engine mount

Yeah, it's just semantics. The mount was designed for the C90-14. The O200 came later, and fits the same mount.

Does anyone know what bolts to use for the 0200 engine mount to the firewall. The STC says to use the bolts from the Cessna parts manual but the ones in the parts manual are Allan head and are to big and to short.

I literally ran into that problem today as I was installing my new mount. The NAS145-15 bolts will not work anymore because the 4 firewall attach points on Cessna 140A mount (0451114-1) I bought from Univair does not have the recessed “wells” like on the original C120 engine mount. I found the new mount attach points are close if not identical to the C150 firewall attach points. I ended up going to a 58-66 Cessna 150 IPC and found that they use AN5-20A bolts. I installed mine according to the stack up orientation on the C150 IPC. Fits great. I put large-area washers under the 4 attach points and made a spacer to fit under the 5th center attach point to remove the possible slack.

The A model mount (0451114-1) is slightly “shorter” than the original mount to accommodate for the Lord mounts.
