Guest prs519 Posted April 13, 2011 Share Posted April 13, 2011 I have quite a few, apparently aftermarket, pistons of various sizes. They are embossed Ray Day. Can anyone tell me anything about such pistons? I have a wide variety of sizes, and would guess they were made in the 50s or earlier.Was Ray Day a well known company in its day?Thanks in advance,Perry in Idaho Link to comment Share on other sites More sharing options...
Guest Commodore Posted April 13, 2011 Share Posted April 13, 2011 Well, there is a Ray Day pistons catalog on Ebay right now.eBay (US) : 1932 DETROIT MICHIGAN RAY DAY PISTONS CATALOG (item 250402874310 end time Apr-26-11 19:21:43 ) Link to comment Share on other sites More sharing options...
Guest prs519 Posted April 13, 2011 Share Posted April 13, 2011 Thanks for the link Commodore! You also reminded me that the search engines do work, and I found this link of a picture of the ray day factory in Seattle:USC Digital Library - Interior view of the Ray Day Piston Factory in Seattle, Washington, 1930-1940, some of you guys will love this pic if you copy and paste to your browser. Amusing in a way. "Hey, dude, quit cuttin those skirts too wide". HO, "I will soon as you change that worn out drill bit". Seriously they probably more than made tolerance, it just strikes me as comical the way the factory looks.As for the ebay book, I would consider buying it, but I think the numbers on my pistons may apply to later pistons, and it would not therefore well apply! Thanks, Commodore, and I appreciate any other leads. Perry in Idaho Link to comment Share on other sites More sharing options...
Guest hefdog Posted July 30, 2013 Share Posted July 30, 2013 Here's a picture of a parts shop in L.A. in the 30's that has a Ray Day Piston sign in the background. Apparently these pistons were common place in parts stores across the country. Link to comment Share on other sites More sharing options...
Dave Henderson Posted August 2, 2013 Share Posted August 2, 2013 Ray Day pistons were standard equipment for the Cord 810 and 812. I was told that the skirts can be adjusted by turning embedded screws in the body that bear on the spars going from skirt to skirt. Anyone tried this?
