Depending on how low it goes, and whether the engine shows other signs of wear (smoking exhaust, oil consumption, loss of power, etc.) you may be nearing rebuild time. But if it holds ok pressure and doesn't show too many other symptoms, you may can run it a good long while yet.
Even though my oil pressure was tolerable I wasn't comfortable with it. I went ahead and gathered up all the parts and gaskets after I determined which I needed (std. or oversized). I was lucky enough to only need standard sizes and it needed no machining. So I was able to replace the bearings and rings without splitting the tractor not to mention save the expense of shop labor. For me (and depending on your skills), it was well worth the effort to check it out before the engine was too far gone. The tractor has great oil pressure now, no smoke, and I think it's a little stronger as well. I took a bit of a gamble by not replacing the rear main seal (it wasn't leaking), however if you need a rear main seal then the tractor will need to be split.Romad50 wrote:oil pressure at first start-up but fades to almost nothing
