Alco 1945 ohv

Hi I’m restoring a 1945 Alco engine which I believe is very similar if not the same as a JAP series3?..does anyone have an image of the correct timing marks for this …the crank has an I mark for TDC and the cam cog has an O mark (if that helps)
Thanks in advance
Pete

Hello and welcome!

Some info on Alco/JAP model 3 here: http://www.riscy.uk/workshop/alco/alco.html

Thank you for that link.. it seems that’s about it on these Alco engines.
Sadly Nothing regarding the timing marks, these images are of the timing marks I can see.
The small cog is the crank and the larger cog is the cam with a O stamped on it ..I’m guessing they would line up?? Any info or help would be greatly appreciated

Back to basics then; with the crank at exactly TDC, and depending upon whichever stroke it is on, the valves should either be both closed or rocking.
