MR50 Connecting Rod pin and bearing kit replaces the original caged roller bearing with a superior shell bearing and a new hardened steel crank pin. Your rod and thrust washers should be good. We don't have replacement rods or thrust washers.
Please look at the pictures of galled rod bearing race and the completely blown big end needle bearing that comes from blown crank seals and poor oiling through incorrect premix ratios. These would be examples of needing a new rod. As long as the lower end rod race is good, this bearing kit will work. You will need to find a machine shop to do the work, but we'll guide them. If you can't find a shop we might be able to recommend one or we are set up to handle it here.
