I think the crankshaft collar part #26 is used to space the front bearing the pinion collar & would be made of hardened steel. It might be a light press fit so often it is not noticed on an engine overhaul.

That looks like a home made bushing probably used, as suggested, for shimming an over sized propeller hole. Looks like a piece of K&S brass tube to me.

No son..you are on mine

Sr most stoners would look at a pair of tweezers and go 'wow! what a flash set of roach clips' i like them.Over the years of use a castor like film appears on the finely serrated jaws,it's really sticky so it helps when you are trying to grip a carefully hidden short main needle extension if your engine is fully enclosed with very small cutouts.

Sounds like the film is from burning the joint really short!

Well, the truth is that I don't like trainers much but that isn't really what drove me to say Saitos would be a waste on trainers that I bought for a class being taught. I also bought Sig LT-40 kits for the students. The build quality left some airworthiness concerns too. Anyway, I still think new Saito 56s would have been exposing the engines to abuse. I had to then teach the builders to fly the things too. This was early in the program and I didn't know how well RealFlight would be for teaching basics before going to the field. It's kind of the same principle as seeing parents putting their 16 year olds in a new Lexus or BMW and turning them loose not the streets. I didn't expect the planes to have long, healthy lives.

I have torn down several Saito 100's, never seen anything like that. Took a old 120 down the other day and it has a sleeve like that keeps the cam gear in place

I crashed heaps of planes on realflight lucky for me the only sound profile they had in fourstroke was for a os 120,lucky me.Don't worry about young people abusing nice new saitos mate you should see what i've done to them.

Popey someone once said that it's ok to light an offending cigarette as long as you don't inhale.

Can someone tell me the difference between the Saito FA 150 and the Saito 150B?

Thanks,
Jim

Correct me if I am wrong but I believe the 150 and the 150 B are the same except for the jug. It is a larger with more cooling fin area

"B" case uses a different cam housing too. I wasn't aware that the FA-150B uses a different cylinder casting. The FA-180 does but that is probably due to the FG-30" gas" engines needing more cooling area.

Thanks for the pics---the engine I am looking at is an "A" version. Is there any real reason to prefer a "B" over the "A"?

I am considering buying a slightly used "A" version for a very good price but if the "B" version is lots better I will pass on the "A" version.

The only real advantage of the "B" version over the "A" is that the "A" version will leak oil around the shaft that the cam rotates on IF you use positive crankcase pressure for fuel delivery.

Makes sure that the shaft is well lubed

The shaft that penetrates to the outside on the "A" block cam housing is secured with a set screw & it doesn't rotate in the housing.

In the "B" block the cam housing keeps the shaft inside of the gasket seal between the case & cam housing

I got it just right. With the gasket surfaces on the B, cam box and cylinder, being on the same level it may have eliminated one machining step and enhanced strength.

I have a "B" FA-180 block & the cam housing gasket surface is not on the same level as the cylinder base. From my understanding, the "B" block is more rigid.

You're correct, they only look even in Horizon's pictures.
