[AT] Allis 7030 running warm

[charlie hill]

Cecil,  is it possible that one of those heat gauges is showing oil 
temperature?  Does
the 7030 route oil through a cooling coil in the radiator?   I don't have a 
clue.  Just
thinking it might be a possibility.

If the radiator caps are good it should be able to run 210 to 220 without 
blowing out any
coolant and it should be ok running that hot.

The 7030 has the 426 ci engine in it and I think it's rated in the 7030 at 
about 130 hp and about
110 drawbar hp.  however, that same engine with the addition of an 
intercooler in the 7080 is rated
above 200 hp.   Allis Chalmers farmers had a habit of turning the screws on 
the injector pumps
so yours might be turned up.

Here's a video of a 7045 and an 8070 working the same field.  The 7045 has 
the same engine as yours
just turned up a bit and the 8070 is the intercooled version of the same 
engine.

What depth are you running the offset?  In compacted soil (oil well 
equipment) the compaction is severe.  Figure at lease 10 hp pr foot(16)=160 
hp + in compacted soil and (what depth)>  I think you are running the old 
girl harder than you think.  Just a NOT green tractor fan.
