I was reading another post and this came from it. Didn't want to high jack a thread. that would be a misalignment of the re-drive pushing back on the crankshaft. the flakes are from the 2 thrust bearings. they are there to keep the crankshaft in position. ![]() when the re-drive is mounted too close to the block it shoves the crank back against the thrust bearings and they wear pretty quickly. What is a redrive? I only found 1 thrust bearing in my motor when I took it apart, there should be 2? I'll take a picture of what I found that I think is the thrust bearing.

until someone with more experience on this engine can chime in, ill throw in my 2 cents. most engines only have one crankshaft thrust bearing. also cant think of anything that would really push the crank sideways too much... |

Glenn will chime in about the bearing setup. A bad torque converter can push hard enough on the crank to ruin the thrust. |

That is a thrust bearing. There is one on each side of the main bearing you took that one off. I have seen a worn crank move as much as 3/16" in other types of engines, but you should have very, very little if everything's set up right in yours. |

That's what I thought, it should have 2. I don't have my block at home it is at the machine shop. I'll have to check the block when I take the pistons there. Looks like on line they sell them in 2's. Are there just standard sizes? |
