our 1977 Allis 7060 power director tractor is having hard starting issues, and I feel slight power issues.

 

it has the dealer installed fuel system update, getting rid of the square filter and hand primer for a water seperator spin on, a red holley electric pump, and a small final spin-on.

 

it is very slightly wet at the first filter, enough to make dirt stick, but no drips, so I dont think the issue is that.

 

the filters are a little old, but it seems pretty snappy and responsive when running, and pulls great at 2300, so I dont think there is much of a restriction.

 

does the bleed screw on the small upper filter like to let air in? electric pump failing? check valves anywhere?

 

also, is it normal for a 7060 to be pretty gutless at low RPM on headlands? (1200-1500 RPM) our 2-135 White doesnt mind idling down on headlands, granted its a big 478 cu in. motor, but I dont think a 135 hp tractor should be drastically better than a 160 hp tractor. do you think the fuel issue would cause this gutlessness down low?

 

There was this one time when I slowed down too far on a headland, and was lifting it (sweep plow, blade plow, alfalfa crowner, etc. whatever its called in your area) out of the ground and cramping the wheel and hitting the steering brake at the same time, it stalled. I went to re-start, and it would not pick it up, I cracked the bleeder open, got fuel there, cranked some more, finally had to give a whiff of ether to get it going again.

 

 

most of the time when starting it for the day, a guy needs to feather a slight wiff of ether to get it running. sometimes it will start by itself, but about 1/2 to 2/3 of the time it needs ether.

 

I havent tore anything apart, and really dont want to go through and replace everything I think it may be, so any input to common issues on this fuel system would be greatly appreciated, thank you!

long axle, cast center duals, 18.4R38 on power adjust on all 4, 11.00-16 fronts. single battery tray, 3 remotes (2 fact. 1 dealer installed) 2 speaker radio, factory Allis quick hitch and factory top link with handle, and double clevis.

 

a/c almost doesnt work, and seat squeaks with each bump, so not a pleasure to run, but still more enjoyable than a deere. :)

 

It will start ok sometimes though, it isnt consistent either way, so that is what makes me think air intrusion, rather than a bad IP. it will hot restart, just got to bleed and whiff ether, We never have to pour ambient temp water on it to get it to start, which I have heard is the best diagnosis for seeing if the pump is bad.

If the pump does turn out to be bad, what pump can be made to work (aka set to 7060 specs) an L2 pump, they had the 158 hp 670T, or the N6 with the 670HI 220 hp?

 

so the low RPM gutlessness is probably normal? from what I understand about the hydraulics on these, when called upon, they can put a decent load on things, correct? I am thinking the low (like 1000-1400 RPM) RPM combined with the high load was the cause of the stall, not the IP.

also, what was cause oozing under the intercooler? old gaskets giving up, or something deeper? no water in oil, no oil in water. it leaves dusty tear trails. should I re-torque the bolts?

 

finally, how often does the overhead need ran on these? I think I am pickup up a slight whisp at idle.

 

thanks for all the input everyone, it is much appreciated.

 

all I did was flip the washer on the bleed screw, and we opened and shut a plastic bleed screw pre- IP. if there was an air leak, we may have made it seal up, as it starts great now and doesnt bleed back.

maybe it wasnt cranking fast enough either, because we also put a near new pair of interstates in, and it cranks much better.

 

as far as the down low power, cant say if it improved, as this go around with the summer fallow, we got a 15 ft. undercutter/blade plow behind a 7060. :)

 

on that note, with such a light draft load, is it OK to run at 1800 RPM? I am running in low on the PD, 5th on the stick, and low on the range shifter, and am running 1800, and all seems well.

I am aware that too low with too big of load will slip the clutchpacks, but figured under this light of load 1800 RPM is ok, correct?
