Hi
In the process of aligning the cowl to the spinner, engine sag came in mind. so a few questions around this are open for me. Any input helps, thanks!
Basic info: IO-320, Vans LORD mounts, engine hangs since 16 month (without prop), Senenich metall prop.
- Do the engine still sag, also with the new LORD mounts?
- By how much?
- Is it a "cosmetic" problem or is it important that the trust-line gets corrected after a engine sag occured?
I think there are two possibilities to go on:
1. Build on and make a straight fit, wait until engine sag occure, then if neccesairy shim the lower engine mount. This would give a nice fit and a correct trust line.
or
2. Build in a positive engine sag of a certain amount, wait until the engine sag and cosmetic wise all is fine and live with the trust line angle.
Or you tell me, that I do anyway not recognise a trust line change by such a small amount![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
