WD45 oil pressure

Welcome Guest, Log in or Register

Report to Moderator

The oil pressure in my WD45 was about 5 lbs. cold and dropped as soon as the engine warmed. I was advised to have the crank turned and install new bearings. This was done. Oil pump checks OK according to manual specks,and the relief valve seems to work OK, but now I have NO oil pressure. When the crank was installed I used plasti-gauge and shims to clearances in the manual. Any ideas?

Only JW was on the tight track. Cam bushings are more important than the crank clearance. The camshaft is the OIL GALLEY for the crank. ALWAYS replace the cam bushing. Next if the crank is guound corectly you use tthe std. shims and that should give the proper clearance. Next the oil folter has NOTHING to due with the oil preasure. The pipe that is pressed ino the filter bese and goes up through the center of the filter. THROW the stick away. This is a by-pass filter. The restrictor hole in the pipe only allows so much oil to go to the filter. Be sure the correct fitting are in the ends ot the lines that go to the gov and rocker arms. Take the T fitting out of the block and put the guage in there and start the engine to see if you have preasure. In fact you can take the plugs out and turn the eng over with the starter and you should get 20 lbs right there.Hope this helps.

Hi Rod,

Jim is correct is suggesting you check your oil filter. Here's my experience with the new style Wix/NAPA filter.

Hey Rod,

I appended some info to your original study. Basically, just adding a bit about Hastings filters. I can't post a link here, but it's our domain name and /filter

Hi Jim,

Great. The more information the better. I have added the Hastings LF405 to my list of acceptable filters:

AC C412
AGCO Allis 240912 (corrected version)
Baldwin T300M
Fleetguard LF571
Fram C159
Hastings LF405
NAPA 1101 (old design ONLY)
WIX 51101 (old design ONLY)

Presumably any of the above will work correctly without a noticeable loss in oil pressure. They have been provided by posters who are knowlegeable about the problem on this and "the other" AC board. I have not personally verified them all.

Cam bushings could be the problem. Happened on mine years ago when grandpa had it.

1st, check your oil filter. This has been a known issue for a bit. When you installed it, was there a wooden dowel you had to remove? WIX/NAPA has changed the style of their filters and now the oil flows too freely through the filter, and yields much less pressure where needed.
