I would think the jammed roller or gearbox is what caused the sprocket to
fail.
Started exploratory surgery this morning but it might end up being an
autopsy. In addition to the broken sprocket; the end of the gearbox
shaft was badly worn and scored indicating the sprocket key had failed
some time earlier. The one roller that seemed to be dragging was
gummed up but cleaned up easily and turns smoothly. More seriously
though, the gearbox flange that contains mounting holes was cracked
about 2/3 along its length. As I removed the motor/box assembly it
broke. Not sure this is economically feasible to fix since it is about
14 years old and the only affordable blades are Deltas. Ryobi quit
making them years ago and the aftermarkets are in the $60 to $70
dollar range.
I have seen the Dewalts in the store and thought they looked great.
Do you own one? My concern is the user reviews because about 1/3 of
the 145 users review rate it at two stars or below. Many of the
complaints sound pretty serious. When we started finishing the house
I knew the old Ryobi might not hold up to that much use. I have used
it fairly heavily since bought in about '95. I always saw my next
planer as being one of the heavier Jet or Grizzly 15" machines.
HOWEVER; given the economics of building a no-mortgage house and
watching 401 rollovers turn in to 201's, a big machine is out of the
question.
Are you or anyone else personally familiar with the Rigid TP 1300LS?
I have to admit Rigid was not on top of my list but reviews of owner
opinions on 2-3 sources look pretty good.

If I was going to spring for another portable planer, the Dewalt would
probably be my choice, mainly because of all the good reviews it's
received. However, I wasn't aware that it had racked up any significant
percentage of bad reviews; perhaps time has soured people's opinions.

I just took delivery of this bad boy:

I hear ya; however, Grizzly has free shipping on this machine right now;
perhaps saving $144 in freight charges would make the leap a little easier?

I am not; sorry.

Ordered a new sprocket for $1.98 + $8 shipping and handling. I had to
pretty much tear the machine apart to repair the gearbox (JB Weld is
wonderful) and get the chains and sprockets off. Cleaned everything
up and reassembled yesterday eventing and it seems to be running quite
well. With the cleanup and lube the elevation crank works better than
I can remember it ever working. I had to do a fair amount of fiddling
to get the cutting head parallel with the table but final cuts were
about .002 across the bed measured on the bed and on a piece of milled
walnut (accident, not skill). Main worry now is the badly scored
gearbox shaft that held the fractured sprocket. I cannot figure out
how it got that badly damaged with a keyed sprocket in place; and the
shaft turns much too slowly to have it happen in the moment of
failure. At least there was enough of the groove left to allow
installation of the snap-ring. If I had to replace the gear shaft, I
would have probably scrapped the machine.
Lesson: Pay attention to the minimum thickness requirement on a
planer's specifications. At one time the machine would not allow me
to drop the cutter to the 3/16" minimum. Wear must have loosened
things up because there were very visible gouges in the table below
the sprockets. I was planing some thin stock for trim and should have
been using my sled. Apparently the sprockets dug in, stopped the
chain and the drive sprocket failed. As usual---stupid me.
Fingers crossed
