INTERVAL MAN- HOUR ITEM TO BE CHECKED OR SERVICED CREWMEMBER PROCEDURE EQUIPMENT NOT READY/ AVAILABLE IF: NOTE New style drive sprocket will have an indented circle on one sprocket tooth, on each side of the sprocket. This is for a visible wear indicator for when to reverse the sprockets or replace the sprockets, if both sides are worn to the wear indicator. The wear indicator may not be on the same tooth for both sides. The old drive sprockets will still require the use of the profile gauge to measure the sprocket teeth wear. b. Check sprockets teeth for wear. Use the profile gauge on old style drive sprockets to measure sprocket teeth. If any of the sprocket tooth does not extend beyond gauge or wear indicator (on newer sprockets), notify unit maintenance. Any sprocket tooth fails gauge test or is worn to the wear indicator. c. Check cushions for wear and damage. If cushions appear to be moving on sprocket hub, notify unit maintenance. If track shoes are contacting sprocket hub flange, a thumping sound will be heard. Cushions should be replaced. 0057 00-80 Change 1
