Subject: LycomingEngines-List: Separating IO-540 Standard flange Crankcase
I have IO-540-C4B5 engine that needs to be split and rebuilt for my RV-10 b
uild project. I plan on machining new ST-122 pressure plates and 8 bolts/n
uts to separate the engine case since Lycoming does not provide this tool a
nymore.
Does anybody have the dimensions of the Lycoming pressure plates ST-122 and
the size of the bolts/nuts used to separate Lycoming crankcases. I unders
tand the ST-122-2 bolts thread onto the crankcase Thru-Studs, plates instal
led both sides of the case with nuts & washers added to the ST-122-2 bolts
to secure the plates. When the nuts are tightened down it causes the press
ure plates push against the other Thru-Studs that are up against the inside
of the pressure plates, causing the case halves to separate. Specifically
, what is O/D of the ST-122-2 bolts, the inside depth the bolts are threade
d to accept the Thru-Studs? Also, what size thread is on the outside of th
e bolts and nuts?
Any information regarding the ST-122 tool will be gratefully appreciated.
