Last picture is a measured shot ether system to aid in cold starting. 24 volt cranking is wired just like 12 volt, the only time there is a difference is when the charging system is 12 volt and 24 is only used for cranking. In most cases this is only used on on road vehicles.

I found the P&H engines listed in my "Diesel Engine Catalog" books as both Harnischfeger and Fairbanks-Morse in the volumes 19 (1954),20 (1955),22 (1958), and 24 (1959).The 6 cyl F-M was called Model 49B4 1/2 while the P&H was called Model 687c18. The earlier ones pictured used individual injection pumps actuated by the valve camshaft where the later used Roosa Master. Unique cylinder/head/piston assembly as the individual head was screwed on the cylinder and the piston was allowed to rotate in the cylinder-having no piston pin but a mushroom shaped connecting rod end that nested in a matching cavity in the piston. The F-M ads offered twin 4 and 6 cyl sets. the 6cyl naturally aspirated was rated 825 ft lbs @1300 RPM but for some reason none of the turbocharged units listed a max torque rating.

PS: The F-M ad mentioned approval and rating for fire pump service. That could explain the unusual cooling setup and possibly the letter F at the end of model number.

Does anyone know what the electrical objects are above the starter? There are two cylinders that look like coils and then two square boxes. They are only partially wired. I not sure how these fit in to the circuit.

Look like solenoids for the starter circuit. May have used two due to the 24 volt system and the high inrush current load.
I would just use a new single 24 volt solenoid wired to the starter terminal with a simple push to start button. If the existing coils/solenoids are 24 volt one of them may work but might not handle the load.

[Give the RoosaMaster number off the pump to a pump shop, they should be able to tell you the engine model. Maybe also timing specs.
The 1800 RPM is like a genset engine, maybe FB used the P&H engine for one of their electrical sets.]

I have looked up the number from the plate on this pump, in my old Roosa Master microfiche. The test plan below is the closest listed. It is for engine model 687C-18. All it tells us about timing is that it is timed to the line on the OD of the cam ring. This will be visible when the small plate on the side of the pump as shown in the photo is removed. When the engine is turned a timing mark etched on the weight retainer in the pump will show up. this mark should be in line with the groove in the cam ring when the engine is in the timing position. Look for an injection mark on the flywheel.
