Deuce dies uphill

[demonhunter77]

So, I was driving my deuce bobber home from getting a full bumper put on the back and she stalls out going up a steep hill to my place. This is the second time a hill has stalled her out. Suggestions on what to look for? I'm not very diesel inclined yet.

How much fuel was in the tank? Was it diesel? Stock tires? m35a2 deuce? Gear? Speed? How old are the filters? Runs like a scalded dog on flat ground?

Must be one heavy bumper...

I would try adding at least another 10 gal of diesel to tank. If that solves problem, replace rubber hose on in tank fuel pump.

Gimpyrobb,

Full tank if road diesel. 35 degree incline. 3rd gear. Runs great on flat ground. M35a2. As it stalled I believe I was at 5 mph. Fuel filter should be about 4.5 years old with 600 miles on them.

The last time I ended up with air in every injector and she wouldn't start back up. This time I pegged the pedal and got her to recover.

You were in 3rd gear (high range?) going 5mph up hill when you stalled? What happens if you shift into a lower gear?

 

[demonhunter77]

I would say I saw 5 to 7 mph on the speedo as she started to stall. She was going more lIke 20 before the slope change. In hind sight, yes, I was still in high range. Steepest on road hill ive ever seen. Lmbo. Goes from 20 to about 35 degrees half way up the hill where she slowed and sputtered.

Mike,

I downshifted and punch it. Then she recovered after some more sputtering for like 2 seconds. I kept the pedal to the floor to get her up the hill after that.

Above first gear I don't like to let the RPM's drop below 1500, in the two higher gears I downshift between 1900 and 2000 to keep the air flowing through the exhaust (lower EGT's). YMMV.

 

[demonhunter77]

I'LL be traversing this hill every time I drive her now that I've moved. So, stalling is no bueno.

This is where I should've read up more on diesels. Sounds like it's my technique rather then mechanical issues then?

That's what I'm thinking. I'd downshift sooner.
The operator's manual (-10 TM) covers this.

I believe the power band(most hp and torque) is about 1700rpm. I'll see if I can verify that number.

Talked with another deuce owner who has driven that hill. It is definitely my driving that was the problem. He has to downshift and up the rpm well before I tried. Now I know. Thanks guys for putting up with my silly question.

No question is silly if you don't know the answer to it. Of course after you get the answer then we will laugh and make fun of you ! Just kidding ! Remember the TM's are your friend !

Here's a tip I use when down shifting my Duece, as you move into neutral, give the gas a double tap, hitting lowered gears as your slowing and hitting those hills. It helps.

 

[glcaines]

Don't forget that you can also shift the transfer case into low range while moving - it is synchronized.

 

[wreckerman893]

Drop into low range well before getting to the hill, find a gear it will pull in that will allow you to hold around 15-1600 RPM (prob third) and let her pull all the way to the top. The engine does not have to be screaming for the truck to be pulling. That is why you have Low and High ranges.

My guess is that there is still some underlying problem since even if the engine stalls out due to lugging it should still not run out of fuel.

But I only been driving these things around 40 years so what do I know.

 

[demonhunter77]

Thanks for the advice guys. No problems going up the hill today!
