Knockout kit

Stub shaft doesn’t go into the internal bearing

The inner bearing is for the stub shaft to go into and ride on.
Looks to me like the oring and holder go inside the stub shaft.
I have an old stub shaft here and their is an area of the internal section with no spline which is where this gizmo sits.

Ok correct, on the crank before the male splines start there is a smooth surface where this o ring could sit. IF not the grease would get pushed out through the splines

Sorry, I'm w Knappattack. Looks like a Black Friday Special to me.

TIME will tell . But they do work , how long will they last before they need to be repacked , who knows

Look at the pictures I posted NYT, The stub shaft slide into the internal bearing, how does it do that if you slide this collar on it like their picture shows?

The collar looks to be holding the o-ring internally, but your saying the o-ring goes on the crank which makes more sense and that I can understand, but then what is the purpose of this steel collar with the internal o-ring in the photo? Is the collar a rouge to throw people off?

The photo appears to have the collar slid over the stub shaft where it should slide into that internal bearing, which to me makes no sense at all.

Sounds to me that guy could then get an o-ring, grease up the splines with grease and call it a day if thats the case. No need for this "kit".

U need to go back and look at the pictures. The collar is inside the stub shaft . The collar holds the o ring in place on the stub shaft when u slide it onto the crank. Simply putting a o ring over the crank to seal up against the stub shaft I can’t see working. I ve only installed one for a customer so we will see. NExt one I do I will take pictures. I’m not saying this is a long term solution but initial impression is it works. Created by Dave at TAPP so I’m sure some it’s been thought through some what.

Hurricanes acts as a harmonic balancer. I’ve installed many of the noise reduction rings

Alright that makes sense if the ring is on the inside of the stub shaft. It looked from the pictures that it was on the outside.

Thanks NYT!

Once I zoomed on the picture closer I can now see how the collar is inside the stub shaft. Makes total sense now.

I ordered a couple kits to see how they perform. Sorry for the confusion, and thanks NYT for the explanation on it.

I was kinda scratching my head wondering why you weren't on board as it made sense to me....

I should have one on Thursday. I will post pictures if no one else has.
For $50, I figured I would give it a try. I have spent more on less.

Yep, everyone has to have the trick of the week and see what its all about.....

This is what it looks like installed.

I would say there is pretty good potential that the grease stays in the splines judging by the effort it took to install the shaft with the ring installed vs. without.
I think it took out about 90% of the rattle. That is listening to it in the garage, with the side cover off. It will probably be better outside on the snow.
I also wonder if this will help prevent the stub shaft from moving inward when blowing a belt? The grease is now filling the hole and helping prevent movement of the shaft. Maybe???

Mine have been shipped, but I dont have them here yet. Is the collar pressed into the stub shaft? I hope there is a bit of interference fit there.....
