[QUOTE="TBItoy, post: 656037, member: 1384"] I think mostly that is because the P pump is the oldest, most common, can be had in large displacement. I'd venture to say it is also the cheapest to rebuild (bushings, no bearing) On a play crawler (not a comp rig with big $ laying on the line) I'd be inclined to run 2 "normal" pumps in parallel (with check valves) to get your flow up. With a 3" ram, needing super high pressure won't be much of an issue. The electric over hydraulic has been hashed out here a couple times. It takes MEGA amps to put out decent pressure and flow numbers. Most electric over hydraulic setups available are higher pressure/lower flow than a steering pump, so you would need to use a smaller bore ram to get your steering speed up. Plus you'd need a big money Mechman Alternator to keep your charging system from shitting the bed when you are working the rear steer (think of it as running a winch) [/QUOTE]
