A garage door opener supply or repair company may have a spare gearbox
housing available, but cracks in that kind of plastic can usually be
fixed with epoxy, although it's far better if you reinforce any repair
with fiberglass or nylon cloth. Clean off all traces of oil and
grease, roughen up the plastic and use slow-cure epoxy because 5-minute
epoxy doesn't cure right unless it's mixed almost exactly right. Also
any places in the plastic that stick out and have screws going into
them should be reinforced with metal tubing (hobby shops and real
hardware stores sell brass and aluminum tubing) epoxied over them.

I spotted another larger crack near the top of the part of the
housing where the motor shaft enters. Squirted some lithium
grease in it.

It would be a hardship to replace it, so I'll try to nurse it at
least thru this winter. The surface-prep, epoxy stuff I should
be able to handle. Have to see about the metal tubing.

Assume it dies by 3/05. It is a simple chain-drive 1/3 hp
opener. What brand and/or model could I get (for reasonable
$) to replace it?

Can't thank you enough for your help ...

Salut,
Puddin'
