I built my own engine oil primer/preluber tonight. I used a oil pump drive from a parts motor. A vacume pump or engine speed sensor from a 6.2 would also work. The drive I used was on a 95 engine. 97 is different.
The shaft of the drive is hollow so I took a 5/32 welding rod, stuck it in the hollow shaft to knock the cap off the drive. Then I took a 1 1/2 in #2 phillips screwgun bit and drove it in the hollow shaft[tight fit]. Then a put a couple of small tack welds on it to the shaft to keep it there good. Then I put a couple of flat washers on the top to deflect oil coming from the top shaft bearing/bushing.Then I slid a o-ring on the hex shaft of the bit for good measure. Then drilled a 5/16 hole in the cover where the centered dimple from driving it out was. Tapped the cover back on and off to the grinder. I put the new tool in a drill and spun it while grinding the teeth off the gear. I finished off the teeth on the top with a hand grinder. Cleaned it up and done.:thumbsup:
