My clutch isn't engaging. Need some advice.

[chvyhs]

I bought a clutch and torque converter assembly on ebay. I think the springs on the clutch are too strong. I don't think the centrifugal force being generated by my GX270 is enough to make the clutch engage. I have the vertical sides of the clutch and torque converter towards the engine and the vertical side of the belt on the same side. Any advice?

This is how I assembled it. Am I supposed to lube the clutch?

Thanks

What was on there before?
I looks as if you have a built in Gear reduction on that motor.

 

[chvyhs]

I don't think there's a gear reduction in there. I'll pull it apart tomorrow and check. Here's a pic from the top.

Here's a video link,

I still can't get my clutch and torque converter to engage. The tires were barely moving. The only time they really move in the video is when I move them by hand.

THAT is a 6:1 gear reduction...

no way it'll turn fast enough for the clutch (or any other cent clutch) to engage properly

Manual clutch torque motor for hill climbs?

Yep. Where'd you get the motor, OP? Definitely something "extra" on that engine.

I think you have this. Intended for cement mixers and the like; slow, steady revs on that PTO, not built for speed:

This sucks. Thanks for the help. Any suggestions on what I can do to make it work? I do have a lot of hills in my yard. Maybe just put a regular centrifugal clutch?

a reduction like that might not turn any clutch... does it have a built in clutch of any sort? like when idling does it spin? 2100 / 6 = 350 so you'd need a clutch that engages at a very low rpm and can handle that kind of torque :/

I'm so glad I found this because I have the exact same problem. I have a predator 212 with a 6:1 gear ratio and big off-roading tires. What could I do to fix the problem?

No...you don't have the exact same problem whatsoever. I suggest you start a new thread, or if you have a thread with this kart in it...ask the question there.

We'll need some info and posting here will just confuse and muddle up this thread.

Sadly.. all you can do to fix that is buy a new crankshaft and crankcover and swap the parts.
(I don't know the exact part numbers from on top of my head.. but I remember posting them not too long ago.. search for gx270 crankshaft on here)

But that's going to cost you a good amount of money.
So maybe you'd rather sell that engine as is, and buy another gx270 with a straight 1" shaft and w/o gear reduction box instead
(that'd fix the problem without sepnding money I'd say)

Use a jackshaft to reverse the ratio or crankshaft like suggested above. You could do a 2:1 from the engine then a 3:1 to the tires using a manual clutch. Sell the torque converter recoupe 1/3 of the cost to convert.

 

[itsid]

well JFive you're forgetting about the fact that his type of gear reduction does not come with a clutch..

so he had to step down (to a 1:1 ratio) add a clutch and then back to 6:1... that's simply insane!
(and likely even more expensive than buying the spares to convert the engine he has)

the one option left would be a 3d motorsport manual clutch IMHO.. hooked up and manually clutching as he goes.
but if it's indeed the 6:1 version I think it is, then he'll have a hard time running 1:1 to the rear axle (nearly impossible thanks to the axle diameter itself)

And he'd slow down... (adding another ratio even if only 1.5:1 and he'd be at 9:1 total)
so even that is a bit of a pain.

I did mention using a manual clutch like 3d Motorsport. Didn't forget you didn't read. Just putting options out there for OP to think over. When I said to go from 6:1 to 1:1 it's to put it back as it would of been not a 1:1 at the axle. I would have had to put say 10t on engine 10t on axle but I didn't say that. Maybe that sour puss face your making is affecting your interpretation.

 

[chvyhs]

I finally made time to take it apart. I may just sell this engine and buy a 13hp Predator.

I don't know why you did that or what you expected to find in there besides what's there. You could have looked at a diagram instead. Now you need a new gasket...

 

[chvyhs]

I can affard a gasket. No need to worry.

you're not getting the point.
With a manual clutch his ratio is already good'ish in most scenarios;
if anything he'd need to lower it's ratio further (say heavy kart or large rears) it's even likely he had gear even lower just to fit the axle sprocket.
so

Use a jackshaft to reverse the ratio ... You could do a 2:1 from the engine then a 3:1 to the tires using a manual clutch. ....

Does NOT make ANY sense whatsoever...

reversing the inbuild ratio back to 1:1 is just BS with a manual clutch
(that -being manual- works perfectly fine with low rpms)
the only reason to do so would be a cent clutch (or TC) in which case he'd need to then go back to a decent ratio yet again.. (which still is totally insane.. he'd loose enough power to just use a gx160 instead from all the jackshafts sprockets and chains)

And as a side note:
Oh it's "would HAVE been" not "would OF been" ..
see, I read that

FYI,
I have a 10 tooth at the torque converter and a 61 tooth on the axle.
