hecking connecting rods squareness Figure 119 (Demonstration) 61 hecking axis alignment heck the alignment of the axes of the connecting rods ith a suitable device (5), proceeding as follows: the connecting rod (1) on the spindle of the tool (5) a ck it with the screw (4). t the spindle (3) on theV-prisms, resting the connecting r ) on the stop bar (2). 535 nd 1). he e. in 696 (1) nd od Checking torsion Figure 120 (Demonstration) 61694 Check the torsion of the connecting rod (5) by comparing two points (A and B) of the pin (3) on the horizontal plane of the axis of the connecting rod. Position the mount (1) of the dial gauge (2) so that this pre-loads by approx.
0.5 mm on the pin (3) at point A and zero the dial gauge (2). Shift the spindle (4) with the connecting rod (5) and compare any deviation on the opposite side B of the pin (3): the difference between A and B must be no greater than 0.08 mm. Checking bending Figure 121 (Demonstration) 61695 Check the bending of the connecting rod (5) by comparing two points C and D of the pin (3) on the vertical plane of the axis of the connecting rod. Position the vertical mount (1) ofthe dial gauge (2)so that this rests on the pin (3) at point C. Swing the connecting rod backwards andforwards seeking the highest position of the pin and in this condition zero the dial gauge (2).
Shift the spindle (4) with the connecting rod (5) and repeat the check on the highest point on the opposite side D of the pin (3). The difference between point C and point D must be no greater than 0.08 mm.
