TSIO 360LB with (LTSIO03600KB limits)

[Invisibleman]

Does anyone know what "done to LTSIO03600KB limits" on a Continental TSIO-360-LB MO means? Googled, can't find.

I believe that the LTSIO is a Continental Turbocharged fuel injected engine that is left turning when viewed from the back (The L in the front).  They are usually used in some twin engine airplanes to eliminate the critical engine.  It is a O360 but not sure what the 0KB means.

This is a shot in the dark for you but I am pretty sure the L part is correct.  I seem to remember that years ago from my twin training.

I believe it’s the designations of continental 

L left hand

T turbo

S supercharged 

I fuel injection 

O horizontal opposed

0360 engine cubic in description 

K Constant speed prop

B brake horsepower 

kinda sure but not enough to bet on

I'm assuming the "MO" is designating it was actually a Major Overhaul and not just a tear down and repair back to specs (leaving anything that was close but still in spec).   

My plane when I bought it was listed as X hours since Major.  But going though the logs I only found a tear down and repair after a prop strike.  When I got the logs to the mechanic to look over he told me they did a really good job and they came up just short of a Major.  He couldn't figure out why they just didn't do it all.

Left engine Seneca 3.  They have an extra 0 in it.

Maybe some context on where this is from?  Is this a logbook entry?

There looks to be a couple typos, there should not be a (0) zero in front of 360 and there should not be an (0) zero after 360.  The K & L are model numbers, B stands for Big main bearings on the crankshaft/crank case, MO no idea.

DanB is mostly correct. Left Turbosupercharged Injected Opposed 360 cc. The KB is the engine model. The LB is the next model of the same engine, with some changes. If this was a major overhaul, I don't know why they would say "to KB limits." You should probably ask the shop/mechanic what they meant by that. I don't remember all the changes that were made by TCM from the KB to the LB, I think one of them was a larger throttle body. The LB runs cooler than the KB. If I had an LB (which I do) I would not want it reverted to a KB and it makes no sense that anyone would do that. I am going to guess that MO is someone's abbreviation for "major overhaul." I am going to guess that "to KB limits" just means that the original factory limits for internal dimensions such as crankshaft, bearings, etc. were used in the overhaul, but I would want to verify that the engine was not reverted to a KB. I surmise this is in an ad for an aircraft that is for sale and they are saying that the engine was overhauled. If so, the language used in advertising is often made up and not exactly accurate technical verbiage.

A Seneca II has a TSIO360EB, setup much like a 31 with GB or LB.  A Seneca III has a TSIO360KB, 220 HP - the extra HP comes with 2800rpm or so, and a 5 minute limitation.  I believe there are changes other than the RPM to get the extra HP.

There is / was an STC to add an intercooler and the KB engines to a Seneca II.

I don't think this is something you can do in the field to a Mooney?
