I am a member of the Santa Clara Valley RR Society in Ventura County CA. We have recently been gifted this engine. The original diesel was replaced in the 80's with a similar Cummins engine.
I originally posted this in the railfan section and got some very informative replies, including a copy of the original manual. We are in the process of restoring this engine, hopefully for our Railfest in April, and I will be working on it.
I am posting this here to hopefully spread a wider net for more information to help with the restoration.
Thank You in advance.
