to engage and disengage the Linx belt drive.

collars of both bearings.

Note: A gap will remain between the splined shaft flange and outer shaft.
Note: The lock washer is comprised of two individual pieces. Should the washer
separate, verify the pieces go back together with the serrated edges facing
outward as shown in Figure 22.
12 Secure the cap screws with the shaft safety wire. Refer to Appendix C for
installation instructions.
Failure to secure the cap screws with safety wire can result in damage to the
dyno and/or the vehicle.
