Manufactured to precise tolerances, these hand-ground, individually produced pliers are designed to slip between opposite ends of the wheel axle and backside of truck journal boxes when the jaws are nearly closed. A special compression spring offers just the right amount of resistance when you squeeze the plier, gently spreading the truck journals apart and causing the wheel set to effortlessly slip from the truck. Re-installation of the wheel set is just as easy. Great for use with our Truck Tuner, (#82838, available separately). For HO standard gauge trucks only. Patent Pending.
