[AT] Statistics In Tractor Manufacturing

[Cecil Bearden]

The head was damaged too much to reuse.  I got a salvage one from 
Messicks then had to have it completely worked over as it looked like it 
had been underwater for years.  Messicks then refunded my money for the 
head and the shipping.  They treated me right...

Maybe the original owner used it so gingerly he did not have the 1000 and 2000 hour service done.

He told me that those engines would drop a valve at about 8000 hours if the valve clearance was not adjusted about every 1000 hours.  He also said if they were maintained in adjustment they would run 15000 without major failures.   The UK tractors I was referring to indicated that regular maintenance was performed on them.
