Non-Productive Work

Analysis of past SRT time studies reveals the following general types of work that were not considered to

be productive:

− Waiting on camshaft gears to heat and cool

− Waiting on another mechanic to finish using special tools or shop equipment

− Hunting for misplaced parts

− Repairing shop equipment

− Sorting through capscrews, to find the correct length, that were all thrown together into one basket dur-

ing disassembly

− Repairing customer supplied components

− Salvaging parts or tools that have been damaged from improper handling or lack of correct tools

− Clearing off tables, parts carts, parts racks etc. left dirty or loaded with parts from previous

repairs on other equipment

− Rework caused by installation of incorrect parts or incorrect installation of correct parts

− Fabrication or modification of special tools or equipment because the correct tools or equipment are not

available

− Visiting during non−break time

− Conducting business with tool vendors

− Waiting on other mechanics to provide required help

− Waiting on parts clerk to fill orders for other mechanics

− Unnecessary inspection of new parts

− “Hot Setting” valves and injectors when not required

− Repairs to application hardware

− Rework resulting from failure to follow recommended service practices

− Performing work that is not part of the repair order or helping another mechanic

Service Accessibility Codes

Service repairs are affected by engine or generator set accessibility. The more difficult the accessibility, the

longer it will take to complete the tasks given in the SRT procedure. Accessibility for a particular application

is determined by reviewing the application and rating the degree of difficulty for performing the 20 most

common repairs. Four codes (A, B, C and D) are used to classify the degree of difficulty for the service ac-

cessibility of a specific model or type of equipment. An “A” accessibility code indicates the engine or genera-

tor set is easily accessible. A “D” code indicates the application does not make the engine or generator set

as easily accessible, thus the highest degree of difficulty relative to SRT standards. A “S” code is included

for special or specific repairs not covered in the other four classifications. The “R” code indicates the repair

is completed with the component, engine or generator set removed from the application.
