OFFICIAL SURVEY
OFFICIAL SURVEYTechnology & Maintenance CouncilIssued:July 22, 2020Turning Experience Into PracticeAverage Standard Repair Times (SRT) for98 Commonly Performed Labor Tasks inFleet and Service Provider OperationsDeveloped by the Technology & Maintenance Council (TMC)ABSTRACTFifty TMC member fleet and service provider members responded toTMC’s second “Fleet & Service Provider Average Standard RepairTime (SRT) Survey,” which was administered in the first quarter of2020. The purpose of the study was to aid in establishing baselinerepair times that will improve shop productivity and profitability. Thisis the second year that TMC has conducted the survey, giving themembers a comparison of year-to-year SRT data.The survey was based on Vehicle Maintenance Reporting Standards(VMRS) making it easier to aggregate repair times. Participantswere asked to provide the time in hours to install specific parts or toperform needed labor in their facilities, not the rates that participantsnecessarily charge their customers.Data presented in this report is based on the labor description andthe corresponding VMRS Code Keys for each task using VMRS CodeKeys 15 (Work Accomplished) and 33 (Component Code). Onceagain, repair and replacement of clutch assemblies and automatictransmissions were reported to be the most labor intensive tasksfollowed by EGR cooler, replacement of the air brake compressoredged out radiator replacement this year. Of the 10 most labor intensive tasks, two were related to emission/exhaust and converselythree of the least labor intensive tasks were associated to brakesystem related repair/replacement.Technology & Maintenance Council (TMC)950 N.

INTRODUCTIONTMC’s S.5 Fleet Maintenance ManagementStudy Group is responsible for the maintenanceand oversight of the Vehicle Maintenance Reporting Standards (VMRS) through its VMRSCodes Committee. One of the objectives ofthe VMRS Codes Committee is to developmeaningful benchmarking data based on theVMRS coding convention.Accordingly, TMC’s S.5 Fleet MaintenanceManagement Study Group directed its VMRSCodes Committee to conduct a labor time studybased onDeletefleet andservice providermembers’Reply all Archive Junk Sweep Move toself-reported repair and installation times. Thepurpose of the study was to aid in establishingbaseline repair times that will improve shopproductivity and profitability.The survey was based on VMRS Code Keys15 (Work Accomplished) and 33 (ComponentCode), making it easier to aggregate repairtimes. Participants were asked to providethe time in hours to install specific parts orto perform needed labor in their facilities, notnecessarily the rates that participants chargetheir customers.TMCUndorealized that reported times would varydepending on the brands involved in certain installations.Therefore, participants were askedTMC Survey -‐ Average Standard Repair Times for Common MaintenanceTasksto list the “average” repair time for the brandRobert Braswell tmc@trucking.org Replyuseall most often.

The objective is to determinebaseline repair times that will improve shop productivityand profitability.The survey is based on the Council’s Vehicle MaintenanceReporting Standards (VMRS), which will help the Councilin aggregating reported SRT data. Participants are askedto provide their average times in hours for the 100 commonmaintenance tasks listed. NOTE: TMC is collecting data onactual labor/repair hours – not rates that participants maycharge customers.Please provide data for as many of the 100 repair tasks asyou can, based on your operation. You do not have toanswer all 100 questions.We do ask contact information in order to follow up withyou should questions arise, you may also choose toanswer anonymously.All response will be kept strictly confidential and onlyaggregated results will be shared by TMC.To take the survey, go to:Average Standard Repair Times for Common Maintenance TimesSurveyThank you in advance for your participation!The survey was conducted using SurveyMonkey. Eblast alerts were generated usingBluehornet’s High Roads email managementsystem. Fifty individuals attempted to completeat least a portion of the survey. The survey wasactivated on February 24, 2020. The surveywas closed April 1, 2020.The survey was initiated by S.5 Fleet Maintenance Management Study Group ChairmanAmanda Schuier, VMRS Codes CommitteeChairman Paul Moszak, and administered byTMC staff members Robert Braswell, TMCexecutive director; Jack Poster, VMRS servicesmanager, and Cori Hicks, TMC administrativecoordinator.Figure 1Comprised of a broad collection of experienced fleets, suppliers andservice providers, TMC is the only industry association that is focusedsolely —TMC/ATAon truck technology and maintenance.

