1972 Duster Build with my Daughter
The flash flare can be deceiving in the photos so don't use these as the reference. Looking at the part in person it is obvious... This is the side that goes in the housing first, not micro polished.
With a lot of oil on the seal the bushing slips right in. You can see the thin raised surface on the seal that rides on the micro surface.
The seal comes apart so make sure you see how it fits together. I pull it apart so I can get a good coat of oil on all surfaces.
Put a lot of oil on the shaft and it will slip right on. Be carful not to cut the shaft seal with the keyway.
I then flipped it over and installed the oil pump o-ring, lubed with oil.
Install the outer cog.
Drop in the shaft, making sure it is in the keyway at the bottom of the hole.
The drop in the inner cog.
Fill up the pockets with oil to pre prime the pump and bolt on the cover.
Now flip it over and fill up the crankcase making sure to slowly turn the crankshaft while pouring the oil on the difference bearing to get them will coated. The compressor holds about 8oz so it will take this entire bottle. When the system goes together another 8oz is spilt between the condenser and evaporator for a total of 16oz.
