Monthly Inspection of Pierce Enforcer Engine

Monthly Inspection

• Park the loaded vehicle on flat level ground with wheels pointed straight and ensure parking brake is applied and wheels are chocked.
• Inspect the gap between the Rubber Axle Stop and spring, which should be between 1/16” and 1/2”. If outside of this range, drive cautiously and re-measure.
• If the gap is > 1/2”, place the vehicle out of service and contact CMF. If < 1/16” or the Rubber Axle Stop is touching, submit a defect report.

Brake Pads

• Bendix ADB22X Disc brake pads must be replaced at 11mm (approximately 7/16”).

• "S-buffers" in the front suspension stiffen the springs when compressed to reduce undesirable steering reaction during emergency braking.

Daily Inspection

• Inspect for loose hardware of the S-Buffer Assembly.
• Inspect welds and surrounding metal of the S-Buffer Assembly for cracks.
