<br />Miller Trailers receive a thorough preventive maintenance in-
<br />spection every 20,000 miles.
<br />spection. In addition, the water
<br />filter element is changed, engine oil
<br />and filters are changed, and product
<br />blower gear oil is changed. Any
<br />repairs made or defects noted during
<br />the L or LO inspections are noted on
<br />the inspection sheet.
<br />B Inspection
<br />Miller's B inspection takes about
<br />four hours to complete, and involves
<br />the checking or adjusting of approx-
<br />imately 90 items on the tractor.
<br />Each mechanic has a procedure
<br />book which tells how to conduct
<br />each function on the B inspection.
<br />Mechanics are instructed to com-
<br />plete the B inspection in sequence,
<br />noting any defects which might re-
<br />quire additional attention. At the
<br />completion of the inspection, the
<br />mechanic gives the complete form
<br />and list of any defects to his foreman
<br />for further instructions (details of B
<br />inspection presented elsewhere).

<br />AI Backstrom checks MC•312 trailer shell thickness with~a
<br />Krautkramer Branson DM2 electronic thickness gauge. All
<br />MC•312 trailers are checked annually for shell thickness. Top
<br />and bottom checks are made of front and rear heads, and at
<br />front, middle and rear of shell. Trailers not meeting Miller stan•
<br />Bards are retired from MC•312 service.
<br />In addition to the L, LO, and B
<br />inspections, there are other mileage
<br />interval operations performed on
<br />tractors. These servicings are in-
<br />itiated by a form sent from Jackson
<br />maintenance management to the ter-
<br />minals. After the operation is com-
<br />pleted, the form is returned to
<br />Jackson with date and mileage at
<br />which the work was completed.
<br />Other work includes engine air filter
<br />change at 150,000 miles, air dryer
<br />element change at 200,000 miles,
<br />water pump change on Detroit
<br />Diesel engines at 200,000 miles, rod
<br />and main bearing changeout at'
<br />250,000 miles and Bendix fan hub
<br />changeout at 200,000 miles.
<br />Miller has no set schedule for in-
<br />frame overhauls. Four terminals are
<br />equipped to perform in-frames. Out-
<br />of-frame work is sent to the rebuild
<br />shop in Jackson. Jackson maintains
<br />several spare rebuilt engines which
<br />can be exchanged with terminals
<br />sending engines in for rebuild.
<br />Trailer Maintenance
<br />As with tractors, new trailers
<br />receive a thorough inspection before
<br />being placed in service. Miller
<br />Transporters has increased the size
<br />of its trailer fleet in recent years as it
<br />uses its nationwide authority to a
<br />greater extent. Many of the newer
<br />trailers are MC-307 stainless steel
<br />single compartment trailers which
<br />afford the greatest opportunity for
<br />backhauls.
<br />The trailers are specified with a
<br />temperature rating of 400 degrees F,
<br />increasing their versatility. This re-
<br />quires the use of a ten gauge rather
<br />than 12-gauge shell, which increases
<br />trailer weight, but does provide a
<br />stronger, more durable trailer. The
<br />higher temperature rating also ne-
<br />cessitates the use of a Carbone rup-
<br />turedisc rather than a fusible cap for
<br />Modern Bulk Transporter
<br />truster Banks Jr inspects fire in fire area of Mobile shop. Miller
<br />radial tires are aired to 90 psi. If a fire has dropped to 75 psi
<br />or below, it is pulled to detect the reason for air loss.
