Clutch and Set screws

[MikL99]

I have a new predator engine and a new clutch. I tightened down the clutch with the big bolt in the center of the shaft. I do have 2 set screws but there aren't any holes on the shaft for them.

Do i even need the set screws? Or am i doing something wrong?

Yes and no. ....do you have a keyway in the crankshaft and key that fits it and the clutch??????

If so. .... (and you should)....the set-screws are unnecessary. ....they are for applications where there is no end bolt......

Holes in PTO for screws are not a requirement. Screws are a good back-up to the bolt.

I wouldn't do it without a key in place. ........they cost pennies and you can probably get one at Home Depot. ......

Clutches and crankshafts cost a wee bit more.........

Just sayin'.......

 

[MikL99]

yep, i Have the keyway in and it fits. I was just worried about the set screws since they really don't do anything on my setup.

 

[Russ2251]

Almost forgot. Some set screws lock the key in place and also prevent clutch from sliding back and forth on PTO.

You are correct and good to go....just to be sure. ...make sure the clutch doesn't move sideways. ....but I'm betting it won't. .....

Maxtorque recommend either the end bolt or set screws, never both...

How come never both?

Ive been using both on my minibike clutches.. I figured the sets were a good back up and kept it from shifting if there was play at all..

Don't ask me, I'm just quoting what's on the label...

T Man did a vid on the subject... which I can't find right now...

Since I have the maxtorque label handy...

let me quote:

Set screws are only needed if the crankshaft is not drilled and tapped,
WHENEVER POSSIBLE ALWAYS HOLD THE CLUTCH ON WITH A BOLT AND WASHER.

underscores and capitalization taken from the label.

The thing is, I do not see any hint that you mustn't use both..
as far as I understand it there is no reason that you need both ...

Anything I miss here?

Just from what the label says, I think you could use both if you wanted to, but a bolt is the way to go if you can do it

 

[Axx3d]

OK.. wasnt sure if there any other reason than not needing if bolted.

I have seen enough things rattle free on these rigs so I plan on using both still.

It shouldn't cause a problem at all

 

[Poboy kartman]

Well. ...this should be so obvious it doesn't need saying....but you never know who might be reading this. ...so.....the main bolt should be well tightened before the set-screws are. .......

Doh!!

Hold on now.. i'm supposed to tighten things?

Mama always said i had some screws loose..

 

[Poboy kartman]

Doh!!

There are some folks that just defy logic.......and even after told multiple times .....just don't get it. .....so I thought at least one mention was in order......

Like I said. ....You never know who who might be reading this thread. .....

You said you wouldn't bring that up again, Poboy!

oh that video?

Are you sure that's it? I watched that one yesterday & couldn't find the reference I was referring to...
