    Is this normal?

    Today I was running my Jato 3.3. I put in the after run oil, and I had the truck on my jack stand. When I went to cycle the after run for 3 10 second cycles, the spur gear and the wheels were turning. I don't remember them doing this before. The slipper is 1 1/2 turns out from tight, and I did have to retune today due to the changes in weather, including leaning the lsn 1/16 turn. I did break a front camber link today. Hope I didn't to more damage. Thanks for your help.

    Uh Oh. Not sure I can tackle that one. It ran fine today. I had tightened the slipper after last weekend. It was set at 2 1/2 turns from tight. How will I know if it is bad? I'm new to this. Thanks!

    it is rely easy, the e-clip on the gear on the motor, carefully take it off and see if the spring is good, there sould be nothing lose at at all, next time you run it, pick up the back if the wheels keep spining then your idle is wrong or the cluch is bad

    Opening up the clutch is easy.

    Take your motor off the truck.
    Pop off the E-clip.
    Pull of the clutch bell.
    You will see your 2 clutch shoes then.
    Take the clutch shoes off the flywheel.

    It may be possible that your spring broke or maybe even one of the shoes.

    The spring should be snug around the 2 shoes.

    If this is a clutch related issue, check out the manual for the TRX 3.3. Starting on page 36, there is a section on rebuilding the engine. In there, you should find information about the removal (and installation) of the clutch. That should help you out!

    It is a PDF file:

    OK. Doesn't look too bad. I'll try it tomorrow. I have a great LHS handy if I run into problems. I hate to bother them everytime I have a problem. I'll try to take it apart and see what happens. Guess that's the only way to learn.
    Thanks!

    little tip: put a rag over the e-clip when you remove it so it doesn't go flying.

    WOW that's way more work than you need to do to get the clutchbell off... well atleast I think so. this is how I'd do it:

    Take off your dirt guard on the right (passanger) side of the truck.
    Take off the right side rear wheel
    Take the 3 screws out of the spur gear and remove it.
    Take off the E-clip and presto.... it should slide right off.

    no need to take your motor out. that can be a pain if you're still using the EZ start.

    Thanks for this suggestion. I really didn't want to take the motor off, as I am using EZ start. What causes the clutch to go bad? The previous owner flipped it when he ran it after break in and had the slipper really loose. I know I should have bought a new one. I have had it since April with no problem until now. Thanks!

    OK. I got the clutch assembly kit with the shoes and the spring. I have the slipper assembly off. How in the world do you remove the e clip? I can get a screw driver in there and pop if off, but getting it back on is going to be fun. Any suggestion? Thanks!

    do you have a set of small precision screw drivers for like watch/glasses repair?...if not you can pick a cheap set of them from your local dollar store...or perhaps a you could ruin a fork by prying on the e-clip w/one of its prong as a last resort...

    use needle nose plyers to grab it in the middle and pull it off. If you lose it or ruin it, it's a .19 cent part at any hardware store! I just lost mine this weekend off of the T-max.....lol I also baught, like five extra!

    Use needle nose pliers to put it back on also. They are very easy to put on, just make sure it is on completely. Use the tip of tone side of the pliers to grab the middle of the clip, the tip of the other to grab the shaft (or the hollow center of the shaft, and squeeze.
    Cheap, Fast, Reliable. Pick 2.

    Thanks everyone! My spring in the clutch was broken and the shoes were rubbing the clutch bell. I replaced them all and got it back together! It's been raining here in PA, so I haven't had a chance to try it yet, but I'll give it a try this weekend. Thanks so much for all your help. You guys rock!

    Good job. It's always a satisfying feeling getting a problem resolved yourself.
    No need to drop it at the LHS.

    The clutch isn't too bad. Except that nasty e-clip. Those things are evil.

    Yea, I am trying to learn as I go along. I hit a pole and broke the front camber link and fixed that as well. I really want this to be a hobby where I can tinker myself. I used to have a lifted Jeep Wrangler with a carburated V8 in it that I could tinker with, but that died and I bought a new one that is impossible to work on. I am a dentist, so I like to work with my hands, and RC is a great way for me to relax on the weekends.

    It can be done without pulling the engine
    If it doesn't break you're not driving it right.

    line it up in the grooves on the crankshaft, and use some needle nose pliers to snap it into place
    If it doesn't break you're not driving it right.
