I did some touch up polishing and made the case transfer size/area more equal from side to side. I tried to create the same margin relative to the base gasket. The floor of the reed cage area was uneven so I tried to level that out a bit too.
This is the original bottom end from my 2000 XC300. I learned the older engines have bigger crank bearings, 6306 C3 and the clutch side crank seal is bigger too, 30x52x7.
Putting in the clutch side crank seal in this engine was NO FUN! The older engine does not have an inner sleeve that the crank seal rides on. This seal rides directly on the crank which is no big deal but when installing from the outside with the bottom end assembled, the inner and outer seal edges come in contact at the same time. It boogered up 3 seals before I figured it out and got the 4th one in straight and clean. The first and 3 tries, the inner lip caught on the crank shaft lip and folded out. The 2nd try went in on an angle and snagged viton on the outer shell and wadded it up. While that was in I was afraid the seal would not be concentric and would wear unevenly or not seal correctly.
On the 4th try I created a spacer driver to use the crank nut to drive in the seal evenly. I also used some plastic film to create guide so the seal would slide onto the crankshaft without damaging the inner seal lip. Fun! Fun! Fun! 3 hrs later I got it finished.
The bottom end is together and I am waiting on some parts.
