A July 2026 service report for the Kanchanaburi site documents drive-train work on cooling-tower Cells A and B.
Completed scope
replace the gearbox on Cell A;
replace drive shafts on Cells A and B;
record fan blade angle, tip clearance and tip tracking before work;
remove and reinstall drive components;
set shaft-end distance and flexible-coupling gap;
align gearbox and motor using laser alignment;
refill gearbox lubricant;
test run both cells; and
check gearbox and motor vibration after installation.
The original work order identifies an LRF 450.275SS drive shaft for the two replacement sets.
The service report records alignment and coupling-gap checks as within the specified criteria after installation. Detailed dimensional tables remain in the internal report rather than the public case study.
