HPI Super 5 SC gearbox.

Is the same gearbox as in the Flux and Nitro savages.
Only difference is the inside gears.

This is a quote from the savage-central topic i found it in..

Finally got the rest of my parts in and found time to assemble the transmission. There were no big surprises along the way, just buy all the parts and follow the instructions.

I started with a stock flux tranny (with cups, no slipper) from ebay. I also previously purchased the lightweight hardened gears to build the bullet proof flux HP tranny. It looks to me that the 5SC tranny is the same type of hardened lightweight gears. Great, bulletproof and a center diff!

I covered building the diff in a previous post, this will pick up from there. Basically what I did was use the exploded view from Hpi's website and order all the part numbers. this was overkill but I like to add stock to my spare parts stash. One example is the pins, all the gears come with extra pins so the pack of pins I bought was not needed, not to mention the original pins from the tranny can be used. Same thing with the o rings, my diff kit came with all hardware so extra o rings were not needed. You can decide how much to buy, I will try and accurately detail the parts I used.

Diff parts list:
HPI 106273 Racing Idler Gear 30Tx1M 29.99 (38.98 shipped)
HPI 106277 Diff Shaft Set 5.99
HPI 87193 4 Bevel Gear Diff Conv Set 11.39
HPI 86827 Alloy Diff Case Savage X SS 11.39

Transmission parts list:
HPI 86972 Washer 6x15x0.2mm 3.69
HPI Z877 Washer 8x10x0.2mm 4.59
HPI Z689 Shim 6x8x0.2mm 2.79
HPI Z245 E Clip 5mm 2.79
HPI 107496 Bearing Mount Spacer Set 5.29
HPI 106269 Drive Gear 21Tx1M 15.79
HPI 106275 Idler Gear 41Tx1M 26.99
HPI 106271 Drive Gear 31Tx1M 30.10 (LHS)

Misc parts:
HPI B032 Ball Bearing10X16X5mm Savage 21
HPI B023 Ball Bearing 6X13mm

The bearings are miscellaneous because I used the Savage X SS alloy diff cup. That changes the the bearing from a B085 to B032 (which I had on hand). The Flux HP uses one B085 and B023 on the lower shaft which would transfer to the 5SC tranny but you will also need an additional B023 and B085. The 5SC doubles up on bearings on the diff.

Optional:
HPI 107460 Drive Shaft 6x80mm Super 5SC Flux 5.99

The 5SC drive shaft for the dual pad slipper is optional. I assembled my tranny with the stock flux shaft.

I added the prices so you can see what it cost me. Starting from scratch to assemble this entire transmission is a staggering 150.79 in parts + donor tranny 36.00 + shipping 23.59 = 210.38usd. If you have more patience you could probably shave it down a little. Those gears sure add up, ebay didn't have much to offer. I've had good experiences with RCHobbies4life and their prices are always pretty good, they just didn't have some of the gears in stock. The kicker is I don't have a truck to put this in. I just sent out half the parts of my build to be anodized. I imagine it'll be a few weeks until I can test anything. Oh well. at least the tranny is out of the way. Here are some pictures.

Sounds interesting, I'll have to do some reading on this. Make sure you to post when you get a chance to run it
 
I am sure it will work fine.
Only thing is that this way you only have rear brakes..
On a Flux the motor is used as the brake but on a nitro you have the mechanical brakes on the rear of the gearbox only.

It will take a while before i can run it. The LRP still has to be modded and run in using the Easy Break In System..
Hit a bump in my budget so it could be in a month or 2 . 🙁

Checked it out, ya it def will work. Just wondering how it will act? I guess more like All Wheel Drive opposed to 4 wheel drive? How's the single speed going to perform with the nitro? Will you loose a little speed off the bottom end, and a little off the top also? Sorry about all the questions, this is just the first I've heard about a center diff that can drop into an x tranny.
 
This will make it more truggy like i guess.
A lot of trial and error with gearing. I will start at 17/49 and it looks like i will end up around 20/43..
The engine i will be using has so much torque it can handle just about anything i throw at it.

And if i don't like the way it drives i will take it out and place my 2 speed.. 🙂

No problem. Just ask away, without questions to be answered we wouldn't learn anything m8..
There are also a lot of questions i didn't think of myself.. 🙂 🙂 🙂
 
Good to hear you're up and around. It's often humbling to realize how much we enjoy what we take for granted daily. I'm anxious to hear the center diff impressions. lmk if I can help with anything.
 
I did some maintenance to the Octane. Started it up. adjusted the idle. But seams to me i have a little brake pressure on when pull starting it.
 
Stripped, cleaned and rebuilt my 2 Savages, put a new gearbox in my sons Nitro Rush and built him another from a pile of spares I have:ercm:.

Looked at my Octane sitting on the shelf so put in some freshly charged batteries & fuel and it started right up, idled good and drove superbly. I'd almost forgotten how loud it is but I still think that it makes one of those noises that makes you smile so much you are in danger of the top of your head falling off :woot::woot:
 
spend more money, and trying to get a mirror finish shine on some of my alloy!
Hi pal ,you ever tried a product called crystal glo? I don't even know how or why I ended up with the stuff but I'm not looking forward to the day it runs out.
 
Sorry, not with my savage but with my Mugen MBX5T truggy.

Killed the front diff and my modded K4.6 is dead... First time out after 8 months.. 🙂 🙂 🙂 🙂
 
The lrp is going in my FLM extended savage. Savage has a Super 5sc center diff I wanted to try out. So hope my lrp modding is done soon. Can't wait, and now my truggy dead.. .... Aaaaaaaaaa...

That's why I have 2 as well. But as you're aware, that doesn't seem to be enough. I'm pretty new to the hobby though. Bought that 25 used maybe 4 months ago. Then when it wouldn't run, I bought a Cen Matrix Arena TR that's currently down as well. I could probably have them both up and running already if I just had a little more free time.
 
Time isn't the problem here. 😉 €€€€
I broke my shoulder blade and shattered my elbow in November. Finally able to work on the trucks and drive them. And now this happened. Second tank in so only got to drive 15 minutes or so.

Man that really is no good. I'll keep my lack of spare time lol.
 
Ah well. You know what they say. Sh*t happens..

Took the engine apart and there are 2 deep scratches in the cylinder.. 🙂 Time for a new one. Found a small piece of metal in it. Looks like it was from a glowplug.
 
When it rains it storms. I have been kind of sort of but not really hoping that happens to me so I can justify dropping the money for a new LRP myself.
 
Let's see, took my savage out for a run first time in like 2 years. Trying to get back into the hobby. Had a great first run only to blow the clutch out on the second run. Also using an old radio system so I just purchased a new radio system, Futaba 3pm-X. Got a lot of great reviews so well see. As far as the clutch going to install the integy upgrade clutch.
