hey looking for some info on line bored blocks I got 5 here all different measurements need to find the specs for
standard thrust standard mains with #4
1st over thrust and mains with #4 2nd over thrust and mains with #4 3rd over thrust and mains with #4 4th over thrust and mains with #4some of these blocks appear to have some mains at std and others at first cut but looking for good #'s to go by
metric and imperial welcome
Std size for 1/2/3 is 65.00-65.02mm std size for 4 is 50.00-50.03mm
Oversizes are in .25mm increments (~.010".)
std thrust is 22mm, std undersize is 21mm, but good shops like RIMCO will cut intermediate widths and supply modified bearings. Look for a
5 digit number stamped just outside where the flywheel seal would fit. This number would specify the bore oversize and the #1 main bearing web width both in thousandths.-
