Interchanging Hydraulic Motors:

without Quick-Change option

In setting up for a different job, the hydraulic motor can be interchanged with a different model which may have a more favorable ratio of torque and speed for the new job.

  1. Remove four socket head cap screws.
  2. Pull out the motor with spline sleeve still attached.
    • The spline sleeve set screws are swedged in place and removal might be difficult.
    • It is recommended when using interchangeable motors, that you keep the spline sleeve attached and not to swap sleeves between motors.
    • If removal of sleeve is necessary, the swedge must be removed by deburring or a small end mill to remove swedge. Loosen set screws, and pull spline sleeve off of motor shaft.
    • Transfer motor adapter ring (if used) to new motor.
    • Place the spline sleeve on new motor shaft and tighten set screws.
  3. Plug the new motor assembly into the Jiffy-Tap body, engaging the spline sleeve with the spline on the spindle.
  4. Reinstall and tighten the four socket head cap screws.
