Q & A
What is the main focus of this STEMCO's quarterly tech talk?
-The main focus of this tech talk is on Kaiser Quick Kit and Quick Tie, discussing their features, benefits, and the process of installation and maintenance.
What are some indicators that it might be time to check your kingpins?
-Indicators include inconsistent tire wear related to camber, complaints of popping or other noises from the system, steering issues, and the truck seemingly steering itself.
What tools are typically used to check the kingpin for wear?
-A dial indicator and a magnetic dial indicator are used, typically with a bar to apply pressure and check for any inconsistencies over 10 thousandths of an inch.
How is the kingpin system disassembled for inspection or replacement?
-The process starts by wearing proper PPE, removing the brake assembly and hub assembly, and then removing the plates, draw keys, kingpin, spindle, and bushings while noting their locations and conditions.
What are the steps to measure and verify the axle eye's condition?
-The axle eye is measured using a T-gauge and a micrometer at different locations for an accurate reading. The specs can be found on page 27 of the Kaiser catalog, and the measurements should be within 3 thousandths of the specified size for the kingpin kit being used.
How are the bushings removed and replaced in the kingpin system?
-Standard bushings are removed using a bushing driver, while spiral bushings may require a screwdriver and T-handle tool. The new bushings are installed starting at an angle by hand and then pushed further in using the T-handle tool, possibly finishing with a brass hammer if needed.
What is the purpose of the Quick Tie and its different part numbers?
-The Quick Tie is a heavy-duty assembly designed for different weight applications, with part numbers for 12,000-pound and 16-20,000-pound applications. It adjusts from 57-3/8 to 73-7/8 inches, allowing it to cover a wide range of applications.
How do you determine the correct Quick Tie assembly for a specific application?
-You measure the minor OD of the taper or use a guide to determine the appropriate size. The two different part numbers correspond to the two different weight capacity applications.
What is the significance of the blue clamps on the Quick Tie assembly?
-The blue clamps indicate the curb side of the vehicle. They are only on one side to help technicians know which side to set up and to avoid confusion in the future during replacement.
How is the reassembly process for the kingpin system carried out?
-The reassembly involves installing the new lip seal, bushing, kingpin, bearing, and shims, ensuring proper alignment and fit. The lock keys are torqued down, and the plates are replaced with new ones from the kit. The assembly is then greased and checked for proper alignment.
What are the final steps after reassembling the kingpin system?
-The final steps include reinstalling the hub assembly, following the TMC procedure for bearing adjustment, putting the brake assembly back on, torquing the wheels, and double-checking the work to ensure it's within spec. An alignment and test drive are then necessary.
What is the process for installing the Quick Tie assembly?
-The process involves measuring the old assembly, setting up the new assembly to match its length, and ensuring even threading out of the ends. The new assembly is then installed by threading on the castle nut, torquing the clamps, and installing cotter keys.
