Pulls seized bearing cups out of Class 7-8 truck driveshaft yokes with an impact gun, then seats new bolt-retained cups square on Spicer 1610-1880 joints.
This set pairs a 10102-pattern heavy-duty U-joint puller with a 5192-pattern bearing cup installer, the two tools a driveline shop reaches for when a Class 7 or 8 truck comes in with a worn or seized universal joint. The puller frame hooks over the yoke ears and a forcing screw, driven by up to a 1-inch impact wrench, pushes the cross through and walks the opposite bearing cup out of the yoke. The load stays square to the cup, so you are not hammering the yoke ears out of round on a part you plan to reuse.
Fitment goes by driveline series and bearing cup size rather than by truck. The puller handles bearing cups from 1.5 to 2.2 inches and covers Spicer 1610, 1710, 1760, 1810 and 1880 drivelines, Spicer SPL 140, 170 and 250 Life Series, Meritor (Rockwell) 16N, 17N, 18N and 1710, and Meritor RPL 20 and 25 Permalube joints. That is most over-the-road tractors, dump trucks and heavy equipment driveshafts.
The installer is for the reassembly side. On bolt-retained (bearing plate) U-joints, the cup has to go into the yoke bore lined up with the bolt holes or the needles get knocked loose and the joint fails early. Thread the two small alignment bolts into the yoke to locate the tool, then run in the center screw to press the cup home evenly. The cups end up seated and aligned, ready for the retaining bolts.
Both pieces are heavy carbon steel with a black finish. Shipping weight for the set is about 13.9 lb.
