retainers. Then lift out the thermometers. Re- 

 move the rubber bushings from the bulb ends 

 of the thermometers and the bushings from 

 the other ends of the thermometers. 



Place the longer bushings on the bulb end 

 of the new thermometers so they are flush 

 with the end of the thermometer holder. This 

 seals the small holes in the air intake when 

 it is slid into position. 



CAUTION: Position the rubber bushings on 

 the thermometer so the retaining clamps rest 

 on them. Otherwise, the pressure of the re- 

 taining clamps may break the thermometers. 



Replace the thermometers, positioning them 

 so the graduations are visible and both mer- 

 cury columns are magnified when viewed from 

 the same position. Replace and tighten the ther- 

 mometer retaining clamps.
