Engine mount

[trackdom]

Hi,

Ihave to report that I struggle a lot to bolt my Lycoming O320 to the dynafocal mount. Has somebody experienced difficulties at this stage of the construction..it seems the mount is not at all behind the engine holes and I have to force the bolt to come in...
Thanks

The trick is to squint with your right eye, hold your tongue in your left cheek and sacrifice a small farm animal.
Get one started and get the engine close to the mount, they will all go eventually, or attach the mount to the engine first and then attach to the firewall.

Itried this method but that doesn't work better.

OK, have you made sure that you have the correct engine mount for your engine? Make sure you have a dynafocal engine/mount for an O-320.

Assuming that is correct, have you tried the engine mount alignment pins? Here is an example:

They work well and can simplify a particularly stubborn installation like yours.

I installed (one man job) an 0-360 on the dyn mount and took about 2 hours. The trick I found was just getting the nut on with one thread, finding the right combination of bolt order and number of turns on the nut, slowly compressing the rubber mounts. Got it down to where the bolt hole by the #4 cyl was off by approx 1/16 of an inch. Then carefully used a little elbow grease for the last one. Maybe I got lucky finding the right combination, but certainly was an exercise requiring patience.

Mine went on so easy I was disapointed after hearing about how long it took I was prepaired for a fight and it just about fell on.

The third bolt (lower right) was the tough one for my engine. Once I was able to get the alignment close enough to get the bolt started it pulled into line.

I had to completely tighten the top bolts and that helps a lot to get the alignment better.

The last bolt (lower left) was much easier with all of the other mounts completely tightened up.

Oh yes. Let all your helpers go home, get a beer and relax. Then walk in the park. In the morning try to do it alone.
