Gears to buy?

[lee2009]

Hi I'm having trouble figuring out what gears to buy for top speed.

Because Ive upgraded my engine to a 29cc and now it just reves its nuts off and hardly goes anywhere cos Ive got a 48t and a 16t

But before that i had a 46t and 19t but they are nackerd.,

so if i buy a 44t that's 2t less so does that mean i gotta buy a gear with an extra 2t so a 21t pinion gear?

But i can only find a 20t I'm confused.

but if i work it out from my 48t and 16t its works right.

Sooo if i get a 44t and a 16t will it work?

you'd want a 20/44 , for Fg's the gear set will add up too 64 tooth combined .

get a 2 speed and have the best of both worlds, worth every penny

 

[lee2009]

ok cool, cheers for that. well how much is a 2 speed, and where is the best (cheapest) place to buy fg parts from. thanks

Edit: oh and i live in the UK so UK shops would be nice.

keep your eyes on this one, h34r:

Why do both the gears look the same size on that?

 

[mooman007uk]

they're only 2 teeth difference, probably a 44 and a 42, i think that's what they come with standard for off road and 42 40 for on road, i'm running 48 44 on my baja at the moment.

 

[lee2009]

If i get a 44 and a 20 will i need to buy a smaller gear carrier, i ahve an alloy one now but not sure on the size ill check when i get some time, or are the alloy ones a standard size, thanks

 

[mooman007uk]

your carrier will be fine, there is a smaller one but it's for the 38t gear for the onroad guys with the small touring car tires
And the off road set is 46 44 not 44 42 as i said in earlier post, the onroad set is 42 40

 

[lee2009]

Hi again, do you think these gears will be any good

http://cgi.ebay.co.uk/ws/eBayISAPI....Track=true&ssPageName=VIP:Watchlink:middle:uk

or do you think i will loose too much low end.
my engine is a cy 26cc. but i just fitted a 29cc bigbore kit not long ago. and i also have a samba race pipe installed aswell. plz let me know

 

[mooman007uk]

what are you running for tires, monster, stadium, baja, on road? 42 22 gears will kill your low end unless you got a semi racing truck with the slicks or a road car, it's too tall for 2nd on my baja for off road so for single speed off road it's crap even with the 14t layshaft pinion. I got every 2 speed combo from 48 to 40 with pinions odd and even, for monster i'd run 48 16 with layshaft 14 or 16 if it's revving too much or a 46 18 with 16 layshaft...you can get FG odd size pinions that mesh correctly for in between for fine tuning. honestly get a 2 speed it'll give you all the options.

 

[lee2009]

Ok thanks, im using the normal marder wheels.
Well finding a 2 speed to buy is the hard part. nevermind a cheap one. :dots:

 

[mooman007uk]

with the marder wheels and your motor you may want 44 20..i'd use a plastic spur to test it first before spending out on a steel one just to make sure it's the right gearing.
yeah your right 2speed can be pricey

 

[cyclops1970]

with the 29 cc you should have enough low end outta the motor too pull threw the bottom end running the marder tires and a 20/44 combo without any issues .. you should pull some good speeds

 

[lee2009]

Ok thanks alot. ill just get plastic ones first.

does anybody know where i can get a exploded diagram from.?>

becasue there is a part at the front of the marder that i need.

its the metal part that holds the servo saver part. i cant explain it very well.

Are you talking Marder?

If your talking 6024 and can't find it the DTX one works too.

[lee2009]

Yea. thats it! lol nice 1, do you know what screw fits the top end of that part?

 

[Bigger the Better]

Yea. thats it! lol nice 1, do you know what screw fits the top end of that part?

Yup,

They are 4mm.
See screw here
The 30mm I think is slightly longer but I cut them to size. I think. I'll double check right now.

EDIT: Yup, 4mm but the Firehammer has a small plastic riser that makes the bolt need to be 30mm. So the Fg is shorter but you can grind it down to fit. Thats what I do.

 

[lee2009]

Here is why i need to get some new gears. becasue as you can see its all noise and wheelspin. and not action hahaha. too slow.
i think the 29cc engine should be ok with 44t. i hope.
