B's and C's have a 3/16" pipe that goes up in the filter.If it isn't there,your PSI will show little if any. I saw this in a posting maybe this past spring and an A.C. guy in Ind. confirmed it.Thanks to Roger V.

Varies with the tractor, condition, and as we found out recently the manufacturer of the oil filter ...! My two B's have a large difference - one runs slightly under the "N" in NORMAL, the other runs between the "R" and "M." This is a by-pass system - only a portion of the oil goes through the filter - so as long as you have *some* oil pressure you should be OK. My B with the "N" pressure is showing no problems at all related to oil pressure.

That was me with the oil filter!! I was just wondering what was normal. I have some type of aftermarket oil guage and it had shown a solid 10psi before the filter change and 5 after. It will be this weekend before I can put the old filter back on and see what happens.

The mains get oil presure not the rods the rods dip into the oil.

Actually, I think that the connecting rods are "oiled" by a "stream" or "spray" of oil from holes in the camshaft. There is a hole in the side of each connecting rod (on the camshaft side) to allow the oil to flow into the connecting rod bearing. Hope this helps, Tony

There was a fellow on one of the forums that actually measured the oil pressure settings for the standard "NORMAL" gauge. If I remember correctly, "N" was 3 psi, "O" was 6 psi, "R" was 9 psi and so forth. It's not exactly 3 psi for every letter, but it's close. I do remember the "N", "O", and "R" figures simply becuase I thought they were so low. When they explained this was a "bypass" system it helped. So one of my B's is running on 2 to 3 psi at the filter ....! You did get the notice from Sandy Lake Implement about the faulty filter design for the 0912 oil filter, didn't you? Something like if the filter has a rubber collar inside instead of the normal perforated metal/fabric the oil pressure is at least 20% less.
