This is not a RV but a Pazmany, so I hope this post does not violate any posting rules. If it does, please remove it.
We are replacing sagging bushings in my friend's Pazmany PL-1B. The engine is a 150hp O-320 with Dynafocal mount, but we are not sure what type (I or II). However, the airframe engine mount has cups looking like engine block conical mount using bushings looking like Lycoming 71032.
71032 bushings have .5" hole but the mounting bolts are .402" like the ones used with Dynafocal engine mount with large cups. We are thinking using some type of metal sleeves over the bolts so the bushings do not deform too much under compression. I fount the following online from Great Plains website:
http://www.greatplainsas.com/i71032.html
However, Great Plains uses .5" OD with 3/8" ID metal tube as sleeves since it uses AN6 bolts (.371-.374"). Our bolts at .402" are not going to fit.
Is this a standard Lycoming installation? If so, is there a Lycoming kit (bushings, bolts, washers, sleeves, ...) to correctly mount this Dynafocal engine to its engine mount with conical cups? Part no. for the kit?
If not, any suggestion on how to correctly install these bushings is welcome.
