Question

What size EMD block does most locomotives have in it? A,B,C,D,E?

Answer 1

Hatch and Kirk in Seattle Washington bought most of the tooling for the 248/278A"s from EMD. I dealt with them when I was in the Navy.

Answer 2

Huh ?

EMD named series of engines, A was a Winton design, then came the 567 (as in 567 cubic inches per cylinder) in B, C and D series.  The 567 was made in 6, 8, V12 and V16 versions, and was introduced in the late 1930's.  The 645 was introduced in the mid '60s in 6, 8, V8, V12, V16 and V20 versions.  The 645 was E and F series.  Next came the 710 G series - still in production.  The A thru G are all two stroke diesel engines.  The H series is a four stroke diesel.

Many 567 engines have been rebuilt with 645 cylinder assemblies.

EMD series A thru G don't have really have engine blocks.  The crank case is a weldment, the cylinder assemblies are individually removeable, and field serviceable.

Oh, you'll like Preston Cook's article on maintaining historic diesels!

http://www.rypn.org/RyPN/articles/viewar...

He goes in depth about the various diesel types and how possible it is for operating museums to keep them operating.  He basically says parts can no longer be had for the A and B, but AC/BC conversions have some hope, and can even dip into E parts bins.

There are a lot more E locomotives still in freight service.
