From what I can tell everything I can buy has some sort of coating on it. What are you thinking could be the problem? I ground everything down nice and smooth to bare metal and I'm waiting on the Cicio washers to put it back together to see what's up. I also welded up the crank and used a jig to machine it all nice and flat. Looks brand new. But if I need a non coated flywheel I can replace it. But again from what I'm seeing everything is either painted or anodized.this could be the problem.
It's currently bare metal but I haven't put it back together yet. Waiting on the washers. After I throw it back together I'll know if it's something engine related or if it was just the flywheel. It's just weird to have any issues from slowing down quickly. I've never had that before.imho the force is being transferred from bare metal to metal, not the studs transfer the force. so if there is paint on it i might be the cause. but u said the area is bare metal
That would be good news. Since I removed the flywheel and bellhousing I removed all of the coating on the back of the flywheel, welded in the low spots in the back of the crankshaft, machined everything nice and flat and am currently waiting on the cicio spacer to throw it all back together. If it was that was what was making all the noise, the noise should be gone or at the very least change in how it sounds after I throw it back together. The only other thing I think it could be would be a rod bearing but I honestly just don't see how that can happen on one of these motors. I should know later this week or next week at the latest depending on shipping.
Yes, I agree with what you say. When you don`t have all of the information it`s easy to come to the wrong conclusion.Think it was a JV between T1/ETS and Tilton so doubt it there are any issues with engineering as it’s sold on the shelf. If OP made any changes well then yes I would agree. Think the black oxide helps during the hardening process.
T1 also sells a flywheel ARP bolt upgrade to help stop fretting.
