It's my brand new pilot bearing seal, I kinked it while I was installing it, I didn't notice that I had one in place when I replaced my pilot bearing though. Never had any problems with it before so my question is, do I really need it?
My buggered up new pilot seal
Here's a few shots of the hole the pilot bearing goes in after I finally got the old one out. I was thinking that since it's just a seat for the outer race has long as it was tight it would be okay. There are a couple grooves I dug in though, it was my first time using a dremel. :/
Yes, you need a pilot bearing seal. It prevents the pilot bearing grease from flinging onto your clutch face and contaminating the disk from the centrifugal force.
I wouldn't worry about the gouges from your sub-par dremel work. I would just wipe it clean and smear a minute amount of rtv in the bore before tapping in the seal. The forces on the grease are fairly low since it is so close to the shaft centreline, so rtv will hold no problem.
Me and you both with this dremel nonsense lol
It does hold the grease in the pilot bearing so I does have it purpose but if you Dont run I I'd expect pilot bearing wear out faster once the grade flings out.
no you don't need it, i haven't seen any premature pilot bearing failures due to it not being there. so long as you use about a teaspoon of grease it will be fine. the grease stays put just fine and dust intrusion is not an issue that some say it is.
my clutch had about 80k miles on it from the first engine rebuild, no seal. clutch was fine as well as the pilot bearing. in fact the clutch still had over 50% so i threw it back in.
Hehe im running without one since i forgot to put it in. Car seems perfectly fine 4k miles later
Yeah, I ran mine for nearly 10k without it and it was just fine too.

I can dig it, and the more I examine the part and what it does the less valuable it seems to me, BUT, someone much smarter than I engineered this thing and I don't suspect they would have taken the time and resources to come up with some cheap $3 part were it not at least half way profitable for it to be there. I ordered one from RockAuto and it didn't even cost $4 after shipping and should be here by Wednesday so what do I got to lose?

That's what I was thinking too, maybe, maybe not? I'd rather play it on the safe side seeing as I had so much trouble getting out this pilot bearing I want this new one to last as long as possible!

C'mon man, it was my first time! I did it with the engine in the car, on the floor with jack stands and only had one flood light to illuminate what I was doing. That thing just wouldn't come out either, after I saw the damage I had done it was a rather bittersweet moment when it finally did too.
often i've seen more harm than good with the seal, because the input shaft nose usually dings it and rolls a lip or pushes some rubber into the bearing which is what causes the bearing to fail. or in some cases just someone fighting to get a transmission in for days when it was the seal the whole time.
i just don't bother with them anymore but to each their own.
