Hey yall,
I’m looking for some opinions on this. I have a 1973 Ford 4000 SU farm tractor with the 172 ci, 3 cylinder diesel. Over the summer I noticed that the oil pressure gauge was showing a decrease in pressure. Unfortunatly I cannot remember for sure what the pressure was prior but I think it was about 50psi but now was down to about 35 psi. I decided to replace the pump, pressure gauge, new oil and filter.
I installed a new pump #FDS3542 from Steiner Tractor
New filter, Motorcraft # FL1A
6 quarts Rotella 15w40 and 1 quart Lucas oil heavy duty diesel stabilizer.
The new Bosch pressure gauge read 70psi at start up and dropped off to 65 or so once warm. I used the tractor to mow several times since for about an hour each time. The ambient air temperature each time was in the high 40’s or low 50’s and the oil pressure remained the same as described ( 65 – 70).
Today was downright balmy. Mid 50’s and I started the tractor to move a boat. I was focused on the volt meter at start up and not the oil pressure but did notice when the oil pressure dropped off suddenly to about 35psi. I got off the tractor to look around and saw oil blowing out of the base of the filter. I shut the tractor down and upon inspection found the base of the filter so distorted that the o ring was blown out. It took 6 quarts to fill back up and a new filter. I started the tractor again and the gauge pegged to 100 psi then blew the filter again.
What the bleep!
