Installing assy case.
I installed the assy case. I made sure all of my timing marks were lined up, all of the nuts were safetied wired, tabs bent over on the idler shaft nuts, crankcase gear retainer in place. Fuel pump plunger is installed and lubed up. I got the gasket ready and put Locktite gasket sealer on both sides. I installed the assy case down over the tach shaft and then made sure the oil pump drive shaft lined up with the crankgear slot. I lowered it down into place and everything fit. I installed all of the 1/4 bolts that bolt it all down and torqued to 96 in/lbs. After I got this all done and started putting on the assy, I got a e-mail from a gentleman also building a ECI titan. He torqued his oil pump body nuts down to 204 in/lbs and one of his studs broke! The torque setting is more than Lycomings 150 in/lbs. It's wrong and ECI is going to get this resolved. I torqued mine a little less but over 150 in/lbs due to the holes not lining up with the castle nut. I tried combos of washers and different nuts but nothing came close. I even tried to move the stud but that was asking for disaster. I remember torquing one to 180 in/lbs to get it right and the rest were 160-170 in/lbs. This is close to the setting. The standard torque for those size and thread of bolts is 204 in/lbs. The mag studs are the same size and they are torqued to that setting. Why his stud broke is a good question. It sounds like ECI is going to take care of him and get him a new case and change the valve in the manual. I was glad to here that they took good care of him and I have always been happy with their service.
