The ZTSE4439 Pitman Arm Puller safely removes pitman arms from Sheppard M-Series steering gears (292, 392, 492 models) on heavy trucks. Applies controlled force to prevent bending, retainer damage, or housing marks—essential for steering gear replacement and linkage service in commercial fleets.

The Critical Risks of Improper Pitman Arm Removal in Heavy-Duty Trucks

Pitman arms on Sheppard M-Series steering gears are press-fit and often corroded—improper removal (hammering, prying) bends arms, damages retainers, or mars the steering box.

• Arm bending – Deformed arms cause $800–$2,000 replacement & alignment issues
• Retainer damage – Cracked retainers lead to $1,000–$3,000 steering gear repairs
• Housing scoring – Impact marks require $1,500–$4,000 resurfacing
• Downtime losses – Manual struggles extend service 3–6 hours, adding $600–$1,200 labor
• Steering misalignment – Poor removal causes handling issues, safety risks & $2,000–$5,000 fixes
• Full steering failure – Severe damage escalates to complete overhaul ($8,000–$20,000)
