Lube for throwout bearing?
I'm putting things together and I'm wondering what I should use to lube the ID of the throwout being where it slides on the transmission snout. Thanks!

Re: Lube for throwout bearing?
Chassis grease works fine.

Re: Lube for throwout bearing?
I had been thinking of using NeverSieze. Good idea!

Re: Lube for throwout bearing?
I was taught in school many years ago, to use a light lithium... just a small amount.

Re: Lube for throwout bearing?
My experience with Neverseize is, if it’s left to the air it gets hard and clumpy. Maybe mixing with grease helps that. Any lube in that area is going to collect dirt and clutch dust and make the situation worse. I’ve always kept the snout clean and smooth. The throw-bearing doesn’t move very far. …….Mark

Re: Lube for throwout bearing?
Tim,
With respect, the '33s and 34s had them as well. It was with the '35s that the permanently-lubed throwout bearing was adopted. Perhaps you are thinking of the early '32 V8s that had a unique grease cup on the side of the transmission bell housing. The chassis parts catalogs and the lubricate charts use the word "grease" and so it is not a drip system since you are supposed to tighten the cover on the cup occasionally and refill the cup with grease every 1,000 miles. Further, with the early side version, its position is such that no dripping would occur. Last edited by DavidG; 10-30-2021 at 12:47 PM. |

Re: Lube for throwout bearing?
Are we talking two different things here? The OP asked about lubing the I-D of the bearing where it rides on the trans snout…..not the inside of the spinning throw-out bearing…. I’ll confess to knowing little about pre ‘50 cars……. Mark

Re: Lube for throwout bearing?
My observations: Never use "NeverSeize"! It is NOT a lubricant for moving parts! It is only intended for assembling parts that do not move-mainly threaded fasteners (bolts, park plugs, etc.). It helps prevent corrosion so bolts can be removed without damage.
At the shop where I worked, we had several pilot bushings that quickly failed due to being "lubed" with NeverSeize. Also saw the splines wiped out on a mower PTO shaft that were coated with NeverSeize. Usually these splines last the life of the equipment (years). Now a quote from the label: "WARNING: NOT for use on wheel lug nut or stud applications." |

Re: Lube for throwout bearing?
In the instructions for my T5 kits I have always recommended a slight amount of white grease.

Yes, this is what I was referring to. Thanks for the correction and by "Drip", you worded it correctly. I didn't realize it went into '33-'34 as well. The grease made it down to the input shaft by packing new grease into the cup? Last edited by Tim Ayers; 10-30-2021 at 03:02 PM. |

Re: Lube for throwout bearing?
For the very short motion of the throwout bearing, and the very high force leverage of the clutch pedal against that movement, lubrication for ease of clutch operation is not the issue. The problem is the ability of the retraction spring to pull the throwout bearing away from the pressure plate when the clutch pedal is lifted. If it sticks and leaves the throwout bearing in contact with the pressure plate forks, the bearing will spin constantly and may wear out prematurely. Such sticking may be caused by rust forming on the snout.
I use a very light coating of lithium grease as a rust preventative. Lithium grease is preferred for its' adhesion, water resistance, and heat tolerance. |
