LUBRICATION AND ADJUSTMENT OF BEARINGS 57 



shaft with putty or clay and wrap the shaft at the bearings 

 with two or three thicknesses of common newspaper 

 smeared with cylinder oil. 



Cover the outside of the paper 

 with a good thick coating of 

 cylinder oil to prevent the bab- 

 bitt from clinging to the shaft. 



Make two boards similar to 

 Fig. 1 6 to hold the shaft central 

 in bearing while babbitting. The 

 holes in the boards are made the 

 size of the shaft and the three 

 blocks are nailed to the board 

 with ends on a circle to fit the 

 outside turned part of the can- 

 non-bearing. Put one board 

 "A" on shaft next to bevel-gear ; 

 then put bearing on shaft, and 

 the other board "A" on the 

 other end. Drive wooden plugs 

 through oil-holes until they 

 strike shaft. Set shaft and all 

 on end as shown in Fig. 17. 

 Make cup "B" of putty or clay 

 at opening in side of casting to 

 pour babbitt in ; also fill all around ends at "C" with putty 

 or clay to keep babbitt from running out. 



Heat babbitt just hot enough to run freely, and pour in
