Lycoming style engine mount accessory
cover
I am investigating casting an accessory cover
to replace the stock Mazda cover. So far I have roughed out a mock up in
foam. With the following objectives:
-
Replacement of stock Mazda cover & water
pump housing in one piece with integral filler cap.
-
To be able to bolt straight onto stock
Lycoming ( conical ) engine mount. Dynafocal possible would depend on
demand.
-
Relocate water pump & alternator to same
unit
-
No distributor drive height problem by
deleting distributor (crank Sensor)
-
Weight saving about 15lbs
-
No new aircraft engine mount to fabricate
weight saving and cost saving for many existing aircraft from 0235 to
0360.
-
Same thrust line as Lycoming
As this is still in the design and fabrication
stage.
I would be interested to have input from
anyone who is potentially interest to asses demand and my design
goals are on the right track.
PLEASE E-MAIL ME DIRECT

The idea has some merit (obvious reasons) but
has the following down sides:
1. It appears to me that it
will place the engine & redrive further forward than the Lycoming
it replaces thus altering the CG. (not a big problem)
2. The stock cowl will no longer fit the
airplane ( a fatal problem for fiberglass-phobes like me)
3. With the availability of efficient
Mazda engine mounts for many aircraft designs, there is little or no
weight advantage to using the Lyc mount.
Not a disadvantage, but the proposed
mount scheme is not necessary to get rid of the distributor. Mazda did
that long ago. (1986).
