Release / throwout bearing grease

[Panici]

1. What type of grease is recommended for the guide tube, and the release bearing guides?

• Bentley says to use a molybdenum disulfide grease.
  • A quick google says that moly grease may be too sticky and not allow the throwout bearing to slide properly.

• Pelican Parts says White lithium grease.
  • Apparently white lithium grease can't stand the high heat and will break down.

Suggestions as to grease type?



2. The Bentley manual says to grease the "release bearing lubricating groove". Pelican parts makes no mention of this.
I am not sure where the lubricating groove is. Please see attached pictures.

Thanks!

Check your new bearing- some of them come pre- greased.

That said, I usually just use wheel bearing grease- it's high temp,
it stays slippery...

The groove is inside the bearing sleeve, where it rides on the tube-
if it's not full of grease already,
you'll see 2 bearing surfaces, then there's a 'trench' between them
that you fill with grease.

It's not super critical- yes, do grease it, but in 10k miles, it's full
of clutch particles anyway...

<edit> duh, just looked at your pictures-
that's a different style of throwout from what I'm used to.
I'd just smear wheel bearing grease into the notches and
call it good.

Factory spec was MolyKote longterm 2, back in the day.

Maybe it's a sealed bearing? It came with my clutch kit.

There is a gap/opening between the edge of the metal flat surface and the plastic tube.

Yeah, but I have no idea what the current equivalent would be, and chances are I'd have a tough time getting it here anyways.

+1, Molykote longterm 2 is what is spec'd. It's a MoS₂ grease made by Dow Corning.

I used some Aeroshell Grease 33MS which is a MoS₂ spline grease that seemed fairly similar, but if you can't find any, Just use white lithium grease or wheel bearing grease, just make sure there isn't any different type of grease left over on any surface you apply the new type to.

I lightly greased the TOB tube, packed the slots in the TOB, and put a dab on the surfaces that contact the clutch fork.

I used Jig-A-Loo white lithium grease "Super Grease" in a spray can.
Says on the back that its High temp resistant.


It seems a little thin though :/


Trans is still apart (not for long) if you have another suggestion.

I'm not a fan of the spray on stuff, it's really thin and seems to wash away quickly. Most parts/automotive stores will sell white lithium grease in a tube or tub.

molybdenum disulfide is the main ingredient in most hard anodizing baths.
It's great stuff.
You can order that exact grease from McMaster Carr.

White lithium is crap general purpose "lube". Doesn't even hold up on a bicycles chain...

I tend to agree with this.

I ended up using "Motomaster Moly Extreme Pressure Grease".
