Message: [QUOTE="Wildman, post: 1290304, member: 18533"] The HPOP ball is one of many problems with the early style Rexroth pumps. When the check ball fails, you get a no start and low ICP. However, another issue is that the Rexroth pumps will fail in oil VOLUME, but not in PRESSURE. Therefore they'll build 500+ lbs of ICP during testing (blocked off), but they can't support the volume of oil that the injectors need to fire. Which makes it hard to diagnose if you're not familiar with early 6.0's. Later models got the Shepard pump, which was much more reliable overall. As far as trying to heat up the HPOP ball to get it out, that will ruin the pump. If you're worried about the ball popping out and you are looking to weld something to fix it, just weld the ball to the pump. Even though you risk damaging the pump by doing that (due to heat), it will certainly prevent the ball from popping out if it works. As far as rod bearings, I would never change main or rod bearings unless they were damaged. Bearings are not a wear and tear item; with proper maintenance and a high quality oil they should last indefinitely. Bearing wear only occurs due to oil breakdown, oil contamination, or mechanical failure. If the bearings are severely worn, that is a sign of other internal engine issues. [/QUOTE]
