williamx5 is on a distinguished road
Thanks everyone!! You all really are the best!!

This is the latest and greatest!! I got this in the mail the other day and figured I would share... I got this instead of the other, more complicated and more expensive version... I can't wait until I am ready to use this!!



It doesn't really fit in the foam, but I made it work...





I marked the rods so they go back where they came from! Oddly, the right and left bank connecting rods were made a day apart...





Didn't take any pictures during the crank pull... Here is the block with the crank finally out...



The caps are numbered 1 thru 5 from front to rear... The front main bearing was the only one that I didn't think looked perfect...



The rest were not bad at all!!



#3



#4



#5 and the only one with thrust bearings...



Everything was glossy and smooth on the crank... May still take it to the machine shop, along with the block to get their thumbs up before re-assembly!!









And the internals...



The connecting rods... I'm guessing the letters on them mean the bearings needed... I haven't done the research yet on the rods, but I do know the code on the block indicate what main bearings are needed... Get to that in a few!

These are cyl 5 thru 8... 5=JD, 6=IF, 7=IH, 8=IP...



And here is a shot of the main caps number... Hard to see though... This one is #5 and the next is #3...





And the four bolt main caps... After you torque the main bolts, you snug these spacers to something like 16 ft/lbs, then torque the outer bolts...





Here is the code for the main cap bearings... All mine are the same... "G" means Green... It doesn't mean they are "Good To Go"... It is a color code BMW uses... Hard to see, but they are "GGGGG" in the upper right hand corner...



This is the section on the connecting rods... This is the connecting rod bolt... Odd!!



This is how all the rod bearings looked... Not scored, but normal wear...





The cylinders... Think this is cyl #1... Dirty, but cleaned up nicely after wiping them out with just a clean cloth... No imperfections noted when running my fingers over it...





I pulled one of the damaged pistons off the connecting rod... I pulled the rings out and put them in the cylinder to see how they were gapped from the factory... Not bad at all!!



Oh, the rings different... The top ring is thinner than the second... The oil ring is almost the same thickness as the second compression ring... There is engraving on the top of the piston... 91,986 and 25H2 on one side... An arrow pointing forward on the other side... I'm guessing 91.986 is the diameter in millimeters...

Well, that is all I have for now... It's Easter!! Go have lots of food and enjoy the day!!!

Cheers for now!!!!
