I went over to the farm this past Sunday to do some mowing. I took out the 1979 MF 275 because it hadn't been used much lately since we got the new Kubota. I checked it over and greased it before I took it out. The oil was a little below the full mark but not too bad, probably less than a pint. The oil pressure gauge was running a little lower than I remember it (it used to run in the middle of the green) but it was still just in the green at PTO speed (1700 rpm) and went back towards the middle of the green when at idle. I made a mental note to top up the oil before using it again. Well, I was over at the farm again today and My S-I-L was off on the Kubota so I took out the old MF 275. I topped up the oil to full and this time the oil pressure was on the green/low borderline at idle and dropped into the yellow when at PTO speed.
The oil and filter were both changed last year and probably have less than 30 hours on them but the tractor has been sitting around for about 5 months. The oil still looks relatively clean on the dipstick.
I don't want to ruin the engine by continuing to run it so I'm looking for guidance as to the possible cause of the low pressure reading or things to try before I start ripping it apart or hauling it off the be fixed. /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif
Any help or suggestions would be greatly appreciated. Thanks in advance.
