Hi,
I have a 1988 F-250 that was formerly a 7.3 IDI/C6 combo but which I have now converted to a 6.9 IDI/ BW T-19 drivetrain from an '85 F-250 w/120k. Anyways, the 10.25 in rear, T-19 tranny, and 6.9 motor are in excellent shape, and I have installed a new 12 in clutch w/resurfaced flywheel. Do you have any idea what the tow capacity of a vehicle like this is? The max gross weight w/ the auto was 13,000 lbs. Does being a manual affect capacity? Is there a best way to feather the clutch when starting out? I intend to use this vehicle for extended highway hauling, particularly car trailers, and was hoping a manual would cut down on the heat buildup and improve fuel economy.
Thanks - Andy
I'd say that stick should help out pulling hills and such, but the real problem is how much can you safely stop? If you have (working) trailer brakes, then no problem. My single axle boat trailer doesn't have any, so stopping can be an adventure if everyone in front of you slams on the brakes.
I have towed around 20,000 gross with the 6.9 and the same setup you have. My gears in the axle is 3.55 ratio.
You will have lots of time to look at the scenery while pulling hills.
Good trailer brakes are a must for any downhill grade.
I have mine licensed for 20,000, and the truck weighs 8000 so that leaves me 12,000 for the trailer and load.
I tow equipment around a bunch and am looking to get a 6 speed tranny for mine so the hills are a little easier to start out on here in WV.
