Grease on Input Shaft Splines?

[Doc_Mello]

So, when installing a new clutch, do you add a bit of grease to where the input shaft splines meet the clutch hub teeth?

Yes, no, maybe not? The RV6 instructions say to add a very small amount of the Exedy grease to the splines, but I’ve gotten mixed answers, so, let’s see what the community says!

Apply a very small amount, place the clutch plate on the splines, slide it a few times and then remove it, and then wipe off any excess that is not on the splines. It's what I've always done, and I've never had an issue with a contaminated clutch or otherwise.

Great tip!

Great tip!

It’s metal to metal and it slides on the shaft so why wouldn’t you I guess???
I mean, I do and probably will again someday.
Engineers, please feel free to crush my inferior intellect with some reason why you wouldn’t. And……. Go!

This is the way.

My apologies.
Yes I did follow what @ManitobaSI says here. You do not want three pounds of lube thrown about in there.

Small amount, yes. You definitely don't want to leave them dry, it will wear grooves into the input shaft splines and/or cause irregular engagement/disengagement from the disc not sliding easily.
