CAT 257B BOGIE WHEEL BEARINGS NO FURTHER A MYSTERY

I'd personally get your time and energy and store all-around for an even better deal. If you're not sure that you need a CTL, you can always incorporate OTT tracks to the wheeled machine, or go with a VTS system. I would be afraid of managing any sort of rubber tracks even though if you'll be in rocky, sharp locations. Just my $.02. Fantastic luck.
