getting ready for spring. I've got the clutches apart on my 1982 honda 185s atc. I had a good solid engagement when I put it in gear, but when I throttled up , it slips for short time then fully engages. The centrifgal clutch pads are low and drum has three fairly deep grooves from the pads. The pads still appear to have some life left. The manual clutch has wear marks on the crown howsing that the slip disks get assembled in. Sorry for terminalogy, I hope you understand what I'm saying. The disks have worn side to side little grooves that look like they can be filed smooth. Other wise the disks look OK. The springs are just at their minimun tolerance. My Question is, which clutch is malfunctioning.

 

Just a thought, did you try adjusting the clutch before you tore it apart? You said the clutch slips momentarly, a simple adjustment may be the cure it needs.

Every part you mentioned has a service spec. If you don't have a manual, get one and measure your parts and compare to the service manual. If something is worn past the service limits, replace it. It may not be one single part or clutch ***'y thats "malfunctioning" but a combination of more than one worn part that is causing your clutch slippage.

 

Also, a likely possible cause of the clutches being to do that in the first place is from your selection of motor oil.

If you look on the back of a bottle of oil it has that circle i believe with jaso stuff and what not, in the bottom, they usuallly say, "energy conserving". Your going to want to get oil that doesnt say that, becuase the additives in that oil with the energy converserving part will make your clutch slip. And eventually it will just plain ruin it and then its time for a new one! not fun lol

goodluck, Sean

 

Hey, Thanks for that oil tip and how it might affect the slipping clutch, it's possible I might have an oil issue. Which clutch would do that?

 

Sorry, the centrifugal clutch would be doing that.

 

The centrifigul clutch is where your problem is. You can generally find new shoes pretty easy but finding a good drum can be fun. Good Luck!
