects dirt.

thanks,

John

Ive ran my three speed with out greese from the very begging. if your do add greese it will only bog down your gears. if you feel that a little lube might help in longjevity then use white lithium Sparingly. but you don't need it.

Just run it dry... if you put grease in there it will screw up your clutches. And the tranny wont shift

Thanks guys,

I wish I could remember where I got that first 3-speed, it seems like maybe someone (3rd party) maybe assembeled it, because of the grease and the old casing that isn't modular. It looked new and all and was in a box with unopened bags and stuff.

Just kind of threw me off, one with grease one without, then the case, which I got after the truck so I thought it was newer, just strange.

Thanks for the advice,

John

Ive noticed HPI is good about adding some extra parts in with there kits, even the RTR truck I got had lots of extra parts. I like that a lot!! (I hope there extra parts or Ive really been messing up!!

Wister my three speed which came pre assembled into my s25 ltd Ed also came grease and in the non modular case. I don't think the assembled three speed kit has been updated to the sav X casing. Otherwise all the ones I have seen are old which is also quite likely.

I figured it had to be something like that.

Hi,

Something I liked better (I will know for sure when I try it) on the RTR than what is on the SS is the brakes. On the RTR the disks are fiberglass or something like it (there red) on the SS the disk brakes are steel and I had to glue pads on the metal bars that t go arross. One thing for sure it is a lot easier putting the red disks on they fit loosly around the big nut (the nut is bigger on the red one too) these metal ones were tough to get on.

I have heard thry work great .. (red ones) .... also I have benn wanting a set .. did some ebay surfing and they are selling for like 26 bucks OUCH !!!

 

[X25]

i hear the secound run split case are great. added some bracing to them to hold the power of bigger mills. just what i have been told. i run both style cases and have not had any troubles out of either one.

Hi,

Yes the red one's work greak. If you get them you will need a different nut (the nut that they go around) it is bigger than the other one. Also the bushings that the metal rods/plates (the 3 that put pressure on the disk's) the spacing is futher apart, the spacing on the bushings is 10mm on the metal ones. Actually there is no bushings on my truck with the red disks, they have screws that are only threaded so far up then there is (I don't know exactly) about 12mm to 14mm of the screw that is smooth, that is there instead of the bushings.

I think that is all you will need to convert it, on my alloy truck, the alloy center gear box had the same problem-----I can measure the length needed for the bushings for the red disks I have a extra set of the screws in the old case.

Ok I measured it, the bushings or lenght needed (if you have screws that are only partly threaded) for those red disks and the brake plates (shoes i guess) is 12mm, the ones for the metal diss is 10mm so it doesn't seem like much, but believe me that 2mm makes a big difference if you need it.

These metal disk brakes seem like they are trouble waiting to happen, loks like they may bind up easy.

Has anyone used these metal disk duel brakes, if so have you had any problems? Do they work?


Does anone think it would be a good idea to remove the disks and take a file or dremmal and make the whole in the center a bit larger so it will slide easier on the nut? Any opnoins?

Thanks,


John

They actually redid the X case again adding 3 screws to the top instead of 2.
