YM1500D clutch squeal?

[chuckyp-HT]

I just had something start happening similar to the recent YM155D clutch noise post except with a squealing sound rather than a clattering sound.
I was helping a friend move granite yesterday with my 1500D and the tractor started to squeal whenever I pushed in the clutch.

I was thinking a bearing, but somebody on the other post mentioned an adjustment.
Does this sound like something an adjustment might remedy, or more like a bearing replacement or some other repair is going to be in order?

Same old, same old, throwout bearing. This is a common malady on any "stickshift" vehicle. The clutch adjustment, 1/2"-3/4" pedal play just assures the bearing does not constantly turn and cause premature wear, same as riding the clutch would do.

OK finally got around to resolving myself to splitting the tractor to take care of this bearing issue.
I think my tractor is a hodge-podge VN job because when I was working on the front 4WD assembly the internals were clearly from a red version. Looking at the parts in the clutch assembly though, they appear to be from a green model.
At any rate, the whole bearing and carrier assembly is a seized-up rusty mess. I cant even turn it at all by hand. From the wear, it appears the bearing was seized and the bearing cup was actually spinning on the springs of the pressure plate. The pressure plate is pretty rusty too. The clutch disc itself actually looks pretty good with a lot of material left on it, but I might as well replace it too while I'm in there huh?
I posted a picture of the bearing and carrier assembly to make sure it looks to you guys to be the correct green part. Considering the weird problems I ran into with my stub axle parts, I want to try to avoid any surprises by ordering the wrong parts.
I also wanted to ask if there was anything else that one would typically address while the tractor is torn down this far. I think I may be leaking a little oil out of the rear main seal but I'm not sure how much extra work it would be to replace that or if I even want to open that can of worms considering how small the leak is, if it's even coming from there at all.
Oh, and does anyone know the automotive equivalent clutch pilot tool that I need to use to line up the new clutch and pressure plate when I install them?
As always, your input is appreciated.

OK yeah I know I got no replies so I just jumped into the job awhile back.
Replaced the rear main seal, the clutch, pressure plate, and the whole throwout bearing and carrier assembly. Also cleaned all the gunk out of those hard-to-reach places.
The clutch looked pretty good, but I figured might as well replace it while I was in there.
It didn't seem like I needed a clutch alignment tool, I just used the driveshaft itself to line everything up before tightening down the pressure plate.
Everything is back together now and running great so far...

Good for you, and thanks for the follow-up.

I missed your question before but for future clutch jobs--

You just use the tractor's clutch shaft. It is just splined into the transmission. Just pull it out of the transmission, allign the clutch &amp; put it back into the transmission. almost all Yanmars are that way.

That's exactly what I ended up doing, and it worked perfectly. The only reason I asked about it in the first post was because I didn't have it apart yet and the clutch replacement directions on the website mention a clutch tool. Thanks!
