16.3 ALIGNING AN ELEMENT
If an element is no longer in line with the adjacent elements, the alignment can be
corrected as follows: (see fig. 22)
1. Loosen the four bolts/nuts A, that connect the crankshaft to the element.
2. Loosen the two bolts B, with which the element is connected to the frame.
3. Try to align the element by moving it sideways until it is in line with the adjacent
elements.
4. Re-tighten all the bolts and nuts.
@ The element can be pushed out of alignment through overloading.
@ Always realign an element whenever a crank is replaced so no extra tension is
created in the total element assembly.
@ Every pre-tension in the element assembly will reduce the life of the bearing and
can also damage other parts.
16.4 TIMING OF THE CRANK ELEMENTS
Figure 22 shows the timing of the crank elements. The timing is important because it
will determine the order in which the tines will go into the ground. The timing will,
therefore, determine the stability of the Verti-Drain
®
unit. It is, therefore, important
that when a component of the crankshaft is replaced that the timing is again the
same as in the old situation.
@ Consult the component page when maintenance takes place on the crankshaft to
ensure that the correct crankshaft components are used in the right place.
