There may come a time when you say to yourself, in Yogy Bear's voice, F%$k the slipper clutch, BOOBOO!!!.... And GO DIRECTDRIVE.
I think I fully understand the principals behind the slippers application, yet for my needs, the slipper clutch is more hassle than it's worth. This mod is not for
newbies who don't know about the splipper's purpose and safety benifits.
And yet ironically, it's the newbee that gets the most out of the whole thing. It spares him/her the frustration that inspired the mod to begin with.
So...if your a newbee, find out what you can about the slipper's purpose from numerous sources to know what's up with it, in general. If you read this entire
thread's content, you should be able to form your own opinion.
I think if you compete in full out racing and need slingshot exceleration while getting big air all day, then keep the slipper. Otherwize, why not check out the
confidence one gets from having HP at the trigger rather that the slipper.
The danger to the tranny is only present if land your jumps at a high rev, which you should'nt be doing anyway. So don't do that!...lol.
Now,.. I don't need to be dependant on splipper parts any longer. And if I change my mind and need a slipper setup, I can simply swap setup's in 5 min.
There's few things that compare to the hassle of discovering you have a glazed slipper pad, a self loosening shaft nut, a scribed slipper ring, or a melted spur
gear hub.
Before running the directdrive spur gear, do a re-mounting of the flywheel and clutch bell. Just be sure that your flywheel is seated very firmly,
and the nut
is on tight. Use a tiny, tiny amount of blue thread lock on the shaft threads, near the collet. Make sure that the blue doesn't get to the bearring
behind the collet. By doing this, you can be extra sure that the flywheel is secure and able to hold it's own.
If anyone would like to know about making thier own directdrive spur, Then just read the following post, below.
I'm gonna make this discription in quick form to save a little time......lol.
==After losing the last draft of this post I typed into cyberspace, I figure anyone can post questions for any area's of my discription that need clarifying.==
Supplies, Parts, and Tools.
1) SteTo begin, get another spur gear w/ slipper pad, spur gear bushing, that little hex washer that goes up against the bushing, and the aluminum
back plate for the slipper ring from your LHS. The reason for the this is that you'll have a back up spare in case you have any problems with getting this mod
in place.
2) Now remove the engine and spur gear assembly from the truck then set aside. What we are going to do is basically this: "Lock the spur gear to the
back plate". If your good with tools persay, then this mod is about a 5 on a scale of 1 to 10. The important part to this mod is getting the spur gear and the
back plate to be well-centered while being fastened securely using at minimum, two machine threaded bolts.
3) You'll also will need to locate a tapping bit or two in case one snaps.(they are very easy to break at this size). They need to be matched to the size
bolts I suggest. There is some room for variance here but, you want to sellect bolts that are not longer than the thickness (depth) of the spur
gear/backplate assembly. In fact, I would suggest 1/8 in. shorter so there's less chance of any obstruction in the rotation path of the spur. I also
recommend an 1/8 in. maximum size tap for this mod.
4) Of course, if your going to proceed, your going to need to pre-drill the tap hole locations with a 3/32 in. drill bit so a tap can be used. Having a 12 in.
long 3/32 drill bit about now, would be great because, you would be able to drill the pilot holes through the bulkheads while the new spur assembly is
pre-mounted, giving yourself a perfect alignment and centering position for your tap locations. I used an extention w/ drill bit chuck.
5) Needless to say, this is the way I recommend you tap the spur assembly. This, knowing that most of us don't have a sellection of foot-long drill bits.
I'll suggest a plan B later.
6) The last thing we need is a small piece ( 2 x 4 in.) of sanding screen.(Having some extra screen is advised so you can have this reserved for other
spur sizes that have there own assembly.) The screen is used to take up the thickness of the removed slipper ring, and provide a good
bite against the spur.
