CK-109 Hot Rods Crank loose fit

244 Views 3 Replies 4 Participants Last post by  Mr Scary
After splitting my cases to check the crank/bottom end, I found that the crank will slide right into the case/crank bearing with little effort and will also slide right out as well. I am thinking that this is a sign of major wear on either the crank and or bearing or both?

Guidance greatly appreciated.

Only way to know for sure is to mic them. Since you have split the cases I would suggest replacing the bearings.

One side may be an interference fit while the other is a slip fit--tight but can be pushed on by hand. I can't remember for sure, it has been a while since I serviced the crank. It may also be a matter of whether you're dealing with an OEM or aftermarket crank. If both sides slip, then you probably have a wear issue.
If it's wore out and doesn't come up in spec I have a complete bottom end. Just saying
