So I just got my Jato (used) it came with a worn spur gear that I decided to replace. When I went to buy replacements they are all like 55t, 56t, or 58t. So I got all three thinking it would be fun to expierment with gearing. I come to find the one on my Jato (bad one) is a 40t and has bigger, deeper teeth so this new one does not lash up right with the existing pinion gear. Does anyone know what setup this is? Is this an upgrades gear set?

The clutch bell and spur that are on your jato are made for the traxxas revo. Since the revo uses a different pitch you cannot mix the revo clutch bell with the jato spurs. If you want to use the 53-58 jato spurs you must get the jato bell's. I have a set of revo 20cb 40spur I use on my jato for top speed road blasting, since that set up is usually only good for top speed road driving, I would recommend getting some clutch bells from 20-24 made for the jato for your spurs you just got. With smaller tires you can go with the stock set up 24cb 54 spur. For larger offroad tires you can go down a few teeth in the cb to compensate for the larger tire diameter.

A larger spur (58) will help with larger tires as well, but the cb usually makes a bigger difference when droping teeth on it.

Thanks-exactly what i needed to know, Is the revo setup stronger? It seems like the teeth are much beefer that the Jato's

Mspeed

yes the pitch makes it stronger, however you will be stuck with top end gearing only. The largest spur for the revo is a 40 and nothing really fits smaller than a 18 or 19 cb in the revo stuff. If you do the math your ratio is pretty high with no room to lower it for bigger tires. Keep the revo stuff for smaller tires or more powerful motors. I have a moded 3.3 basher that I put on some 2.2's and revo gearing and blast it in huge dirt fields, its pretty impressive if your motors up to pushing the revo gearing.

the gearing is revo gearing to make your car go faster.

Gearing is one thing that I really enjoy about the jato. The jato can use revo gearing due to the same three hole set up on the spur, and shares the same cb's as the T-maxx. I have found everything from a 14-24 cb jato pitch and 53-58 spurs. Most run the 18 cb and up to 24 cb for the jato. Also, for top end gearing 20 cb 36-40 spur revo pitch. The 2 speed helps alot when over gearing for top, you lose very little if any lowend.

get the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPWF4&P=7]robinson racing 20t cb[/link] because it is the only 20t cb with the right pich to run the revo 40t and 38t and 36t spur.

Mspeed

Not sure if your advicing me to get the 20 cb or everyone?[sm=75_75.gif]

i find nothing wrong with stock jato pitch, im running 24 tooth clutch bell with 54 tooth spur gear, pulls wheelies when ever it wants, i am running a Big block mach 427 though

Either way, what ever u decide you can run it lol, either get a revo spur gear or a jato clutch bell, or get both, then u can experiment with both types of gearing, its always good to have gearing options

nitrofan12

dude how did you manage to get a mach 427 big block in a jato 3.3[X(]?????.and what he said above^^^^is what i'd do if i were you.

scottywilkes

easily, extended chassis, big block engine mount and walla, only downside is 6 minute runtimes HAHA

Mspeed

Just to let you know, I already have revo 19, 20cb's 38, 40 spur's and 20,22,24 jato cb's and 53,54 jato spurs. By the way robinsion racing is not the only one who makes the 20cb for the revo.

klingtacular01

un true! You could have a 15 tooth clutch bell and a 38 tooth spur gear and that ratio is lower then the stock jato ratio. Stock jato is (9:4) 15 to 38 is (7.6:3) which you can do with the revo clutch bell and spur. But thats about the lowest gear ratio ive been able to find other then a 15 clutch bell and 40 from a revo which is (8:3) ***all my ratios are how many times the clutch bell must spin to how many times the spur gear spins***
