Abstract
A gaging tool for checking the alignment of spaced apart holes located on a common axis, having particular utility for checking the alignment of bearing seats on half round yokes for universal joints. A pair of gage bushings are secured in the bearing seats by retaining straps. An alignment bar is passed through the internal gage bore of one of the bushings. When the bearing seats or holes are in alignment, the alignment bar will pass into the other of the pair of gage bushings.
Claims6
A gaging tool for determining if the half round bearing seats establishing the cross holes of a universal joint yoke are in alignment comprising, in combination:
- a pair of gage bushings each having an outside diameter corresponding to the diameter of the cross holes whose alignment is to be checked and a uniform internal gage bore;
- means for removably securing one gage bushing in one cross hole,
- means for removably securing the other gage bushing in the other cross hole;
- and
- a cylindrical alignment bar having a gaging portion spanning the distance between said cross holes, said gaging portion having an external diameter adapted to be closely received through the internal gage bore in each of said pair of gage bushings, said alignment bar being axially slidably and removably received through said gage bores of each of said pair of gage bushing only when said gage bores are in alignment and otherwise being axially slidable through only one gage bushing to thereby provide an indication of the alignment or lack of alignment of said cross holes.
