RIPCORD GRIP TEST

TM 10-1670-287-23&P 0006 00 0006 00-2 b. Attach a 7-pound weight to ripcord grip handle and suspend weight from handle, exercising care to apply load gradually without impact. Hands or lifting device, as applicable, must be fully removed from weight. NOTE The ripcord-locking pin will withstand a 7-pound load without assuming a permanent set. c. Remove weight, rotate locking pin one-quarter turn, and test pin again by reapplying the load as prescribed in step b. d. Repeat procedure in step c. until locking pin has been tested in four positions and rotated one- quarter turn prior to each test. NOTE Each locking pin on a ripcord length will be tested under load in four positions. e. Remove weight from ripcord grip and remove locking pin from test block. f. Visually examine tested locking pin to ascertain if it was marred, cracked, or distorted during the test under load. If any defects are noted, remove ripcord from service. g. Repeat procedure in steps b. through e. for the remaining locking pins on the ripcord length. After testing all locking pins, if there are no visual defects apparent, test each of the locking pins for bends. h. Place locking pin in vertical position with pin end facing up and either clamp the pin between two wooden blocks at a point below the pin shoulder (as shown in B of the illustration on the previous page) or hold between thumb and index finger of one hand. i. Using test gage, manually locate hole in the block over the end of the secured pin, allowing for ¹/₁₆-inch maximum insertion. j. With axis of gage, block hole aligned with axis of locking pin, then release gage block and allow block to fall freely. k. When weight of gage block falls to cause full penetration of the pin into the gage block hole, the pin is excessively bent. Remove ripcord from service. l. Repeat the procedures in steps h. through k. for each of the remaining locking pins on the ripcord length. m. Position ripcord grip on a fixed hook from a corner nearest the weld.
