Perhaps Phil Ryalls will forgive me if I hijack his thread a bit further...
Up through 1975 Ford used a piston pump on their 2/3000s and 4000s without I PTO. Piston pumps produced ~4.4 gpm.
In 76 they gave the 26/3600s a hydraulic upgrade. Lift cover redesign, draft WITH position control, oil cooler and a gear pump with oil filter that produced almost double the flow @ ~8.5 gpm.
I am starting to see more folks ask if they can use the higher flow gear pumps on their pre 76 models.
The change is pretty simple - a bit of plumbing. Pump is a bolt-on swap.
My question: In general, are there any issues to consider if you double the flow in a system not designed for it?
