Hello all,
it has been some time due to health and family issues, but now retired and most projects sort of up to date and now wanting to get my 8N working again so I can participate in my local tractor club who drives in parades.
Summary of what I did:
a. had good oil pressure when purchased about 8 years ago. That continued as I used it around the yard, but then it sat.
b. reading on forums, I successfully did that prime the oil pump through the oil relief valve in front of the engine.
c. Now my memory gets fuzzy. Since I got the pressure back, I changed the oil since I did not know when the previous owned did it. What I don't recall is if I did it cold or after I ran the engine to warm it up. I changed the oil filter too and I cleaned the air filter with new oil in it. There was a screen at the drain plug and it was clean. I felt for the pick up tube and it was tight or snug, no slop to it. I then drove it into the barn and it sat. I started it periodically throughout the next several months but then it sat.
d. I repeated the "prime the pump" routine, but this time not successful.
So before I try that prime the pump routine again, I have a few questions.
1. my Amish tractor repair shop said he would not put in that heavy weight into the engine. This worked for me (once) and others on the forum in the past, so is that little bit bad or only do it moderately? Could that have clogged any of the oil ports throughout the flow system?
2. I read where someone stretched the spring that is in the oil relief valve. how do I know if I should do that or not?
3. I disconnected the tube by the pressure gauge and nothing was coming out there. I followed that tube downward and disconnected it there and no oil was there either.
4. Any advantage to changing the oil again now?
5. How long can I safely run the engine to see if I get pressure?
6. JMOR, back in sept 2009 shared a great picture of the engine oil flow. In that picture, in the upper right, was a green garden sprayer, but I did not see an explanation as to what I could do with that? Was it to try and force pressure through the tubes to try and clear any clogs?
7. My last question is about trying to clear the flow tubes, if that is at all possible, how do you do that and at what spots do I enter that air pressure?
I hate to drop the oil pan, I know that is last resort. Maybe it sounds scarier that it is.
Thank you. Appreciate any insights.
