Jeff Scott sent me a couple of drawings for a engine mount. jscott.pla...@gmx.com
I understand it is from Rand/Robinson and it is labled for use with the KR-2S and the Continental O-200A engine with the caveat (warning) that if you use a alternator on the bottom/rear of the engine it might/will interfere with the lower cross bar of the mount, in which case it would need to be curved somewhat. (note) The verticle distance from the top firewall mount holes to the bottom firewall mount holes is 13" as per the drawing. I altered my KR-2 mount demensions for my Original KR-2 by reducing the width of the top firewall mount holes from 30" for the KR-2S to 28" for the original KR-2 that I have and left the bottom holes at 26"across. I also increased the verticle spread from 13" to 14-1/2" by raising the top holes 3/4" and lowering the bottom holes 3/4" because that is what it was on KR-2, N4DD and the bottom cross member cleared the alternator just fine. The KR-2S drawings that I have, show the firewall as being 1-3/4" wider than the KR-2 drawings that I have. I also made the mount 10-1/2" deep from the firewall to the face of the isolator mount bushings. The drawings show 11-1/2" from the firewall to the aluminum engine casting and if you add the Continental isolator bushings you can subtract 1" from that depth. I have made my construction jig universal in that I can assemble any one of these mounts in the same jig by using the appropriately marked holes just in case I need too.
