Hello, As I stated in the Intro forum, I'm in the process of buying a 1966 R-600 six wheel dump. This is my first Mack and though I probably could have bought something a little more up to date, it just kind of caught my eye and I gotta have it. I have been using it and as far as I can tell, the truck has been well cared for and is in real good shape. It sports the dependable 237 w/5 spd tranny. Motor is clean and run real strong. No serious leaks that I could find. Tranny shifts good, and everything works. There are a few issues however that need to be addressed so what better place do that than here. -No power steering- This is the one point that's really hard to get past. I'll be using it alot and it's really a PIA to make tight turns..Especially with a load on. Is it possible to retro-fit a power steer unit ? - Drivers side tire- The inside tread(engine side) is wiped out. King pins? -Loses prime when sitting for a while- The owner told me the primer pump was replaced, and it looks new, but it needs a new priming plunger. Could this be the case or is it possibly a bigger problem? I know it's hard to diagnose without seeing. -Parts- How hard or easy is it to get parts through my local Mack dealer or other sources? Well, I get thats enough to digest for now. Thanks.
