In a chain drive system, initial calibration or adjustment for take-up or compensation of the manufacturing and assembly tolerances is achieved by an adjustment device that comprises a fixed block (12) and a spring-loaded moveable pad or snubber member (14), which, after initial positioning for take-up of tolerances, is fixed in position on the body. The adjustment device(10) can generally be positioned on the tight portion of the chain and can be an independent device or it can be combined with a traditional hydraulic or mechanical tensioner for taking up slack due to wear.
