Rebuilding Sno Thro Tractor- Coating parts w/Fluid Film

I'm currently rebuilding a 1971 sno thro, disassembled everything, cleaned everything thoroughly, inspected and replacing parts where needed. I was noticing the parts are in pretty good condition especially for its age with very little rust that easily cleaned off. Im thinking i did too good of a job in cleaning everything by removing all the oil and grease that was most likely protecting the metal from rusting.

I want to keep everything clean looking but also want to protect from rust. Things like the disc bracket to me look like it came originally coated in an oil film, and i just cleaned it all off. I used steel wool and dish wash soap on everything.

My thoughts are coating things like the disc bracket, gears, sprocket, even the chain with fluid film when reinstalling, just a light film coating. I just received the new thrust bearing and didn't realize they don't come greased so I'm off to Lowes to get some red and tacky grease, figured id use this grease on the hex and sliding fork shaft also. The only things i will keep clean are the friction wheel and the drive plate.

Any other ideas, what have others done when rebuilding these parts?

Great job on the rebuild of the machine and the detailed thread with lot's of pics.
Hopefully you get some snow and can post some pics of it blowing the white stuff.

I know it's not the original engine, but if you are planning on repainting the engine and tins anyway, why not go with a Canvas white.
Give the machine the original Creamsicle look.
You will probably want to scuff/sand the metal and use a good quality primer before applying your finish coat.
I agree, difficult to find a primer and paint that will adhere well and wear well on plastic.

Looking great, you are doing a fantastic job.

I would mask off the stickers, but correct stickers might be found here:

My 69 Ariens was a complete repaint, so I masked off all the stickers before priming and painting.

On the 74 Ariens, I was able to to maintain 90% of the original paint on the exterior of the machine and engine as well as all the stickers. I did repaint the rims, rakes, impeller and inside the auger housing and chute.
