If I change the bearings for the rods, will I have to resurface the crankshaft? Is it really necessary?

 

unless there is something wrong with it you dont have to

 

Just changing rod bolts and doing a bearing change for safety. So it's ok to just change the bearings?

 

sounds like a good plan. no need resurfacing the crank unless scarring or wearing is visibly occurring as stated above. make sure to check your clearances upon reassembly

 

Oh yea and what are the specs for the measurements?

Uh oh...how do I know what color to order?

 

you have to measure it with plastigauge or with a dial indicator
