 |
|
I am having trouble finding the exact location of the two motor
mount attachment points that are in the middle points vertically.
The upper center point and the two lowest ones are clearly located on
7-F-7 but the middle ones are not. I am new to reading these plans so
I am sure it is me. Jerry

Are you using the old style "shelf" mount or the new ring mount?

Neither. I need this info so that the engine mount for a RotaMax 2 rotor engine can be designed for the 701. Jerry

Is this the 1.3L? I have also looked at this engine. Just not exactly sure about fuel consumption.
Weight/power is definitely a plus.
Let us know what you find out.

Jerry,
Print 7-E-1 shows a total of 5 attachment points to the firewall, 1 centered up top, 2 mid
outboard and 2 lower outboard. Assuming your installing a 912 could you not just use the
dimensions used on 7-E-1 to locate the mid outboard attachment points, the dimensions agree with
7-F-7?

Thanks Art, Since I am not installing a Rotax I had not studied that
page but most of the information I needed is there. The only thing
not given is the vertical location of the thrust line. Jerry

Jerry:
I've attached a picture of the left side of my 912 ring mount. You can see the tab sticking out to the left where it will be bolted to the firewall. The bolt goes through the firewall and through a bent steel plate in back which also bolts into the flange of the firewall. Presumably whatever mount you're building could be attached the same way.
Incidentally, the previous 912 bed-mount mounts a little differently right here. The mount tab sticks up rather than to the left, so it overlaps on top of 7F7-1SP. That way the bolt goes through 7F7-1SP as well, which seems a little more durable to me.
Hope that helps. Drop me an email offline if not, or give Zenith a call.
John

John, thanks. That helps a lot. I notice that you have installed
7F7-5 firewall stiffeners at an angle instead of vertical. Does that
have to do with the Rotax installation? One last question, what is
the capacity of the Rotax oil tank? Thanks again, Jerry
