Let me first start by appologizing for any dumb questions I might ask. But my experience with Lyc. engines over the years has been limited. Limitied to adding oil when needed in rental aircraft.
So let me explain what I'm doing and let me know if this is good, bad or overkill. First the engine - 0320-E2A 0 time SMOH in 1975.
Engine log entry: Aug. 7, 1975 tach time 4765 total engine time 2235.
Completed major overhaul this date as per Lyc. overhaul manual. Camshaft rebuilt by Lyc. Replaced all piston rings, exhaust valves (75068), valve keepers, main bearings , rod bearings, connecting rod nuts and bolts, #3 cylinder replaced with serviceable unit, crack welded and valve guides replaced on #4 cylinder by Chromelplate, Inc. Complied with Lyc. service instruction 1225B(main bearing dowel pins). Signed John W Langston A&P 585121314.
The engine is torn down and I will send the crankcase to Divco I guess they will tell me what I Need, the crank, cam , gears, rods, etc. will be sent to ????. (any suggestions here I'm flipping through Trade A Plane). Have cylinders sent to ????. Trade - A -Plane. Now once I have all my clean, polished, inspected and AD compliant parts back I find someone to put it back together for me . Any suggestions?
1. Logs say nothing about the crankcase - is sending the crankcase off routine for a major overhaul? Should I send out the sump/access. case?
2. "pieces back in the same place". Many parts like the lifters should not need any work. Do I have to worry abouth these parts returning to the same position?
Oh and by the way after removing all of my hydraulic units from my engine with a magnet I read on pg. 126 of Sky Ranch book " remove hydraulic units with Lyc. tool #64961 or a piece of wire NO MAGNETS PLEASE. What have I done!!!? Will this affect any performance or just my compass? Ok my brain is a sponge ready to absorb any suggestions. More questions to come
Thanks in advance.
