Hi RC,
you may be able to get your bronze backed shells re-babbitted local and you can then cut the clearances down to specs. by making them thicker than standard to account for the wear on your journals--may not be cheapest option but would get by your worn crank.
OM has given you the standard running clearances as 0.0045"-0.006"
Max. clearance for those big end shells from the SRB is given as 0.015"
Max wear on big end journal is given as 0.009" and max. ovality as 0.007"
Cheers,
Eddie B.
Thank you OM for spending the time to upload that information as that is perfect. Yes edb have dropped one off at the local man to thick about building them back up but as you say the cost may out way everything. Have pulled a set of pistons out of a later model 3T engine so will be using them but as you know the crank is bigger in that so rods and shells no good to me. Thanks for help
