450,000km is a lot different to 197,000km

Interested to know what got it in the end?

In my earlier days lots of engines would have had at least a new set of big-end bearings and possibly mains and rings too by this distance. I wonder if these engines could benefit from at least new big-end bearings at around 300-350K. Older engines would burn oil and the bearings would start to rattle when their bearings got loose whereas these engines would have destroyed the crankshaft before the bearings became that worn.

I’ve always wondered about the feasibility of dropping the sump and doing a bearing roll on the mains as well as the big ends. As mine is a manual, there will be more wear on the thrust bearing and I thought a preemptive strike would be better than another lunched crank.

I wonder if anyone has ever managed to reliably source a bearing set and get the clearances right? Apparently the shells have coloured paint, but surely that would be long gone on a worn bottom end.

A member had his bottom end overhauled as a precaution.

I’m intrigued how you do it with sump off as the crank stays in. Can you slide the top bearing shells in pushing the old top shells out?

IIRC DJ's engine was removed to do the overhaul.

You may know that my 2010 3L had new bearings at 270,000km, mains, big end and thrust. The thrust was well out of kilter by double the tolerance. That was one of the reasons we decided to do it - never good when the crank moves backward and forward that much! Visible movement on the crank pulley.

I’m hoping it’s given me many more years of service as my life position doesn’t allow me to replace mine anytime soon. I’m now 312,000km
