Subtle Differences


| April 2005


Examples of casting numbers on Plessisville Foundry engines.

As reported in the March issue, I have acquired a "look-alike" Hercules manufactured at the Plessisville Foundry in Plessisville, Quebec, Canada, in 1931.

Although the engines built at Plessisville look very similar to those built by Hercules at Evansville, Ind., there are subtle differences.

For instance, many of the Plessisville castings had numbers cast into them (Photos 1, 2 and 3), while those from Hercules seldom did. Perhaps it was a difference in what the foundry people saw fit to include in the casting.



Photo 4 shows another difference, namely, a groove on the governor bracket behind the detent blade; engines built by Hercules are smooth in that area, with no groove.

Photo 5 shows the fuel mixer on the Plessisville engine, which not only has a casting number, but also a boss on either side (this shot only shows one side). It would appear the foundry core mold required a wire support going through the two bosses to keep the mixer in place during the casting process.
