Is that the type of engine that you need to lubricate prior to cranking up? So: no oilsump and oil hitting your face?

And still our Dutch newspaper De Telegraaf refers to the PT-22 as 'sportvliegtuigje'. Grrr...

Interesting question...

Are you talking about "hand greasing the rocker arms"

If so, then it depends on whether an "R-55" or a newer "R-56" is fitted.

Talking to Ahern and Fried-
richsen about what to look for, you get most of the basic used-airplane advice; checking for corrosion, in-specting the logs for damage, etc. Both spent some time talking about the engine, since there are two different variations of the Kinner; the R-55 and the
R-56. The primary difference between them is that the R-55 has hand-greased rocker arms and a sleeve bearing for the front crankshaft bearing. The R-56 has pressure-oiled rocker arms and a ball bearing. Ahern prefers the R-55 and Friedrichsen the R-56 which in-dicates both engines will do the job.

•Adding external grease fittings so that the rocker covers didn’t have to be removed to grease the rocker arms, a frequent ritual with the Kinner R-55 engine.

At the other warbird extreme, a gentleman flew a Ryan PT-22 in from Texas. Since these little 160 horsepower beauties did not have the greatest cruise speed or fuel capacity, it took him 15 flying hours and 10 gas stops to make it to Oshkosh. What an adventure he must have had. He was to be envied. I didn’t ask him how much oil was consumed, but those Kinner engines, as do all radials, like to drink oil, hence an oil reservoir reckoned in gallons. His airplane had a Kinner R-55 engine, which meant that every so often he had to grease the rocker arms. The R-56 did not have that issue. As you can tell, I miss the one I used to fly.

The PT-22 "Recruit" was the most common version. Ryan produced 1,023
of this model. They were equipped with a Kinner R-540-1 (R-55) engine of 160 hp.

They were very similar to the PT-22 and NR-l airplanes, except there no gear fairings, the aileron counterbalance weights were on top of the wing, and the engine was the R-SS.

250 of these aircraft were field converted to Kinner R-S40-3 (R-56) engines of 160 hp, and were known as PT -22C models.
The R-S6 engine was thought to be more reliable, since it was equipped with pressure lubricated rockers. The R-SS rockers had to be lubricated manually.

The one in the pics looks like it has the R55 on it rather than the R56 which in my opinion does an inadequate job of lubricating the rockers on the top cylinders. I'd rather have the R55 and grease the rockers every so often, that 10 hours sounds like a good safe number.

Apparently this particular airframe (N53178 Serial Number 1859 ) is well documented on page 14 thru 18 http://members.eaavintage.org/wp-conten ... c-1998.pdf

“The Restoration of PT-22, SIN 1859
S/N 1859 was purchased from Kent McMakin of Rockton, IL on September 18, 1992 . I didn't start the restoration until March of 1994. It was a mostly complete airframe , but did not include an engine , propeller , and it was missing seats, some cowling pieces, instruments, miscellaneous fairings and many small components . While it was on its landing gear , most of the components had been stripped from it. Most control surfaces were damaged to some extent, requiring repairs . One wing had suffered extensive damage , having a cracked main spar and many damaged ribs . The other wing had been rebuilt , and was reportedly ready for some cover after some assembly. It still needed a thorough inspection. Overall, the aircraft and parts were in pretty poor condition.

From the start of the restoration process , it was decided that the PT-22 would be returned to very original condition.”

Further on the R-55 engine is mentioned.” The Kinner R-540-1 (R-55) engine of 160 hp dominates this view of the PT-22, and is topped off with a newly built Sensenich propeller, which duplicates the Sensenich prop originally installed.”

In order to prevent jumping to conclusions: al lot can go wrong. This aircraft was restored to a very original condition, and it is unlikely (however not impossible) that this has been mutilated in later years.
