In the service manual for 1967 Coronet, under sections 21 and 6 related to 4 SPEED and CLUTCH installation there is reference to this grease.

The CLUTCH section calls it "special long-life chassis grease or Multi-Mileage Lubricant, Part Number 2525035".

Might be answering my own question, is this it?

Thanks.

Long time since I've looked, but yeah, some bearing grease has fiber in it. The fiber tends to keep the grease itself, in place. Should still be available.
 
wish i knew where to get that "fiber" grease. i don't think anybody makes it anymore. works very well for wheel and axle bearing grease in our old cars.
 
We used to use a fiber type grease when I was a kid to grease equipment. The trouble with it was if it sat for very long it would start to separate the liquids and solids, but that was 40-50 years ago. You can still buy wheel bearing specific grease but I don't know much about it. I've been using a polyurea synthetic grease for the last 30 years an had very good luck with it even in wheel bearings.

Lew I may still have a can of that grease around here, not sure. I'll look for it when I get a chance. That stuff was sticky, stringy stuff. Very hard to wipe off.
 
I still have a can of that stuff on the shelf. Always wondered if it was better than todays stuff or not.

i've used the old valvoline 644. black and stringy and i used to curse it,...lol. tried some of the modern lubes and they don't adhere to the bearings, especially axle bearings. the modern stuff is thin, gets hot and runs off; which is a bad deal for the timken axle bearings and brake shoes. if you have some you don't want i'd be interested.
 
Just a guess here..... but in 1967 those "stringy fibers" were most likely asbestos.
 
I doubt it was asbestos, that would be like adding sand to oil to make it thicker. Not very slippery.
 
You almost had to pinch it off as you were removing it from the can.
It tried to pull a lot more along with it.
The very best for packing rear bearings in an 8 3/4.
I haven't seen any in a long time.
We had a can of Quaker State.
 
Thanks for all the replies, I tracked down the Sta-Lube SL3131 so we'll see how it works.
 
Most of the heavy duty or high temp lithium greases I can find have a NLGI grade of 2. The SL3131 is rated 2.5, maybe that's the key difference that makes the short fiber better?

still got a can of the q/s short fiber,Haven't tried to get in 10 yrs. Maybe I better be a little more sparing with it.lol
 
It don't ooze, it sticks together like the Blob.
I mean like in the 1963 movie.
Even if your rear axle shaft seals leak, rear bearings packed with this stuff will slow such a leak that you won't notice for a long time. It has a unique feel in the hand, not at all like regular wheel bearing grease. So incredibly sticky...gummy...and thick.

Prob'ly, cuz it don't oooze out the first time things get really hot for some reason like heavy heavy brake usage in racing.

Lew I found the can, I isn't what I remembered, it's the short fiber orange-ish looking stuff. You can still have, if you want it.
 
The stuff I have looks like tar and has about the same consistency. I sometimes wonder if it it too thick and sticky.

Thanks X 10! The table on thickeners is very interesting, and the inclusion of sodium at the very bottom explains why the short fibre is obsolete - apparent lack of resistance to moisture or oxidation. For an NLGI grade of 2.5, the green 1391K1 with clay thickener looks like a good choice and it's also good up to 400F. There are some lithium greases graded at 2.5 but with a lower temp range, as well as silica greases with temp ranges comparable to clay. Darn, wish I'd seen this table sooner as the SL3131 is on its way but I will go ahead and get a tube of the 1391K1 for comparison.

Considering the technological advances in lubricants over the last 40 years, I can't help but wonder if the Valvoline BG-2 part No.644 fiber grease that I have may not be obsolete.
