Will torque converter fit?

[Tsuhrke]

A buddy of mine gave me a old Murray gt60102x92a. It has a Tecumseh OHH60 motor on it. To get the engine running I replaced the carburetor and the engine seems good. I tried the maiden voyage and it ran ok for the first 20ft. As soon as I turned up the slightest of incline, and I mean slight, the wheel would no longer turn and smoke came out of the area near the clutch. It rolls completely fine and I just lubricated the chain. The guy who gave it to me said it handled small hills no problem when he rode it as a kid. I was going to replace the clutch with a torque converter but I don't think it will fit. I'm assuming thats the problem (old clutch) . Sorry new to all this, been scouring the forums. Attached a photo

Could use a picture from the top and one from the side too please.

To get pictures orientated correctly take the photo(s) in landscape mode and or crop it a little, this is assuming you're using your phone.

Thanks for the quick response. Here are the photos. The sprockets are 10 and 60 tooth if that matters.

Looks a 30 series TC (with backplate and a 6" driven) should fit. Because the cover itself is the largest dimensions I'll give you those:

- engine block to outside of cover - 5"
- length of cover - 14"
- width of cover at widest point - 7"

Hope this helps you figure it out!

It won’t fit I don’t think. The driven won’t clear the tire.

Thank you guys for the quick response, the info was very useful. I ordered a new clutch to replace it with, and may try a converter down the road if it still has trouble

So I ordered a brand new clutch and replaced the old one. When I installed the new clutch, I put in the small metal key and the set screw. After the install, I lifted the rear axle off the ground and the tire immediately started to spin (sign of a old worn out clutch I thought). I drove the kart around and it operated exactly the same as before. It was fine on level ground, but as soon as I tried the slightest of incline the tire would stay stuck and place and not spin (except for the occasional burnout of grass and dirt). Small amounts of smoke would come out of the center of the clutch area.

Again I am new to all of this so I can't easily describe the parts, and I don't know what the previous owner might have installed incorrectly. In the first photo attached, the small nut with the nipple in the center spins when the tire spins, just wanted to make sure it was supposed to.



Behind the clutch is a small bushing on the shaft that comes out of the engine (second photo).



Third photo is the incline I'm talking about (if i drive left to right).



I'm 200 lbs, maybe it just needs more power? My friend who owned it before said that when he drove it as a kid it could handle smaller hills with no problem. I measured and I think I will never fit a torque converter. Not sure what to do next.

First of all... That looks like a typical cent clutch which has a bronze oilite bushing... that is supposed to be lubricated by oil....
Why oh why did some one add a grease nipple to the shaft...(I know the PO probably did) this is the reason why the smoke is occurring, as it has partly ruined the bushing....
ONLY oil is needed for these clutches and every 2hr of use. Grease doesnt work well and will destroy bushings, its meant for bearings( needle bearings on clutches typically).

What they did is the bolt that holds the clutch on is drilled out for a grease nipple and the keyway probably has a small hole drilled for grease to lubricate the inner potion of the clutch.... but this wont occur cause the clutch you have on there is a bushing clutch....

A possible fix to this is... add some oil to the snap ring area(while motor is off), move it back and forth to work it in. In a safe area start and see if you can let it idle with out taking off on you... Add some more and let is seep in. Might be able to rejuvenate the bushing...
If all else fails.. it might need to get a new clutch and a shaft bolt( use that old one to match a new one).
