INSTALLATION INSTRUCTIONS
6 x 3 and 8 x 3 Type H Brake Assemblies
Before installing this brake assembly, please take note:
These instructions show normal floor-mounted installation. The brake may alternately be wall- or ceiling-mounted if necessary.
The brake base mounting holes are not equal distances from the brake center. Mounting holes on the anti-drag side are 5-9/16" from the brake pin center. Mounting holes opposite the anti-drag side are 4-15/16" from the brake pin center. Be sure to position the brake over the correct mounting holes.
If necessary, the actuator ports may be rotated 180°. Temporarily drive out hinge pin to free actuator.
The brake must be installed with the actuator and hinge pins parallel with the brake base. If necessary, reposition brake by forcing against anti-drag friction.
The brake was correctly adjusted during factory inspection. Clamp nut A and adjusting nut B may be temporarily backed off to ease installation of brake on brake wheel.
BRAKE INSTALLATION
Install brake wheel.
Slip brake on brake wheel.
With clamp nut A loose, tighten adjusting nut B to clamp brake shoes tight against the brake wheel.
With actuator and hinge pins parallel with base (per item C above), and with brake wheel and brake pin center lines perpendicular, add shims between brake base and brake platform. Attach base with 5/8" bolts.
Using F-17 copper gasket seal, screw short thread end of armored hoses into both actuator ports. Wrench tighten to provide leak-proof hydraulic seals.
Use mounting brackets, lock washers and jam nuts provided to attach free ends of hoses to rigid support. Allow hose slack to permit movement of actuator.
The brake is now ready to be piped into the hydraulic system. Be sure to adjust the brake before operation.
BRAKE ADJUSTMENT
Start with brake shoes clamped tight against brake wheel per item 3.
Loosen adjusting nut B two and one half turns and tighten clamp nut A.
Both shoes should now be approximately 1/32" from brake wheel.
Follow "Brake Adjustment" instructions when readjustment is necessary to compensate for lining wear.
