SH1 Build Questions.....HELP !

[CLS447]

Yesterday I got back together with my friend ,Andy Peters, at his new hangar & home for his SH1 build.

He hasn't done much since the last time we were together, but he did get some upgrade parts.

1. What are you supposed to do with the alignment pins on the bellhousing of the Subaru 2.5 ? We did something that we did not see in the drawings or plans & I want to see if it was the right thing.

2. There are 3 bolts that hold the "arms" for the prerotator lower unit to the PSRU & engine. What bolt is used to go through the engine? Must the metric threads be drilled out , so a long bolt can be slid through ?

Some pics of these areas would probably be more helpful than the drawing that we have !!!!

[CLS447]

I pulled up my old thread also.

[MichaelBurton]

I don't have my camera today so no pictures but there is a long bolt that goe through one of the holes and it needs to be drilled out. There are two other holes that need to be tapped. If you take a picture of the area you have questions about I may be able to add comments to help. I have built or helped build 4 SH gyros and have two in the hanger for reference.

[CLS447]

Thanks Mike ! We may need you for a great reference source.

We have tapped the 2 holes that held the alignment dowels. We were in doubt about the other hole , Thanks !

Mike, was just trying to get some information for a friend that has a Subaru 2.5 engine on his RAF, he is thinking about taking off the oil cooler, and my question, is it really needed on the 2.5 engine, or possibly this is a dumb question.

Thanks

Wayne- My 2.5 on my SparrowHawk ran fine without an oil cooler. Stan

[lanichol]

That may depend on your radiator.

While flying on a 105 degree day at Buckeye in a Sparrowhawk we landed as things were starting to get warm at mid morning. They have oil coolers. AZ is one hot state in the summer.

3 days earlier I flew with KennyJ on a 105 degree day (at sea level) with no problem. Ken has a large radiator and no oil cooler. We may have had some cooling at flight elevation from the Ocean 10 miles away.

[WHUBBS]

Thanks, Stan and Larry, my friend would like to remove the oil cooler, although he has not flown his machine yet, he is located in western part of N.C., i know Stans S/H and it had run here in middle Tenn. and the new owner reported to me that it was doing well, when he was flying it. The same person that bought Stans machine, has also now purchased a Zeon.

[WHUBBS]

Sorry, i can't even SPEAL, my fingers are dumb, i ment Xenon instead of Zeon.

Stan,

You say your engine ran fine ?

Could you elaborate, ?

What was the engine supposed to do ?

What was the engine oil temperature average and max out on the hottest day you flew ?

Do you know why an engine needs an oil cooler ?

Jonathan,

In all seriousness; I would not mind a detailed tutorial if you have the time.

Regards,

Jim,

I am not trying to start something but I have a problem with folks that say, ahh, you don't need it , I never had one... and do not have the foggiest notion what it does, why you needed one and how close they may have come to having a problem. Subaru is one tough engine but if you have been following the evolution of the engine you know that they now come stock from the factory with one.

I will put together something worth reading.

Stan, I am sorry that Jonathan has decided to start picking on you too. Have to admit it though.... Feels good knowing I am not alone in the Automans crosshairs, but hate that he has moved on to being a dick to you, as you don't deserve it, I probably do deserve at least a little bit of it . :angel:

Hopefully he will learn how to better communicate one day :argue:, as he isn't really a bad guy deep down inside. :noidea:

[StanFoster]

Jonathon- You sit there like a vulture on a limb.... Once again...nothing you can say will get a response out of me in this thread.

Stick it.................

Stan, you built and flew a SPH.

I have asked you a few questions because you sounded off like you know.

Are you man enough to answer them or is that too much for you ?

Wow!
Buddy, lighten up!!!
"All he said was it ran fine".

That's hardly expert advice offered now is it, It ran fine. He never offered or tried to explain how an engine can benefit from using an oil cooler now did he?

I know Stan, Stan is a friend of mine and we both don't have time for fighting with our fellow man and we expel negatively by ignoring it.


So buddy why try and look for or start a fight? Life can be a party if you let it be.....

Why not just help and explain the benefits for those who don't know.

your friend John

Ron- Hey...dont worry about me....its not like I am over in the corner bawling for my buttermilk! :)

I guess if someone wants to run walmart oil then a cooler would help and also help to add weight and other problem sources such as hose or clamp failure.
Running a good synthetic oil in todays engines without a cooler is fine!
It wont break down or oxidize with normal use even in hot weather.
After all the engine was designed to be water cooled and the water does cool the oil.:yo:

[WHUBBS]

Just wanted to say i apologize, for asking this question, for a friend of mine, but at the same time i want to thank, Stan, and all the others that have assisted me with my question. we have lots of knowledgeable folks on this forum, and i have had lots of help, when i needed it, i will inform my friend with the 2.5 engine, of your comments, and let him make up his mind as to the direction that he should go.

