The manual says Oil pump pressure setting - 101.5 PSI Min Eng. oil pressure, pil temp. 230 F (110 c) at 900 rpm 20.3 1800 rpm 31.9 2800rpm 43.5 There are actually 3 oil pressure control valves, they all have springs, and like you say it's hard to tell by looking if it's weak or not. I did...

Well I took all the oil pressure control valves apart and cleaned them, none were really dirty, in fact the internals of the engine are very clean as I saw it. I put new oil in and a new filter and started up going through the same routine as before. After the machine was warm the pressure was...

I stopped in at Bobcat today and they said to check the oil pressure regulating valve. Came home all ready to do that and realized I need a metric allen socket, the same set I borrowed to a co-worker today. I will keep you guys posted.

I just put a psi gage on with the sensor port and started the machine. I gave it 1/8 throttle until it warmed up a little as I always do, had 48psi. Went down to idle after it started running good and had 40. Went full throttle and had 60. Idled for 10 min and went full again and had 50. After...

Thanks for the reply J-Long. Would you just tee in a guage with the sensor or is there a plug somewhere that you know of?

I bought an 873G a few months back and found when I worked the machine hard and then let it idle, I would get a low oil pressure alarm/light. If I would increase the idle a little it would go off and I could go back to work. I decided to try a new psi sensor, now it seems to go on the same way...

Hi Everyone, Just purchased a used 873G. One of the side windows has pretty severe rust stains. Can anyone suggest has to remove the stains? Thanks!
