1456 Oil Pressure Problem

Howdy, looks like I found the right place. Anyway I have a Farmall 1456. I had been sitting for a few years, and I got it. Had a broken cam gear, tore the the engine down fixed it. Got it going but I can't seem to get any oil pressure to show up on a test guage. I know it is pumping oil because it filled the filters up just cranking it, and I found an oil leak. I pulled the stock tellight out, and if you crank it up it will pour oil out there, but I can't get anything to show on my guage or on the stock light. Is that not a pressure port? Or do I have problems.

Any help or info on this tractor would be greatly appreciated. Thanks BD

OK I know I am in the right port now. But still with new oil and filters, no oil press. I need this tractor ASAP! I tried blowing out the ports but still nothing. What is up???

This engine and oil pump system is very reliable, they leak at every joint but still not enough to starve engine of oil, easiest place to start is take oil pump off side of engine, take housing apart, there is a relief calve cartridge inside, perhaps its stuck or chip lodged inside, also another valve on rear lower header that supports the oil cooler right next to oil pump, maybe same fault, if nothing else find a used pump from any DT361-1206 or DT407-1256-1456-915D(early) and try it. If this dont fix it assuming guage is correct I dont know what else it could be.

Had the same problem with the one I bought from the dealer . It had a lot of build up of sludge in the lines / ports. Took air hose and blew them out , also needed a new guage - too pluged up. Hopes this helps.

You should be at a check port that is suitable for a test master guage, plug it in (or screw it in) and start engine and run at low speed assuming you have correct oil level in pan, if it seems to have pressure at lower speed then try medium speed and so on.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership, ... [Read Article]
