the sunroof on my 91 no longer operates correctly. the motor itself is fine, but the middle (idler) gear in the sunroof transmission is stripped. there are no markings on the transmission housing or on the gear to indicate part numbers.

what i'm calling the "transmission" is the assembly that is bolted to the output end of the denso motor. it also has the exterior limit switches attached to it. the version used in the 91 has three gears, while most other toyota models used a 2-gear version.

in searching, i come up with entire assemblies, ie, the motor, wiring leads, and 3-geared sunroof "transmission", but never the actual gears. the gear is plastic with a brass center hub. it stripped, likely from the roof not being lubricated by the PO, and the two gears it meshes with are all metal. it has 35 teeth, too.

i know it's a longshot, but has anyone had any luck sourcing this gear?

If you want just the gear you might be better to source it from the JY, it looks like it was made to fail so you have to buy a whole new trans/motor unit

for sure it is the weak link, the other two cogs are metal.

JY sourcing in the northeast is sometimes problematic, as a lot of cars from that era have already been crushed (the car was new 25 years ago).

like i said, a longshot in sourcing just the gear itself.

Oh I know all about it I'm originally from the east coast, lived in Ohio. Also I own a 93 celica and a 85 Camry, so hard to find, I get. If you do find one I'd recommend taking a metal gear along with the plastic. Maybe you could modify the metal to work

i did think of a metal gear, but both are significantly larger diameter than the plastic/fiber gear, so the ones from this style "transmission" won't work.

This looks like the same mechanism

i appreciate the effort, but i'm not looking for the whole assembly. just a source for the gear. you know, a "reduce, reuse, recycle" thing.

since everything else works fine, i'd love to replace the stripped gear. and i realize it may be a longshot. it isn't worth spending $50+ to fix it. maybe that means it will never work again. c'est la vie.
