Bolt holding clutch on crankshaft keeps loosening
 
I have a centrifugal clutch on my 11hp honda clone engine. We installed a graded bolt with loctite and the bolt comes loose after a minute of riding down the street. Any ideas on what could be causing this to happen???

It shouldn't move with loctite. Which one are you using? How much are you using? Are you sure you are tightening the bolt enough?

Torque the bolt down using some Loctite #242 blue. Make sure threads (and hole) are clean and dry. A lock washer wouldn't hurt either, but there's no way that should be coming loose.

What is make/model clutch?

chuggins08 08-12-2013 10:19 AM

its a noman enforcer clutch 10-tooth. I am using the blue colored loctite and using a lock washer....

chuggins08 08-12-2013 10:20 AM

I am tightening it as much as I can. Maybe the crankshaft was not dry when i installed the bolt with the loctite

Doc Sprocket 08-12-2013 10:22 AM

How are you holding the crank from rotating while tightening?

chuggins08 08-12-2013 10:24 AM

pipe wrench

Doc Sprocket 08-12-2013 10:26 AM

On WHAT?!?!

There is no place for a pipe wrench anywhere near an engine!

chuggins08 08-12-2013 10:29 AM

the clutch does not go all the way to the back of the crankshaft, so there is room behind the clutch to hold it with a pipe wrench

I think at this point .... :useless::useless:

Doc Sprocket 08-12-2013 10:44 AM

Just... no.

mckutzy 08-12-2013 10:50 AM

OH man I think we traumatized the mod... uh oh.. not good...

Doc Sprocket 08-12-2013 10:54 AM

Yeah, great. Who do I send the therapy bill to?

Russ2251 08-12-2013 10:57 AM

I recommend Dr. Ben Dover. Three chairs...no waiting.

Doc Sprocket 08-12-2013 10:59 AM

Think I've heard of him. He work with that Russian fellow, Dr. Trnyrhedncov?

Mount the clutch all the way on to the shaft.

mckutzy 08-12-2013 11:08 AM

Im assuming there is an integral key involved, but I cant see this hanging off there that far as all the way on.
Is all the setscrews backed off before install. Is the key fitting the keyway properly. (like maybe the keyway isnt machined properly)

chuggins08 08-12-2013 11:13 AM

it has set screws as the key. I am not saying its all the way on, the drum will not go all the way in the shaft, it just gets bolted onto the end of the shaft. The other part of the clutch can go all the way on, but that doesnt make sense to do that.
