If the finals fill passages are like I think make sure you clear all the grease out so you know it is truly full. IIRC when the oil level is up to the top of the fill hole it is full. next time you go to Holt check on price and availability of track rollers, either new or rebuilt. I have a feeling having the old ones built up and turned will be near or more the price of new. There also might be after market rollers available too. Not trying to push you buy them now, just give yourself time to shop around and compare.