In developing the survey, TMC staff identified —with the assistance of members of the VMRSCodes Committee — 98 commonly performedlabor tasks on powered equipment as experienced in typical fleet and service provideroperations. Each of the following labor taskswere tagged with the appropriate VMRS CodeKey 33: Component Code and Code Key 15:Work Accomplished Code to facilitate datacollection and analysis. For the purposes of this study, “R&R” was de- fined as Code Key 15; “Code 03: Replace With New,” which means to replace a damaged or worn component with a new component. The 98 labor tasks are as follows: R&R Brake Lining, Per Wheel - Steer Axle R&R Brake Drum, Per Wheel - Drive Axle R&R Brake Lining, Per Wheel - Drive Axle R&R Brake Drum, Per Wheel - Drive Axle R&R Brake Rotor, Per Wheel - Steer Axle R&R Brake Rotor, Per Wheel - Drive Axle R&R Brake Caliper, Per Wheel - Steer Axle R&R Brake Caliper, Per Wheel - Drive Axle R&R Slack Adjuster - Steer Axle R&R Slack Adjuster - Drive Axle R&R Slack Adjuster - Automatic, Steer Axle R&R Slack Adjuster - Automatic, Drive Axle R&R Brake Chamber/Cylinder Assembly - Steer Axle R&R Brake Chamber/Cylinder Assembly - Drive Axle R&R Brake Hose - Hydraulic, Steer Axle R&R Brake Hose - Hydraulic, Drive Axle R&R Gladhand - Service & Emergency R&R Gladhand - Service R&R Gladhand - Emergency R&R Tractor Protection Control Valve R&R Brake Air Compressor R&R Air Governor R&R Foot Valve R&R ABS Modulator Valve R&R Wheel Speed Sensor R&R ABS ECU R&R Alternator R&R Alternator/Generator Belt 2020 —TMC/ATAR&R Idler PulleyR&R StarterR&R Starter RelayR&R BatteryR&R Power Steering PumpAdjust Wheel Bearings - Per WheelRecharge A/C SystemR&R A/C Expansion ValveR&R A/C AccumulatorR&R A/C Receiver DrierR&R A/C BeltR&R A/C Evaporator CoreR&R RadiatorR&R Water PumpR&R ThermostatFlush & Fill Coolant SystemR&R Radiator Hose - UpperR&R Radiator Hose - LowerR&R Engine Serpentine BeltR&R Wiper Blade AssemblyR&R Wiper Arm Linkage AssemblyR&R Clutch AssemblyR&R Automatic TransmissionR&R TurbochargerR&R Charge Air CoolerR&R EGR CoolerR&R EGR ValveR&R DEF TankR&R DEF Tank HeaterR&R ELD - Electronic Logging DeviceR&R 7 Pin Connector PlugR&R Trailer Junction BoxOverhaul Fifth Wheel AssemblyLubricate Fifth WheelR&R Fuel TankR&R Fuel Tank Sending UnitR&R WindshieldR&R Wheel Stud - Per WheelR&R Auxiliary Heater AssemblyR&R TireR&R Shock Absorber - EachR&R Intake Manifold GasketR&R Exhaust Pipe StackNew Truck In-serviceR&R Cab Height Control ValveR&R Doser Valve AssemblyR&R Camshaft Position SensorTMC Standard Repair Time (SRT) Survey Report (2020) — 4

R&R A/C SIONAs in the previous 2019 survey, repair and replacement of clutch assemblies and automatictransmissions were reported to be the mostlabor intensive tasks, followed by the EGRcooler. In 2020, brake air compressor replacement proved to be more difficult than radiatorreplacement. Of the 10 most labor intensivetasks, two were related to emission/exhaustand two were related to drive train repairs.Conversely, three of the least labor intensivetasks were associated with brake systemrelated repair/replacement. TMC intends torepeat this survey on at least an annual basisand will keep expanding the number of labortasks covered.TMC Standard Repair Time (SRT) Survey Report (2020) — 5
