ENCLOSURE 8 LUBRICATION
. Ball bearings have a light tap fit en the shaft, which means .CC01** to .0C02" press fit. The fit in the housing is a push fit. The bearing should be pulled with a puller or an arbor press whenever size. permits. Never press or hit ag: inst the outer race, balls or ball cage er ball bearings.
Oil Lubrication .-
Flush cut the housings thercughly with keresene er petroleum scivents. Fill the reservoir to the preper level as described belcw. If me pump is fitted with a constant level ciler check to see that the cil will be maintained at tne prcper teve!.
The level may be , adjusted by changing the height of the cress arms which sucpert the glass reservoir. Figure 10 shows the type of oil lubricated ball bearing usec. The housings are jacketed for ecoling water where conditions require it. The oil level
- should be maintained at the height indicated. When the hcusing is equipped with a sight glass peur oil into the top of the housing until level with the brass ring en the sight gf ass. Some pumps are equipped with ccnstant level cilers. The ccrrect level' will be maintained as long as they ccnform in the reservoir. Cn trico and similar cilers the oil level may be adjusted by changing the setting of the fevel regulating arms. .
Inscect the oil in the bearing periedically. Remember the cil requires frequent replenishment at normal temperatures and very frequent replenishment at high te m peratures. Oil is always subi ect to gradual deterioratien frem use and contamination frem dirt and meisture. In time the accumulated sludge will be harm'ul to the bearing and cause premature wear. For this ressen draining and flushing are necessary at regular intervals. It is gecd practice to change the cil after every 600 bcurs of cperaticn er more frequently if required.
