Tried twice to send an amended letter to the net. Sorry. What I was trying to do was answer Brian Kraut's letter about meeting up for a Bbq. I told him there is no particular place that I can think of to hold this. I also told him that the first one to arrive should come back out to the camper registration building and we'll make up a note with a map so that all the rest of you can see it as you register to camp. A side note: to camp on the grounds... you must be either a member (in good standing) of the EAA, or the Florida air museum. Hope to see many of you there & enjoy some bbq or brats with you.

The past couple of days have been busy opening two engines. First of all I had a type 2 in the shed that I want to use for the case. The reason for this is that the type 2 case has the fuel pump. A down stream plan of mine may require the use of an engine driven pump. Now back to the engine from N110LR. I removed the cylinders and pistons while the engine was mounted to the aircraft. From that distance the cam and crank looked real good. As the engine got lighter and I could lift it, I removed it from the aircraft. After finding the correct metric 12 point star bit to remove the flywheel bolts, I proceeded to split the case and extract the crank and cam, for better inspection. On close inspection I could see ware patterns in the cam. The wear was slight and if I was not going to go for a different lift, I would have reused the cam and lifters, which show no visible signs of wear at all. The crank looks real good also. My current plan is to replace my 66mm crank, 96mm pistons and current cam with a 71mm crank, 103mm pistons, Force One bearing and a 490/275 cam. At this point I must express concern for any one flying an engine that they did not assemble, unless they are certain it was put together by a reputable person. After I removed the flywheel, I found that the case bolt that was supposed to be hidden behind the thing was in fact never installed. That somewhat explains the oil on the bottom of the case. Another strange thing about the assembly of this engine was that the nuts for the primary case bolts, the one's with the seals, were installed upside down. The neat thing about opening two engines at the same time is the side by side comparison that you can do. The type 2 case had an oil splash or windage tray in the bottom of the case. My type 4 did not. The other odd thing about my engine (type4) is that the front bearing (Number 4 main bearing, pulley end) was omitted completely. In place of the front bearing the prop hub lay in it's place. The hub is approximately the same diameter is the bearing shell. One must remember that this engine was assembled around the same time as the advent of the Force one bearing. For me the question comes to mind, what kind of wear is transmitted from the rotating bearing to the case. Did the builder intend for loads to be transmitted directly to the case?? It almost looks like it, except that there is not much indication of rotation on the prop hub. If I had the time I would use some plastic gauge to measure the space. If that is true, then the prop was completely unsupported through to the first journal. (any one with knowledge can jump in here) All and all this has been a day of discovery. Orma L.

Hey Orma - I have often marveled at your engine - has been doing well in 110LR for ages. Always figured it must be a really good one - now you find out that it is anything but. There is a lesson in there somewhere. I am keen to see the comment from the more informed members re the missing front bearing - surely this cannot be right.

It has been said many times that the only way to weaken a type 4 is to stroke the crank and that the 66mm was industructable. Perhaps my engine is proof. Yes Steven, in fact there was an oil seal which fit around the hub and sealed the space between the hub and the case. It sits in the case in much the same way as the Force One bearing. It makes me think that this hub was ment to be a hub and bearing all in one. Except instead of the bearing being allowed to accept the ware, the case is sacrificed. Perhaps the builder felt that the #3 main bearing was suffient and he did not feel that the shaft would ever flex enough to need the #4 for support. I wonder what would have happened at the aircrafts designed G load of +6 or -4. Orma L.

Anyone other than the Aviation mechanics and I would have been asking different questions. >From your observations there is no indication that the hub or the case has been doing any work, so #3 has been carrying the full load - where is the thrust washer /bearing on that engine? Given the cantilever distance from #3 to the prop - this says something I have been considering Steve Bennett's Great Plains VW prop shaft mount or a reduction drive as a means to relieve the auto engine of this load that it was not designed for - maybe I need not worry too much - now we see a Type 4 doing Ok with NO bearing. Other than G forces - there is another force at work every time you use the elevator. I heard of a Pitts 2A (IO-540) that had a crankshaft break clan off at the front bearing due to gyroscopic procession that was severe due to the sudden changes in direction.

The bearing halves thus resembling a collar/prop hub.?? Your experience has gotta be a first and I'm am quite amazed by it. How could it get oil and even if it did surely pressure would have been way down. Is it not more usual for this bearing in the VW to be purposely machined larger and longer to take the precession and end thrust.

I lifted out my crank and sat it inside the type 2 case, and sat the other crank still with the bearing installed into my type 4 case and the fit was nearly exact. For me that varified that the builder intended to omit that bearing. It looks like the prop hub was made to be the exact size that the case is. With the Force One bearing the case is opened to accept the bearing. Tomorrow I will go to the airport and get my mic and measure the prop hub diameter and compair it to the diameter of the #4 crank bearing on the type 2 crank. Orma L.

Apparently, using the aluminum case as the bearing with an oversize hub works to some degree. The biggest problem is that you have to change the whole crankcase when the bearing surface wears out. I am certainly not suggesting that anyone do this on their engine. I remembered hearing about an engine at one time that was made to use aluminum beraings so I did a search and found that it is common. I coppied this from an article I found on bearings: BEARING MATERIALS At the original equipment level, the use of aluminum main and rod bearings is growing for a variety of reasons. One is that aluminum bearings are less expensive to manufacturer than bimetal or trimetal copper/lead bearings. Switching to aluminum also gets rid of lead, which is an environmental concern for manufacturers. But there are many other reasons, too. "Federal-Mogul provides both copper/lead and aluminum bearings. But perceptions are changing with respect to aluminum versus copper/lead," said Federal-Mogul's Ron Thompson. "Most of the original equipment manufacturers are going to aluminum bearings, as are a growing number of rebuilders in the aftermarket. Many people are switching to aluminum because it provides improved durability and better control over tolerances.

I lifted out my crank and sat it inside the type 2 case, and sat the other crank still with the bearing installed into my type 4 case and the fit was nearly exact. For me that varified that the builder intended to omit that bearing. It looks like the prop hub was made to be the exact size that the case is. With the Force One bearing the case is opened to accept the bearing. Tomorrow I will go to the airport and get my mic and measure the prop hub diameter and compair it to the diameter of the #4 crank bearing on the type 2 crank. Orma L.

I also sanded through the outer primer to the smooth prime in a couple of places. My thought is that it is primer, so it is OK.. My plan is to paint the wings and ailerons separately to keep the paint out of the hinge. I am curious about what paint you are using.

I painted the hinge halves separately with the pin removed. I sprayed them lightly two coats and it was no problem to put them together. I also figured out a trick for greasing the hinge. After I attached the half to the aileron and wing I used the end of a small allen wrench to gob a tiny bit of grease in every section. If you just grease the pin and push it in you loose most of the grease half way in.

Sorry, that may not be true. I think that it depends on the type of paint used. I, don't know, but I would ask a paint supply if the paint system intended to be used is compatible with the two different primers.. An experienced painter would probably know also. I personally would rather spray the entire project uniformly just to make sure that the paint did not curdle and cause me to have to re-accomplish part of all of my work. Orma L.
