what is factory new limit overhaul?
Ref. No. 128 shows that Lycoming determined that the clearance between the cam follower and cam follower roller pin should be .0002″ to .001″ for a new part. Lycoming did, however, allow a part worn up to .002″ to be considered as serviceable. The FACTORY NEW
LIMIT OVERHAULS done at Radial Engines, Ltd. will only use parts with clearances which fall into the “new limits” category; that is, between the “Manufacturing Minimum” and “Manufacturing Maximum” for new parts. Parts whose measurements fall between the “Manufacturers Maximum” for new parts and the “Serviceable Maximum Allowable” figure will not be considered acceptable for our overhauls.
