We are about to fire a new 2056 and have tried to pump oil through the system prior to igniting. I have pulled the spark plugs and hooked up an oil pressure gauge. I can crank the starter for 30 seconds or so, but nothing registering on the gauge? More cranking?
Thanks |

Thanks Ideally you primed the oil pump with some light petroleum grease like Vasoline to help that pull suction quickly. If not don't panic. Postitive displacment gear pumps are self priming. Vasoline just helps expedite oil pump prime. Again, ideally a good Moly lube on the rods and cams. Moly isn't going to wear off at slow cranking speeds. No moly? Don't panic, long before there was Moly, mechanics have been using oil to pre-lube without harm. Moly is just nice insurance. More cranking is in order. There is a lot of volume to fill initially before you will develop pressure. 30 seconds at slow cranking with the starter speed isn't much by the time it works its way to the oil pump. Remember oil pump is driven off cam. Cam is driven off crank at 1/2 crank speed. Crank speed and rotation are but a small fraction of starter motor RPM's. @930cabman |
