Please refer to TCDS A6CE for details.

My TYPO Dave

It is actually a IO360CB6B. I forgot the C

FWIW, the CB6B has the 200 additional hours so TBO is 1700 and the real difference is the Main and Rod journals are larger than the previous C only model with out the B. 6B designates the accessories as a 24V 38 amp Alt and the Tach p/u on the mag

Well, yesterday was the last flight in my Skymaster with the original front engine from 1968. 47 years ago Continental Motors delivered this engine to Cessna in Wichita. Since then there was one major overhaul in 1980, before I started flying it, that dad had a shop do. We had to change a couple cylinders, a starter or two, throttle body and fuel control but other than that, maybe a vacuum pump or two, it's been amazing power plant. I can't complain as it has 2200 hours on it since the overhaul in 1980. Still operates good, has good compressions but is starting to leak some oil out the cylinder drains as the valve guides are very worn. I have very limited knowledge on the overhaul in 1980 so I am not even sure it has a VAR crankshaft. I am assuming it does but the log entry is lacking in that detail.

I am exchanging it for a FACTORY ZERO time reman from Continental. It is a IO360CB6B which has larger main journals and ups the TBO to 1700 hours from 1500. Continental has been great to work with and has gone out of their way to make this as transparent as possible. My hat is off to them so far, we will see how the rest of the program progresses. I am doing most of the work myself under the direction of my A&P at Griswold Aviation in Marshall, MI. Started today and have about 60% of the dis-assembly complete. Hope to see a new crate show up in 2-3 weeks.

I am having the propeller governor overhauled and the hydraulic pump as I don't think they have been done or at least for a long time. Of course new engine mounts and lots of cleaning, tidy up of wires. Anything else that you can think I should address let me know.

List price for the engine is $50,492.00 and with the core credit of $14,500.00 it makes the bottom line $35,992.00. It's a big hit but I think in my case I am better off with the reman for several reasons, especially not knowing if I have a VAR crank.

I'll post some results as it happens

Wow, quite a story Herb with the original engine. This is a very interesting thread to me as my factory reman engines from 1988 are at about 1490 hours each. I don't have any reason at the moment to overhaul but nevertheless it will be interesting to hear the final numbers. Where's the rear engine at in it's life cycle? Just curious.

Good Luck,

Ed

I don't think that the VAR cranks came into existence till sometime in the 90's. TCM has a special right now where you wont be penalized if your core has a non-VAR crank.

Thanks Dave, I was assured by TCM that I would receive my full core value.
Ed, rear engine is about 1000 hours

Congratulations Herb
You might consider a lightweight starter if that is an option.
Also if you are thinking of GAMI's now might be the time as you may be able to send the GAMI's to the company and save the cost of the original injectors on that engine.
Just a thought...

[hharney]

Thanks Jim

Did GAMI's several years ago so I will keep those and send the new TCM injectors back with the core

I really don't see the advantage of the lightweight starter. They really turn a lot faster and do not have the duty cycle like the originals, only my opinion

Cheers
