Maintenance Tips

A properly maintained truck body or specialty trailer not only extends your equipment life, it is also an important safety measure. Fortunately, maintaining your composite equipment is easy to do and our useful tips will help explain how. 

Select a category to view some general guidelines for the repair and routine maintenance of your refrigerated truck body.

Exterior cleaning:

To keep the exterior of your new fiberglass truck body in good condition, periodic preventative maintenance should be followed.

The body has a beautiful, natural glass finish and will stay this way if it is washed periodically with common strength soap and water (heavy doses of acetone or lacquer thinner should not be used.) High caustic soaps and solutions will cause premature color fade and panel surface deterioration.

It is alright to use a hot water pressure washer system for cleaning, however, to prevent premature deterioration of exterior finish; the water pressure against the surface of the panel should not be extreme. Mild to moderate amounts of pressure are sufficient to apply soap and remove surface dirt.

Finish protection:

For a good finish protection, we recommend applying a coat of wax one or two times a year. Waxing helps protect against every day elements and ultra violet rays, which cause surface deterioration and fading. Many automotive or fiberglass boat waxes can be used. Check the product label for recommended surfaces and application. We recommend a mild abrasive rubbing compound with wax that can be found through automobile parts suppliers.

Mounting bolts:

The tie-down angles are welded to the body long stringers. Angles then fasten to the chassis frame with grade 8, 5/8" flanged frame hex bolts that should be tightened after the first 30 days of operation and re-checked every 3 months thereafter.

Door hinges and locks:

If your equipment has outside rear corner hinges with grease zerks - grease them at the same time as the chassis.

For standard hinges/locks - spray them periodically with white Lithium grease.


Refrigeration cold plates (when applicable):

Defrost recommended when frost accumulation exceeds ½". (Defrost instructions are located on driver side front corner of the body or on the compressor door if skirt mounted).

Lift gates (when applicable):

(The following is a general checklist.  Check the operating manual supplied with your unit for instructions specific to your model lift gate.)

Daily inspection

  • All hoses. Oil leakage.
  • Mounting brackets and bolts connecting lift gate to frame and mount frame.
  • Electric wires and connections.
  • Cylinder covers.
  • Replace faulty parts immediately.

General checklist:

  • Grease lift gate at the same time as the truck. More often under heavy usage.
  • Check the oil level in the tank.  Change the oil once a year.
  • Operate the lift gate throughout its' entire operation and check for noise and damage such as bent parts and cracked welds.
  • Visually inspect hydraulic lines for damage, scratches, bending, or leakage.
  • Check plastic covers and rubber boots on cylinders for damage.
  • Inspect cylinders for leakage.
  • Check all electrical connections. Clean battery terminals.
  • Check for any damage that can make the use of the lift gate dangerous.  Repair this type of damage before using. All repairs should be made by an authorized technician. Use only original spare parts. If in doubt, contact your distributor.

Walk ramps (when applicable):

Lubricate wheels at the same time the truck is greased.
