Lycoming Torque specs

5 posts in this topic

Does anyone have a good source for torque specs for a Lycoming 8cyl engine.

Specifically its a 2H Lycoming 8 from a 1926 Gardner.

I really just need rod cap and main cap specs now.

I've tried looking online, but all I get are Lycoming aircraft engines.

Thanks

Tom,

You might try contacting the AACA Library in Hershey: AACA Library

OR

According to a post on another forum, this person, 'Buzz' in NE Wisconsin (Groom Lake area) knows someone nearby to him who owns a 1926 Gardner amongst other cars. Perhaps this Gardner owner might have some specs and/or extra parts?

Playing hooky from the Imperial? :rolleyes: CF

Torque specs were not commonly provided by manufacturers in that era, and seldom used by mechanics when they were. In the absence of other information, you can take the application, thread size & pitch, hardness of the fasteners if known, and thread condition into consideration and then consult on modern fastener chart for guidance.
