(Refer to Taper Lock Bushing and Drive Motor Pulley Replacement on the previous page.) 9) Remove the taper lock bushings from the drive wheels. 10) Slide the pillow block bearings and taper lock bushing inward towards the gear (speed) reducer on the drive shaft. 11) Lift the end of the drive shaft closest to the rear of the dryer and pivot the other end of the shaft on the drive wheel until the shaft can be removed from the dryer. 12) To install new drive shaft, reverse Step #11 thru Step #2. 13) Reestablish electrical power to the dryer. e. Drive Wheel Replacement 1) Discontinue electrical power to the dryer. 2) Follow Step #2 thru Step #11 in the Drive Shaft Replacement instructions in the previous section (page 79 and page 80) for the removal of the drive wheels. IMPORTANT: Both drive wheels should be replaced as a set on the drive shaft assembly. 3) To replace the drive wheel assembly into the dryer, reverse Step #11 thru Step #2 in the Drive Shaft Replacement instructions in the previous section (page 79 and page 80). 4) Verify proper position of drive shaft components prior to tightening onto shaft. 5) Reestablish electrical power to the dryer. f. Pillow Block Bearing(s) Replacement 1) Discontinue electrical power to the dryer. 2) Follow Step #2 thru Step #11 in the instructions on page 79 and page 80. 3) Remove both drive wheels and taper lock bushings. 4) Carefully file the score marks on the drive shaft from the setscrews before removing the pillow block bearing(s). 5) To install new pillow block bearing(s), reverse Step #11 thru Step #2 in the instructions on page 79 and page 80. 6) Reestablish electrical power to the dryer. g. Gear (Speed) Reducer Replacement CAUTION: Replacement gear (speed) reducers are shipped without oil. Add proper amount (47 oz. [1.4 liters]) of recommended lubricant before operating. FAILURE TO OBSERVE THESE PRECAUTIONS WILL RESULT IN DAMAGE TO THE DRYER AND WILL VOID THE WARRANTY. CAUTION: Too much oil will cause overheating and too little oil will result in gear failure. Check oil level regularly. FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT IN DAMAGE TO THE DRYER AND WILL VOID THE WARRANTY. 1) Discontinue electrical power to the dryer. 2) Measure the distance of the gear (speed) reducer from the rear of the dryer to assist in positioning the gear (speed) reducer on the drive shaft during reinstallation. 3) Follow Step #2 thru Step #11 in the instructions on page 79 and page 80. 4) Remove the taper lock bushing and pillow block bearing from the drive shaft closest to the rear of the dryer. (Refer to the Taper Lock Bushing and Drive Motor Pulley Replacement section on page 79 for removal of the taper lock bushing). 5) Slide the gear (speed) reducer to the center of the drive shaft. 6) Check the position of the drain plug and the breather plug. 7) Check the turnbuckle mount pad on the gear (speed) reducer for the correct application. 8) Install the new gear (speed) reducer on the drive shaft along with the taper lock bushing, the pillow block bearing (setscrews in the pillow block bearing face the end of the drive shaft), the taper lock bushing, and the drive wheels. 81 9) Reinstall the drive shaft into the dryer. 10) Secure the gear (speed) reducer to the drive shaft by reinstalling the three (3) bolts into the taper lock bushing and tighten evenly for proper mounting. 11) Repeat Step #12 to reinstall the other taper lock bushing. 12) Reinstall the bolt into the turnbuckle and mounting bracket. 13) Reinstall V-belts and tighten turnbuckle. 14) Prior to operating new gear (speed) reducer, fill with (47 oz. [1.4 liters]) of SAE 90 gear oil. IMPORTANT: DO NOT OVERTIGHTEN TURNBUCKLE. 15) Mount the pillow block bearings onto the mounting pads (using the bolts that were removed)...DO NOT tighten. 16) Tighten the taper lock bushing into the drive wheels. 17) Tighten the adjustment bolts until the basket (tumbler) is centered. IMPORTANT: Remove the wooden blocks that were inserted under the basket (tumbler). 18) Tighten the bolts on the pillow block bearings. NOTE: Verify correct mounting position of the gear (speed) reducer. Make the necessary corrections and/or adjustments to the gear (speed) reducer for proper mounting. Changing the drain plug, breather plug, as well as the turnbuckle mounting pad may be required. NOTE: Inspect ALL of the work performed checking for security of parts and proper alignment. 19) Reestablish electrical power to the dryer. 3. Retaining Wheel Components a. Retaining Wheel Cover Panel Removal 1) Discontinue electrical power to the dryer. 2) Remove the top front panel to access the two (2) front retaining wheels and/or the rear top panel to access the two (2) rear retaining wheels. 3) To gain access to the bottom front retaining wheel the bottom panel must be removed. (The bolts securing this panel are located behind the right and left control panels.) NOTE: The lower front retaining wheel does not have a cover. NOTE: The guard panel must be remo...
