Re: 1940 282 ci engine front seal

The same type seal was used in later engines so installation is briefly touched on in the 46-50 and 51-4 manual. There are a couple of decent photos in the engine section of the 46 manual. Page numbers are cut off in the scan but they are figure 32 and 33 in the section entitled Valves, Guides and Tappets which is almost at the halfway point of manual. Essentially an arbor was used to guide the seal over the sharp crankshaft end so as not to catch or damage the seal on anything. One thing they do call out is before tightening the chain cover use a feeler gauge to check all around the opening between cover and shaft. This is to more or less ensure the opening is centered around the crankshaft so the seal is sure to be running entirely against the machined surface.
