hiwy50 Posted July 17, 2016 Share Posted July 17, 2016 Third weekend in a row I have driven my B61 to a ATHS function, total 1032 mi. Temp 100 degree, dog house makes it hot. I really respect the old timers that did that every day. Question of the month. How long is a 711 dipstick?? Cable on mine, like a speedometer cable, is unraveling. Not sure of oil level.

Freightrain Posted July 18, 2016 Share Posted July 18, 2016 I put about 14 yrs and 50K miles on mine without any A/C. It sure is nice now that it does have it. I put up with it long enough.

hiwy50 Posted July 18, 2016 Author Share Posted July 18, 2016 Freightrain--- Mine runs 52 MPH at govoner setting of 1900 RPM with 4:24 gears. What speed does yours run and at what RPM. Thinking on changing govener to 2200. Richard Quote Link to comment https://www.bigmacktrucks.com/topic/46077-driving-a-b61/#findComment-339607 Share on other sites More sharing options...
Freightrain Posted July 18, 2016 Share Posted July 18, 2016 You must have a direct box? I have single over triplex(and with old 4.62 gears it would run 65 at 2100 rpm). With 4.10's now it will go 72 mph. I've run it flat on the governor for lots of years going 65 dragging my trailer. The ol 673 didn't really care. 1 Quote Larry 1959 B61 Liv'n Large......................

mowerman Posted July 25, 2016 Share Posted July 25, 2016 Aren't you in the middle of changing your engine??? Bob Sent from my XT1096 using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/46077-driving-a-b61/#findComment-340375 Share on other sites More sharing options...
Freightrain Posted July 25, 2016 Share Posted July 25, 2016 I did change it. But the ol 673 ran on the governor for many years without any problems. I drove it with my foot firmly planted on the floor, all day, every day at 2100 rpm. It's strange now, how I just feather the throttle to run along at speed. A little boost goes a LONG way. 1 Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted July 26, 2016 Share Posted July 26, 2016 Yes, they always say to leave some pedal, but hell, it wouldn't get anywhere if I did that. I ain't got that much time to get to the races. I might not have had it 100% on the floorboard, but likely 99.8% most of the time LOL! 1 Quote Larry 1959 B61 Liv'n Large......................

mowerman Posted July 27, 2016 Share Posted July 27, 2016 Ya know what you mean I'm not sure what I'll wind up doing.... If I ever get the truck in ready condition for show I might try to put a brownie behind the triplex who knows finally ready to build my shop and not getting any younger. May just wind up enjoying in locally ....bob Sent from my XT1096 using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/46077-driving-a-b61/#findComment-340533 Share on other sites More sharing options...
