INSTALLING THE SAAR BRAKE ASSEMBLY
The following instructions are for installing the Spring Applied Air Brake Assembly on
a 224 above-ground or pit dyno.
In the next steps you will:
• attach the brake holder weldment using the brake clevis pin you removed
from the hydraulic brake assembly
• bolt the mounting bracket to the dyno
• slide the tube into place
• mount the air can assembly
• make the final connections
Note: If you have a 4 wheel drive dyno model 224-248 or 224-224, refer to
additional instructions for “Four Wheel Drive Dynos” on page 20.
I NSTALLING THE B RAKE W ELDMENT AND B RAKE S HOES
1 Slide the brake clevis pins into the square recesses as shown in Figure 11. Face
the head end of the pivot toward the outside, so that the brake clevis pin is
partially inside the recess and then slide the clevis pin partially into the mounting
bracket. The hole on the end of the brake clevis pin, which is designed to accept
the hairpin cotter, should be pointed toward the center of the dyno. Do not fully
insert the brake clevis pin until after you slide the brake weldment into position
2 Position the brake weldment so that the holes on the arms are aligned to accept
the brake clevis pin.
