The stress on the timing gears primarily comes when the pump is working against the relief valve (ie: you have run a hydraulic cylinder all the way to it's extreme and you're still holding the control valve forcing the pump into a high pressure situation). Those pressure reliefs are typically set up around 2000-2500psi (aftermarket valves like Cross) which is what will damage your gear train. Get a control valve with an adjustable pressure relief and set it on the low side (say 800psi or less. if you can live with 500-600psi, do it) then you will still be able to work, but without stressing those timing gears as much. And pay attention when you operate the hydraulics so you don't ever make the pump work against that relief valve. If you find you want more pressure, then pull the front cover and upgrade the gears on your terms (before they get shreded). An ounce of prevention ...
