How many of you are using gear pumps instead of diaphragm types and what filter element (micron) sizes are you using?

Now there's some empirical data. John, what was the lash on those big R&P's and what was the diameter of the rings?
I just had my first R&P failure in the past 16 years and it was while I was pouring on the coals 120 miles from home. It acted strangely as well because up to 38 mph (GPS) it was completely quiet. Above that was very noisy. There were two broken pinion teeth adjacent to each other. The regular noise variation told me the mesh area was moving as the speed went up, so perhaps the R&P got spread apart briefly by a broken tooth and the case got tweaked. When I put together another gear stack the diff carrier wouldn't preload with the same spacer/shim package. I've cleaned up another case for the rebuild because although I don't see any cracks, Like you said John, I don't want to see this anymore, so the oiling system is required as far as I'm concerned. I'm convinced if I had one already this might not have happened. |
