How Much Grease on Trans Input Shaft?

[Packin4]

I know you don't want to put too much grease on the input shaft or clutch disc splines but I've never seen a "quantity" listed. How much is "enough" without getting flung off? I will be using Liquid-Moly 47 a sticky, long-life, bearing grease unless somebody says no way. Thanks for any replies!

Less than you use for toothpaste. Remember a bunch of extra gloopy grease is just going to cause a bunch or dirt and dust to stick to it. Just a little is fine.

Hi,

I once asked a very reputable engine and transmission builder at RUF about putting grease on those splines or not, and the answer was: "the book says NO" , "the splines shall be dry and without dents". "The only place to be lubricated in that area is on the release bearing".
"The book" as in what the factory manual describes.

So I went with that and it works great.

Interesting about the release bearing lube. From what I've researched here they say grease the release bearing IF the inside is metal but no grease if the inside surface is plastic (ie. updated release bearing and guide tube). Regardless, good thing it's working!

Thin smear is all you need.
