Mechanical Question about throw out bearing eaton fuller 6 speed?

[jamom123]

Hello all, I have a question about how to grease the throw out bearing on a eaton fuller 6 speed transmission. It started making some squeaking noises, I can't find any type of grease fitting it seems the bearing is encased. I tried greasing the tranny shaft to no Aveil. Any help would be appreciated thanks.

There should be a grease fitting at the bottom of the bearing.

If there isn't, I guess there's a possibility someone put it in upside down, although how they managed to do that evades me.

If it gets much worse, it's time to pull the tranny. If you go that far, you might as well replace the clutch.

Being a Freightliner I wonder if they may have switched to a sealed bearing.
Of course, that doesn’t change the diagnosis from Dr Greasey.

A few weeks ago I drove through some slushy snow and forced a decent amount of water in there. The noise went away for a while but it eventually came back with force. I will try to attach a photo of the bearing I Beleive it is a sealed bearing.

Looks like BigStickJr is right. There's no greasing that one.

Replace it before it grenades. How long until that happens? No one can say.

Thanks for all the help everyone. So according to what I'm hearing there's really nothing That can be done other than changing it correct?

IF getting it wet would help, I’d say hire WOM to drive it.
Unfortunately, that won’t do it.
Schedule the replacement soon.

 

[jamom123]

So I take it when it gets wet and stops for a week or so it's just masking the problem?

I don’t have a degree in greaseness, but I’d say yes.

 

[jamom123]

Have any of you ever changed this type bearing before?

Probably have.
Driveshaft down.
Transmission down.
Slide off,pray, inspect shaft, reinstall.
Since trans is out, you might as well replace the clutch.
A good shop I’d think 7 or 8 hours.Including clutch replacement.

You need a smooth, level concrete floor to do this on, or you'll be fighting the jack like crazy.

 

[jamom123]

Yes, thank you.

Have you done something like this before? Do you have someone who can help you?

 

[jamom123]

I've personally never dropped a transmission. But I do have someone to help me.

The very first step is to determine the spot where the engine usually stops. Because of compression, the engine generally stops in the same place each time. Start and stop it a few times. If the new clutch is manually adjustable, you want the adjuster to stop in that window so you don't have to try to bump the motor over a million times to get to it.
