  3. Ordinary/Parallel Soft Foot

  4. Even gap between the foot and base. Ordinary/Parallel Soft Foot

  5. All four corners of the foot are on the same plane Ordinary/Parallel Soft Foot Even gap between the foot and base.

  6. Angular Soft Foot

  7. Angular Soft Foot A condition that refers to uneven or irregular gaps between the foot and base.

  8. Shim Pack Poorly machined/ sprung foot Angular Soft Foot A condition that refers to uneven or irregular gaps between the foot and base.

  9. Corroded and/or irregular base Angular Soft Foot A condition that refers to uneven or irregular gaps between the foot and base. Shim Pack Poorly machined/ sprung foot

  10. Angular Soft Foot A condition that refers to uneven or irregular gaps between the foot and base. Shim Pack Standard shim packs do not compensate for Angular Soft Foot.

  11. Angular Soft Foot Robs Productivity, Shortens Motor Life, and Increases Maintenance Demands

  12. Driven machine, originally in alignment, experiences shaft wobble when connected to improperly aligned motor. Angular Soft Foot Robs Productivity, Shortens Motor Life, and Increases Maintenance Demands

  13. Improperly aligned driver motor causes shaft wobble. Angular Soft Foot Robs Productivity, Shortens Motor Life, and Increases Maintenance Demands Driven machine, originally in alignment, experiences shaft wobble when connected to improperly aligned motor.

  14. Why is Angular Soft Foot so destructive?

  15. Why is Angular Soft Foot so destructive? Tightening a motor foot that has Angular Soft Foot forces the foot to make contact with the base, creating unwanted stresses on the motor housing through the motor’s leg. These stresses can distort the motor housing and twist bearings, bending the shaft and causing shaft wobble.

  16. Motor Twist & Foot Movement Tightening a motor foot that has Angular Soft Foot forces the foot to make contact with the base, creating unwanted stresses on the motor housing through the motor’s leg. These stresses can distort the motor housing and twist bearings, bending the shaft and causing shaft wobble.

These stresses can distort the motor housing and twist bearings, bending the shaft and causing shaft wobble.

  25. Angular Soft Foot will cause:

  26. Angular Soft Foot will cause: • extra strain on the bearings and seals • eccentricity of the motor air gap, reducing efficiency and increasing heat • excess strain and wear on couplings Ultimately, the result will be premature bearing failure and shorter motor life.

  27. How can you recognize Angular Soft Foot?

  28. How can you recognize Angular Soft Foot? Inconsistent flat rise readings during alignment indicate Angular Soft Foot. Check the gap under each corner of the foot with feeler gage. If the measurements are not the same, the motor may have an Angular Soft Foot condition.

  29. Have you ever “Chased Your Tail”? Correcting for Soft Foot based on inconsistent dial or laser readings may measure the spring of a foot

  30. Have you ever “Chased Your Tail”? Correcting for Soft Foot based on inconsistent dial or laser readings may measure the spring of a foot and not the actual ordinary, co-planar flat rise.

  31. Have you ever “Chased Your Tail”? Correcting for Soft Foot based on inconsistent dial or laser readings may measure the spring of a foot and not the actual ordinary, co-planar flat rise. Standard shimming simply lifts the problem

  32. Have you ever “Chased Your Tail”? Correcting for Soft Foot based on inconsistent dial or laser readings may measure the spring of a foot and not the actual ordinary, co-planar flat rise. Standard shimming simply lifts the problem, leading to a continual repetition of the process often called “chasing your tail”.

  33. What are the traditional cures for Angular Soft Foot? Step Shim (Labor intensive and can shake loose)

  38. Now, the most cost effective and practical solution to Angular Soft Foot is Sof’ Shoe shim.

  39. Poorly machined sprung foot Corroded and/or irregular base Shim Pack Now, the most cost effective and practical solution to Angular Soft Foot is Sof’ Shoe shim.

  40. Poorly machined sprung foot Corroded and/or irregular base Shim Pack Sof’ Shoe shim fills in any uneven gaps between the foot and base

  41. How does Sof’ Shoe shim work?

  42. How does Sof’ Shoe shim work? • It’s made of a specially formulated elastomer • Cold flows and sets to fill any irregular gaps between foot and base • Creates total surface contact • It is an “instant” step shim

  43. What makes Sof’ Shoe shims so effective?

  44. What makes Sof’ Shoe shims so effective? • Unique properties retain about 50% of it’s flexibility allowing it to conform to any shape • Takes a permanent set after ten to fourteen days under standard bolt torque compression • Enables instant motor startup after alignment • Stable to 225 degrees Fahrenheit
