Double Drum Sander 37 x 2

74

Reassembly Procedure

1.) To assemble the unit after replacing drums, install the sanding drum support brackets. Slide the drums through
the bearings but do not tighten the set screws in the bearings yet. Install the V-belt pulleys, but do not tighten the
set screws yet. 
2.) Remove the 2 x 6 from the conveyor bed currently. Align the cross brace and the dust cover currently. Install the
four bolts on the right (inboard) side. Install the on/off switch with the infeed bolts and two bolts on the left
(outboard) side of the sander and tighten securely. 
3.) Tighten the two set screws in each of the four bearing collars. Spin the drums by hand to check if they spin
freely. 
4.) Align the V-belt pulleys with the pulley on the motor and then tighten the set screws in the V-belt pulleys. Spin
the drums by hand to make sure the pulleys are in proper alignment. 
5.) Check the alignment of the front drum to the conveyor table. If they are not parallel, level the front and then the
rear drum (see pages 17 and 19) before proceeding further. 
6.) Readjust the tension of the V-belt by sliding the motor down and then tightening the pinch bolt in the motor
support casting. Make sure all pulleys are aligned and all bolts tight before using the sander. 
7.) Reinstall the outer belt guard using the two 5/16" x 1/2" screw. Reinstall the lower belt guard using the two 10-
24 screws and the middle, inner guard using two 10-24 screws.
