Hey gang, I had to replace the clutch spring in my Volcano and I want to make sure that I get the gear mesh right the first time. I have heard about the paper trick, but I'm not sure exactly how to do it. Can somebody clarify this for me? Sorry if this has been discussed before but I didn't feel like searching the whole forum. Thanks

rip a piece of looseleaf or printer paper and put it thru the clutch bell and spur gear then tighten it up, you should be able to pull the looseleaf thru easily without ripping it.

ever time i do the paper trick the gears are to close together and it will hardly row so i do it by eye and i havent had a stripped gear yet after 6 tanks but man the 18t clutchbell helps it alot it is pretty fast just for a 1 speed

You have to make sure you engine is square also. After you mesh your gears that is. Zach that is probably what is going on when you do the paper mesh, your not completely square.

yea i make sure the engine is square

I was just wondering because I noticed when I did the paper mesh it did roll very well either. Then I made sure the engine was square and it was perfect. I had to do very tiny adjustmensts to get it right took way to long. I just eye ball it also and feel for the right movement.

yep thats what i do to and i have about 8 tanks in my volcano stx and i dont have any stripped gears yet (knock on wood lol)

Thats sweet , wait until you get your XP hopefully you have the same luck. I went about a gallon without strippin gears. Then change clutch bell because the first one was shot. STRIP GEARS LIKE A MOTHER. sorry for shoutin had to get that out.

lol well soon as i get it im not even giving it a chance to strip gears i am gonna order poppers set up from towerhobbies

Thanks ehroof, I'll try this when my new HPI clutch bells arrive.

i just push the gears together and then slowly spin the clutch bell with one finger to feel if theres any resistance, then hold still the other gear the bell is connected to and feel how much movement there is between the teeth, and this has worked perfect for me using the 2-speed on my tyranno. Of course you'll probably need to feel it first when its fitted properly to get an idea of what it shud feel like.
The teeth are all still close to perfect after about 1.5L of fuel.

I do the same, I have gotten six gallons of fuel off of two clutch bells. You need to be careful at launch and when you land make sure your off the gas.

I agree Harry, see it all the time. ALot of people keep the gas on when they hit the ground...
