Suntour Derailleur Question(s)

Howdy all.
I've been busy the last couple days trying to clean up a Suntour V-T Luxe rear derailleur. Came off of a mid- 70's Raleigh Record. It's the "new" model with the aluminum cage. It's cleaning up pretty well - lots of Simple Green and Dawn. I have a strong hunch I'm the first to clean it.
My main question regards the jockey wheels: I'm strongly inclined to apply grease to the bolt (where there's metal-to-metal contact) but should I be concerned with any of the metal-to-plastic surfaces? The Plastic, BTW, is in really good shape. Curious, as there was so much grime and shmutz on them as to think they were really well (ab)used.

Also, I've searched around and haven't really found an answer (i like) regarding this derailleur's actual capacity. I'd like to repurpose it and some wheels (MTB) in a 1x8 setup. Wish I could tell you the tooth count on that cassette, but all I can recall for certain is that it's a Sram, purchased new, and ridden maybe a mile.
I figure I've got nothing to lose by trying it, and I'll be sure to let you all know how that works out.

I think this little project will be pretty cool when it's complete, and I'll add pics when it's done.

Use silicone grease around the jockey wheels if you're worried about the petroleum. Shouldn't be an issue though; chain lube is petro based. Have you looked at They have a lot of info on derailleurs.
I stop for people / whose right of way I honor / but not for no one.

A little bit of grease or oil inside the jockey wheels (there is a small aluminum bushing that goes inside the jockey wheel with a dust cover) will help stop them from squeaking and won't hurt the plastic.

Won't, I think. I'd be surprised if that SunTour will shift inward enough to reach the lowest gear in an 8-speed cassette. The total travel will be your biggest challenge. Good luck. PG
