CHAIN TENSION MEASURE LAB (JCB JC400/G0713)

A worn chain tension measure lab can lead to inaccurate tension readings, risking chain failure or uneven load distribution. This aftermarket replacement part references JCB catalog number JC400/G0713. The device functions as a specialized gauge for measuring chain tension in mechanical systems. Its primary mechanical role is to provide a direct readout of tension force applied to a chain. A common failure consequence of a faulty unit is undetected chain slack, which may cause sudden component stress or breakage. During routine checks, a technician might notice erratic readings that indicate the lab requires replacement. Verify the serial number or application, then call (562) 693-7748.
