[AT] Allis 7030 running warm

[Cecil R Bearden]

I finished disking this afternoon with the 7030.  I installed the 
duals,   Duals were fun with my bad back and bum leg...removed the blown 
muffler and installed a straight pipe about 16 inches above the cab.  It 
really doesn't sound too bad.  Probably forget the muffler.
  I washed the radiator out 4 times during the 10 hours of running,  I 
have 2 gauges installed, I cannot tell where each one is connected.  One 
would run as hot as 265 deg and the other would run up to 195 
sometimes.  As I had said earlier, there are 2 connections with heat 
gauge lines in the top rear of the thermostat housing.  It appears this 
is where these gauges are connected.  I could not tell for certain 
without an extra pair of hands.  However, I cannot see how one could 
really be running at 265 without the radiator boiling over.  I was not 
loosing coolant, so I kept running.    Maybe this gauge is connected to 
the hyd oil.....
There should be a baffle plate between the engine and the cab as the hot 
air pouring into the cab from around the steering column and the 
throttle is like sitting in front of a hair dryer.  A/C was putting out 
cool air, but the input of heat from the engine and the R-134 
refrigerant kept the cab at about 90 deg.  It was only 85 outside, so 
........
The dash area would get so hot you could not hold you hand on it.   It 
will soon get some insulation and a heat baffle.   I am thinking of 
using some of that fire stop foam in a can....

The old girl pulled the disk pretty well.  I had to go over some places 
more than 6 times to get it loosened up.  This ground was packed far 
more than I expected by oil field mud application.  The compaction was 
nearly the same all over the field,  I could not note any wheel 
tracks.    I don't think I can drill wheat in this as it has too many 
clods.   I may be able to broadcast fertilizer and then use the spreader 
to broadcast wheat and harrow it for cover.  The drill will probably 
over it too deep.
