 Posted: Mon Mar 02, 2009 6:25 pm Post subject: Loss of Power in third gear- back again...3-11-09 |
 |
|
Ok I have a 1960 Single cab, 1600 single port, vacuum advance dizzy with the stock trans mission.
I have been driving it daily with out any trouble for a few weeks straight. I have not has any trouble except now I am losing power in third gear. Fist and second gears are great and the truck pulls great through those but as soon as it hits third gear it cant pull the softest incline. On big hills i can get a run at it but it will soon drop speed to about 20mph and i have to downshift back to second. On flat or slight down hill I can shift into third and things seem fine.
I have replaced the fuel filter already thinking maybe it was all gunked up and restricting the flow.
Any ideas?

Definitely full tune up first off.
After that
Check transaxle oil level or change if unknown when last done. Wiggle testing the lower axle for too much play. When changing transaxle oil do a tea leaf reading for any metal chunks from each of the drain points can show a problem before a tow truck is needed.
You did release the E-brake, right???
Check wheels for one that is warmer that may indicate dragging brake problem.
Good to jack up front wheels and see if they spin by hand about the same. Could be bearings in there going bad. When were front bearings cleaned, inspected and repacked with new grease? If unknown do them up!
Remove fan belt and spin gen/alt by hand. Should spin a few seconds after you let it go.
Had a generator get hard to turn. Causing belt squeal at shifting points.

| Bad fuel pump is my first guess then tank screen then leaky dual-port boots if it's a dual-port. |

I have one of the clear fuel filters between the pump and the carb.... it never seems to empty out completely. Single port motor

What about fourth gear?
The ignition timing may be off (retarded), and the grade and the taller gear is causing it to lose power. Give it a full tune-up, including adjusting the valves. Also, check for vacuum leaks.

Did Rick have same problem? Fuel pump is suspect to me. From a standing stop romp on it hard, shift into second quick and stomp it to the floor. If your pump is bad youll lose power there. |

It wasnt happening to rick. The truck has been trouble free since i bought it... untill this of course. That is totally what is happening though. romping into third it just craps out.... maybe i will just just in and do the pump first

Another thought..
I once had the same problem and it turned out to be loose heads. Ended up having to put in case-savers and all was fine.
Does it have an odd 'worbler' sound when it's loosing power? That's it loosing compression around the cylinders/heads... It only shows up when you have the engine under a lot of load.
I hope it is just a tune-up... But if that doesn't fix it.....

I doubt it's a transaxle problem. Do a tune up

Definitely worth a shot, especially if youre running a bocar/brosol pump.
We like to run rebuilt german pumps if possible. |

Maybe I am missing something but why would the problem only occur when it's in third gear if it is the fuel pump causing the problem?
Make sure that the ignition timing is set (free and easy to do) and you can tell by looking at the spark plugs if it has been running rich. Make sure that the carburetor's choke is opening up all of the way.

Had a chance to work on the truck today.
First i changed the fuel pump- no change
new points- no change (points were spanked though)
new carb- no change (but needed to be done... started dripping gas)
new plugs- TADA solved the problem
thanks everyone for your help. It feels good to know that i can roll the truck tomorrow since its going to be 65 degrees out. get to try out my new safaris
THanks again everyone

Good work! Don't take this in the wrong way but next time start with the simple or easiest things and work toward the more complicated.
You fixed it! That's the important thing.

Careful....
Sometimes bad plugs are the problem, sometimes they're just a symptom of a problem someplace else.....
Carry a spare set for a while until you know which you had.
