 Topic: AC - WD45 OIl pressure
Posted: 09 Nov 2010 at 8:26pm |
|
I have a WD45 that starts w/ decent oil pressure and after it "warns up" the pressure drops below the "N" on the gauge.
What is the recommended oil type/weight and filter for this tractor. Also I've read on this site that the tube/pipe in the oil filter needs to be a certain length.
I have added a washer to the oil pressure relief valve and there is little if any improvement.
Any suggestions will be appreciated.

Good oil pressure cold that goes away warm usually means worn bearings. Time for an overhaul...

My father's WD has the same problem as your 45, except Dad refuses to believe it's a problem. It still runs which to him means it must be fine. Can't say I didn't warn him!

Oil pressure will drop some as the engine warms up. It is normal. As long as it doesn't drop too low you will be fine.

What you might think of as low might actually be normal. According to the manual 12 pounds is normal. After I rebuilt mine I was expecting to see quite a bit more than that since 12 is about at the bottom of the gauge but I was relieved to find out that 12 is what it was supposed to be. You might hook a gauge up to it and see how many pounds you have before you tear it down. Could save you a few bucks!

Use 15-40 and a quart of lucas. Make sure tube is not stoped up or pushed down too far.

That works too, any thicker oil. The lucas really made a difference in one for me.

Stanley - I would check the guage. My 45 was showing "N" on the guage and when hot on a 95 degree day,the guage hardly registered. I replaced the guage with a 15# guage and have had no problems since. Cold is about 13# and on a 95 degree day its about 9-10#. - AL

Those "new" style filters should be out of the parts system by now. That's been more than a few years back if I remember correctly. I've been told that if the oil pressure gauge moves at all, they will live.

I think Baldwin makes filters for Hastings so they should be the same. I have a hasting one and it is the correct type of filter. Last time I bought a filter it was cheaper at TSC than advance.
