Assemble complete brake group with no shims (1) under retainer (3).2. Put flange end of wheel spindle (4) down.3. Tighten three bolts (2) to a torque of 25 lb. ft. (35 N m) while turning spindle housing (6).4. Remove bolts (2) and retainer (3), but do not turn housing (6).5. Measure distance from end of spindle (4) to end of sprocket (5).6. Install shims (1) of this thickness less .005 to .010 in. (0.13 to 0.25 mm). If total shim thickness is more than .040 in. (1.02 mm), use a 9D7085 Shim as part of shim thickness needed. If total shim thickness is more than .060 in. (1.52 mm) use two 9D7085 Shims.7. Install retainer and bolts. Tighten bolts to a torque of 75 10 lb. ft. (100 14 N m).
