There's a moment in every pitman arm job on a Sheppard M100 where you're standing back with a torch in one hand, deciding whether to risk it. The arm's welded itself to that tapered shaft over years of brake dust, road salt, and torque, and the usual fix? Heat, hammers, or a cutting wheel if the shift's running long — inconsistent, dangerous, and rough on anything you'd rather not replace. The 10385 is built around the exact geometry of the Sheppard M100 and HD94 gearboxes. It seats over the pitman arm, threads against the shaft, and pulls the arm straight off the taper the way the engineering intended. No heat, no swinging, no sparks bouncing across the bay. Replaces hammer and torch methods that put the steering shaft and your shoulders at risk Drives with up to a 3/4" impact for quick, controlled removal High-strength steel casting handles repeated high-capacity pulls without flexing or cracking Slides on cleanly — no adapters, no shimming, no improvising Pulls the arm without distorting the shaft or scrapping a reusable component Built for the job, sized for the gearbox, and ready when the next M100 comes through.
