Journals :2 ,3, 4: 2.4481-2.4490"
Journal #5: 2.4479-2.4488"
Taper/out of round production: 0.0002", service limit 0.0010"

Con rod journal: 2.0978-2.0998"
Taper/out of round production: 0.0003", service limit 0.0010"

I'm far from lazy. Stupid evidently , but certainly not lazy. FYI I did try searching but came up emptyhanded.
Thanks nonetheless.
