<div style="text-align: justify;">In carrying-out disassembly, place the disassembled parts in order on a clean work table, and protect them against dust and dirt. Prepare various jigs necessary for removal depending on the type of machine.</div><div style="text-align: justify;"><br />

</div><div style="background-color: red; color: yellow; text-align: center;"><span style="font-size: large;">Fitting Of Bearing</span></div><br />
The bearing is to be fitted in the following manner<br />
<br />
<div style="background-color: yellow; color: red; text-align: center;"><span style="font-size: large;">Caution</span></div><br />
<br />
<div style="background-color: yellow; color: red; text-align: justify;">The anti-friction bearing is of higher precision than other mechanical parts, and so a due care is to be given to its handling to prevent them from becoming dusty, stained, scratched and marred.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Before fitting the bearing in position, its neck and threaded parts are to be made perfect, and cleaned completely by means of cleaning oil. the ring nut is to be temporarily fitted to the shaft beforehand to see if it is perfectly matched to it.</div><br />
<div style="text-align: justify;">The end cover, grease runner, ring nut and locking washer are to be cleaned beforehand.</div><br />
<div style="text-align: justify;">The bearing is to be heated in oil for expansion of its inner diameter.</div><br />
<br />
<div style="background-color: yellow; color: red; text-align: justify;">Caution: The heating temperature should not exceed 120ºC. The temperature higher than this will reduce the load tolerance of the bearing steel, thus resulting in the shorting of its durability.</div><br />
The heated bearing is to be set in place after the inside and cover has been fitted.<br />
<br />
<div style="text-align: justify;">The inner ring of the bearing is to be tightened fully against the shoulder part of the shaft after the ring nut has been tightened. After the bearing has cooled down to room temperature, the ring nut is to be tightened again and locked with a washer.</div><br />
<div style="text-align: justify;">Fill the space between the bearing races and the balls with grease. Inject grease into the inside end cover space, the grease amounting to 1/2 to 1/3 of the capacity.</div><br />
