All,
I’m in need a a starter ring gear support for my O-360 A1A (narrow deck), and I don’t really know what my options are due to my inexperience with Lycoming engines to date. I’m hoping to be at a point to overhaul my engine this year (under supervision, but I really want to learn more so I want to do it and I own another flying airplane, so finishing the build is 2nd priority to enjoying the build and learning) but I’d need to source a few of the things that were missing from the engine I bought. I see from the parts catalog that my engine calls for either an LW-16064 or a 75221. See screen shot from the parts catalog.
What is the difference between the two?
Some clues might come from the wide deck parts catalog:
It seems like the difference is a “1.91:1 drive” vs. a “2.5:1 drive”…. I’m not really sure what that is referring to. Is that referring to the alternator pulley?
If I were to purchase a ‘lightweight flywheel’ would it work on my engine?
