Still Needing Help!

[KbigO69]

Ok I'm still needing help with my mt. I have replaced the clutch disk, clutch bell, even put washers in between the spring tensioner and the clutch and still it slips at full throttle. I've got it adjusted where i can almost punch it full throttle. but i can do a high speed run and while doing so if i push the throttle all the way i can hear the engine rev up but it just slows to a stop because of the clutch slipping. any ideas

I'm not too sure so hopefully someone will back me up but are you sure it is you clutch slipping? Maybe you spur gear and clutch bell aren't lined up quite right so at high speed it may slip. Also next time you have the clutch bell off rough up the clutch shoes and inside the clutch bell this will help the shoes grip inside the bell.

I would try to tighten up your slipper clutch on the tranny

I was thinking +1 on the slipper clutch right up until you said it will slow to a stop with engine at full RPM. That is definately NOT the slipper clutch prividing your description is accurate. I'm sitting here scratching my head trying give you a start point and am a little short on information.

IF, it hooks up and launches as in, motor is audibly loaded and increases speed as rig increases speed then just stops pulling and stops with motor still reving, look at main clutch, disassemble and check for signs of excessive heat.

IF, the motor pegs straight to top rev and stays there during rig acceleration, then you DO likely have a slipper clutch issue. Easy check, leave the body off, nail the throttle out a ways and nail it to bring it back to you. when it returns, reach down and put a finger on slipper clutch. If it burns the crap out of your finger, it's way too loose.

But that still doesn't explain the slowing to a halt with motor reving........
UNLESSSS your description of what it is doing is more a description of what it did ONCE. If that be the case, your slipper was way loose, you smoked and burnt off the pads and lost all contact with your slipper clutch.

check out the slipper clutch first, make sure you can barely turn spur gear while holding shaft still. If it turns free, there's your problem.

Re post when you at least got those two things looked over good.

Ok I will check it tomorrow but as for tightening the clutch I have it fully tightened and I cannot turn the spur gear at all witout wheels turning. What r the shoes in the clutchbell?when ictook it apart I noticed nothing really. Wld ya like pics?

 

[KbigO69]

how do i put photos on here? I'm thinking there is a big misunderstanding with what type of clutch i have so i want to put pics on here to clarify

two shoe clutch. you can tell by the number of pegs on the flywheel

 

[KbigO69]

flywheel? do you mean spur gear?. and what are shoes? lol

 

[BradZ]

Yeah i was about to say maybe the pads are worn, that will make it slip.
Take the CB off, then you wil se the shoes. Upgrade to alloy if you want them to bite hardcore!!

 

[cptvkirk]

what model rc is this. i think you are holding a form of slipper clutch but i'm not familiar with it.. I'll see if i can find parts sheet on it online to be certain.

if It is a slipper clutch, where did you say you were adding washers? It looks like some sort of fixed torque clutch that is set outside the rc and then installed as an assembly but I want to take a look at your manual to be certain.

 

[RC Addict]

It is a HPI Nitro MT. My suggestion a while back was the slipper pads on the back-side of the slipper. It still is my suggestion.

two shoe clutch. you can tell by the number of pegs on the flywheel

As I was going to say. This is not a slipper clutch, this is the flywheel that your clutch shoes link to. This isn't where your problem lies.

You have three pads on the back-side of your slipper clutch. That is the black gear that mounts on the transmission and spins via the clutch bell on the engine. You are looking in the wrong place.

Remove the slipper from the transmission by taking out the three screws holding it on. On the back-side of the slipper there SHOULD be three pads. They are either dirty or worn.

Let me know if I need to explain it further.

dude nice how many cody's are on here. thats my name too.
sorry just had to say that

 

[KbigO69]

ohhhhhhhhh ok i feel dumb now. i thought the shoes were on the clutch itself. duhh lol ok well if something breaks and i have to take it all apart again i will check it out but until then it runs pretty fast without fullthrottle. I'm tired of taking it apart i have done it every night for the past 2 weeks lol thanks for the helps guys i know I'm a hassle lol

 

[cptvkirk]

shouldn't have to take it apart other than drop the body to tighten up the slipper clutch a little...if you keep running loose, you'll either smoke through your slipper pads or gloss them over making adjusting it properly near impossible. well, they are probably glossed or burnt already...but snugging a bit will keep it from getting worse.

 

[KbigO69]

ok guys i have finally found the long lost clutch shoe and i have attached a link for the pic. now where do i go from here as for telling if its worn and stuff like that

 

[cptvkirk]

that is your main clutch, it should be clean and the edgeds of the shoe should be well above the spring. If that spring gets close to being flush with the edge of the shoe, it's time to replace it.

Keep in mind that picture is your main clutch, and from what I can see appears to be just fine. This isn't the slipperclutch that RC Addict was referring to.

I looked through your manuals for this rig, I could not find anything on the slipper clutch to be able to point you to visual reference. But, I couldn't find anything on the pieces you were holding in the previous posts. Sorry I couldn't help you more but I have to defer to someone with more knowledge of your ride.

 

[KbigO69]

well my main clutch def needs replacements cuz the rubber and spring are just about equal with each other. anyone wanna send links for one from towerhobbies? ))... hmm so where is the slipper going to be? i have the mt just about all apart except for the flywheel is it behind it?

 

[KbigO69]

anyone??

 

[cptvkirk]

i was talking this over with rcaddict and i'm afraid i'm at a bit of a loss for info for you. the slipper, as I am familiar with them, are typically part of the spur gear assembly. But, everything i have seen on your rig either does not show it, or i am not looking in the right place.

Could post a close up of your spur/clutch/tranny assembly. Maybe I can see it on the pic, maybe not. can't promise help but i'll try.

 

[KbigO69]

dern is it possible for one not to have them. the spur gear/ clutch assembly goes tension nut, tension spring, spur gear (which fits into clutch) first part of clutch, clutch disk, second part of clutch, and thats it lol. then on the engine it goes clutch bell, main clutch(which i need to change) then flywheel then engine
