Surprising that even after Rentschler et al left, the CW board still did not clean up their act. I read the article regarding the dubious inspectors/corruption at the R-3350 factory but I thought it w ...

The R-2600’s designer, Rudolph Daub, did the preliminary R-3350 design. However, he was reassigned to the ill-fated R-2160 Tornado project and the designers who took over the R-3350 project removed ...

NO. Free the screw by chasing the threads in the 'nut' or filing the threads on the screw with a thread file, then proceed with the procedure. The screw needs to be finger-loose in the tool.

I don't understand why you need more than one tool. Other books tell you to do what the Precision Engines video says, or give the option to do either. You don't need any particular accuracy because th ...

(Perhaps the inlet was designed for a higher airflow than the original engine was capable of supplying. just guessing.)

I concur with your guess. I have carefully read Bob Abernathy’s account an ...

I'm curious how much has changed in overhaul practices on engines from back in the day they came off the assembly line, to the present?
I'm sure there have been various service bulletins that have u ...

Unfortunately, there is little more information based on the contract and serial numbers. We know from the serial number that it was a FY 1941 Air Corps purchase, and that it was provided under the co ...

I've never heard anything good about the Sunbeam Arab either. I think its appearance in a marketing document should be taken at face value --- simply an attempt to sell a flawed product. News didn't t ...

From this, it appears that the document Pratt & Whitney Piston Reciprocating Engine Production is incorrect. It appears that the headings of the two columns were switched, as 75 R-2180-E Twin Wasp ...

Good morning,
It appears that the links to your photos are broken.
