3406b bearing roll

hi, i have a 3406b with 200,000 miles on it since its last rod n main , thrust, bearing replacement, was wondering what the recommended service interval is for these or what everyone does them at milage wise, my oil pressure is normal hot n cold , runs fine but just wsnt to do as preventative maintenance,ALSO!, im thinking to do this myself as i learned the old schooler gye who id like to do this job and has done in past is in some serious health conditions he needs to focas on, basically any tips and mains n rod torque specs would be appreciated , its a 7fb engine, should i replace oil pump spring for a new one or stiffer one?whike in there? THANKS!!

 

really! iv never bin told that , just bin told mechanicals should be done every so often, i dont run no special oil in it just rotlla t

 

ok appreciate the information, i think ill a just to do thdm in another 50k that put me at 250k, if they look ok tgen i'll stretch out the interval next time! i think iv found torqueing to 90 and 110 foot lbs plus a flat does this sound correct?

 

thanks alot wore out!!
