So my wife's breast pump started knocking and lost all compression. Turns out she spun a bearing and cracked the crank. Now me and the mad scientist(my neighbor Dan) gotta rip apart the block and replace the bearings she fried. Ask any pumper, any real pumper. It don't matter if you fill it by a liter or a mL, winning is winning.
Spun bearing
Cracked crank
Bearing re-pressed in Rod
Motor rebuilt with new JB Weld FORGED crank.
Good compression all around. Solid rebuild.
