go kart clutch grinding

[invisible4good]

hello everyone, i have a 6hp briggs engine with a 3/4 shaft and a brand new clutch. was riding the other day, when i noticed that if i came to a stop or slow, the clutch made this strange grinding noise.. if i tap the throttle a few times it would stop. if i came to a stop and let it make the noise, it would shut down my engine. any ideas?

You should oil it every 30 minutes of usage. Have you done this?

 

[invisible4good]

ive been using chain lube... will this work?

 

[Doc Sprocket]

You need to use a syringe or similarly fine applicator, and apply 1-2 drops of clean engine oil onto the bushing.

Okay, check the c-clip on the back of the clutch. There is like a silver disc to cover the clutch on the backside and there is a c-clip holding it tight. When that c-clip comes loose, the disc will push on the boots and cause them to engage. I honestly just fixed this for my friends minibike. This tends to happen with newer clutches after they get hot for the first time.

All you gotta do is pop it back into place. If the clip is gone which I'm 95% it isn't, then you can get one from loses, or any place like that that sells hardware.

Just remember to just oil the bushing like Toystory says. If you oil anything more, the clutch is not going to work too well because it won't be able to engage for all the oil

 

[invisible4good]

wheres the bushing? i cant seem to remove the clutch either...

 

[klicky96]

The bushing is what the clutch rides on, it is like a goldish brown sleeve. Oil just above the sprocket away from the clutch.

 

[Doc Sprocket]

Have a look at the image I am attaching. The bronze (gold coloured) part is the bushing. You're trying to oil the outside of it. Basically, the outer sleeve of the clutch rides on this bushing. Where the arrow points to is a small end gap, where the bushing comes out a bit farther than the steel sleeve does. You want to sneak 1-2 drops of engine oil in there. (in the gap between the retaining clip, and the sleeve) Don't worry about trying to force it in, it will draw in on it's own. Don't overdo it- too much oil, and your clutch will slip too much.

ahhhh yess! the WD-40 on the bushing did the trick... at the moment i didnt have an oil dispenser, so WD-40 took its place. thank you all!

Just a word of advice on WD-40. It is not supposed to be used as a regular lubricant. For best results, use proper oil to oil the bushing

 

[dmaznic]

Actually WD-40 is NOT AT ALL supposed to be used as a lubricant! It is a water degreaser - 40th attempt at the formula

 

[Doc Sprocket]

Actually, water "displacer". But yes- it's not a particularly good lubricant. Use motor oil on that bushing. The WD40 will burn off in the first couple minutes!
