the three categories of equipment. The inspector is responsible for the following:
1. Performing the scheduled inspection, completing the appropriate record forms, and noting deficiencies clearly on the Equipment Repair Order or Shop Repair Order
2. Checking the file of operator trouble reports before equipment inspection
3. Using the latest testing equipment and methods available to the unit or public works department
4. Performing minor adjustments incidental to the inspection
5. Delivering the initialed Equipment Repair Order or Shop Repair Order to the maintenance supervisor or shops supervisor
6. Road testing or field testing the equipment before and following the PM, repair, or overhaul
7. Releasing the equipment to full service "ONLY" after final inspection is completed
Inspectors will immediately notify the maintenance supervisor or shops supervisor whenever suspected vehicle abuse or reoccurring mechanical failures occur.
The three types of inspections performed at an equipment maintenance shop on a public works station are reliability, acceptance, and safety.
The safety inspection is done once a year or every 12,000 miles, whichever occurs first. All deficiencies found should be corrected before the vehicle is returned to service. Automotive safety inspections include the following:
1. Brake system. Road test to determine if the brakes are functioning properly. Check brake pedal free travel, Remove the wheels and inspect drums and rotors for wear or cracking. Inspect the pads and lining for excessive wear. Check all brake calipers and wheel cylinders for damage or leaks. Inspect all hydraulic broke lines for leaks, and check the brake fluid level. On air-brake systems, inspect air-brake accessories, air lines, and air tanks for leaks and deterioration. Check air-broke instruments, air control valves, trailer hoses, and glad hands.
2. Steering and suspension system. Check all steering devices and linkage for wear or damage. Inspect all suspension bushings and pivot points. Check all suspension parts for wear or damage.
3. Shock absorbers. Check for leakage and proper operation.
4. Tires and wheels. Check tires for damage or excessive wear. Front tires of buses, trucks, and truck tractors will be replaced when less than 4/32-inch tread remains. All tires will be replaced when less than 2/32-inch tread remains.
5. Fuel system. Check all fuel lines and fuel line connections for signs of leakage. Inspect fuel filter housings for signs of leakage or damage.

For the annual safety inspection on construction and allied equipment, use the correct manufacturer's maintenance and repair manual for guidance.
To avoid unnecessary downtime, coordinate and perform the safety and reliability inspections at the same time. Figure 9-2 is one example of a standard inspection sheet used at some public works stations. The inspection, lubrication, and adjustment functions andContinue Reading
