Got the engine swapped on the log splitter. Replaced the B&S with a 8hp Predator. Pretty easy, needed a mounting bracket for the pump(RuggedMade), a plate to mount the new motor(scrap ) and a longer hose. I think I like the pump higher off the ground, much easier to get to and less likely to catch a stump, even though it is more exposed. Motor seems to catch the first pull, even at 30, plenty of power. My thought is with the 8hp, if the pump goes(it is 15 years old) then a 16gpm pump may be an upgrade.
Of course, fix one thing more shows up. Flat tire, when I jacked it up found the bearings were bad, so new bearings and tubes in both tires. Hopefully good for another 15 years, then it may be someone else's problems.
