Clutch bearing grease

[ronaldt]

What kind of grease do you recommend for the clutch bearing?

I use high temp wheel bearing grease

I do the same as Greg.In a pinch I've used regular grease that you'd put in your grease gun,but prefer the high temp grease.

I'm inline with the rest, hi temp wheel bearing grease. When truck manufacturers start putting disc brakes on, they recommended hi temp. Kendall Oil came up with Super Blue.

I'll tell ya how long I've had that tub of grease - I bought it when National Auto was around,about 30 yrs.ago.I bought it for new wheel bearings for my Massey Furgeson lawn tractor.That was a long time ago.I don't think I've used 1/3 of the tub yet.I think I used more grease on chainsaw bearings than anything else.

I agree with the comments for the most part. However, I would like to add the following, the "old timers" used the following term to describe the type grease they liked to use on bearings/open gears- "Long Fiber". While the grease did not contain any fibers they called it this because when they put a dab between their thumb and forefinger and pulled them apart slowly they would see long fiber like strands of the grease. In other words, it was extremely tacky and fairly thick almost a paste.

Today that term is obsolete but the concept is valid (i.e., thicker, tacky grease). The reason I state this is a thicker/tacky grease will resist slinging off a high speed ( e.g., 10,000 RPM) bearing especially an open needle pin type bearing as easily as a standard high temp auto bearing grease. Most greases in today's world will have a NLGI rating on the label. While this rating does not exactly(i.e., partially) equate the the consistency/thickness of the grease it is a weighted variable in the grading equation. The average good automotive bearing grease will generally have a NLGI rating of 2. Specialty greases will go up from their depending on the requirements (e.g., thickness, temp range, chemical resistance, lubricant solids used (e.g., molybdenum Disulfate(MoS2) vs. aluminum, etc). Based upon my research, a NLGI rating of 3 is generally a much thicker and tacky grade of grease. I found one good example but the working temp range is not good enough (low = 32 degrees F). but for a reference point the product is Dupont Molykote 1122. I attempted to contact Dupont a few times to see if they had a similar product with a lower working temp range but I got transferred so many times due to the person not knowing the answer/product line that I finally hung up.

Now for the really bad news... This grade of grease is hard to find and if you do... look out, the price is high. For example, the Molykote 112 product I mentioned is $50+ per 14 oz. tube.

For me, this price is way too high especially when I might use 1/3 of the tube in my lifetime. However, if someone does buy a product like this I would be interested in buying 1/3 or 1/2 the tube, just send me an email/message using this "House of Homelite" account . Bottom-line, I might be able to justify $25 for a lifetime supply... Ha!

I have no doubt people will disagree with my perspective and I look forward to reading their perspective.
