1.  DISCONNECT MACHINE FROM POWER!

2.  Place a sheet of plywood or similar on top of 

table to protect the table (Figure 20), and 

open the grinding wheel cover.

When the wheel has been ring tested, and 

dressed, the wheel and hub must be removed and 

balanced as an assembly. However, remember 

that overtightening or rotating the spindle bolt in 

the incorrect direction can damage threads, crack 

the grinding wheel, and make grinding wheel 

removal more difficult than it needs to be.

When removing and installing the hub onto the 

spindle or balancing arbor, keep in mind that the 

mating surfaces between these components have 

the single most important effect on your final 

balancing results. Hubs, spindles, and balancing 

arbors can be easily damaged during installation 

and removal. Just one grain of sand, small burr, 

or hidden ding in either mating surface will 

undermine all balancing results. Make sure 

that all mating surfaces are carefully stoned to 

establish a perfect fit. 

NEVER pound on a hub or arbor for any reason. 

This will permanently displace metal and change 

high tolerance dimensions.

NEVER use a hydraulic press to install the 

balancing arbor or attempt to use a heat 

differential between parts to establish a shrink-

fit. This will change high tolerance dimensions. 

NEVER twist-fit the hub onto the spindle or 

the balancing arbor. Doing this can gall the 

tapered surfaces. Instead use a small arbor press 

with light pressure to install and remove the 

balancing arbor from the hub.

ALWAYS make sure that all mating surfaces 

are immaculately cleaned before hub or arbor 

installation. Use a lint-free photography lens 

cloth that is slightly oiled with a thin machine 

oil. For the best fit, the mating surfaces must 

be polished without having a wet layer of oil on 

them. The oil should only be in the pores of the 

metal.

3.  Position the spindle wrench on the spindle 

bolt (Figure 21).
