That's good news, that the main bearing journals are in good order, what is the condition of the white metal man bearing bushes like?

To ensure liner removal with no damage to liner or crankcase, the best way will be to make up a liner extractor, the JP liners are usually quite easy to remove, however be prepared for years worth of rust to drop into the sump when you pull the liner.

LIster JP 1/9 rebuild

More questions about my JP 1/9 rebuild.
I've got a new con rod with standard size big end bearing
The journal on the crankshaft is in need of a gentle burnishing but not grossly out of round.
The averaged measurements taken at 4 points along the length of the journal were:

TDC                 2.991   Inches

TDC + 90        2.995      "

BDC                2.991      "

BDC + 90        2.997      "

I don't have an accurate inside micrometer to measure the new bearing or access to a JP manual with the bearing dimensions and clearance specs
Can anyone help me with bearing clearance?
Heading out to workshop to try and remove the old cylinder liner now.
Thanks

Guys, help me- what's the name of the telescoping T handled devices with allow you to do inside measurement- with your outside micrometer?  I've got a set and they work great.
