Model 86 with a K-301S

[JSedlacek]

I'm new to IH cubs, picked this model 86 up for $125 with a blown clutch. Guy said the motor was rebuilt and he blew the original clutch after 3 hours, that was 8 or 9 years ago. I got the the motor running like a champ now and bought a new aluminum clutch disc and a new drive plate. But my question is, is the output on the motor correct?

No, that long yellow part is incorrect. The original setup is much shorter. Also the aluminum clutch is a bad idea if its a working tractor.

What would be the correct part?

I know this model came with an 8hp from the factory so the 12hp in it is incorrect.

Also what clutch disc is better?
I knew I should have joined this forum before I bought a clutch disc lol.

My first ever CC was an 86 with a K321,,, so, the K301 is no problem,,,

If this tractor is going to be used for regular yard duty, a factory clutch set up will serve you well for many years.

It would appear that not only is the engine the wrong size (for an 86) it is also the wrong style. I'm not saying that this engine won't work, it's just different (the engine in the picture looks like an "AQS" engine). It really burns my toast when someone cobbles something together like this and then passes it on to an unexpecting victem.

I don't have a picture of the correct part, but someone should be along shortly who does. The "adapter" that should be between the flywheel and the 3 pin driver is aluminum and very different than what is in there. There should also be a screen on the flywheel to keep the enging from sucking up all kinds of crap to clog it up.

I'm more concerned that if you put the right parts in where they should be, your drive shaft may be too short.

Hopefully the po hasn't screwed things up so bad that we can't help guide you to get this back on track with minimal effort and cost.

It looks like someone has incorperated a bunch of BM's BS tips and tricks into this machine.


Take another picture from about the same angle only pull back a little so we can see more of that area.

Where is the hanger for your clutch lever?

I'll take a picture this evening, I'm heading to bed now. I have the clutch hanger off of it at the moment, the holes for the clevis pin are really oblong.

And yes I did buy my clutch disc from BM, won't ever make that mistake again.

Here's a better picture of the back end of the motor and the clutch assembly and also the clutch hanger bracket

Hmmmmmmmm,,, who knows 8HP engines in CC's??

Maybe the 8HP was shorter,, the PO used the 8HP adapter on the K301,,,,

In any case,,, I would bet the K301 is now too far forward to run a belt drive attachment
(you know,,, like a mower??)

Just guessing,,,

Actually it has an electric pto clutch and it lines up pretty well

We need more pictures...

I don't know if it's an optical illusion or what, but that blower housing looks odd from here.

Anyone know what it is for sure?

The engine looks like it's in about the right place, judging from where the flywheel is in relation to the frame rails.