Thanks

Wayne

Look,

Since there are some crybabies here, I will stick to the question asker.

The RAF with the oil cooler issue. Why does he want to remove it ?

What is the oil temp during the winter ? . summer ?

You can install and oil cooler thermostat that will regulate the temperature.

[StanFoster]

Wayne- While I was building my SparrowHawk, I asked the company if thet recommended an oil cooler. I was told that yes, in places like Buckeye,Arizona, they recommended installing one., but I should be fine without one. i never had any high oil temp readouts during my 245 flight hours, even though I was having my water temp spikes that persisted over a year until I discovered it was nothing but a mal matched radiator cap /fill neck combo. So even with these temp spikes in my water, my oil temps were fine. Back to my first answer, She flew fine! Stan

Here's some information that may help you in making your decision:

In general engines have two different cooling needs. The top of the engine: the area around each cylinder in the engine block, the combustion chamber areas in the cylinder heads and the intake manifold, dispel heat through the engine's radiator coolant system. (2) The rest of the engine: the crankshaft, bearings, camshaft, lifters, connecting rods and pistons are only cooled by engine oil. Rotary engines depend upon oil cooling for 40-50% of its engine cooling

The average engine ideal operating range for engine oil is 180°F through 200°F. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 200°F and 220°F with oil temperature ranges between 20°F and 75°F HOTTER. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 220°F rapidly loses its ability to lubricate and cool causing accelerated fatigue and premature component failure.

Benefits:
* Longer engine life and engine performance
* Reduced heat load on engine and radiator
* Increased oil system capacity

Adding an intercooler to the intake and even more benefits accrue in both performance and longevity to any engine.

[automan1223]

Stan,

Curious why you are not publishing any real numbers. ?

What WAS your minimum, average, and highest oil temperatures ?

Just think of all the hundreds if not thousands of posts you could have saved yourself.

"It ran fine" Theory on the forum according to Stan ..............

News: Its fine out there
Off topic: Looking good
Adm report: Was almost a problem but we deleted em,
Events: Even better than last time.
Welcome Mat: All sunshine and lollipops in here
Photos : They look fine
Flying videos: They look fine too.
General: All good here
PRA Discussion: Lets talk about somethin else
Piloting Technique / Accidents : Some busted stuff but all is well
Training: Almost a problem but looking good
Builders Corner: Don't worry about it, all is well.

:rapture:

Jonathan, Buddy!

What are you thinking?

Stan told us all he's not going to respond.

It will have to remain a one sided fight!

My bet; there will be no FURTHER responses to you on the subject, period.

So no more continuing your fight, the water cap simply wasn’t tight!
Stan meant what he said, and said what he meant, so no more responding to you on this thread. On this subject you might as well be dead!


Stan's radiator cap problem has nothing to do with a normal setup. What good would numbers do anyone who has a normal radiator without any leaks?

[robertstodaro]

Hey! I run wal-mart oil in my rotax 618.. no sticky rav valves. "it runs fine"

[gyromike]

Jonathan,

What is your problem?

If Stan doesn't want to answer you, pick up the phone and call him.

[automan1223]

You guys need to take a pill or something.

Nothing in my post here has said anything about Stans radiator / headgasket / overheating problem. (even though I know he ignored me when I called him on it in a completely unrelated post. )

the question was regarding OIL TEMPERATURE.

I AM NOT TRYING TO START OR STOP SOMETHING I am not even talking about.

Take the ear wax out already.

Stan says his engine ran fine then says he did not need an oil cooler and then I asked him what his temps were.

Stan flew in much northern latitudes than Buckeye AZ.

Since I do not live in Buckeye or Chicago, It would be interesting to find out where you need one vs not.

Of course a scientific approach to something that does not involve a......

Forget it. I could care less.

Instead he is crying in the corner in his buttermilk. :noidea: where is anyones sense of humor ????

[robertstodaro]

I wish I was psychic. Then I would know what the temps were. Guess I'll just take a pill.

[okikuma]

Anyone have any Haloperidol? LOL

[gyromike]

It's not what you ask Jonathan, it's how you ask it.
You act like you're interrogating someone as though they are deliberately hiding information from you. Not everything is a conspiracy.

Now that was a funny post!:first:

Hello John, I have been wondering about that proclamation.

I was trying to stay clear of the paroxysm so I postponed my query.

What would the benefits of adding an intercooler to a normally aspirated engine be?

Thank you, Vance

Thank you, VanceYou are correct I should have added to a turbo charged engine. I did think of it after I posted but was to busy to edit!
