Bridge Installation—Stationary Dyno

INSTALLING THE RUNNER MOUNTS AND RUNNER SUPPORTS
Refer to Appendix D for instructions on installing the bridge extension kit.
1 Place the runner mount (z-shaped) with eight round holes on top of the drum
guard.
Note: The standard runner mount is smaller than the extended runner mount
used with the bridge extension kit. Be sure to use the correct runner mount for
your installation.
2 Place the runner clamp plate with eight round holes on top of the runner mount.
3 Loosely secure each runner mount and runner clamp to the dyno using three
3/8 x 1.5-inch flange hex bolts.
4 Secure two runner support pillars to each runner support using two
1/2 x 3-inch hex bolts, lock washers, and nuts per support pillar.
Note: Use the inner holes on the runner support closest to the outside of the
dynos. Use the outer holes on the runner support closest to the center of the
dynos.
5 Stand up the runner support assemblies and place approximately 119.38 cm
(47.00 in.) from the stationary dyno.
Note: Do not secure the runner support to the floor at this time.
