Hey everyone,

I just wanted to know what clutch bell you guys would recommend for me. Its for a savage x 4.6. I'm running the 3 speed tranny w/ the high speed third gear and i'm running 18/47 right now.

I called HPI because it seemed like the savage was running on one gear. They recommended lowering the gears, they also said i can try retuning the tranny. They said to tighten the screw all the way for the 1-2 gear, then loosen it 4 1/2 turns, they also recommend that same setup for 2-3 gear. But they said most likely i have to go lower on the gear.???

I want to try avoiding changing the spur gear, so what CB would you guys recommend would work best. Also, should i get one of the regular vented CB from HPI or is there another brand/type that works better?

Thank for the help.
 
that truck comes stock 47/17 18 should not be a big issue if its tuned right. It does increase clutch wear but its a expendable part in the first place and 17-18 is not a huge jump in ratio.

Id focus on getting the tune good and fast then letting it get a lil higher rpm in the 2-3 shift so it shifts while the mill is makeing the most power.

Are you still seeing wheelies? I have never seen the F 4.6 run is person. I have had both K 4.6's and a slew of other mills. So I can only base my knowlage off them just FYI. but 47/18 sounds fine to me. My lrp and novarossi 528 both run 47/19 no issues.

But again only mess with the tuning of the tranny after the motor has a good tune. Also take note the tranny will shift different on different surfaces! If you tune it on pavement it will jump gears on loose stuff. Try to tune it in the conditions you run it in.

don't forget to have fun.... good luck!
 
I don't really see wheelies anymore after i changed to 18/47. So i guess i'll try the tuning method first, can't hurt. Then if i still don't see a change, i'll try a 15 or 16 CB.
 
that is a F4.6 right? How old is it and how is its pinch. there should be no need to go under 47/17...

jk, I'm in the same boat as you....just put the 3 speed on my 4.6 & it doesn't seem to really hit 2nd gear. was gonna adjust but busted an a arm after only 1 tank.
.
another dude at the bash had a new XL & it sounded horrible & wasn't shifting right. Judicator (from this site) adjusted his second gear 3 1/4 turns from flush & WHAMMO!!!!!!!. Although after running, the guy wanted 3 turns to get a faster shift to 2nd gear.
.
The XL runs a 16t racing cb. my x f4.6 runs a 17/47, but before i change my cb, i'm gonna adjust the 2nd gear shift point. after seeing his xl before & aft, imo 4 or 4-1/2 turns is way too much, but we'll see
 
Freddy the XL is geared 53/16 or some absurd # to make up for the lack of top end power that mill has. You cant copy his... It wont run on yours. The 5.9 does not run anything like a .28, my reason for selling it..

i thought the XL was geared low because of the hug tall tires........... when you figure out the actual final drive on 7" terrapins the XL Is actually geared rather tall.....

jk, bank is gonna tweak up my tranny on sat (which is same as yours) & then we will hit this post back with some good info for you bro:drunk:
 
Well, i finally put everything back on my savage and ran it with the recommended tuning. Unfortunately no luck. The car definitely seems to have more power, but i cannot hear it shift at all. I should clearly hear the shifting right?
Right now it, even though it sounds more powerfull, it sound like it is running on 1 gear.

I'm going to purchase a 16t racing clutch bell. This is what the HPI guy recommended. He said 15t might be to much, 16t should be just enough.

So my current setup was 18/47
I tightened the tuning screws on the gears all the way, then loosened them
4 1/2 turns (both for 1-2 gear and 2-3 gear) These were the settings recommended from HPI

My new setup will be 16/47 cb and spur

I'll post an update as soon as i can.
 
I am sure HPI mentioned it, but make sure your slipper is tight first and foremost. A slipping slipper will shift into top gear immediately when hitting WOT.

You mentioned no wheelies, so I thought I'd bring it up.

Hope you get it figured out.

If it's stuck in first gear with 18/47 moving to 16/47 will only make it worse (move the shift point farther away). You will have to back out first more to get it to shift (relieve tension on the arm). Then it may jump from first to third so you would then have to turn in second gear untill it starts grabbing, then adjust that for upper rpm. Then it will grab first, second, third, and your gone. You should be able to hear every shift.
 
What is a slipper and where is it located on the car?


Purenitro, when you say move the shift point farther away, do you mean loosen the screw to where it is coming out? or should i tighten the screw?

What do you mean by "You will have to back out first more to get it to shift (relieve tension on the arm). "

How will i know it's shifting from first to third, how will i be able to tell it is not second?

Thanks for the advice guys!
 
If it won't leave first, you will have to back the adjustment screw out (a little at a time). This will let it shift to the next gear, if it is too tight, the little arm that swings out and grabs the next gear has too much tension on it and it will not move.

After you get it shifting out of first then you can work on second. When shifting, if the engine winds out in first, then bogs in the next gear it is going into third. Tighten the second gear until it starts to grab second and adjust from there.

If the engine goes good from first to second but won't grab third, you then have to back the second gear screw "out" so it doesn't hold second for so long.

Work on getting it to shift out of first and let us know what it's doing. From there we can help you get the other shift point set.

It's your spur gear. Tighten the nut and spring all the way down for testing purposes. Then you can back it out about 1/8 - 1/4 turn once you know its not the issue.

Haveing a tight spur gear will help with the settings but it has nothing to do with the tranny. The tranny works with rotational speed, the lower the gearing the slower the tranny will spin, the higher the gearing, the faster it will spin. The adjustment is set when the arm will overcome the spring tension and let the arm "fling" out from rotational force and grab the next gear. If you plan on running only one gear ratio, the three speed is a good choice but if you like to play with different gears, you will have to tune the tranny every time you change them. The gearing changes the rotational speed of the tranny, if you gear up it will grab gears too fast, if you gear down it will get stuck in first as the rotation isn't fast enough to let the arm "fling" out to grab second or third.
 
So i thought i'd attach some pics to help out.

Is there a right or wrong way to put the gears? Is there a backwards way of putting them?

They are not good quality pictures, but if you guys can tell me the right way the gears are supposed to be installed, at least that will eliminate one possible problem.

Thanks
 
Ok well i retuned the tranny again and i also tightened the nut and spring on the spur gear.

The tranny i did a little over 5 turns out (from the completely tightened position) on 1-2 gear and the same on 2-3 gear. Again, the car sounds a lot more powerfull, but you can clearly tell it is not shifting.

Ok, Bank tore down my tranny & found the the reason it wasn't shifting 1st to second was due to the slipper nut being loose. We tightened it & now , running a 17/47, it rips from 1st to 2nd but i need to adjust for a shift into 3rd because it doesnt right now. i am going to adjust it a bit to get a quicker shift into second, but it totally rips in it factory-set position.
