Disassembly For open lineshaft and enclosed lineshaft construction of the vertical turbine pump

For open lineshaft and enclosed lineshaft construction do the following:

a. Open Lineshaft Construction: each time a lineshaft coupling is exposed by removing a length of the column pipe, the lineshaft and the coupling must be removed by holding the coupling and turning the upper lineshaft in right hand direction (line shaft threads are left hand).

CAUTION：EQUIPMENT DAMAGE

• When using wrenches on shafting, always place the wrenches on the same side of the

shaft as illustrated in Figure 8-1 to avoid excess side strain on shafting.

• Always position the wrench that will grip the shaft above the shaft coupling (that is, on the

upper shaft as viewed when the vertical turbine pump is in the vertical installed position). This must be done to prevent scoring and burrs on the top ends of the shafting to allow bearings to slide on/off freely.

b. Enclosed Lineshaft Construction: each time a length of column pipe is removed the enclosing tube and lineshaft must also be disassembled. Locate the joint (refer to Figure 8-2) and unscrew (left hand threads) the enclosing tube from the lineshaft bearing (which acts as a bearing for the shaft and also as an enclosing tube coupling). Leave the lineshaft bearing threaded into the enclosing tube not being removed (to support the lineshaft). Slide the enclosing tube up to expose the lineshaft coupling and uncouple as outlined.
