Taking the 1977 Mack RS700L out for a stroll. Just put new head gaskets on and gave her a valve adjustment. Listen to that tip turbine. She's happy again
@@Maddogtrucking for the work those little macks can do and on very little fuel and run forever they are the way to go , but if you really pulling heavy load and very easy to shift and run forever the 3406 is way to go ...... very expensive but also resale almost like new .
@user-lq4mo8dw1p good question. I'm a die hard mack guy use to praise their auto power divider which this truck has but I never really know if the power divider is doing what it should. It will go through some muck but not as well as a truck with a manual power divider with axle lock. if I was to spec out a new truck it would have manual lockers. The pete I drive now has that set up (on air ride) and will go places my mack wishes it could.
@@Maddogtrucking I hauled coal for over 30 years and I've driven almost everything you can think of and may already know this but when it comes to getting a mack power devider to lock up when the wheels are starting to spin you go ahead and rev it pretty high rpm's then quickly let completely off the fuel then go back full throttle quickly and that locks up the rears .....they work if it's done right .
@@thekodiak77i said that because everyone were comparing this old mack with newer trucks with 3406 or c15 but when this truck was made in 60s and 70s caterpilar didn't yet have a good truck engine with engine brake. Comparing cat with this old trucks is stupid, if we are comparing equal engines timeline e9 would smoke the kitty like this mack would smoke 60s cat engines.
I started hauling fuel 45 yrs ago. I drove an r700 that had a 290 Cummins, with a 10 spd. When someone asked on the radio what I had for a motor,,, I told them it was a rolls, canhardly. Rolls like a bitch downhill,, can hardly make it up hill. Boy, come a long way since then.
I always found it odd that original owners bought long hood trucks then spec the small engine. I wonder what the difference in cost a R600 and R700 was with the same specs. If the cost was marginal, then it was bought purely for looks.
@@Maddogtrucking Thats a nice Mack. I wasnt running her down, it just reminded me of my F model with the same engine and had a bunch of problems with the bad castings being warped on the ones that Switzer supplied to Mack. Would take them apart and have them faced off until flat surfaces, then no more exhaust leaks. Take good care of her.
@@Maddogtrucking Good looking ride. Like many I had to have the Duck Truck Model & Trailer , just fascinated me. But way before , not sure of the Album Name , but Red Sovine had a pic on the cover of a Mean Black Superliner I think , with Phantom 309 on it. Had a like for them way back . I was weird I guess my parents said listening to ALL them ol Trucking Songs and know em word for word in the mid 70's , still in grade school. I still had the romantic picture in my mind , and understood the old days and ways back when I started out. All I wanted to do , and cars and Trucks man , that was it lol. Born to late I tell everyone. Found out quick though about the heartaches and strife , and missed time in all them songs. Finaly owned 2 trucks , then it got tough and got out. Disability now , so wont get back in. Dont miss truckin , but miss driving em though.
