Jacobs R755 Cylinder Specs?

Tue Jul 31, 2012 3:10 pm

Does anyone have cylinder overhaul specs for the R755? I'm looking for bore size and choke most of all.
I'm also looking for a usable (ie. non-collectable, copy OK) overhaul manual with tables of limits, but for the moment I just need the cylinder info.


Thanks

that bore should have .008" + or _ .002"
I will check to see if I have fits on tha engine. It is not one we see a lot.

You can buy manuals from Radial Engines, Ltd or through Essco in Ohio!
