TM 5-3805-260-24ELEVATORThe position of arm (1), with one elevator carrierroller, can be moved to another position to tighten theelevator chain when it is too loose.The elevator chain is too loose when the distancemeasured between the bottom of the elevator frame, halfway between the sprocket and the lower roller, and thechain is more than 10 in. (254 mm). The correct distanceis 6 to 10 in. (152 to 254 mm).ELEVATOR CARRIER ROLLER1. Arm. 2. Holes. 3. Bolt.To tighten a chain, remove bolt (3) and move arm (1toward the chain at the top and install the bolt in one ofholes (2). The torque for the nut on bolt (3) is 300 to 31lb. ft. (410 to 430 N m).If the chain is too loose after arm (1) is moved as faras it can be moved, remove a link from the chain. Onelink changes the length of the chain approximately 3 in(75 mm).When an adjustment is made for the chain on oneside, the chain on the other side of the elevator trackmust have the same adjustment.The sprockets must be in alignment with the rollersor the chains will come off the sprockets. When sprocketalignment is necessary, loosen the four bolts in thecarrier assembly, for the sprocket on the right side, andmove it to correct the alignment. The torque for thecarrier assembly bolts is 375 to 400 lb. ft. (510 to 540 Nm).EJECTORThe correct clearance between the bottom edge ofthe ejector and the scraper floor is .03 to .25 in. (0.8 to6.4 mm).EJECTOR1. Roller shafts. 2. Holes (in shafts). 3. Locknuts.If the clearance is not correct, loosen locknuts (3),then use a rod in the .44 in. (I 1.1 mm) diameter holesand turn roller shafts (1) to get the correct clearance.Tighten locknuts (3).NOTE: The center of the shaft diameter for the roller isnot in alignment with the center of the shaft diameter forroller adjustment. When roller shaft (I) is turned, theroller moves up and down the same distance the centersof the shaft are out of alignment.4-29
