5. FAQ

Q: why the shim 144-15-21270 need different thickness ?

A: In heavy machinery like komtu equipment (where part numbers format like 144-15-21270), shims are manufactured in varying thicknesses because they act as precise, customizable spacers. Their main purpose is to account for tiny variations in metal components and to set exact mechanical tolerances during assembly or repair. Different thicknesses are required for several key reasons:

Compensating for Manufacturing TolerancesEven with high-precision manufacturing, no two heavy steel castings, housings, or shafts are 100% identical. One transmission cover might sit a fraction of a millimeter deeper than another. Offering the shim in different thicknesses allows the mechanic to select the exact combination needed to square up the components perfectly without needing custom-machined parts.
Setting Axial Play and BacklashIn components like transmissions, final drives, or bearing cages, you must maintain a highly specific amount of "axial play" (end-play) or gear backlash.Too tight (no shim/thin shim): It causes excessive friction, overheating, and rapid bearing failure.Too loose (thick shim): It causes vibration, misalignment, and gear teeth to chip or wear unevenly.By stacking or swapping different shim thicknesses, a technician can achieve the exact specified gap (e.g., 0.15 mm).
Adjusting for Wear and Tear over TimeAs heavy equipment operates under extreme stress, metal naturally wears down, expanding the gaps between moving assemblies. During a rebuild or maintenance interval, the original thin shim might leave too much "slop" or play in the assembly. A technician will measure the new gap and install a thicker shim (or a different combination) to bring the assembly back to original factory specifications.Standard PracticeTypically, parts ending in a standard sequence like this will belong to a shim kit or an engineering set where you can order specific variants (e.g.,0.1mm, 0.3mm,0.5mm). Technicians use a micrometer or feeler gauge to measure the existing gap, then choose the precise thickness required to fill the void.

Q: What happens if it’s not used or installed incorrectly?
A: Without the lock plate, bolts can vibrate loose over time, leading to component failure, leaks, or catastrophic damage to the powertrain. Improperly bent tabs will fail to lock, offering no protection.
