Ideal gauge for checking bearing alignment or shaft deflection without dismantling the engine. Also useful as a strain gauge on engine frames. This inside measuring gauge checks the distortion of crankshaft webs and bears a direct relation to existing misalignment or excessive bearing wear. Used on all diesel engine shafts and centre crankshafts on any type of engine or compressor, the gauge can also be applied as a strain gauge on engine frames while the engine is operating. A comparison of readings taken at top and bottom positions indicates any misalignment of cylinder and frame which results in local over-stress and eventual cracking of the frame neck. With a special spring tension in the dial indicator, the gauge is self-sustaining in any position without sacrificing necessary rigidity, leaving the operator’s hands free. Hardened and ground to a sharp point, conical contact points have an approximate 60º included angle, and will stay in place on 45º surfaces
696B Balancing Attachment is furnished with the gauge. For certain applications, like turning the crank under test with the gauge in place, the attachment can be adjusted to maintain the face of the indicator upward or in desired position. To install on a strain gauge in use, remove the knurled clamping nut, then the doweled plate or end strap at either end by the screw. The unit is then positioned over the hubs on two sides of the indicator head. A spring plunger provides the friction that holds the balance in proper relation to position. The parts are nickel plated.The dial indicator movement is approximately 4mm and with rods and extension, provides a range from 61-458mm. There are 10 rods and one extension furnished. Rods are marked to designate the approximate overall length of the gauge. Indicator has a movable bezel to adjust the dial in relation to the hand and a non-breakable crystal. Designed in collaboration with Hartford Steam Boiler Inspection and Insurance Company. It was known as the Hartford Steam Boiler Engine Strain Gauge and isused by their inspectors to check the distortion of engine shafts and frames.
