SC oil pressure problem (continued)

Now I have a new problem. I removed the oil pan on my 54' SC and unscrewed the barrel nut which holds the pressure relief spring and plunger in place. The spring was gummed up and stuck to the barrel and the plunger would not move. I then used a small hammer and one of the rear-oil-pan bolts to tap on the back side of the plunger and it moved in about 1/2"! I then tried to pull it back out, thinking that I had freed it up, but it would not move with the suction force that I could apply with my pinky finger. I thought that the presure of the pump would be sure to free it and that it would probably stick out again. This would give me another chance to work it free. Unfortunately this did not happen. After putting things back together and adding oil, I presssed the starter button and it started right up. I then glanced at the oil pressure gauge and immediatly ran over to the other side of the tractor and grounded the magneto. The Gauge was pegged at over 60 psi. I then tried to hand crank the tractor with the magneto grounded, while having a friend watch the gauge to see if there was oil pressure, but there was none. I did notice that the tractor was somewhat harder to hand crank. I next had my friend stand at the magneto so that he could ground it if the oil pressure spiked again. I stood at the starter button and started the tractor. The gauge immediatly jumped back up above 60 psi. Does anyone know of a good way to remove a stuck plunger that will not come unstuck with oil pressure? I don't want to run the tractor in this condition, since I am worried that it will shear a key, crack a casting, or damage my nice original rochester gauge. I guess that the next step will be to remove the oil pump. Suggestions and comments are very welcome.

When you had the pan off you should have pulled the pump out and put air to the outlet to blow the relief valve out and cleaned it up!!

We always used a tapered wooden dowel. Taper it on the grinder and then tap it into the valve, twist and wiggle and pull and it will come out. then clean it up and put it back. hth

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are ... [Read Article]
