cub throw-out

[mushman]

I have a 55 Farmall cub, I have replaced the throw-out in it 4 times now and am lucky to get a year out of it. Prior to installing it, I have soaked it in oil for up to a week, I also hired it done by an IH dealer and again by a tractor mechanic. I have replaced all the linkage and fork as well as the pressure plate and clutch. but results are the same. I am thinking that the aftermarket parts are just no good and thinking I will replace it one more time and sell it. I really do not want to as it has sentimental value, and I like how it operates. Hoping that someone may have a source for a better-quality part than Steiner’s offers.

Is it the real ball bearing ,or the chunk of carbon style? While I didn't like the carbon block style from the first one I saw,I do have to say any I've replaced did have a lot of time on them.In the past few days I ran into a problem with a throwout bearing for a LowBoy 154.NOT my favorite clutch setup,nothing like a real Cub.The guy bought his own parts,but I don't know where he got them.The pilot bushing was nowhere near close,and the throwout bearing makes crunching noises when I spin it by hand.The old greasy one felt and sounded good,so back in it went.I've done a lot of clutches and shafts in these 154/184 tractors,Whoever designed that setup should be hung up on a wall of shame.I've done a lot of clutches in the real cubs over the years too,but nothing premature.

I know this is obvious but just gonna throw out (no pun intended) that adjustment and not resting a foot on the clutch pedal saves wear on the bearing. No brainer but thought it should be noted.

If the carbon type you need to check the fingers on pressure plate. You may have a sharp edge eating it up.

Failure is almost always caused by one of two things......#1 riding the clutch,even resting your foot on it and letting the throw out puck contact the fingers on the pressure plate....or #2 the fingers are not adjusted perfectly even with each other. We have Cubs with hundreds of hours on aftermarket graphite throw out "bearings. Hundreds of hours

Please explain not following , why did you soak the throw out bearing in oil for a week ? There is a grease fitting located vertical from the inspection cover, no ?

Thanks, i will check it closey when i get it split...again! But it has had 3 different plates as well..but worth checking.

I appreciate any suggestions! I am very careful about foot position, so is not that issue.

Sorry, is the grafite block style

I agree with those above:
Clutch adjustment.
Riding the clutch.
A pressure plate fork with a sharp edge.
Pressure plate forks not adjusted properly.
Then there's the part about pumping a new throwout bearing full of a cheap, thin grease a few days before the bearing is installed.
Then using that same thin grease every time the throwout bearing is greased.

I've adjusted pressure plate forks laying on my back under the Cub.
It's not what I call a good time, but it's do-able.

I have a 184 and really hope I never have to replace any of the clutch innards.
Those things (the whole 184) are a pain to work on compared to an F-Cub.

Thanks for the information, but the fingers appere to be perfecty lined up, and no foot even close to the clutch. The origonal block lasted 60 years with me driving it for the last 25.

Did a clutch throw out for a neighbor once. Graphite style. Fingers looked fine. Last about 5 hours. Took it apart and carried back to dealer I bought from. Great dealer. I was thinking it was faulty. Showed him and he asked if I changed plate. No it was fine. He replied that there was an edge on a finger. Change plate. I did and all was fine. He said the bearing would last until a finger got an edge and that would eat them up. Only experience I had with one.

There is a spec, a dimension from the tips of the pressure plate forks to the pressure plate.
I don't have that info with me right now.
And there are two types of pressure plates.
One of those is not adjustable.
I hope you can get it lined out.
It's frustrating to keep having the same problem.

You need to soak the Cub graphite "bearing" in oil for 24 hours at least before installing it,then grease it.

That was the other info the dealer told me. He was not in when I bought it.

You're right on that.
That was bad info I gave above.
Soak in oil.
From then on use thin grease.
Duh.......

throwout bearing for a LowBoy 154.NOT my favorite clutch setup,nothing like a real

I'm generally an IH fan, but the 154 is NOT their finest hour. Too big to be a lawn mower, too limp to be a tractor. Wouldn't give ya a quarter for a trainload of 'em.

There is a regular release bearing available for the cub, not the graphite one. I have installed a few of these. Don’t have numbers in front of me but a little research and you should be able to find one.
