0-320

Re lycoming 0-320

Lycoming engines manufactured before 1964 (1971 for 540 series) were of +ACI-narrow deck+ACI- design. These engines used cylinder base hold down plates and internal-wrenching type cylinder based nuts. The narrow deck design incorporated anchored through-studs that are of an earlier design and created crankcase fretting problems. Anchor through-stud engines should not operate past factory recommended TBO time's because of the possibility of crankcase fretting.

After these dates, lycoming engines became +ACI-wide deck+ACI-. Wide deck engines have regular hex type cylinder base nuts and a thick cylinder base flange approx. 3/8+ACI- thick. The thicker cylinder base flange makes the wide deck engines slightly wider then the narrow deck engine. The switch from narrow deck to wide deck did not chnage the model number of the engine even though cylinders and crankcases are not interchangeable. Another method you can use to distinguish narrow deck from wide deck is by the engine serial number. If the serial number ends with the letter +ACI-A+ACI- it is wide deck (e.g., L-82374-27A).

Body fit through-studs (wide deck) are a newer design. They support the crankcase halves with an interference fit at the crankcase parting surfaces and are tensioned at both ends with a 1/2-20 nut. This increases the rigidity of the crankcase and prevents movement and fretting.

To make are long story shorter, buy a +ACI-wide deck+ACIAIQ-

Rick,

The address listed is a correct address. I also sent him a message about
the engine and received a prompt response.

Don't know what to tell you but try again?

Hellow From Calgary:

I'm looking for an 0-320, running or runout. Not quite in the market for a
new $$$$30 THOUSAND something. Any information would be greatly appreciated.

I am building my fuseladge so will need one fairly soon.

Thanks

Note: The optional rear floor is a great idea but it does take a fair bit
of time. Lots of cross members and gussets.

Hi Bob:

I called Aero Recip in Winnipeg. They told me to phone Charlie, he used to
work for them.
Spoke to Charlie, he will sell me a 0 timed engine for homebuilt for around
$16,000. This might not be a bad deal.
Thanks for the reply.
