The ATC6450 is the professional heavy-duty solution for removing pitman arms from Sheppard M100 series steering gearboxes—engineered to deliver controlled, high-tonnage extraction force while protecting the steering box housing and linkage from collateral damage.

The Dangerous Risks of Improvised Pitman Arm Removal

Pitman arms on vocational trucks and buses are notoriously difficult to remove due to years of corrosion and high-torque press fits. Using "shop-made" methods like hammers or torches isn't just inefficient—it's dangerous to both the technician and the vehicle.

• Steering Gearbox Damage – Hammering on the pitman arm can mushroom the sector shaft or crack the gearbox housing ($1,500–$3,500 replacement).
• Linkage Distortion – Heat from a torch can compromise the metallurgy of steering links, leading to catastrophic failure on the road.
• Seal Failure – Excessive heat or vibration often ruins steering gear seals, causing immediate hydraulic leaks.
• Technician Injury – Improvised pullers can shatter under tension; the ATC6450 is built for safe, high-load use.
• Extended Downtime — Fighting a seized arm for 4 hours costs a fleet $500–$1,000 in lost revenue and labor.

What is the ATC6450 Pitman Arm Puller?

The ATC6450 Sheppard M100 Pitman Arm Puller is a precision-engineered tool designed to slip over the pitman arm and sector shaft. Compatible with up to a 3/4" impact tool, it applies even, axial force to break the corrosion bond instantly. It is the "10385 Style" equivalent required for professional service on Sheppard M80, M90, M100, and M110 gearboxes.
