Satoh Buck Clutch Alignment Tool

Replacing the clutch on my 83' Satoh
S470D @ 6200hrs. I have tried to locate
a clutch alignment tool without any
luck. I thought I'd ask here if anyone
knows if there is one on the market
before I hire a machine shop to make
one. The spline is .789" and the pilot
bearing is .587".
Thanks!

automotive universal alignment tool should work well. rent or buy @ auto parts store

Find someone with a wood lathe and make one out of a piece of dowel. The only stress on it is the minimal weight of the clutch disk, so it really needn't be made of steel.

this is what I use
mine has both metric an sae sizes

I always make my own out a piece of hardwood. To tight to buy one from an auto parts store and they never have the right one in stock.

I made one years ago out of an old shovel handle. Just used the bench grinder to size. I have used it on at least 5 tractors and have loaned it out. They are not a " precision" tool. I don't know about your machine, but on our old Ford tractors, when we do work on the clutch , recomend replacing the trany input seal. With the input shaft out ,just use it to align clutch. joe

I never use one, and if you try my method, you won't either. Lightly snug the pressure plate up so you can still move the clutch plate, then position your best eye dead center of the pilot bearing (use a good light). Move the clutch plate around until you see concentric circles. If you are centered you can see both ends of the pilot bearing, and when everything is aligned like a bulls eye the clutch plate will be in place better than with a tool. You can get it within a few thousandths.

Then tighten up the pressure plate. The other thing I do is align one of the splines where the side of a spline is right at 0 degrees at the top. Then align the input shaft from the transmission vertical to match. When I was a kid I would hold a three speed up off my chest with one hand and try to turn the output with the other to get the splines to match. The first time I tried to align the splines before I stabbed the transmission it went in so quick first time I couldn't believe it. Same thing with a tractor, get everything aligned and it will roll right together, assuming you have a flat floor to work on. It's a little tougher under a tree on boards.

If it's just a single disc clutch.... eyeball it. That will be plenty close. The only time I use an alignment tool is with twin disc clutches and that's only to align the splines of both discs.
