Aden,

I posted a comment on the Blog... I was installing my oil pump in the accessory case and was torquing the bolts to 204 in/lbs as specified in the ECI Hardware Manual when one broke! I immediately called Jesse at AERO who then had me call JB at ECI. According to ECI, the 204 in/lbs torque in the Hardware Manual is wrong!!! It should be 150 in/lbs as specified in the Lycoming Overhaul Manual.

ECI will be correcting the error on the Hardware Manual ASAP but also mentioned a couple of other errors as well. I have the other errors noted in my Hardware Manual but it is in my shop. Just make sure that you compare all torque specifications in the ECI Hardware Manual with the Lycoming Overhaul Manual and where they differ, go with the Lycoming value.

I noticed that several of the ECI manual torque settings are higher than Lycomings overhaul manual. I could only torque mine to about 160-180 in/lbs due to the castle nuts not lining up with the drilled bolt holes. I tried washers and various other castle nuts but nothing would work. I even tried to turn the stud but it was in there really tight. I was afraid of breaking the stud off so I left it and just torqued it down in that range. That's weird that the stud broke. Lycoming normal torque range for a 5/18-18 bolt is 204 in/lbs which is what I have used on all of the other engines. Thanks, for the update and I will compare settings from now on. Aden.

Here are some pics of the accessory case and stud.

I closed my case halves last night. My documented build is here.

I have installed all of the assy (except mags) and put the sump on. Now onto the cylinders. I will be putting these together from scratch. No cylinder kits here. All the valves have to be installed as well as the pistons. Lapping compound, ring pliers, and spring compressors oh my!!!

Started working on the cylinders today. Can be viewed at www.ecititankit.blogspot.com

Be advised that Lyc and ECI use different values for the ring gap with ECI being the smaller of the two. Lyc's nonimal value is at the top of ECI's tolerance. I don't recall specific numbers (it's been almost a year ago) but I had to download the .pdf from ECI for their dimension. The ECI rings fell right on nominal right out of the box. Just a bit of edge break needed at the gap faces.

Steve,
Thank you for the post. I will give them a shout tomorrow and find out what it needed. There is not much information on how the engine is suppose to go together. I have Superior and Lycoming manuals but it sounds like they are all a little different. I am learning a lot along the way. Thanks, again. Aden Rich.

If anyone in the seattle area needs help on one of these engines let me know.

That stud should not have broke at that torque setting. I have noticed that in aircraft applications bolt torques are alot lower than a standard SAE torque and no wonder saftey wire or cotter pins are required. In automotive apps I consistantly torque 5/16 -18 to 20 ft lbs or 240 in lbs. Those studs must have cut threads instead of rolled. I hope your rod bolts are of better quality.

Interestingly enough... it's not yet corrected.

They are still at a 5-9-08 revision.... I would have expected a quicker response to a major error...
