[AT] Cat D7E

[Cecil Bearden]

The Case/IH dealer picked up my JX85 to install a loader yesterday. 
Seems they are needing business and he would install the loader for free 
now..  So, I bit...  However, his driver was talking about the problems 
with working on these Tier3 engines and the cost to operate.  He said 
that Cat had quit building Truck engines..  As far as I was concerned 
they might as well have.  I had a 3126E 300hp in a boom truck That would 
not pull a 4% grade at 70mph with a tailwind, and a mile downhill head 
start...  However I have a 70's 3208 that will run circles around any 
other truck I have...

It is interesting that Cat is now using the LeTourneau concept in this 
new dozer.  I thought years ago that LeTourneau was ahead of its time...
