Radial Parts

[JSeward]

Hello everyone,

Just recently fell in love with the Cessna 195 and thought of a few questions.

The engine is obviously out of production so where do parts come from when overhauling the engine or replacing the engine?

Are there companies that make parts for them? I've been on several radial repair and overhaul websites and I did see a slideshow of a P & W cylinder forging being machined into a cylinder but on none of these websites does it say we make the parts for the engine.

What happens when all the parts run out for beautiful old engines many love?

There are plenty of Jacobs spare parts in the USA. Many engines were stored after WW II and it is still possible to buy a "new" engine and have a zero time engine. Jacobs Service Company did that for many years and now I believe Radial Engines ( Radial Engines (http://www.radialengines.com/) ) has continued that practice. Air Repair ( Air Repair Inc, radial engine overhaul, sensenich wood propellers, red line disk brakes, radialengines.com, radial engines ltd, jacobs overhaul, continental overhaul (http://www.airrepairinc.com/) ) also supports the Jake. Check out the International Cessna 195 Club ( Welcome (http://www.cessna195.org/) ) for lots of great information.

It was certainly still in production in the 90's in Payson, Arizona. I heard they subsequently moved to the east coast. As this engine is also used in the Wac YMF-5, that might be a good place to start looking.

The Jacobs (R-755 or L4MB) is available in several ratings - 245, 275, or 300 hp IIRC. Some are more favored for reliability and cost of operation. I think the 300 hp engine has higher-compression pistons.

There were also some pre-war civilian models, L5MB (830 cu. in.) and L6MB (915 cu. in.) The latter was 330 hp I believe.

From a maintenance viewpoint, the best thing about the 190/195 series is the swing-away engine mount. Servicing the accessory package would be VERY difficult without this feature.

It's strictly a matter of economics, I believe. There's nothing particularly hi-tech in the parts for the small radial engines such as Jacobs or Continental or Lycoming. With modern CNC (or :eek: 3D printing), and modern alloys, most parts could be newly-made and better than the original. That's not to say this is a cheap process, though.

Look up Currier's Flying Service on FB. They operate 2 195's. Roger Currier can probably answer any questions you may have.

Plenty of specialist manufacturers for pistons, piston pins, rods, valves etc that can make anything you want.
If you have something to use as a pattern, anything can be re cast as well.
Parts will never dry up, they'll just come from different sources and require more dollars to acquire.
