Route the belt around the pulleys as shown in Figure 16 on page 25.
2
Place the belt around the tensioner pulley and place the tensioner assembly in the
position shown in Figure 16 on page 25.
Standard Wheelbase—place the tensioner assembly 10.2 cm (4.0 in.) from the
outside of the rail.
Extended Wheelbase Option—place the tensioner assembly 12.7 cm (5.0 in.)
inside of the end of the rail.
Note:
Verify the welded on nuts on the tensioner assembly are towards the back
and the tensioner pulley is slid all the way to the end of the assembly towards the
stationary dyno.
3
Verify the belt is aligned and seated in the grooves on each pulley.
4
Verify the bearings are the same distance from each mounting angle.
5
Using a long straight edge, verify the tensioner pulley and the movable dyno
pulley are aligned.
6
With the tensioner assembly in this position, drill the eight holes needed to secure
the tensioner assembly to the floor.
7
Install eight Red Head anchors. Refer to
for installation instructions.
8
Secure the tensioner assembly to the floor using eight 3/8-16 x 1-inch bolts and
eight 3/8-inch flat washers.
