Today I started tearing down the engine I bought. It has only 150 flying hours but it has not been touched sinse 1986. Still there was no corrosion or rust at all. The owner has had the engine conserved and stored in a dry place all the time. It is an Danish 1600cc aeroconversion engine. So what I will do is to take it all apart, send the crankshaft to magnaflux inspection, have all the parts measured and ballanced, hace the case modified to fit 1834cc barrels and build it as an 1834cc engine.
I am going to visit the inventor club www.blekingeuppfinnare.se I am a member of to loan the hydraulic press there, so I can get the prop hub and camgear off the crankshaft.
I will use the Swedish EAA aprooved manual to build the engine.
This book is also very good.
I welded togheter an engine stand.
The case came apart quit easy.
The engine has not been used to much, the old markings are still there from 1983.
But the seals are old and dry.
The crankshaft is an original germal forged one. No rust at all.
The bearing dowels are nice and tight.
The rear (refeering to airplane mounting) bearing seat has no marks thatI can feel with my finger.
