D is the distance between
straight edge and lower
outer hub edge
1. Place first element half on hubs and hand-tighten the flange head bolts. When tightening
the bolts, start at the center bolt hole and then install the bolts on the neighboring holes.
2. Place the second half of the element on the hubs and follow the same procedure. Hand-
tighten the flange head bolts.
3. Use a torque wrench to tighten all fasten-
ers for the E20 and E30 to these torque
values (same for both):

CHECKING COUPLING ALIGNMENT

Step 3 Verify Angular Alignment of Hubs
1. Measure the distance "B" between the hubs with calipers
or other appropriate tool at four places on the outer diam-
eter of the hub 90° apart.
2. Use the "B2" and "B1 " measurements to calculate "C"
by subtracting the smaller measurement from the larger
number, and do this for each of the 90° apart planes .
3. Adjust the engine isolators until the "C" measurements of
both planes do not exceed these Angular Values:

E30
Step 4 Verify Parallel Alignment of Hubs
1. Check parallel misalignment by placing a
D
straight edge across the outside diameter of the
hubs and measuring the gap between the
straight edge and the hub at four locations 90°
apart.
2. Adjust the engine isolators until the "D" meas-
urements do not exceed these Parallel Values.
