These kits from Real Gasket Corp replace problematic pushrod tubes of continental engine models: A-65, A-75, C-75/85/90/125/145, 0-200, 0-300 and GO-300. The installation does not require loosing or removal of the cylinder and converts it to an "independently serviceable" spring loaded pushrod tube system, similar to IO-470, IO-520, and IO-550 continental engines. It also allows access and service to the lifters.
Compressor Tool VSC-1 08-13615 is required except for gasket installation (not included in kit).
The kit is designed for easy installation and uses real gasket's FAA-PMA pushrod tube seals as used in the continental IO-470, IO-520 and IO-550 engines. For certified aircraft engines. This is a log entry, no special paperwork is required.
Kits include new push-rod tubes.
Great kit. Installed over the past few days as I did a full re-seal on my C-90. With this kit and a host of new gaskets, I am finally leak free (for now).
I have just installed these on 2 cylinders. Quick call to Chris at REAL Seals and he gave me some tips and tricks to make the installation go super smooth. ACS was quick to ship and they arrived in perfect condition!
Kit to stop leaks, excellent instructions, price was very good also. This kit sure beats Continental kit price
Ordered a complet set for my O-300-A. After disassembly of exhaust, intake manifold and rockers, removal of old tubes were cut with a saws-all. Old tubes came out with a little effort, but easily. READ THE INSTRUCTIONS CAREFULLY. I read them about 5 times before it really sank in. Once I got started, everything made sense. Do only one cylinder at a time. Kits are well made and complete. Must use their installation spring compressor. Consider it part of the cost of the job. All parts are FAA/PMA so only a log book entry required. Tubes work on all Continental engines A-65 through O-300 series (See AML). This is the answer to leaky OEM push rod tubes.
I would like a price on a complete engine kit for the a65 Continental ground power unit the engine I have is stamped with an E 237 I have researched it as far back as it being a 1961 unit it has one mag
Easy to install. Really makes a difference in the look. Remember to replace intake hoses.
Great kit but instead of saying youâll void warranty if using safety wire how about if you use zip ties and put any extra pressure on the tube to compress the spring you will absolutely ruin the seal that goes against the lifter cover every single time. Instead of saying if you use Continental spring compressor you void the warranty how about if used you will damage the seals and cause more leaks than if you had the old 1956 style seals. The lifter cover edges are sharp therefor they can easily cut into the rg 536410 seals. Taking it apart for the third time is always fun. Buy the tool as it will save days of down time. Instead of covering themselves from warranty claims how about a little explanation as why not to use safety wire, zip ties, or pushing them in place and ruining the seals??? I mean thereâs clearly no shortage of paper or ink for the page that says âdonât be a typical male, read the instructionsâ
This is a good kit to update the rod tubes on TCMs. Several people have commented on the instructions not being clear, or using extreme measures to remove the old tubes and install the new ones. Hire a quality A&P Technician to change these out! Remember, if youre not a certificated A&P, you cant change these yourself. Unless youre doing some shady work and if you are, this will seem like a nightmare to you! A good A&P can have these done in no time!
Be advised....order a spring compressor along with the tube kit. AC Spruce should mention that you need to buy a Real gaskets spring compressor to install the kit. If you use safety wire to compress the spring it will void the warranty. Ended up building my own compressor as I was in the middle of the job and did not want to wait for a compressor order to arrive. Job was straight forward and not difficult with the exception of the extra time require to build a spring compressor.
Pros: Cylinders do NOT need to come off Superior quality machine work. Cons: Oddly, requires the use of copper silicone to seal the rocker box side of the tube. Not too sure about this over the long haul. Semi-complicated instructions or more accurate to write, lack of detail. Should come with a spring compression clamp or at least offer one. Absolutely must have to install. Exhaust can stay on, intake tubes must come off (Cessna 150J). Must cut old pushrod tubes off with a saw (I used bolt cutters). Removing the old tubes can be tough. I used a vice grip and a hammer to remove. Some could be wiggled out. The job is not overly complicated, but the need to remove baffling may uncover some secondary repairs.
Yes, they are FAA Approved.
The STC paperwork is included in the package with the pushrod tube conversion kits for continentals.
Yes, this kit includes tubes, springs, and seals.
This can be used on the millennium cylinders IF they are the old style swage tube type.
For a 4 cylinder engine, you should order 08-04444 x qty 1.
The STC covers the install, no 337 would be required.
