Replacement Cylinder

[Schinderhannes]

One of my cylinders (O-360 A1A) is cracked.  Gibson has only chromed cylinder in stock - any recommendation where to find a good overhauled cylinder or where to buy a new one.

A lot of people in my area get them from Zephyrs.

If you want to yellow tag a cylinder I'd recommend Faeth Aircraft in Sacramento. http://www.faethaircraft.com/. They have several train cars full of used cylinders.

 

For new I recommend Air Power in Texas. I've bought parts as well as my most recent engine from them. They are a Lycoming distributor so everything comes straight from the factory.

How much more is new vs. rebuilt? They are not the same thing.

A new Lycoming wide deck HO from Air Power is right at 2 AMU.   couple hundred less for this engine

o-360 cylinder is parallel valve. The angle valve cylinders are 2 grand but there a lot higher.

Here's one for 955$, and that's a new cylinder.

No 8,000 hour unit the head separates from,

no paint on the cylinder flange where the base nuts go (causes stud breakage),

no misaligned valve seats, which burn the valves at 500 hrs,

No used lycoming exhaust valves which will break off,

or the good one, from Gibson which has 7/16" valves in 1/2" valve guides. We just discovered 3 of those last month. Of course they refused to make it right. That cylinder was 800$

From what I've heard from mechanics and other pilots, a used or remanufactured cylinder from anything other than my own engine is a chance that I would not take to save $1000. 

 

I'm not sure of the compatibility, but one example was the cylinder that had 5000 hours on it through abusive management of a turbocharged engine. You simply don't know.

I have heard great things about Don George in Orlando. http://www.dongeorgeaircraft.com/cylinder.htm

Any concerns about mixing a Millennium cylinder with the stock cylinders and are these cylinders affected by the AD Superior products had a few years ago? 

[Wesley brown]

It's my opinion that if your engine is not new or if you don't buy all 4 cylinders new don't mix them up. Bottom end m

Beanings and the engine running loose on three cylinder verses one may reek havoc on your mains and bearings. I just did a top end on a 1200 hour 0-320 and had split up the work. One shop did all the re caroming on all four cylinders and new rings gapped and fitted. Another shop here in San Antonio did the valves and I had a little over 1600.00 in all four cylinders. All 8130 and I gained 500 fpm climb! And a cooler running engine.

The draw back is that it took me two months to get my cylinder finished this way! Well worth it to me I saved a tone of money.

Chuck ney in Oklahoma. Give him a shout! Great work and he should have some in stock. Overhauled.

The arrow across from us has 2 or 3 of the Ney cylinders break an exhaust valve on a set of rebuilt cylinders before 500 hrs.

Pacific Continental Engines did my cylinders. They might have some in stock. Chris P. runs the shop. Good family shop history. They purchase overseas engines where their countries have mandatory low time overhauls. I've mentioned it before here, but in Japan they have a mandatory 800hr retirement on some of their piston engines. I grabbed 4 cylinders off one of these 800hr engines. Sure better thank the 3900hr cylinders I was looking to overhaul.

By the way- I scrapped all 4 old cores for everyone's sake...

Cheers,

Sorry to hijack but is it worth it to have my IA pull my oil fouling cylinder and do a cam check and potentially rering or send the cylinder for overhaul? How many hours labor is thr R&R?

[MB65E]

It's at least a solid days worth of work. You could save some time for him if you removed the lower cowl, baffling around that cylinder, and exhaust system. Depending on what slip joints are effected you might need to remove the entire exhaust. A cylinder shop could then turn the cylinder around in a day or two. Unless your IA has all the cylinder hones, ring gap tools, ring compressors, the cylinder shop will be the better route.

Sounds like a lot of work. I thought people did this during prebuys so I thought maybe pulling the oily one out at annual would be reasonable.

You can only check half the cam. The first signs of failure are tiny pits at the nose of the cam and on the lifter face.

If the valves look good and the bore wear is acceptable, just hone it with a 320 flex hone and new rings and gaskets.

Jewell aviation (Sam) said he has lots of first run cylinders even the expensive double priced 200hp angular valve cylinders there on hand he could refurbish. He said sometimes he thinks it's waste when he takes a set of cylinders off a plane that's at tbo and the only problem was high oil consumption due to corrosion/pitting or broken ring and instead of fixing them the customer buys a whole new set. He said slot of cylinders only need a light hone, new exhaust valve, seat ground and a couple other small items.

My guess is he has some deals on used angular valves and will pretty much donate the cylinder if he can do the overhaul. Maybe $500 bucks to purchase the overhaul and he would throw the cylinder in. Can't remember the exact specifics but it was something like that.

[Wesley brown]

Good info I heard he did great work but never had any feedback! Thanks for the reply.

[Yetti]

On an 20F IO 360 A1A it is about 2 hours to pull the cylinder by a very experienced AP with a very novice helper

 

Based on what is involved, I would doubt that I would let someone pull a cylinder on a prebuy.    It puts the plane back into the "needs careful hours above an airport before it can be trusted again"   category

 

We will see how many hours to put it back together.

[Wesley brown]

Going together is much slower! Triple checking things and even finding corrections or repairs that needed. I have a rule for my planes if it is taken apart I actually take he time to allodine parts metal prep and detail or paint. When I did my cylinders on the grumman I pulled the whole firewall forward and painted prepped and replaced everything I could. The new owner had no appreciation of what he was buying. It was his first plane purchase.

Your should go back in four hours or so for the major parts another hour for cowling and run up. Use straight mineral oil for at least 35-50 hours for break in run it under 75% power full rich but no lower than 65% power until rings are seated. DO not lean under power until it gets a chance to seat and break in properly. CHT and oil temps are important during the break in.

[Yetti]

We won't be quite that fastidious of repainting everything, but touch up paint and replacing Adel clamps where the rubber is hard  and rubbing on the engine mount will be accomplished.  So far I think a pound of tie wraps has been removed.  Some aluminum polishing will also occur.  Who knows that loose wire hanging may be re attached to the CHT probe.   It is interesting to know what an "annual inspection" can "miss".   The good news is a trust worthy plane can be had with a little elbow grease.

[Wesley brown]

I hear you about annuals. My planes usually get attention all year long with major repairs before annual. The annuals are usually not that eventful. Either way you will pay one way or another. I just rather it be a gradual thing rather than one big hit .

I hope it all goes well with you!
