Been lurking on this forum for several months (great info). Thought it time to post my first question. My 646's tired and worn pump is ready for replacement. I know once I replace it it will seem like a new/different tractor. My question is from my understanding the original pump was 0.73cu in, am I asking for trouble by replacing with a .84 as most of my lines are original and I don't want to start blowing lines. Looking at this one

or would I be better off going a little smaller than original and go with a .66 like this one

I do have a PTO on this tractor that I do use on a hydaulic roto-tiller that I made from a modified simplicity tiller
