Have owned this Jeep almost 40 years now, haven't driven at all for about 2 years now as it started to smoke a little. A complete makeover is in the works but seems like life gets in the way more often now as I get older. The grandson is going to do all the pretzel flexing on the project.

I've been working on the Jeep engine getting it ready to fire slowly but surely.
Today I ran across a problem with the oil pump install/orientation which I also discovered is a very common mistake.

While installing the distributor I could only after many attempts get it to drop in 180 out, so I started looking for the reason.
I then noticed the key on the bottom of the distributor shaft that mated to the oil pump was offset. I then searched the service manual and YouTube and discovered it was not only offset, but the keyways both the male key on the distributor and the female keyway on the oil pump actually had a slight taper to them so they only go one way.
It's very hard to see this taper with the naked eye but a caliper showed it to be true. Long story short I had to drop the oil pump (3 bolts) right behind the exhaust pipe in the third picture and re-clock the oil pump shaft 180. Distributor dropped in just like it sposed to was after that.

I'm glad these old motors were built to be easily repaired in the field!
