Title: Engine part 2
This week was lot of reading. Propeller and engine manuals, fuel servo and we'll just about every document I could find regarding torque values and I have finally turned the corner in becoming an engine mechanic. I've got most of my hose and clamps lined out and installed my alternator. Surprisingly the torque values for the bolts that go into the engine case are much higher than what we would use for nuts. For example the 5/16 bolt into the engine casing takes 17-19 ft-lbs which is over 209 inch-lbs. Normally when installing an AN5 bolt I would use between 100-140 in-lbs. And I like to be on the lighter side of this range so basically the torque values I am using on the engine are about twice what I am used to and I really don't want to over torque and break anything so this is something you triple check. In addition the engine overhaul manual warns that under torque bolts can wear quickly and cause damage as well so needless to say the correct values are very important. So this took me lots of time to read and get to know these manuals that came with the engine and the propeller (the alternator instructions say to use the torque values specified by the engine manufacturer). Next I ended up running some wires through the penetration point of my engine. It's really cool seeing it all set to come together. Still missing quite a few of my parts from the kit. My prop governor bracket, baffles, engine starter master solenoid, lots of things actually. It's a little frustrating as Van's waits until all the parts are in before they send you the rest, which I imagine is more efficient but for us builders it seems like a hassle to have to constantly skip steps and sometimes entire sections. But this is the current state of our world with all the demand and low supply chain issues we are facing. So, I guess I am onto working on the cowlings.
